Apparatus and method for turning e-book pages in portable terminal

BACKGROUND OF THE INVENTION

1. Field of the Invention

0001The present invention relates to a portable terminal. More particularly, the present invention relates to an apparatus and method for turning electronic book (e-book) pages in a portable terminal having an e-book function.

2. Description of the Related Art

0002Portable terminals are in trend of sudden spread owing to the convenience of carrying. Accordingly, service providers (i.e., system manufacturers) are competitively developing terminals having more special functions to guarantee many users. For example, the portable terminals are providing various functions of phone books, games, schedulers, short messages, the Internet, electronic mail (e-mail) messages, morning wakeup calls, MPEG-1 Audio Layer 3 (MP3) players, digital cameras, electronic dictionaries, e-books and the like.

0003Recently, an e-book, one of information provision media replacing a conventional paper book, is being introduced to show text contents in an electronic display manner. The e-book is of a scheme of, after storing text contents in a flash memory or a built-in hard disk, showing the stored text contents through a display screen. The e-book has an advantage of being capable of, after storing a large amount of book stories at a time, selecting and showing a wanted story.

0004At this time, the display screen can display only contents of a restricted region. Accordingly, to continuously seamlessly show the next story of the contents, a User Interface (UI) providing a page move or scroll function should be provided. Generally, the e-book can show a story of text contents on a screen while moving through a page up / page down function using a key input means provided in the e-book. Through this method, a user can read the full story of the text contents stored in the e-book.

0005However, a UI of a scheme of turning pages through key manipulation as above is merely of a direction control scheme of the most basic form and is not designed from an ergonomic viewpoint of making it convenient for a user to use. So, there is a problem that it is inconvenient for the user to convert pages of contents naturally.

SUMMARY OF THE INVENTION

0009It is an aim of certain embodiments of the invention to solve, mitigate, or obviate, at least partly, at least one of the problems and/or disadvantages associated with the prior art. Certain embodiments aim to provide at least one of the advantages described below.

0010Certain embodiments of the present invention aim to substantially solve at least the above problems and/or disadvantages and to provide at least the advantages below. Accordingly, certain embodiments of the present invention provide an apparatus and method for turning electronic book (e-book) pages in a portable terminal having an e-book function.

0011Certain embodiments of the present invention provide an apparatus and method for turning e-book pages in an analog manner, for enabling a user to convert pages of contents naturally with a feeling as if he/she really turns a book in a portable terminal having an e-book function.

0012According to a first aspect of the present invention, a method for turning electronic book (e-book) pages in a portable terminal having an e-book function is provided. The method comprising: displaying a page of an e-book on a screen of the portable terminal; detecting a touch in a right user interface, UI, activation region of the e-book or a left UI activation region of the e-book; displaying the right UI activation region or the left UI activation region on the at least one side of the e-book; displaying a number of page to be turned at a position adjacent to a drag on the right UI activation region or the left UI activation region, wherein the number of the page to be turned increases corresponding to the amount of the drag of the detected touch; moving to a page of the e-book corresponding to the number of the page according to releasing the drag; and displaying the moved page.

0013In a first disclosure a method for turning e-book pages in a portable terminal having an e-book function is provided. The method includes executing an e-book in the portable terminal, determining if a touch down is input more left than a predetermined right User Interface (UI) activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the right direction, and, when the touch down is input more left than the predetermined right UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the right direction, displaying the just preceding page on a screen.

0014In the context of this specification, a touch down may also be described as the touching, pressing, or making contact with a touch sensitive input means, such as a touch sensitive screen on which pages of the e-book are displayed, for example with a finger, stylus, or other suitable implement or tool. A touch down therefore corresponds to an event consisting of bringing a finger, stylus, implement or tool down into contact with the touch sensitive input means.

0015Similarly, a touch up may also be described as ceasing or terminating a touching of the touch sensitive input means. It represents the termination of a contact with the touch sensitive input means. In other words, a touch up is a disengagement from, or a release of the touch sensitive input means. A touch up therefore corresponds to an event consisting of bringing a finger, stylus, implement or tool away from the touch sensitive input means, breaking contact. A touch up can also be described as a lifting off, from the touch sensitive input means, of the finger, stylus, implement or tool.

0016In the context of this specification, a drag may also be described as the movement of a finger, stylus, implement or tool across a touch sensitive input means whilst maintaining contact with that input means. Typically, a drag will be preceded by, or begin with a touch down (contact is first made), and be followed by, or terminated by a touch up (contact is broken/released). Additionally, one drag event may immediately follow another, such that the end position of one drag is the start position of the next.

0017A drag in the right direction (a drag right) may be described as a drag which begins at a first position (start position) on the touch sensitive input means (e.g. the position at which a touch down occurs) and ends at a second position (end position) (e.g. the position at which a touch up occurs), where the second position is to the right of the first position (i.e. the second position is further right than the first position, but not necessarily directly to the right; the second position may additionally be above, level with, or below the first position). Similarly, a drag in the left direction (a drag left) may be described as one in which the end position is to the left (but not necessarily directly to the left) of the start position, a drag down may be described as one in which the end position is below (but not necessarily directly below - it could additionally be to the left or to the right of) the start position, and a drag up may be described as one in which the end position is above (but not necessarily directly above) the start position.

0018It will be appreciated that the step or feature of determining if a touch down is input more left than a predetermined right User Interface (UI) activation region of the e-book in certain embodiments comprises determining whether a position at which a touch sensitive screen (displaying one or more pages of the e-book) is initially touched (in the context of a touch, optional drag, and release sequence of events) is to the left of a predetermined area of the touch sensitive screen. The input of a touch down thus corresponds to performing a touch down, i.e. touching the touch sensitive input means.

0019In certain embodiments, the step or feature of then determining if, in a state where the touch down is input, a drag and touch up is input in the right direction, comprises determining whether, following a touch down and without releasing or breaking contact with the touch sensitive screen, a drag right is performed, followed by or terminated by a touch up (a release). As will be appreciated, the movement constituting the drag right may come to a halt before the touch up (i.e. the contacting finger, stylus etc. may be stationary with respect to the input means just before the touch up is performed), or alternatively, the touch up may be performed while the finger, stylus etc. is in motion across the touch sensitive input means. Thus, the touch up may comprise a lift at the end of a sweep across a touch sensitive screen. Inputting a drag and touch up thus corresponds to performing a drag and release.

0020In certain embodiments, displaying the just preceding page on a screen, comprises displaying on a screen (e.g. a touch sensitive screen) the page of an e-book immediately preceding the page that was displayed while the touch down (contact), drag, and touch up (release) operations were being performed.

0021In certain embodiments the method further comprises: <ul id="ul0001" list-style="none" compact="compact"><li>determining if a touch down is input more right than a predetermined left UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the left direction; and</li><li>when the touch down is input more right than the predetermined left UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left direction, displaying the just next page on the screen.</li></ul>

0022It will be appreciated that the step or feature of determining if a touch down is input more right than a predetermined left User Interface (UI) activation region of the e-book in certain embodiments comprises determining whether a position at which contact is made (i.e. initiated) with a touch sensitive screen (displaying the e-book) is to the right of a predetermined area of the touch sensitive screen.

0023In certain embodiments, the step or feature of then determining if, in a state where the touch down is input, a drag and touch up is input in the left direction, comprises determining whether, following a touch down and without releasing or breaking contact with the touch sensitive screen, a drag left is performed, followed by or terminated by a touch up (a release).

0024In certain embodiments a right partial region (a right portion) of the screen (e.g. the touch sensitive screen displaying the e-book pages) is defined as a right UI activation region, and a left partial region (left portion) of the screen is defined as a left UI activation region.

0025In certain embodiments the method further comprises: <ul id="ul0002" list-style="none" compact="compact"><li>determining if a touch down is input in the predetermined right UI activation region of the e-book (e.g. a predetermined right portion of a touch sensitive screen displaying the e-book);</li><li>when the touch down is input in the predetermined right UI activation region of the e-book, displaying the right side of the e-book (e.g. displaying at least a right page, e.g. page number R, of the e-book open at the appropriate position, i.e. a current, or currently selected position);</li><li>determining if a drag and touch up is input in the left direction in a state where the touch down is input in the predetermined right UI activation region (i.e. is the drag performed after the touch down is performed, without releasing/breaking contact); and</li><li>when the drag and touch up is input in the left direction in the state where the touch down is input in the predetermined right UI activation region, displaying the just next page on the screen (e.g. displaying the page immediately following the page that was displayed while the touch down, drag, and touch up were being performed, i.e. page number R+1). In other words, a virtual page turn of one page forwards is performed.</li></ul>

0026In certain embodiments, the method further comprises: <ul id="ul0003" list-style="none" compact="compact"><li>determining if a drag is input in the right direction in the state where the touch down is input in the predetermined right UI activation region (i.e. determining if, following a touch down in the right UI activation region, a drag right is performed without breaking contact with the touch sensitive input means);</li><li>when the drag is input in the right direction in the state where the touch down is input in the predetermined right UI activation region, displaying the number of pages increasing as much as the dragging on the right side of the e-book (e.g. displaying a representation of a plurality of pages following on from the currently displayed right page, the number N of said plurality of pages being determined by a length of the drag right, such as a difference between nominal X coordinates of the end and start positions of the drag right);</li><li>determining if a drag and touch up is input in the left direction in the state where the drag is input in the right direction (i.e. determining if a drag left is performed after the drag right, without breaking contact in between); and</li><li>when the drag and touch up is input in the left direction in the state where the drag is input in the right direction, displaying a next page corresponding to the number of the increased pages (e.g. displaying a page corresponding to the last of said plurality of pages, or displaying a page appropriate or corresponding to a vitual turn of N pages).</li></ul>

0027It will be appreciated that, in certain embodiments, displaying the number of pages comprises displaying just edge portions (right hand edges) of the N pages. If the right hand page displayed in response to the touch down is page number R, then the drag right determines the number N of following pages displayed (i.e. represented), and in certain embodiments the drag left then results in the page number R+N being displayed.

0028In certain embodiments, the method further comprises: <ul id="ul0004" list-style="none" compact="compact"><li>when a touch down is input in the predetermined left UI activation region of the e-book (e.g. in a predetermined left portion of a touch sensitive screen displaying the e-book), displaying the left side of the e-book (e.g. displaying at least a left page, number L, of the e-book open at the appropriate position, i.e. a current, or currently selected position);</li><li>determining if a drag and touch up is input in the right direction in the state where the touch down is input in the predetermined left UI activation region (i.e. determining if, following a touch down in the left UI activation region, a drag right is performed without breaking contact with the touch sensitive input means); and</li><li>when the drag and touch up is input in the right direction in the state where the touch down is input in the predetermined left UI activation region, displaying the just preceding page on the screen (e.g. the immediately preceding page, number L-1).</li></ul>

0029In certain embodiments the method further comprises: <ul id="ul0005" list-style="none" compact="compact"><li>determining if a drag is input in the left direction in the state where the touch down is input in the predetermined left UI activation region (i.e. is the drag left performed, after the touch down, without breaking contact);</li><li>when the drag is input in the left direction in the state where the touch down is input in the predetermined left UI activation region, displaying the number of pages decreasing as much as the dragging on the left side of the e-book (e.g. displaying a representation of a plurality of pages preceding the currently displayed page, number L, the number N of said plurality of pages being determined by a length of the drag left, such as a difference between nominal X coordinates of the end and start positions of the drag right);</li><li>determining if a drag and touch up is input in the right direction in a state where the drag is input in the left direction (i.e. determining if a drag right is performed after the drag left, without breaking contact in between); and</li><li>when the drag and touch up is input in the right direction in the state where the drag is input in the left direction, displaying a preceding page corresponding to the number of the decreased pages (e.g. displaying a page corresponding to the first (earliest, lowest numbered) of said plurality of pages, or displaying a page appropriate or corresponding to a vitual turn of N pages).</li></ul>

0030It will be appreciated that, in certain embodiments, displaying the number of pages comprises displaying just edge portions (left hand edges) of the N pages. If the left hand page displayed in response to the touch down is page number L, then the drag left determines the number N of preceding pages displayed (i.e. represented), and in certain embodiments the drag right then results in the page number L-N being displayed.

0031In certain embodiments the method further comprises: <ul id="ul0006" list-style="none" compact="compact"><li>determining if a bookmark On switch (e.g. a portion of a touch sensitive input means, such as a screen, designated as a bookmark On switch) is touched in a predetermined upper UI activation region of the e-book; and</li><li>when the bookmark On switch is touched in the predetermined upper UI activation region of the e-book, activating a bookmark function.</li></ul>

0032In certain embodiments, the method further comprises: <ul id="ul0007" list-style="none" compact="compact"><li>determining if a touch down is input in the predetermined upper UI activation region of the e-book and then, in a state where the touch down is input, a drag is input in the downward direction (i.e. is a drag down performed, following the touch down, without breaking contact);</li><li>when the touch down is input in the predetermined upper UI activation region of the e-book and then, in the state where the touch down is input, the drag is input in the downward direction, generating a clip (e.g. an image or representation of a clip) corresponding to a bookmark to be added;</li><li>determining if a touch up is input in the state where the drag is input in the downward direction (e.g. is the drag down followed by, or terminated by, a touch up); and</li><li>when the touch up is input in the state where the drag is input in the downward direction, positioning the generated clip in a position where the touch up is input.</li></ul>

0033In certain embodiments, the method further comprises: <ul id="ul0008" list-style="none" compact="compact"><li>determining if a touch down is input for a clip corresponding to a previously added bookmark in the e-book (e.g. determining if the postion of the touch down corresponds to the position of a previously generated clip);</li><li>when the touch down is input for the clip corresponding to the previously added bookmark in the e-book, displaying a corresponding bookmark page;</li><li>determining if a long touch (e.g. a continuous touch longer than a predetermined threshold period of time) is sensed for the clip whose bookmark page has been displayed; and</li><li>when the long touch is sensed for the clip whose bookmark page has been displayed, displaying information on the previously added bookmark.</li></ul>

0034In certain embodiments, the method further comprises: <ul id="ul0009" list-style="none" compact="compact"><li>determining if a touch down is input for a clip corresponding to a previously added bookmark in the e-book;</li><li>when the touch down is input for the clip corresponding to the previously added bookmark in the e-book, displaying a corresponding bookmark page;</li><li>determining if a drag and touch up is input in the left/right direction in a state where the touch down is input for the clip whose bookmark page has been displayed; and</li><li>when the drag and touch up is input in the left/right direction in the state where the touch down is input for the clip whose bookmark page has been displayed, moving to the bookmark page corresponding to the previously added bookmark.</li></ul>

0035Thus, in certain embodiments, depending on the direction of the drag, a virtual page turn is performed, either to the immediately preceding or immediately following bookmarked page.

0036In certain embodiments, the method further comprises: <ul id="ul0010" list-style="none" compact="compact"><li>determining if a touch down is input for a clip corresponding to a previously added bookmark in the e-book and then, in a state where the touch down is input, a drag and touch up is input in the upward direction; and</li><li>when the touch down is input for the clip corresponding to the previously added bookmark in the e-book and then, in the state where the touch down is input, the drag and touch up is input in the upward direction, deleting a clip corresponding to the previously added bookmark.</li></ul>

0037In a second disclosure a method for turning electronic book (e-book) pages is provided, the method comprising: <ul id="ul0011" list-style="none" compact="compact"><li>executing an e-book with a portable terminal having a touch sensitive screen for displaying pages of the e-book;</li><li>displaying a page of the e-book on said screen;</li><li>detecting a touch on the screen followed by a drag to the left or right, and a release;</li><li>displaying the next page of the e-book on the screen if the drag is to the left; and</li><li>displaying the preceding page of the e-book on the screen if the drag is to the right.</li></ul> Embodiments of this second disclosure may additionally incorporate any of the features of the first disclosure or its embodiments.

0038In accordance with a second aspect of the present invention, an apparatus for turning electronic book (e-book) pages in a portable terminal having an e-book function is provided. The apparatus comprising: an e-book viewer for executing an e-book, controlling a display unit to display a page of the e-book; and a controller configured to: detect a touch in a right user interface, UI, activation region of the e-book or a left UI activation region of the e-book; display the right UI activation region or the left UI activation region on the at least one side of the e-book; display a number of page to be turned at a position adjacent to a drag on the right UI activation region or the left UI activation region, wherein the number of the page to be turned increases_corresponding to the amount of the drag of the detected touch; move to a page of the e-book corresponding to the number of the page according to releasing the drag; and display the moved page.

0039In a third disclosure an apparatus for turning e-book pages in a portable terminal having an e-book function is provided. The apparatus includes an e-book viewer and a display unit. The e-book viewer executes an e-book, determines if a touch down (e.g. on a touch sensitive input means, such as a touch sensitive screen displaying the e-book pages) is input more left than a predetermined right UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the right direction and, when the touch down is input more left than the predetermined right UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the right direction, controls a display unit to display the just preceding page on a screen. The display unit displays, on the screen, a corresponding page of the e-book according to the control of the e-book viewer.

0040As will be appreciated, in certain embodiments the e-book viewer comprises a processor adapted to execute an e-book application or program.

0041In a fourth disclosure a method for turning e-book pages in a portable terminal having an e-book function is provided. The method includes executing an e-book, displaying a shortcut item list in a predetermined upper UI activation region of the e-book, determining if a touch down is input for one shortcut item among the shortcut item list (e.g. determining if an area or region displaying said one shortcut item is touched) and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction (i.e. is a drag, to the left or right, performed after the touch down, without breaking contact), and, when it is determined that the touch down is input for the one shortcut item among the shortcut item list and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, displaying, on a screen, a page corresponding to the one shortcut item.

0042In certain embodiments, the method further comprises: <ul id="ul0012" list-style="none" compact="compact"><li>determining if a touch down is input for one shortcut item among the shortcut item list and then, in a state where the touch down is input, a drag and touch up is input in the downward direction; and</li><li>when the touch down is input for the one shortcut item among the shortcut item list and then, in the state where the touch down is input, the drag and touch up is input in the downward direction, displaying, on the screen, a sub item list of the (i.e. corresponding to the) one shortcut item.</li></ul>

0043In certain embodiments, the method further comprises: <ul id="ul0013" list-style="none" compact="compact"><li>determining if a touch down is input for one sub item among the displayed sub item list and then, in a state where the touch down is input, a touch up is input; and</li><li>when the touch down is input for the one sub item among the displayed sub item list and then, in the state where the touch down is input, the touch up is input, displaying a page corresponding to the one sub item on the screen.</li></ul>

0044Thus, in certain embodiments, if a touch down on an area displaying a particular sub-item is performed, followed by a touch up (release), without an intervening drag, then a page corresponding to that sub item is displayed.

0045In certain embodiments, the method further comprises: <ul id="ul0014" list-style="none" compact="compact"><li>determining if a touch down is input for one sub item among the displayed sub item list and then, in a state where the touch down is input, a drag and touch up is input in the upward direction; and</li><li>when the touch down is input for the one sub item among the displayed sub item list and then, in the state where the touch down is input, the drag and touch up is input in the upward direction, removing the displaying of the sub item list of the one shortcut item on the screen.</li></ul>

0046In certain embodiments, the method further comprises: <ul id="ul0015" list-style="none" compact="compact"><li>determining if a touch down is input in the upper UI activation region and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction; and</li><li>when the touch down is input in the upper UI activation region and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, displaying, on the screen, as much next/previous shortcut item list as the dragging in the upper UI activation region (e.g. if the drag is to the left, a next, following portion of the shortcut item list is displayed, the size of that portion being determined by a length of the drag to the left, and if the drag is to the right, a preceding portion of the shortcut item list is displayed, the size of that portion being determined by a length of the drag to the right).</li></ul>

0047In certain embodiments, the method further comprises: <ul id="ul0016" list-style="none" compact="compact"><li>determining if a multi touch down is input (e.g. is the touch sensitive input means, such as a screen, touched in a plurality of different positions simultaneously) in the upper UI activation region and then, in a state where the multi touch down is input, a drag and touch up is input;</li><li>when the multi touch down is input in the upper UI activation region and then, in the state where the multi touch down is input, the drag and touch up is input, determining if a distance value between points where the multi touch down is input increases (e.g. determining if the separation of the touched points increases);</li><li>when it is determined that the distance value between the points where the multi touch down is input increases, displaying a shortcut item list of an enlarged size corresponding to the increased distance value in the upper UI activation region of the screen; and</li><li>when it is determined that the distance value between the points where the multi touch down is input decreases (e.g. the touched points get closer together as the result of the drag - which may be a drag from one or both of the initially touched points, in the event that the number of touch downs is two), displaying a shortcut item list of a reduced size corresponding to the decreased distance value in the upper UI activation region of the screen.</li></ul>

0048In other words, in certain embodiments, the size of the displayed shortcut item list may be increased or decreased according to whether, following a touch down at two points simultaneously, the touched positions are dragged apart or together respectively.

0049In certain embodiments, the method further comprises: <ul id="ul0017" list-style="none" compact="compact"><li>determining if a long touch (i.e. a touch having a duration greater than a predetermined threshold value) is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book;</li><li>when the long touch is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book, determining if it is a state where a sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book;</li><li>when it is determined that it is not the state where the sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book, displaying the sub item list of the one shortcut item in a size smaller than the shortcut item list between the one shortcut item and a next shortcut item in the upper UI activation region of the e-book; and</li><li>when it is the state where the sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book, removing the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book.</li></ul>

0050In a fifth disclosure an apparatus for turning e-book pages in a portable terminal having an e-book function is provided. The apparatus includes an e-book viewer and a display unit. The e-book viewer executes an e-book, controls a display unit to display a shortcut item list in a predetermined upper UI activation region of the e-book and, when a touch down is input for one shortcut item among the shortcut item list and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction, controls the display unit to display, on a screen, a page corresponding to the one shortcut item. The display unit displays the shortcut item list in the predetermined upper UI activation region according to the control of the e-book viewer, and displays, on the screen, a corresponding page of the e-book.

0051Again, in certain embodiments the e-book viewer comprises a processor adapted to execute an e-book application or program.

0052In certain embodiments the e-book viewer determines if a touch down is input for one shortcut item among the shortcut item list and then, in a state where the touch down is input, a drag and touch up is input in the downward direction, and when the touch down is input for the one shortcut item among the shortcut item list and then, in the state where the touch down is input, the drag and touch up is input in the downward direction, controls the display unit to display, on the screen, a sub item list of the one shortcut item.

0053In certain embodiments the e-book viewer determines if a touch down is input for one sub item among the displayed sub item list and then, in a state where the touch down is input, a touch up is input, and when the touch down is input for the one sub item among the displayed sub item list and then, in the state where the touch down is input, the touch up is input, controlling the display unit to display a page corresponding to the one sub item on the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

0061Preferred embodiments of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. And, terms described below, which are defined considering functions in the present invention, can be different depending on user and operator's intention or practice. Therefore, the terms should be defined on the basis of the disclosure throughout this specification.

0062Exemplary embodiments of the present invention provide a way of turning electronic book (e-book) pages in an analog manner in a portable terminal having an e-book function.

0063In the following description, portable terminals are meaning inclusive of all of a cellular phone with a touch panel, a Personal Communication System (PCS), a Personal Data Assistant (PDA), an International Mobile Telecommunication - 2000 (IMT-2000) terminal and the like. The following description is made using general constructions of the examples.

0064<figref idref="f0001">FIG. 1</figref> is a block diagram illustrating an apparatus construction of a portable terminal having an e-book function according to the present invention.

0065As illustrated in <figref idref="f0001">FIG. 1</figref>, the portable terminal includes a controller 100, a memory 102, an input unit 104, a display unit 106, an e-book viewer 108, and a communication unit 110.

0066Referring to <figref idref="f0001">FIG. 1</figref>, the controller 100 controls a general operation of the portable terminal, and processes a function of turning e-book pages in an analog manner according to the present invention.

0067The memory 102 stores a microcode of a program for processing and controlling the controller 100 and a variety of reference data, temporary data generated in execution of a variety of programs, and a diversity of updateable depository data. Particularly, the memory 102 stores a program for turning e-book pages in an analog manner according to the present invention.

0068The input unit 104 has numeral key buttons and a plurality of function key buttons. The input unit 104 provides key button input data corresponding to a key button pressed by a user to the controller 100.

0069The display unit 106 displays state information generated during operation of the portable terminal, limited number of characters, a large amount of moving pictures and still pictures and the like. In addition to common functions, according to the present invention, the display unit 106 is formed in a form of a touch panel and performs a function of the input unit 104. That is, the display unit 106 senses a user's touch input and transmits the sensed touch input to the controller 100.

0070The e-book viewer 108 performs a role of turning an e-book by one page / by several pages in an analog manner such that a user can convert pages of contents naturally with a feeling as if he/she really turns a book. Further, the e-book viewer 108 supports a bookmark for the e-book.

0071The communication unit 110 performs a function of transmitting/receiving and processing a wireless signal input/output through an antenna. For example, in a transmission mode, the communication unit 110 performs a function of processing original data through channel coding and spreading, converting the original data into a Radio Frequency (RF) signal, and transmitting the RF signal. In a reception mode, the communication unit 110 performs a function of processing a received RF signal through de-spreading and channel decoding, and restoring the signal to original data.

0072<figref idref="f0002">FIG. 2</figref> is an example diagram illustrating a method for turning an e-book by one page in an analog manner in a portable terminal having an e-book function according to a first exemplary embodiment of the present invention.

0073Referring to <figref idref="f0002">FIG. 2</figref>, the terminal executes the e-book function, and displays, on a screen, a preset page of an e-book selected by a user. Here, a right partial region of the screen is defined as a right UI activation region, and a left partial region of the screen is defined as a left UI activation region. Here, the right UI activation region and the left UI activation region are preset suitable to a corresponding terminal.

0074As in <figref idref="f0002">FIG. 2A</figref>, if a touch down is input more left than the predetermined right UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the right direction, the terminal displays the just preceding page on the screen. As in <figref idref="f0002">FIG. 2B</figref>, if a touch down is input more right than the predetermined left UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the left direction, the terminal displays the just next page on the screen.

0075<figref idref="f0003">FIG. 3</figref> is a flowchart illustrating a method for turning an e-book by one page in an analog manner in a portable terminal having an e-book function according to a first exemplary embodiment of the present invention.

0076Referring to <figref idref="f0003">FIG. 3</figref>, in step 301, the terminal determines if a request for execution of an e-book function is sensed according to user's key manipulation.

0077When it is determined in step 301 that the request for execution of the e-book function is sensed, in step 303, the terminal executes the e-book function and, according to setting information of the e-book function, displays a preset page of an e-book selected by a user. For example, the setting information of the e-book function can be preset to display the first page of a corresponding e-book or display the previously last displayed page of the corresponding e-book at the time of execution of the e-book function.

0078After that, in step 305, the terminal determines if a touch down is input more left than a predetermined right UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the right direction.

0079When it is determined in step 305 that the touch down is input more left than the predetermined right UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the right direction, in step 307, the terminal displays the just preceding page on the screen.

0080In contrast, when it is not determined in step 305 that the touch down is input more left than the predetermined right UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the right direction, in step 309, the terminal determines if a touch down is input more right than a predetermined left UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the left direction.

0081When it is determined in step 309 that the touch down is input more right than the predetermined left UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left direction, in step 311, the terminal displays the just next page on the screen.

0082In contrast, when it is not determined in step 309 that the touch down is input more right than the predetermined left UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left direction, the terminal returns to step 305 and repeatedly performs the subsequent steps.

0083After that, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0084<figref idref="f0004">FIG. 4</figref> is an example diagram illustrating a method for turning an e-book by several pages in an analog manner in a portable terminal having an e-book function according to a second exemplary embodiment of the present invention.

0085Referring to <figref idref="f0004">FIG. 4</figref>, the terminal executes the e-book function, and displays, on a screen, a preset page of an e-book selected by a user. Here, a right partial region of the screen is defined as a right UI activation region, and a left partial region of the screen is defined as a left UI activation region. Here, the right UI activation region and the left UI activation region are preset suitable to a corresponding terminal.

0086If a touch down is input in the predetermined right UI activation region of the e-book, the terminal displays the right side of the e-book. At this time, as in <figref idref="f0004">FIG. 4A</figref>, if a drag and touch up is input in the left direction in a state where the touch down is input in the predetermined right UI activation region, the terminal displays the just next page on the screen. In contrast, as in <figref idref="f0004">FIG. 4B</figref>, if a drag is input in the right direction in a state where the touch down is input in the predetermined right UI activation region, the terminal displays the number of pages increasing as much as the dragging on the right side of the e-book and, if a drag and touch up is input in the left direction in a state where the drag is input in the right direction, the terminal displays a next page corresponding to the number of the increased pages.

0087Although not illustrated, if a touch down is input in the predetermined left UI activation region of the e-book, the terminal displays the left side of the e-book. At this time, if a drag and touch up is input in the right direction in a state where the touch down is input in the predetermined left UI activation region, the terminal displays the just preceding page on the screen. In contrast, if a drag is input in the left direction in the state where the touch down is input in the predetermined left UI activation region, the terminal displays the number of pages decreasing as much as the dragging on the left side of the e-book and, if a drag and touch up is input in the right direction in a state where the drag is input in the left direction, the terminal displays a preceding page corresponding to the number of the decreased pages.

0088<figref idref="f0005">FIGS. 5A</figref> and <figref idref="f0006">5B</figref> are a flowchart illustrating a method for turning an e-book by several pages in an analog manner in a portable terminal having an e-book function according to a second exemplary embodiment of the present invention.

0089Referring to <figref idref="f0005">FIGS. 5A</figref> and <figref idref="f0006">5B</figref>, in step 501, the terminal determines if a request for execution of an e-book function is sensed according to user's key manipulation.

0090When it is determined in step 501 that the request for execution of the e-book function is sensed, in step 503, the terminal executes the e-book function and, according to setting information of the e-book function, displays a preset page of an e-book selected by a user. For example, the setting information of the e-book function can be preset to display the first page of a corresponding e-book or display the previously last displayed page of the corresponding e-book at the time of execution of the e-book function.

0091After that, in step 505, the terminal determines if a touch down is input in a predetermined right UI activation region of the e-book.

0092When it is determined in step 505 that the touch down is input in the predetermined right UI activation region of the e-book, in step 507, the terminal displays the right side of the e-book, and proceeds to step 509.

0093Next, in step 509, the terminal determines if a drag and touch up is input in the left direction in a state where the touch down is input in the predetermined right UI activation region.

0094When it is determined in step 509 that the drag and touch up is input in the left direction in the state where the touch down is input in the predetermined right UI activation region, in step 511, the terminal displays the just next page on the screen.

0095In contrast, when it is not determined in step 509 that the drag and touch up is input in the left direction in the state where the touch down is input in the predetermined right UI activation region, in step 513, the terminal determines if a drag is input in the right direction in the state where the touch down is input in the predetermined right UI activation region.

0096When it is determined in step 513 that the drag is input in the right direction in the state where the touch down is input in the predetermined right UI activation region, in step 515, the terminal displays the number of pages increasing as much as the dragging on the right side of the e-book and then, proceeds to step 517. Here, the number of pages displayed on the right side increases more and more fast according to the dragging.

0097After that, in step 517, the terminal determines if a drag and touch up is input in the left direction in the state where the drag is input in the right direction.

0098When it is determined in step 517 that the drag and touch up is input in the left direction in the state where the drag is input in the right direction, in step 519, the terminal displays a next page corresponding to the number of the increased pages.

0099When it is determined in step 517 that the drag and touch up is not input in the left direction in the state where the drag is input in the right direction, in step 518, the terminal determines if, in the state where the drag is input in the right direction, a drag is continuously input in the right direction.

0100When it is determined in step 518 that, in the state where the drag is input in the right direction, the drag is continuously input in the right direction, the terminal returns to step 515 and repeatedly performs the subsequent steps.

0101In contrast, when it is determined in step 518 that, in the state where the drag is input in the right direction, the drag is not continuously input in the right direction, the terminal terminates the algorithm according to the exemplary embodiment of the present invention. For example, in the state where the drag is input in the right direction, when a touch up is input without a drag of the left direction or right direction, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0102In contrast, when it is determined in step 513 that the drag is not input in the right direction in the state where the touch down is input in the predetermined right UI activation region, the terminal returns to step 509 and repeatedly performs the subsequent steps.

0103In contrast, when it is determined in step 505 that the touch down is not input in the predetermined right UI activation region of the e-book, in step 521, the terminal determines if a touch down is input in a predetermined left UI activation region of the e-book.

0104When it is determined in step 521 that the touch down is input in the predetermined left UI activation region of the e-book, in step 523, the terminal displays the left side of the e-book, and proceeds to step 525.

0105After that, in step 525, the terminal determines if a drag and touch up is input in the right direction in the state where the touch down is input in the predetermined left UI activation region.

0106When it is determined in step 525 that the drag and touch up is input in the right direction in the state where the touch down is input in the predetermined left UI activation region, in step 527, the terminal displays the just preceding page on the screen.

0107In contrast, when it is determined in step 525 that the drag and touch up is not input in the right direction in the state where the touch down is input in the predetermined left UI activation region, in step 529, the terminal determines if a drag is input in the left direction in the state where the touch down is input in the predetermined left UI activation region.

0108When it is determined in step 529 that the drag is input in the left direction in the state where the touch down is input in the predetermined left UI activation region, in step 531, the terminal displays the number of pages decreasing as much as the dragging on the left side of the e-book and then, proceeds to step 533. Here, the number of pages displayed on the left side decreases more and more fast according to the dragging.

0109Next, in step 533, the terminal determines if a drag and touch up is input in the right direction in the state where the drag is input in the left direction.

0110When it is determined in step 533 that the drag and touch up is input in the right direction in the state where the drag is input in the left direction, in step 535, the terminal displays a preceding page corresponding to the number of the decreased pages.

0111In contrast, when it is determined in step 533 that the drag and touch up is not input in the right direction in the state where the drag is input in the left direction, in step 534, the terminal determines if, in the state where the drag is input in the left direction, a drag is continuously input in the left direction.

0112When it is determined in step 534 that, in the state where the drag is input in the left direction, the drag is continuously input in the left direction, the terminal returns to step 531 and repeatedly performs the subsequent steps.

0113In contrast, when it is determined in step 534 that, in the state where the drag is input in the left direction, the drag is not continuously input in the left direction, the terminal terminates the algorithm according to the exemplary embodiment of the present invention. For instance, in the state where the drag is input in the left direction, when a touch up is input without a drag of the left direction or right direction, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0114In contrast, when it is determined in step 529 that the drag is not input in the left direction in the state where the touch down is input in the predetermined left UI activation region, the terminal returns to step 525 and repeatedly performs the subsequent steps.

0115In contrast, when it is determined in step 521 that the touch down is not input in the predetermined left UI activation region of the e-book, the terminal returns to step 505 and repeatedly performs the subsequent steps.

0116After that, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0117On the other hand, an e-book function according to the present invention can be executed in various modes according to user's key manipulation. For example, the e-book function can be executed in a bookmark mode supporting a bookmark, a concavo-convex mode supporting shortcut and the like. Hereinafter, the execution of the e-book function of the bookmark mode supporting the bookmark is described by way of a third exemplary embodiment, and the execution of the e-book function of the concavo-convex mode supporting the shortcut is described by way of a fourth exemplary embodiment.

0118<figref idref="f0007">FIG. 6</figref> is an example diagram illustrating a method for supporting a bookmark for an e-book in a portable terminal having an e-book function according to a third exemplary embodiment of the present invention.

0119Referring to <figref idref="f0007">FIG. 6</figref>, the terminal executes the e-book function and displays, on a screen, a preset page of an e-book selected by a user. After that, the terminal touches a bookmark On/Off switch to activate a bookmark function. At this time, an upper partial region of the screen is defined as an upper UI activation region, and the upper UI activation region is preset suitable to a corresponding terminal. The bookmark On/Off switch for activation/deactivation of the bookmark function can be positioned left in the predetermined upper UI activation region of the e-book. For example, the bookmark On/Off switch can be displayed in a clip shape. Further, a menu for automatically storing a position before moving to a bookmark page corresponding to a clip can be positioned right in the predetermined upper UI activation region of the e-book. For example, the menu can be displayed in an arrow shape.

0120As in <figref idref="f0007">FIG. 6A</figref>, if a touch down is input in the predetermined upper UI activation region of the e-book and then, in a state where the touch down is input, a drag is input in the downward direction, the terminal determines that there is a request for addition of a bookmark, and generates a clip corresponding to a bookmark to be added. Here, a position of the clip can move along a drag direction until before a touch up is input in a state where the drag is input in the downward direction. After that, if a touch up is input in the state where the drag is input in the downward direction, the terminal positions the generated clip in a position where the touch up is input. Here, a shape, color and the like of the generated clip can be set according to preset information. As a different method, the terminal may position the generated clip in a position where the touch up is input and simultaneously, display an input window through a popup window, receive an input of information of a shape, color and the like of the generated clip from a user, and change the shape, color and the like of the generated clip according to the received information.

