Mode for Carrying Out the Invention

Examples

[0012] An information display device according to Example 1 of the present invention will be described. In the following description, a case where the information display device has a function as a route search device that searches for a route from a current location to a destination will be described.

[0013] FIG. 1 shows the vicinity of the front seat of the automobile M. As shown in FIG. 1, the information display device 10 is mounted on the automobile M. Note that the automobile M is an example of a moving body. The moving body may be a moving body other than an automobile, such as a bicycle, a motorcycle, an airplane, a ship, or a portable terminal possessed by a moving person.

[0014] The information display device 10 is, for example, a device mounted inside the dashboard DS of the automobile M. The information display device 10 causes the touch panel 20 provided on the dashboard DS of the automobile M to display map information, route guidance information, and the like.

[0015] The touch panel 20 has, for example, a screen 20a as a display screen formed in a rectangular shape. The touch panel 20 is a display input device having a display function for displaying to the user and an input function for receiving an input operation from the user. For example, a liquid crystal touch panel or the like is used for the touch panel 20.

[0016] The touch panel 20 has a NUI (Natural User Interface) which is an interface that receives touch operations such as taps and swipes performed by a user's finger.

[0017] Note that a tap is a touch operation in which the user's fingertip taps the screen 20a of the touch panel 20 once. A swipe is a touch operation in which the user's finger touches the screen 20a of the touch panel 20 and the fingertip is slid on the screen 20a. Here, the touch operation will be described as an operation by the user from when the user's finger touches the screen 20a of the touch panel 20 until the user's finger leaves the screen. Also, the touch operation will be described as a single touch operation that changes the display mode of the screen 20a of the touch panel 20.

[0018] Here, the proximal side of the touch panel 20 as viewed from the windshield FG of the vehicle M is described as the upper side of the screen 20a of the touch panel 20, and the distal side of the touch panel 20 as viewed from the windshield FG of the vehicle M is described as the lower side of the screen 20a of the touch panel 20. Also, in FIG. 1, the driver's seat side is described as the right side of the screen 20a of the touch panel 20, and the passenger seat side is described as the left side of the screen 20a of the touch panel 20.

[0019] FIG. 2 shows the functional blocks of the information display device 10. As shown in FIG. 2, in the information display device 10, each of the input / output unit 11, the communication unit 12, the storage unit 13, and the control unit 14 are connected to each other via a system bus 15.

[0020] As described above, the touch panel 20 displays maps, route guidance information, etc. on its screen 20a. The input / output unit 11 is an interface unit connected to the touch panel 20. Therefore, the information display device 10 can display information on the screen 20a of the touch panel 20 via the input / output unit 11. Also, the information display device 10 can receive input information input to the screen 20a of the touch panel 20 via the input / output unit 11.

[0021] The communication unit 12 is an interface unit for connecting to external devices (not shown) such as server devices via a network (not shown) such as the Internet. The information display device 10 is connected to be capable of data communication with the server device via the communication unit 12. For example, the information display device 10 can request the server device to transmit data held by the server device to itself and receive the requested data.

[0022] The storage unit 13 is constituted by, for example, a hard disk device, an SSD (Solid State Drive), a flash memory, etc. The storage unit 13 stores various programs such as BIOS (Basic Input Output System), OS (Operation System), and application software.

[0023] The storage unit 13 holds the application program 13A as content and the application program 13B as content. Further, the storage unit 13 holds a map DB (Data base) 13C that stores map information of the road on which the vehicle M travels.

[0024] The application program 13A is a program that can play AV (Audio Visual) such as videos and music distributed by, for example, streaming.

[0025] The application program 13B is a program that can display, for example, messages of SNS (Social Network Service) typified by an instant messenger on the screen.

[0026] Note that these application programs 13A and 13B are examples, and the application programs stored in the storage unit 13 may be changed as appropriate. For example, an application program that can display the congestion status of a parking lot in real time may be stored in the storage unit 13.

[0027] The control unit 14 is realized by a computer having a CPU (Central Processing Unit) 14a as an arithmetic processing device, a ROM (Read Only Memory) 14b as a main storage device, and a RAM (Random Access Memory) 14c. The CPU 14a reads a program corresponding to the processing content from the ROM 14b or the storage unit 13, expands it in the RAM 14c, and realizes various functions in cooperation with the expanded program.

[0028] The control unit 14 can read map information from the map DB 13C in the storage unit 13 and display a map image on the screen 20a of the touch panel 20 based on the map information. Further, the control unit 14 can generate route information to the destination input from the touch panel 20 and display the generated route information on the screen 20a of the touch panel 20.

[0029] The control unit 14 can execute the application program 13A and the application program 13B from the storage unit 13 to generate a plurality of content images. In other words, each of the plurality of content images is generated by executing each of the plurality of application programs 13A and 13B.

[0030] The control unit 14 can receive a touch operation of the user on the screen 20a of the touch panel 20. Therefore, the control unit 14 functions as an input operation reception unit that receives a touch operation (first input operation) for enlarging or reducing the content display area, which is the first display area of the screen 20a.

[0031] In addition, the control unit 14 can detect that the user's finger has touched the screen 20a of the touch panel 20 and that the finger has left the screen 20a of the touch panel 20 based on, for example, an input signal from the touch panel 20. