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

BACKGROUND

OF THE INVENTION

1. Field of the Invention

The 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

Portable 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.

Recently, 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.

At 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.

However, 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

It 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.

Certain 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.

Certain 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.

According 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 includes executing an e-book, 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.

It will be appreciated that executing the e-book can also be described as executing, running, or carrying out the instructions of an e-book application or program.

In 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.

Similarly, 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.

In 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.

A 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.

It 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.

In 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.

In 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.

In 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>

It 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.

In 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).

In 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.

In 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>

In 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 virtual turn of N pages).</li></ul>

It 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.

In 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>

In 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 virtual turn of N pages).</li></ul>

It 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.

In 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>

In 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>

In 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 position 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>

In 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>

Thus, 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.

In 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>

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred 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.

Exemplary 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.

In 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.

<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.

As 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.

Referring 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.

The 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.

The 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.

The 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.

The 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.

The 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.

<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 an exemplary embodiment of the present invention.

Referring 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.

As 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.

<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 an exemplary embodiment of the present invention.

Referring 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.

When 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.

After 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.

When 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.

In 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.

When 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.

In 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.

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

<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 an exemplary embodiment of the present invention.

Referring 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.

If 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.

Although 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.

<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 an exemplary embodiment of the present invention.

Referring 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.

When 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.

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

When 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.

Next, 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.

When 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.

In 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.

When 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.

After 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.

When 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.

When 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.

When 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.

In 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.

In 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.

In 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.

When 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.

After 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.

When 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.

In 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.

When 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.

Next, 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.

When 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.

In 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.

When 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.

In 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.

In 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.

In 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.

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

<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 an exemplary embodiment of the present invention.

Referring 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.

As 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.

As 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.

Although 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.

Although 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 deletion of the previously added bookmark, and deletes a clip corresponding to the previously added bookmark.

<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 an exemplary embodiment of the present invention.

Referring 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.

When 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.

Next, 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.

When 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.

Next, 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.

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 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.

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

When 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.

In 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.

When 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.

Next, 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.

When 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.

In 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.

When 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.

In 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.

When 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.

In 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.

In 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).

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 input in the upward direction, the terminal determines that there is a request for deletion 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.

In 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.

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