0121As in <figref idref="f0007">FIG. 6B</figref>, if a touch down is input for a clip corresponding to a previously added bookmark, the terminal displays a corresponding bookmark page. If a long touch is sensed for the clip corresponding to the previously added bookmark, whose bookmark page has been displayed, the terminal determines that there is a request for displaying of information on the previously added bookmark, and displays the information on the previously added bookmark through a popup window. Here, the long touch represents a continuous touch for one or two seconds, and the information on the bookmark can include information of a generation date of the bookmark, a generation time, a bookmark page and the like. Further, the popup window can display not only information on a corresponding bookmark but also a memo menu for memo composition and a move menu for position change of the bookmark. In this case, if the memo menu is selected from a user, the terminal can display a memo window and receive an input of memos to be written about the bookmark. If the move menu is selected from the user, the terminal can perform a bookmark position change mode and receive an input of a changed position of a clip corresponding to the bookmark.

0122Although not illustrated, if a touch down is input for a clip corresponding to a previously added bookmark, the terminal displays a corresponding bookmark page. If a drag and touch up is input in the left/right direction in a state where the touch down is input for the clip corresponding to the previously added bookmark, whose bookmark page has been displayed, the terminal determines that there is a request for movement to the bookmark page corresponding to the previously added bookmark, and moves to the bookmark page.

0123Although not illustrated, if a touch down is input for a clip corresponding to a previously added bookmark and then, in a state where the touch down is input, a drag and touch up is input in the upward direction, the terminal determines that there is a request for removal of the previously added bookmark, and deletes a clip corresponding to the previously added bookmark.

0124<figref idref="f0008">FIGS. 7A</figref> and <figref idref="f0009">7B</figref> are a flowchart illustrating a method for supporting a bookmark for an e-book in a portable terminal having an e-book function according to a third exemplary embodiment of the present invention.

0125Referring to <figref idref="f0008">FIGS. 7A</figref> and <figref idref="f0009">7B</figref>, in step 701, the terminal determines if a request for execution of an e-book function is sensed according to user's key manipulation.

0126When it is determined in step 701 that the request for execution of the e-book function is sensed, in step 703, the terminal executes the e-book function and, according to setting information of the e-book function, displays a preset page of an e-book selected by a user. For example, the setting information of the e-book function can be preset to display the first page of a corresponding e-book or display the previously last displayed page of the corresponding e-book at the time of execution of the e-book function.

0127Next, in step 705, the terminal determines if a bookmark On switch is touched (i.e., touch up after touch down). Here, the bookmark On switch can be, for example, positioned left in a predetermined upper UI activation region of the e-book, and can be displayed in a clip shape. According to another exemplary embodiment of the present invention, the bookmark On switch may be realized as one switch performing all of the function of a bookmark On switch and the function of a bookmark Off switch. In this case, in a case where the switch is touched in a bookmark Off state, the switch can transit to a bookmark On state to activate a bookmark function. In a case where the switch is touched in the bookmark On state, the switch can transit to the bookmark Off state to deactivate the bookmark function.

0128When it is determined in step 705 that the bookmark On switch is touched, in step 707, the terminal activates the bookmark function and then, proceeds to step 709.

0129Next, in step 709, the terminal determines if a touch down is input in the predetermined upper UI activation region of the e-book and then, in a state where the touch down is input, a drag is input in the downward direction.

0130When it is determined in step 709 that the touch down is input in the predetermined upper UI activation region of the e-book and then, in the state where the touch down is input, the drag is input in the downward direction, the terminal determines that there is a request for addition of a bookmark and, in step 711, generates a clip corresponding to a bookmark to be added and proceeds to step 713. Here, a position of the clip can move along a drag direction until before a touch up is input in a state where the drag is input in the downward direction.

0131Next, in step 713, the terminal determines if a touch up is input in the state where the drag is input in the downward direction.

0132When it is determined in step 713 that the touch up is input in the state where the drag is input in the downward direction, in step 715, the terminal positions the generated clip in a position where the touch up is input, and terminates the algorithm according to the exemplary embodiment of the present invention. Here, a shape, color and the like of the generated clip can be set according to preset information. As a different method, the terminal may position the generated clip in the position where the touch up is input and simultaneously, display an input window through a popup window, receive an input of information of the shape, color and the like of the generated clip from a user, and change the shape, color and the like of the generated clip according to the received information.

0133In contrast, when it is determined in step 709 that the touch down is input in the predetermined upper UI activation region of the e-book and then, in the state where the touch down is input, the drag is not input in the downward direction, in step 717, the terminal determines if a touch down is input for a clip corresponding to a previously added bookmark.

0134When it is determined in step 717 that the touch down is input for the clip corresponding to the previously added bookmark, in step 718, the terminal displays a corresponding bookmark page, and proceeds to step 719.

0135Next, in step 719, the terminal determines if a long touch is sensed for the clip corresponding to the previously added bookmark, whose bookmark page has been displayed. Here, the long touch represents a continuous touch for one or two seconds, for example.

0136When it is determined in step 719 that the long touch is sensed for the clip corresponding to the previously added bookmark, whose bookmark page has been displayed, the terminal determines that there is a request for displaying of information on the previously added bookmark, whose bookmark page has been displayed and, in step 720, displays the information on the previously added bookmark through a popup window and terminates the algorithm according to the exemplary embodiment of the present invention. Here, the information on the bookmark can include information of a generation date of the bookmark, a generation time, a bookmark page and the like. Further, the popup window can display not only information on a corresponding bookmark but also a memo menu for memo composition and a move menu for position change of a corresponding bookmark. In this case, if the memo menu is selected from a user, the terminal can display a memo window and receive an input of memos to be written about the bookmark. If the move menu is selected from the user, the terminal can perform a bookmark position change mode and receive an input of a changed position of a clip corresponding to the bookmark.

0137In contrast, when it is determined in step 719 that the long touch is not sensed for the clip corresponding to the previously added bookmark, whose bookmark page has been displayed, in step 721, the terminal determines if a drag and touch up is input in the left/right direction in a state where the touch down is input for the clip corresponding to the previously added bookmark.

0138When it is determined in step 721 that the drag and touch up is input in the left/right direction in the state where the touch down is input for the clip corresponding to the previously added bookmark, the terminal determines that there is a request for movement to the bookmark page corresponding to the previously added bookmark, which has been displayed and, in step 722, moves to the bookmark page and terminates the algorithm according to the exemplary embodiment of the present invention.

0139In contrast, when it is determined in step 721 that the drag and touch up is not input in the left/right direction in the state where the touch down is input for the clip corresponding to the previously added bookmark, in step 723, the terminal determines if a touch up is input in the state where the touch down is input for the clip corresponding to the previously added bookmark.

0140When it is determined in step 723 that the touch up is input in the state where the touch down is input for the clip corresponding to the previously added bookmark, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0141In contrast, when it is determined in step 723 that the touch up is not input in the state where the touch down is input for the clip corresponding to the previously added bookmark, the terminal returns to step 719 and repeatedly performs the subsequent steps.

0142In contrast, when it is determined in step 717 that the touch down is not input for the clip corresponding to the previously added bookmark, in step 725, the terminal determines if a touch down is input for a clip corresponding to a previously added bookmark and then, in a state where the touch down is input, a drag and touch up is input in the upward direction (e.g., till the end of the upward direction).

0143When it is determined in step 725 that the touch down is input for the clip corresponding to the previously added bookmark and then, in the state where the touch down is input, the drag and touch up is input in the upward direction, the terminal determines that there is a request for removal of the previously added bookmark and, in step 727, the terminal deletes the clip corresponding to the previously added bookmark and terminates the algorithm according to the exemplary embodiment of the present invention.

0144In contrast, when it is determined in step 725 that the touch down is input for the clip corresponding to the previously added bookmark and then, in the state where the touch down is input, the drag and touch up is not input in the upward direction, the terminal returns to step 709 and repeatedly performs the subsequent steps.

0145Next, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0146<figref idref="f0010">FIG. 8</figref> is an example diagram illustrating a method for supporting shortcut for an e-book in a portable terminal having an e-book function according to a fourth exemplary embodiment of the present invention.

0147Referring to <figref idref="f0010">FIG. 8</figref>, the terminal executes the e-book function and displays, on a screen, a preset page of an e-book selected by a user. After that, a shortcut On/Off switch is touched to activate a shortcut function. At this time, an upper partial region of the screen is defined as an upper UI activation region, and the upper UI activation region is preset suitable to a corresponding terminal. The shortcut On/Off switch for activation/deactivation of the shortcut function can be positioned left in the predetermined upper UI activation region of the e-book. For example, the shortcut On/Off switch can be displayed in a document shape. Further, a menu for automatically storing a position before moving to a page corresponding to a shortcut item can be positioned right in the predetermined upper UI activation region of the e-book. For example, the menu can be displayed in an arrow shape. Here, the shortcut item, which is an item enabling quick movement to a corresponding page according to user's key manipulation, is arranged in predefined order in the upper UI activation region of the e-book. For example, the shortcut item can be composed of a chapter intended for quick move, a table, a picture, a page and the like.

0148As in <figref idref="f0010">FIG. 8A</figref>, if a touch down is input for one shortcut item among a shortcut item list displayed in the upper UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction, the terminal determines if there is a request for shortcut to a corresponding page, and displays the page corresponding to the one shortcut item. Or, if a touch down is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in a state where the touch down is input, a drag and touch up is input in the downward direction, as in <figref idref="f0010">FIG. 8B</figref>, the terminal displays a sub item list of the one shortcut item on a screen through a popup window. For example, in a case where the one shortcut item is Chapter 5, the sub item list can be composed of Chapters 5-1, 5-2, 5-3 and the like and, in the popup window, the sub item list, a title of each sub item and the like can be displayed.

0149<figref idref="f0011">FIG. 9</figref> is an example diagram illustrating a method for supporting shortcut for an e-book in a portable terminal having an e-book function according to a fourth exemplary embodiment of the present invention.

0150Referring to <figref idref="f0011">FIG. 9</figref>, as in <figref idref="f0011">FIG. 9A</figref>, if a touch down is input in an upper UI activation region of an e-book and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction, the terminal displays as much next/previous shortcut item list as the dragging in the upper UI activation region of a screen. For example, in a case where a shortcut item list currently displayed on a screen is Chapters 4, 5, 6, and 7, the terminal can display Chapters 2, 3, 4, and 5 listed in a previous shortcut item list, according to the dragging on the screen.

0151As in <figref idref="f0011">FIG. 9B</figref>, if a multi touch down is input in an upper UI activation region of an e-book and then, in a state where the multi touch down is input, a drag and touch up is input, the terminal determines if a distance value between points where the multi touch down is input increases. If it is determined that the distance value increases, the terminal displays a shortcut item list of an enlarged size corresponding to the increased distance value in the upper UI activation region of a screen. If it is determined that the distance value decreases, the terminal displays a shortcut item list of a reduced size corresponding to the decreased distance value in the upper UI activation region of the screen. For example, in a case where the shortcut item list currently displayed on the screen is Chapters 4, 5, 6, and 7, among them, Chapters 5 and 6 can be displayed in the enlarged size on the screen.

0152<figref idref="f0012">FIGS. 10A</figref> and <figref idref="f0013">10B</figref> are a flowchart illustrating a method for supporting shortcut for an e-book in a portable terminal having an e-book function according to a fourth exemplary embodiment of the present invention.

0153Referring to <figref idref="f0012">FIGS. 10A</figref> and <figref idref="f0013">10B</figref>, in step 1001, the terminal determines if a request for execution of an e-book function of a concavo-convex mode is sensed according to user's key manipulation. This can be determined by identifying if a touch (i.e., touch up after touch down) for a shortcut On switch is sensed. Here, the shortcut On switch can be, for example, positioned left in a predetermined upper UI activation region of an e-book, and can be displayed in a document shape. According to another exemplary embodiment, the shortcut On switch may be realized as one switch performing all of the function of a shortcut On switch and the function of a shortcut Off switch. In this case, in a case where a user touches the switch in a shortcut Off state, the switch transits to a shortcut On state and accordingly, a shortcut function is activated and the e-book function of the concavo-convex mode is executed. In a case where the user touches the switch in the shortcut On state, the switch transits to the shortcut Off state and accordingly, the shortcut function is deactivated and the e-book function of the concavo-convex mode is execution-terminated.

0154When the request for execution of the e-book function of the concavo-convex mode is sensed in step 1001, in step 1003, the terminal executes the e-book function in the concavo-convex mode supporting the shortcut.

0155After that, in step 1005, the terminal displays a preset page of an e-book selected by a user according to setting information of the e-book function, and displays a shortcut item list in the upper UI activation region of the e-book. For example, the setting information of the e-book function can be preset to display the first page of a corresponding e-book or display the previously last displayed page of the corresponding e-book at the time of execution of the e-book function.

0156Next, in step 1007, the terminal determines if a touch down is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book according to user's key manipulation and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction. Here, by distinguishing the one shortcut item and the remnant shortcut items through colors, patterns and the like, the terminal can inform a user that the touch down is input for the one shortcut item. Further, the terminal can inform the user that the touch down is input for the one shortcut item, through a voice, a vibration and the like.

0157When it is determined in step 1007 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, the terminal determines that there is a request for shortcut to a corresponding page and, in step 1009, displays the page corresponding to the one shortcut item on a screen and then, returns to step 1007 and repeatedly performs the subsequent steps. Here, the terminal can inform a user of quick moving to the page corresponding to the one shortcut item, through a voice, a vibration and the like.

0158In contrast, when it is not determined in step 1007 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, in step 1011, the terminal determines if a touch down is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book according to user's key manipulation and then, in a state where the touch down is input, a drag and touch up is input in the downward direction.

0159When it is determined in step 1011 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the downward direction, in step 1013, the terminal displays a sub item list of the one shortcut item on the screen through a popup window and then, proceeds to step 1015. For example, in a case where the one shortcut item is Chapter 5, the sub item list can be composed of Chapters 5-1, 5-2, 5-3 and the like and, in the popup window, the sub item list, a title of each sub item and the like can be displayed.

0160Next, in step 1015, the terminal determines if a touch down is input for one sub item among the sub item list displayed on the screen through the popup window according to user's key manipulation and then, in a state where the touch down is input, a touch up is input. Here, by distinguishing the sub item for which the touch down is currently input and the remnant sub items among the sub item list through colors, patterns and the like, the terminal can inform a user of the sub item for which the touch down is currently input. Further, the terminal can inform the user of information on the sub item for which the touch down is currently input among the sub item list, through a voice, a vibration and the like. For example, the terminal can output "Title of Chapter 5-1 is [Understanding of Physics]", through a voice.

0161When it is determined in step 1015 that the touch down is input for the one sub item among the sub item list displayed on the screen through the popup window and then, in the state where the touch down is input, the touch up is input, in step 1017, the terminal displays a page corresponding to the one sub item on the screen. Here, the terminal can inform a user of quick moving to the page corresponding to the one sub item.

0162In contrast, when it is determined in step 1015 that the touch down is input for the one sub item among the sub item list displayed on the screen through the popup window and then, in the state where the touch down is input, the touch up is not input, in step 1019, the terminal determines if a touch down is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book according to user's key manipulation and then, in a state where the touch down is input, a touch up is input.

0163When it is determined in step 1019 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the touch up is input, the terminal returns to step 1013 and repeatedly performs the subsequent steps.

0164In contrast, when it is determined in step 1019 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the touch up is not input, in step 1021, the terminal determines if a touch down is input for one sub item among the sub item list displayed on the screen through the popup window according to user's key manipulation and then, in a state where the touch down is input, a drag and touch up is input in the upward direction.

0165When it is determined in step 1021 that the touch down is input for the one sub item among the sub item list displayed on the screen through the popup window according to the user's key manipulation and then, in the state where the touch down is input, the drag and touch up is input in the upward direction, in step 1023, the terminal removes the displaying of the sub item list of the one shortcut item through the popup window on the screen and then, returns to step 1007 and repeatedly performs the subsequent steps. Here, the terminal can inform a user of removing the displaying of the sub item list of the one shortcut item through the popup window on the screen, through a voice, a vibration and the like. Or, as a different method, the terminal may determine if a touch down is input for the remnant regions excepting a region of a screen where a sub item list is displayed and then, in a state where the touch down is input, a touch up is input and, in a case where the touch down is input for the remnant regions excepting the region of the screen where the sub item list is displayed and then, in a state where the touch down is input, a touch up is input, the terminal may remove the displaying of the sub item list of the one shortcut item through the popup window on the screen.

0166In contrast, when it is determined in step 1021 that the touch down is input for the one sub item among the sub item list displayed on the screen through the popup window and then, in the state where the touch down is input, the drag and touch up is not input in the upward direction, the terminal returns to step 1015 and repeatedly performs the subsequent steps.

0167In contrast, when it is determined in step 1011 that the touch down is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is not input in the downward direction, in step 1025, the terminal determines if a long touch is input for one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book according to user's key manipulation.

0168When it is determined in step 1025 that the long touch is input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book according to the user's key manipulation, in step 1027, the terminal determines if it is a state where a sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book according to user's key manipulation.

0169When it is determined in step 1027 that it is not the state where the sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book, in step 1029, the terminal displays the sub item list of the one shortcut item in the upper UI activation region of the e-book and then, returns to step 1007 and repeatedly performs the subsequent steps. For example, as in <figref idref="f0015">FIG. 11</figref>, the sub item list of the one shortcut item can be displayed in a size smaller than the shortcut item list between the one shortcut item and a next shortcut item. Here, the terminal can inform a user of displaying a sub item list of the one shortcut item in the upper UI activation region of the e-book, through a voice, a vibration and the like.

0170In contrast, when it is determined in step 1027 that it is the state where the sub item list of the one shortcut item is being displayed in the upper UI activation region of the e-book, in step 1031, the terminal removes the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book and then, returns to step 1007 and repeatedly performs the subsequent steps. Here, the terminal can inform a user of removing the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book, through a voice, a vibration and the like.

0171In contrast, when it is determined in step 1025 that the long touch is not input for the one shortcut item among the shortcut item list displayed in the upper UI activation region of the e-book, in step 1033, the terminal determines if a touch down is input in the upper UI activation region of the e-book according to user's key manipulation and then, in a state where the touch down is input, a drag and touch up is input in the left/right direction.

0172When it is determined in step 1033 that the touch down is input in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, in step 1035, the terminal displays as much next/previous shortcut item list as the dragging in the upper UI activation region of the screen and then, returns to step 1007 and repeatedly performs the subsequent steps. For example, in a case where the shortcut item list currently displayed on the screen is Chapters 4, 5, 6 and 7, Chapters 2, 3, 4, and 5 listed in a previous shortcut item list can be displayed according to the dragging on the screen. Here, the terminal can inform a user of moving to the next/previous shortcut item list, through a voice, a vibration and the like.

0173In contrast, when it is not determined in step 1033 that the touch down is input in the upper UI activation region of the e-book and then, in the state where the touch down is input, the drag and touch up is input in the left/right direction, in step 1037, the terminal determines if a multi touch down is input in the upper UI activation region of the e-book according to user's key manipulation and then, in a state where the multi touch down is input, a drag and touch up is input.

0174When it is determined in step 1037 that the multi touch down is input in the upper UI activation region of the e-book and then, in the state where the multi touch down is input, the drag and touch up is input, in step 1039, the terminal determines if a distance value between points where the multi touch down is input increases.

0175When it is determined in step 1039 that the distance value between the points where the multi touch down is input increases, in step 1041, the terminal displays a shortcut item list of an enlarged size corresponding to the increased distance value in the upper UI activation region of the screen and then, returns to step 1007 and repeatedly performs the subsequent steps. Here, the terminal can inform a user of the displaying of the shortcut item list of the enlarged size, through a voice, a vibration and the like. For example, in a case where the shortcut item list currently displayed on the screen is Chapters 4, 5, 6, and 7, among them, Chapters 5 and 6 can be displayed in the enlarged size on the screen.

0176In contrast, when it is determined in step 1039 that the distance value between the points where the multi touch down is input decreases, in step 1043, the terminal displays a shortcut item list of a reduced size corresponding to the decreased distance value in the upper UI activation region of the screen and then, returns to step 1007 and repeatedly performs the subsequent steps. Here, the terminal can inform a user of the displaying of the shortcut item list of the reduced size, through a voice, a vibration and the like. For example, in a case where the shortcut item list currently displayed on the screen is Chapters 4, 5, 6, and 7, Chapters 2, 3, 4, 5, 6, 7, 8, and 9 can be displayed in the reduced size on the screen.

0177In contrast, when it is determined in step 1037 that the multi touch down is input in the upper UI activation region of the e-book and then, in the state where the multi touch down is input, the drag and touch up is not input, the terminal returns to step 1007 and repeatedly performs the subsequent steps.

0178Next, the terminal terminates the algorithm according to the exemplary embodiment of the present invention.

0179<figref idref="f0015">FIG. 11</figref> is an example diagram illustrating a method for supporting shortcut for an e-book in a portable terminal having an e-book function according to a fourth exemplary embodiment of the present invention.

0180Referring to <figref idref="f0015">FIG. 11</figref>, if a long touch is input for one shortcut item among a shortcut item list displayed in an upper UI activation region of an e-book as in <figref idref="f0015">FIG. 11A</figref>, the terminal displays a sub item list of the one shortcut item in the upper UI activation region of the e-book as in <figref idref="f0015">FIG. 11B</figref>. For example, the sub item list of the one shortcut item can be displayed in a size smaller than the shortcut item list between the one shortcut item and a next shortcut item. Here, the terminal can inform a user of the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book, through a voice, a vibration and the like.

0181Although not illustrated, if a long touch is input for one shortcut item in a state where a sub item list of the one shortcut item is displayed in an upper UI activation region of an e-book, the terminal removes the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book. Here, the terminal can inform a user of removing the displaying of the sub item list of the one shortcut item in the upper UI activation region of the e-book, through a voice, a vibration and the like.

0182As described above, exemplary embodiments of the present invention have an advantage that, although not learning an equipment use method, a user can convert pages of contents naturally with a feeling as if he/she really turns a book, by providing a UI of turning e-book pages in an analog manner in a portable terminal having an e-book function.
