<p num="0005"> By the way, in the electronic book device, even if vibration is generated in response to the operation on the touch panel, it merely makes the user recognize that the finger is in contact with the touch panel, and even if the operation can be grasped. , It is difficult to represent the state where the page is turned. Further, in the electronic book device, even if the vibration intensity is changed, for example, the vibration intensity for each position of the touch panel is only set in advance, and the page turning state cannot be grasped. ..</p><p num="0006"> In an electronic book, for example, the position at which the user starts the turning operation and the position at which the user determines that the turning operation has been completed and releases the finger from the touch panel differ depending on the user, and also differs each time the turning operation is performed. Therefore, if the vibration intensity is uniformly set for the position specified on the touch panel, it only gives the user the feeling of operating the electronic device, and gives the user the feeling of turning the page. Is difficult to give.</p><p num="0007"> In addition, with a touch panel, for example, due to the strength of the sensor sensitivity, the page cannot be turned when the user's finger is near the display surface, or when the finger is released from the touch panel after the turning operation, or the page cannot be turned to the previous page. It may come back. Therefore, the user needs to visually check the content of the displayed image in order to determine whether or not the target page has been turned, which causes a problem that the user feels annoyed.</p><p num="0008"> Therefore, in view of the above problems, the technical object of the present disclosure is to make the user grasp the operation state of the page switching operation of the electronic book apparatus.</p>

0014[First Embodiment]

0015FIG. 1 is a diagram showing a configuration example of an electronic book apparatus according to the first embodiment. The electronic book device 2 reads, for example, stored electronic book data and displays a page formed by including characters and images. Further, the electronic book apparatus 2 has a function of switching to the next page according to an input operation for the displayed contents. That is, the electronic book apparatus 2 has at least a display function, an input operation function, and a function of giving the user an operation feeling for the page switching operation. The electronic book device 2 includes, for example, an information processing terminal device such as a PC (Personal Computer), a smartphone or a tablet (Tablet), a mobile phone, a portable game machine, and the like.

0016The electronic book apparatus 2 includes, for example, a storage unit 4, a display unit 6, an input unit 8, a vibration unit 12, and a control unit 14.

0017The storage unit 4 is an example of a means for storing information detected in an electronic book program or an operation by a user. The storage unit 4 may be formed, for example, inside the housing of the electronic book apparatus 2, or may be formed by an removable external storage means. In addition, the storage unit 4 may store, for example, an operation control program for operating the electronic book apparatus 2.

0018The e-book device 2 may always store the acquired e-book program in the storage unit 4, or stores the e-book program purchased or borrowed from a website or the like via a communication means in the storage unit 4. You may.

0019The display means 6 is an example of a means for displaying an electronic book page of an executed electronic book program. For example, one page or a plurality of pages are displayed, and an operation guide display and other functional information are displayed. In addition to displaying the currently displayed switching image from the first page (I) to the second page (II), the display means 6 displays the currently displayed page switching operation according to the page switching operation by the user, and also displays the second page. Only may be displayed.

0020The input means 8 is an example of the input operation detecting means of the present disclosure, and is installed on the display surface side of the display means 6 to detect the contact position and the contact state of the biological part 10 of the user. The input means 8 is formed of, for example, a touch panel combined with the display means 6, and is associated with the display content of the electronic book image displayed on the display means 6. That is, in the electronic book device 2, the input operation is performed when the contact position of the biological part 10 with respect to the input means 8 and the display position of the operation portion included in the electronic book image match.

0021The biological part 10 includes, for example, the fingers and palms of the user of the electronic book apparatus 2, and other parts of the body. In the electronic book device 2, a so-called swipe operation is performed as a slide operation in which the biological part 10 is brought into contact with the electronic book page image displayed on the display means 6 and the page is to be fed in the contacted state. And flick operations are performed. The slide operation includes, for example, a case where the user touches one finger, a case where two or more fingers are touched at the same time, or a case where the palm is touched with the input means 8. In the electronic book apparatus 2, the switching process from the first page to the second page is executed based on the contact position, the slide direction, and the slide amount of the biological part 10.

0022The vibrating means 12 is an example of means for vibrating the display surface of the display means 6 and the housing of the electronic book device 2, and is the timing of displaying an image on the display means 6 and the timing of contact of the biological part 10 with the input means 8. It vibrates at the timing of slide operation.

0023The control unit 14 is an example of means for performing operation control such as display processing of an electronic book page and page switching processing according to a user's input operation to the input means 8. Further, the control unit 14 controls the vibration generation by the vibration means 12 in, for example, in the display processing of the electronic book page, and gives the user a sense of operation.

0024In the electronic book apparatus 2, for example, as shown in A of FIG. 2, in the switching operation of sending the display page to the display screen and switching to another page, the user's biological part 10 swipes on the input means 8. Let me do it. At this time, the control unit 14 monitors the contact position and the sliding direction of the biological part 10 detected by the input means 8. Specifically, the control unit 14 monitors the contact position and the operation locus from the position A where the biological part 10 first contacts to the position E where the slide operation is stopped or the biological part 10 is separated from the input means 8. There is. The control unit 14 slides the positions A, B, C, D, and E with respect to the contact position of the biological part 10 detected by the input means 8 based on the coordinates set on the display screen 16. And the amount of displacement may be grasped.

0025Then, the electronic device 2 creates a vibration intensity setting table 18 for the detected contact position as shown in B of FIG. 2, and the vibration intensity P is set for the contact position of each biological part 10. At this time, the vibration intensity P is, for example, the strongest vibration at the first contact position A, changed so as to gradually attenuate the vibration intensity according to the slide operation, and the weakest at the contact position E where the page switching operation is completed. Is set to be.

0026This electronic book device 2 gives the user a feeling of turning a book page by giving such a vibration change. That is, at the beginning of turning a page, for example, the contact area with the next page to be switched (page II) is large with respect to the page to be switched (page I), and the resistance force at the time of slide operation is expressed by the strength of vibration strength. To do.

0027&lt;About display processing&gt;

0028FIG. 3 shows an example of the display processing of the electronic book apparatus. The processing content and processing procedure shown in FIG. 3 are examples, and the present disclosure is not limited to such content.

0029This display process is an example of the electronic book program of the present disclosure, and includes an operation detection process for the input means 8, a page switching display process, a vibration process for the operation, and the like.

0030For example, the electronic book device 2 executes an electronic book program stored in the storage unit 4 in response to a user's selection operation, and displays the electronic book page on the display means 6 (S1). The control unit 14 detects the contact of the biological part 10 with the display surface of the display means 6 based on the detection information from the input means 8 (S2). The control unit 14 records, for example, the acquired contact position information in the storage unit 4 as an initial position (S3). At this time, the storage unit 4 is formed with, for example, a vibration intensity setting table 18 including information on the contact position.

0031The electronic book device 2 vibrates the vibrating means 12 with the maximum intensity at the detection timing of the initial position (S4). For example, a plurality of vibration means 12 may be arranged in the electronic book apparatus 2. Then, the electronic book apparatus 2 may vibrate, for example, all the installed vibrating means 12 with the maximum intensity, or may vibrate the vibrating means 12 arranged at a position close to the initial position.

0032The input means 8 continues to detect the contact operation of the biological part 10, acquires the operation direction and the contact position information from the initial position (S5), and notifies the control unit 14. This contact position information may be recorded in, for example, the vibration intensity setting table 18 generated in the storage unit 4.

0033In the electronic book apparatus 2, the vibration intensity is set by the control unit 14 according to the change in the contact position of the biological part 10 with respect to the input means 8, and the vibration means 12 is vibrated based on this vibration intensity (S6). When the user of the electronic book 2 performs a slide operation to switch pages, the vibration becomes weak as the page switching progresses, and the user feels the feeling of turning pages.

0034According to such a configuration, since the user is directly given the feeling of turning the page, the operability of page switching can be improved. Since the user is made to grasp the correctness of the page turning by the operation feeling on the touch panel, the confirmation work such as the number of displayed pages can be reduced, and the user's continuation of reading is not hindered. In addition, by changing the vibration according to the slide operation, the user can intuitively grasp the state and suitability of page switching, and unnecessary redoing operations can be avoided.

0035[Second Embodiment]

0036FIG. 4 is a diagram showing an example of the electronic book apparatus according to the second embodiment.

0037The display device 20 is an example of the electronic book device of the present disclosure. For example, the display device 20 has a display function for displaying an electronic book page, an input operation function for switching pages by a contact operation with respect to the screen, and a vibration function for vibrating in response to the contact operation. Be prepared. The display device 20 is formed by a computer having control functions such as execution of an electronic book program, display control, and vibration control.

0038The display device 20 is formed with a housing 22 arranged around the side surface or the back side of the front surface on which the display surface is arranged. In addition to accommodating functional parts that form a computer inside the housing 22, the display surface of the monitor 24 is exposed to the outside of the housing 22 and arranged. A touch panel sensor 26 is installed on the display surface of the monitor 24. The touch panel sensor 26 may be formed so that the installation height of the exposed surface from the housing 22 is equal to the height of the side surface portion of the housing 22.

0039The monitor 24 is formed of, for example, an LCD (Liquid Crystal Display) unit or an organic EL (Electro Luminescence) display unit, and displays a generated electronic book page. The touch panel sensor 26 is an example of the input operation detecting means of the present disclosure, and enables contact input by detecting a change in capacitance or a magnitude of contact pressure with respect to contact with a user's finger or the like. This is an example of means.

0040The display device 20 includes a vibrating element 28 inside the housing 22. The vibrating element 28 is an example of the vibrating means of the present disclosure, and includes an element that vibrates by the rotational force of a drive motor (not shown) and an element itself that vibrates by applying a voltage. The vibrating element 28 is in contact with the back surface of the monitor 24 or a part of the housing 22 around the monitor 24, for example, inside the housing 22, and vibrates the monitor 24 and the housing 22 by driving the motor or oscillating the element itself. Let me. A plurality of vibrating elements 28 are installed inside the housing 22 at predetermined intervals, or they are formed as a single unit or a fixed length, and one vibrating element 28 is installed according to each side of the housing 22. You may. Motors and circuits may be formed independently of the vibrating elements 28 and may be vibrated independently, or a plurality of vibrating elements 28 may be connected to each other or all of them may be connected by a single motor or circuit.

0041&lt;About the display status of the e-book page&gt;

0042On the monitor 24, for example, as shown in FIG. 5, an electronic book page 30 including characters, photographs, icons, and other display contents is displayed. The e-book page 30 is displayed in the entire displayable area of the monitor 24 or in a set size. A boundary line 31 is set on the touch panel sensor 26 according to the peripheral edge of the display range of the electronic book page 30 displayed on the monitor 24.

0043The boundary line 31 sets a range for ending the vibration operation linked to the slide operation by the user's finger or the like in the page switching operation of the electronic book. Then, in the display device 20, when the user's finger or the like touches the specific position M1 of the electronic book page 30 and the slide operation is started, the finger comes out of the range delimited by the boundary line 31. Stop the vibration operation. The slide operation is managed by the touch panel sensor 26 based on the coordinate information set on the display range.

0044In the slide operation for the e-book page 30, the position M1 where the finger or the like first contacts is set as the reference position, the vibration intensity when the finger or the like first contacts is set as the reference position, and the vibration intensity when the finger or the like first contacts is set to the maximum. Attenuate. Further, in the page switching process, the slide amount and the slide position in the direction set for the electronic book are monitored with respect to the position M1, and the mode shifts to the mode in which the electronic book page 30 can be switched to the next page. For this slide position, for example, a boundary line 31 in a specific direction with respect to the position M1 may be set.

0045The boundary line 31 is set based on the size of the electronic book page 30 regardless of the display content and display direction of the electronic book page 30. That is, the boundary line 31 is not limited to the case of an electronic book page in which the displayed contents are displayed one page at a time in portrait orientation, and the electronic book is not limited to the case where the display content is displayed horizontally or two double-page spreads are displayed. Set by the size of page 30.

0046&lt;About page switching operation&gt;

0047As shown in FIG. 6, for example, the display device 20 is set with a reference axis LX that divides the touch panel sensor 26 in the vertical direction or a reference axis LY that divides the touch panel sensor 26 in the horizontal direction. The reference axes LX and LY may be set in vertical and horizontal directions based on, for example, the display direction set on the monitor 24, that is, the direction in which the electronic book page 30 is displayed. As a result, when the monitor 24 is tilted from the vertically long direction to the horizontally long direction, the display device 20 switches the display content of the electronic book page 30 from the vertically long direction to the horizontally long direction, and at the same time, the reference axis LX parallel to the long side direction and the short side. The reference axis LY may be set parallel to the side direction. The reference axes LX and LY are examples of criteria for determining whether or not to shift to a page switchable state for a slide operation such as a finger.

0048In the touch panel sensor 26, for example, the operation detection areas [R1] to [R4] are set by the reference axes LX and LY. In the page switching operation of the display device 20, the page switching process is performed based on the position M1 at which the finger first touches. That is, when the display device 20 reaches an area different from the area of contact at the start of the slide operation, the display device 20 shifts the page of the electronic book to a switchable state. The display device 20 grasps the operation detection area including the position M1 and monitors the slide operation.

0049For example, the display device 20 refers to the position M1 or the finger with respect to the area [R1] including the position M1 in which the finger touches and the area [R2] included in the same page with respect to the first electronic book page 30 before switching. The switching page 32 is generated and displayed according to the contact position. The switching page 32 is an example of a page operation screen that visually shows the state of turning the page according to the position of the slide operation, and is an example of the display content of the first electronic book page 30 and the second page 34 after switching. The displayed contents are included. On the switching page 32, the display ratio of the first page 30 and the second page 34 is set according to the slide position of the finger. The display device 20 is set so that the page is not switched by the slide operation in the area where the finger first touches.

0050The area for displaying the switching page 32 is set according to the page switching direction of the electronic book program and the division state by the reference axes LX and LY. Therefore, the switching page 32 is displayed in an area other than the area [R2] together with the area [R1], for example, when the electronic book page is slid in the vertical direction and the contact position M1 is in the area [R1]. Will be done.

0051Further, the display device 20 vibrates the vibrating element 28 in conjunction with the switching operation of the electronic book page. The display device 20 sets the maximum vibration intensity by the vibration element 28 when it comes into contact with the position M1, and attenuates the vibration intensity according to the slide operation. That is, the display device 20 changes the vibration frequency of the vibrating element 28 and the like according to the display ratio of the first electronic book page 30 and the second page 34 on the switching page 32 generated by the slide operation, and the vibration intensity. To set.

0052The display device 20 straddles the reference axis LX or LY by the slide operation, the finger is first region or in contact by detecting that reached al another operation detection region, shifting to a state capable of switching the page. The display device 20 that has transitioned to the page switchable state switches the display content from the switching page 32 to the second page 34 when the user releases the finger from the touch panel sensor 26. To switch the display contents, for example, the switching page 32 and the second page 34 may be exchanged, or the switching page 32 that gradually increases the display ratio of the second page 34 is continuously generated. May be good.

0053&lt;Slide operation to return to the original position&gt;

0054As shown in FIG. 7, the display device 20 is a mode that can be switched when the finger passes through another region from the position M1 and slides on the locus S to return to the position M1 on the touch panel sensor 26, for example. To cancel. Then, when the finger moves away from the touch panel sensor 26 at the position M1, the display device 20 switches the display content from the switching page 32 to the first electronic book page 30.

0055At this time, the vibrating element 28 vibrates at the maximum vibration intensity at the position M1, for example, and after the vibration intensity is attenuated according to the displacement on the locus S with respect to the region [R2] and the region [R4], the region [R4] to the region [R4]. The vibration intensity is increased again toward the region [R1] via R3]. The vibration intensity may be set based on the coordinates on the reference axes LX and LY, for example.

0056&lt;About other display examples of e-book pages&gt;

0057As shown in FIG. 8, for example, the display device 20 displays an electronic book page by page on the monitor 24, and page switching processing is performed according to a switching operation for this page. For example, as described above, the display device 20 has two reference axes LX and LY set in the vertical and horizontal directions with respect to the central portion of the touch panel sensor 26.

0058The display device 20 sets the contact position of the user detected by the touch panel sensor 26 as M1 and starts vibration at the maximum intensity. In this e-book program, for example, as a switching direction of the e-book page, a direction straddling the reference axis LY from the area [R1] or the area [R2] side is set.

0059After the display device 20 comes into contact with the area [R1] or the area [R2] of the first electronic book page 30 with respect to the divided touch panel sensor 26, the display device 20 straddles the reference axis LY by a slide operation, and the area [R3]. When the position M2 is reached, the page can be switched. At this time, the vibrating element 28 attenuates the vibration intensity according to the slide operation amount and the position from the position M1 (not shown).

0060When the contact position M2 is detected in the area [R3] of the display device 20, a part of the switching page 32 is arranged according to this position M2, and the first electronic book page is arranged in the left-right direction based on the position. Generate switching page 32 with the display ratio of 30 and the second page 34 set.

0061Further, as shown in FIG. 9, for example, the display device 20 continuously reappears even when the user's finger straddles the reference axes LY and LX from the position M1 by a slide operation and reaches another area. When returning to the area [R1], the switchable state of the page is canceled. At this time, if the position where the user returns his / her finger is different from the initial position M1, the vibration element 28 may have different vibration intensities depending on, for example, the distance from the position M1. Specifically, the vibration intensity of the vibrating element 28 increases in the direction in which the value of the reference axis LX or the reference axis LY of the electronic book program decreases. Then, when the region [R1] is reached, the vibration intensity is attenuated from the maximum value by the amount separated from the position M1.

0062The switching direction of the display device 20 may be set in a direction straddling the reference axis LX from the area [R1] or the area [R3]. Further, the display device 20 is not limited to the case where both the reference axes LX and LY are set. The display device 20 may set only one of the reference axes LX and LY, for example, depending on the display content of the displayed electronic book page and the direction of the page switching operation set in the electronic book program.

0063&lt;Processing for page switching operation&gt;

0064FIG. 10 shows an example of processing for the page switching operation.

0065The display device 20 monitors the input processing of page switching by detecting contact with oil parts by the touch panel sensor 26 (S11), and when the user's finger touches, the page is turned to the user who performs the page switching operation. In order to give a feeling, vibration control processing is performed in conjunction with the slide operation (S12). In this vibration control process, for example, finger contact position information by the touch panel sensor 26 and operating force information by the pressure sensor 40 are taken into the control unit 42, and the vibration intensity by the vibration element 28 and the like are set. Further, in the vibration control process, for example, the power supply unit 44 controls the amount of power supplied as a means for adjusting the vibration intensity of the vibration means.

0066Then, in the display unit including the monitor 24, the electronic book page 30 is subjected to the display process of the switching page 32 and the vibration process of vibrating the vibrating element 28 in response to the slide operation (S13). &lt;About the configuration example of the control unit&gt;

0074&lt;About e-book display processing&gt;

0075FIG. 12 is a flowchart showing an example of display processing of an electronic book. This display process is an example of the electronic book program of the present disclosure.

0076When the display device 20 executes the selected e-book program (S31), the display device 20 displays a specific e-book page 30 on the monitor 24 (S32). The control unit 42 monitors the detection information of the touch panel sensor 26 and determines whether or not the contact by the user's finger is recognized (S33). When finger contact is detected (YES in S33), it is determined whether the contact position can be read (S34), and the first contact position M1 is specified. This contact state monitoring is repeated until the contact position M1 can be identified (NO in S34).

0077When the contact position M1 is specified (YES in S34), the control unit 42 shifts to vibration processing by the vibration element 28 and vibration control for changing the vibration intensity (S35). Further, the control unit 42 generates the switching page 32 as a display of an image showing the page turning state according to the detected finger contact position (S36).

0078The control unit 42 determines whether or not the finger contact position continuously exceeds the reference axis LX or LY and the slide operation is continuously performed as the determination of the transition to the page switchable state (S37). .. When it is determined from the finger contact monitoring result that the reference axis has been exceeded (YES in S37), the control unit 42 performs vibration control so as to change the damping amount of the vibration intensity as the vibration processing (S38). In this vibration control, for example, by changing the vibration state in the area including the initial position M1 and the area operated beyond the reference axis, the user is made to know that the page can be switched. ..

0079The control unit 42 determines whether the finger is released from the touch panel sensor 26 by monitoring the contact of the finger, or whether the finger is returned to the initial region by continuous operation (S39). When the user releases the finger from the touch panel sensor 26 (released in S39), the switchable state is entered, so the control unit 42 switches the display page and monitors the second page 34 24. (S40). Based on the detection result of the touch panel sensor 26, the control unit 42 stops the vibration of the vibrating element 28 by the stop control for the vibrating component 60 and the power supply control for the power supply unit 44 when the contact of the user is released.

0080When the user is performing the slide operation in a region other than the current region or the initial region without releasing the finger (Do not release, do not return in S39), the control unit 42 is based on the vibration condition of the region in contact. Vibration control is executed (S41), and finger contact is continuously monitored.

0081In addition, when the user's finger returns to the initial region (returned in S39), the control unit 42 continuously monitors the finger contact state.

0082If the control unit 42 determines that the user's finger is sliding without crossing the reference axis (NO in S37), the control unit 42 performs vibration control according to the distance from the initial position M1 (S42), and then the finger. Monitor the contact status of (S43). Then, when the finger is separated from the touch panel sensor 26 (YES in S43), the switching page 32 indicating the turning state is erased, the original first electronic book page 30 is displayed (S44), and the vibration is terminated (S44). S45).

0083When the finger slides without being separated (NO in S43), the control unit 42 continuously monitors the finger contact.

0084&lt;About setting the vibration intensity according to the slide operation of the finger&gt;

The values of the vibration intensity, the contact position coordinates, and the change states of the vibration intensity shown in FIGS. 13 to 18 are examples, and the change states of the vibration intensity are not limited to the contents shown in the drawings.

0086In this vibration intensity setting process, the maximum vibration intensity is set at the first contact position M1, and the vibration intensity is calculated based only on the position in the X direction with reference to this position M1. Further, the control unit 42 shifts to the page switchable state with the reference axis LY as a boundary. The arrows in the figure indicate the detection order in the X direction among the detection information by the touch panel sensor 26. Further, in this vibration intensity setting, the case where the first contact is made in the area [R1] on the touch panel sensor 26 divided by the reference axes LX and LY is shown.

0087&lt;Vibration control example 1&gt;

0088When the control unit 42 detects the coordinates (X1, Y1) as the first contact position as shown in FIG. 13, for example, the control unit 42 sets the vibration intensity at this position to the initial vibration intensity Fs which is the maximum value. In finger contact monitoring, for example, the touch panel sensor 26 detects contact coordinates at intervals of t for a certain period of time. In the vibration intensity setting process, the position coordinates in the X direction and the slide direction of the finger are used among the position coordinates acquired in the finger contact monitoring.

0089When the control unit 42 acquires the coordinates (X2, Y2) detected after the lapse of time t, it determines the change direction in the X direction and determines whether the displacement is in the reference axis LY direction for shifting to page switching. .. Then, the vibration intensity F at the position X2 is calculated based on, for example, the following equation (1). Here, assuming that the coordinates of the reference axis LY in the X direction are Xk, the vibration intensity F when (X2 Xk) is F = Fs-a × | X2-X1 | (1) Will be. A in Eq. (1) is a constant indicating the slope of the change in vibration intensity in the region [R1].

0090The vibration intensity F when the contact position is in the region [R1], that is, when the coordinates in the X direction are (X Xk), is calculated by using the following equation (2). F = Fs-a × | X-X1 | (2) The control unit 42 attenuates the vibration intensity in proportion to the amount of change in the contact position of the finger due to the slide operation from the initial contact position. In this vibration intensity setting process, the vibration intensity F is integrated using Eq. (2) every t hours.

0091The vibration intensity Fk when the finger overlaps the reference axis LY by the slide operation, that is, when X = Xk, is calculated by Eq. (2). Fk = Fs-a × | Xk-X1 | (3) The control unit 42 holds the calculated Fk value in, for example, the memory 52.

0092When a finger straddles the reference axis LY and enters the region [R3] from the region [R1] and Xk &lt;X, the vibration intensity F at the position X in this region is the amount of change from the reference axis LY. Is proportional to. F = Fk-b × | X-Xk | (4) Will be. B in this equation (4) is, for example, a constant indicating the slope of the change in vibration intensity in the region [R3].

0093In this vibration intensity setting, a &lt;b is set in the region [R3] than in the region [R1] because the change in the vibration intensity due to the slide of the finger is larger.

When is performed, the control unit 42 uses the equation (4).

0095When the user reaches the area [R3] side in the page switching operation but does not release the finger and slides the control unit 42 in the opposite direction through the original path, the slide operation is performed. The vibration intensity is set according to the direction and contact position of. That is, when the position Xn is the maximum position in the X direction and the slide direction of the next position X (n + 1) is opposite to the slide direction from the position X1 to the position X2, depending on the area where the finger touches. , Eq. (2) or Eq. (4) is used to calculate the vibration intensity F.

F = e × 1 / [(| X-Xk |)^c+ d] (5) C, d, and e in this equation (5) are constants. Of these, d is a value that retains the vibration intensity at the position (Xk) on the reference axis LY. According to Eq. (5), when the slide operation exceeds the reference axis LY, the control unit 42 is in a state where the page can be switched by suddenly changing the vibration intensity F with respect to the change of the finger in the X direction. Communicate this to the user sensuously.

0101In the vibration intensity calculation process of position Xn, the slide direction of the finger from the previous detection position X (n-1) to position Xn is the same as the slide direction from position X1 to X2, and the page switching operation is performed in a fixed direction. When is performed, the control unit 42 uses the equation (5).

The vibration intensity is set according to the direction and contact position of. That is, when the slide in the X direction from position Xn to position X (n + 1) is opposite to the slide direction from position X1 to position X2, Eq. (2) or Eq.

0104When the control unit 42 detects the coordinates (X1, Y1) as the first contact position as shown in FIG. 15, for example, the control unit 42 sets the vibration intensity at this position to the initial vibration intensity Fs which is the maximum value. When the control unit 42 acquires the coordinates (X2, Y2) detected after the lapse of time t, it determines the change direction in the X direction and determines whether the displacement is in the reference axis LY direction for shifting to page switching. To do. Then, the vibration intensity at the position X2 is calculated based on, for example, Eq. (1).

When is performed, the control unit 42 uses the equation (4).

0109In the page switching operation of the user, the control unit 42 reaches the area [R3] side, but when the slide operation is performed in the opposite direction through the original path without releasing the finger, the slide operation is performed. The vibration intensity is set according to the direction and contact position of. In this page switching process, the vibration intensity F is attenuated even when the display of the switching page 32 is returned to the display of the first electronic book page 30.

0110In the slide operation from the position Xn of the region [R3] to the position X (n + 1) of the region [R1], the vibration intensity F is set by the following equation (6). F = Fn-f × | X (n + 1) -X (n) | (6) F in Eq. (6) is a constant indicating the slope of the change in vibration intensity with respect to the change in the X direction.

The vibration intensity F is newly attenuated toward the position X (n + 1). For example, when the slide operation from position Xn to position X (n + 1) is opposite to the slide direction from position X1 to position X2, the control unit 42 refers to the reference vibration intensity F ( l) is set. This reference vibration intensity F (l) is an example of the initial vibration intensity for the operation of returning the page, and a value smaller than at least the initial vibration intensity Fs is set.

The value of the vibration intensity F (k2) of the reference axis is different from that in the case of the slide operation of page switching, but it is not limited to this. The slope g of Eq. (8) may be set so that Fk and F (k2) have the same value.

0121Then, the control unit 42 calculates the vibration intensity when the slide operation reaches the position [R1] from the position Xk of the reference axis LY by the following equation (10). F = F (k2) -h × | X-Xk | (10) Here, h is a constant indicating the slope of the change in vibration intensity from the position Xk to the position X.

The vibration intensity F may be set.

0129&lt;About a modified example of page switching operation&gt;

0130The display device 20 can switch a plurality of pages with one operation, for example, in a page switching operation of an electronic book.

0131As shown in FIG. 19, for example, when a display image 70 indicating that there are a plurality of pages on the screen is displayed, the display device 20 turns the plurality of pages in a single operation. In the page switching operation, the control unit 20 includes, for example, a touch panel sensor 26 and a pressure sensor 40 inside the housing 22. Then, in the finger monitoring process, the control unit 42 sets the number of switching pages according to the load due to the operating force, for example, based on the detection result of the pressure sensor 40. That is, in the display device 20, when the operating force for pressing the monitor 24 is larger than that when switching one page, the number of page switching is determined by the ratio of the load.

0132The monitor 24 displays a multi-layer switching page indicating that a plurality of sheets have been turned by the display process of the control unit 42. The display device 20 sets the initial vibration intensity Fs based on the pressing pressure information acquired by the pressure sensor 40 in the finger monitoring process. In the display device 20, for example, the maximum value of the initial vibration intensity Fs is changed according to the number of pages to be switched by one operation.

0133When the number of operations is set by the strength of the pressing, the control unit 42 sets the initial vibration intensity Fs based on the vibration intensity ratio of the vibration intensity setting table 80, which is the first operation table, as shown in FIG. 20, for example. To do. In this vibration control, when turning a large number of sheets at once, the strength of the slide operation is changed according to the weight of the switching page 32 according to the number of sheets, and the user feels the operation state and the resistance when turning the paper. Give to. The initial vibration intensity Fs is calculated according to a set ratio with respect to, for example, the maximum vibration intensity that can be vibrated by the vibration element 28 and the magnitude of the electric power supplied to the vibration element 28.

0134According to such a configuration, the display device 20 can sensuously recognize the page switching state by changing the operation feeling for the user according to the page switching state by the slide operation on the touch panel sensor 26. .. In addition, the display device 20 gives the user such a feeling of operation to determine whether the page can be switched, whether the finger can be released, and whether it is possible to return to the page read immediately before with less work. You can judge. That is, by giving the user a sense of operation by changing the vibration, it is possible to grasp that an appropriate operation has been performed or that the operation has not been performed properly.

0135[Third Embodiment]

0136FIG. 21 shows an example of usage history information used in the electronic book apparatus according to the third embodiment.

0137In the display device 20 according to this embodiment, for example, as shown in FIG. 21, the usage history table 82 of the electronic book program is stored in the database 54. The usage history table 82 is an example of the usage history information of the present disclosure. The display device 20 changes the feeling of resistance in the page switching operation, for example, for a book that is frequently used. That is, if the book is familiar to the user, the user is accustomed to the flipping operation by sliding the touch panel. Further, in the case where the book is paper, for example, the display device 20 reduces the resistance friction between the pages due to the deposits on the surface of the pages and the wrinkles of the pages. The vibration intensity is changed depending on the number of times of use.

0138When the display device 20 starts, for example, the electronic book program, the display device 20 stores the count value of the counter function (not shown) in the usage history table 82 in association with the electronic book data 30. For example, when the electronic book data used more than a predetermined value is activated, the display device 20 uses the vibration intensity setting table 84 as the second operation table shown in FIG. 22 instead of the vibration intensity setting table 80 described above. Use. In this vibration intensity setting table 84, for example, the vibration intensity ratio is set for each number of pages to be switched at one time. The initial vibration intensity Fs set in the vibration intensity setting table 84 is reduced to half that of, for example, the vibration intensity setting table 80.

0139&lt;About e-book display processing&gt;

0141When the electronic book application is started on the display device 20 (S51), it is determined whether or not the number of times the electronic book application is started is less than a predetermined number (S52). The usage history table 82 may be used to determine the number of times of use. If the number of uses is less than the specified number (YES in S52), the control unit 42 determines that the user is not accustomed to reading this e-book, and initially starts based on the vibration intensity setting table 80, which is the first table. The vibration intensity Fs is read out and the electronic book page 30 is displayed (S53).

It may be processed in the same manner as S33, S34, 36, and S37, and detailed description thereof will be omitted.

0143In the positive vibration control, the vibration intensity setting table 80 (Table 1) is referred to, and the vibration control including the setting of the initial vibration intensity Fs according to the number of pages to be slid is performed (S58). In addition, the control unit 42 shifts to the page switching mode when the reference axis LX or LY is exceeded according to the contact position monitoring result (S59).

0144The control unit 42 determines whether the user has released the finger from the touch panel sensor 26 or returned to the initial region (origin) by continuous operation by monitoring the slide operation of the user (S60). When the user releases the finger from the touch panel sensor 26 (released in S60), the control unit 42 switches the display page and displays the second page 34 on the monitor 24 (S61).

0145When the user is performing the slide operation in a region other than the current region or the initial region without releasing the finger (Do not release, do not return in S60), the control unit 42 is based on the vibration condition of the region in contact. Vibration control is performed (S62), and finger contact monitoring is continuously performed.

0146In addition, the control unit 42 continuously monitors the finger contact state when the user's finger returns to the initial region (returned in S60).

0147If the control unit 42 determines that the user's finger is sliding without crossing the reference axis (NO in S57), the control unit 42 performs vibration control according to the distance from the initial position M1 (S63), and then the finger. Monitor the contact status of (S64). Then, when the finger is separated from the touch panel sensor 26 (YES in S64), the switching page 34 indicating the turning state is erased, the original electronic book page 30 is displayed (S65), and the vibration is terminated (S66).

0148If the control unit 42 determines that the number of times the e-book program has been used is equal to or greater than the predetermined number (NO in S52), the control unit 42 determines that the user is accustomed to reading this e-book, and the vibration intensity, which is the second table. The initial vibration intensity Fs is read out based on the setting table 84, and the electronic book page 30 is displayed (S71). The processes S72 to S84 including the finger contact monitoring and the vibration process may be performed in the same manner as the above-described processes S54 to S66, and detailed description thereof will be omitted.

0149According to such a configuration, the vibration intensity according to the frequency of use of the e-book program gives the user the feeling that the page is turned over and over and the book is made of used paper. , It is possible to reduce the feeling of contact discomfort caused by sliding to the touch panel. In addition, by giving an operation feeling similar to the feeling of turning a paper book, the user can be accustomed to the slide operation on the touch panel. In addition, by intuitively grasping the operation state of the touch panel, it has shifted to a state where page switching is possible, and since the correctness of the page switching operation is grasped by the touch feeling, it is possible to visually check the displayed contents. Eliminate and improve convenience.
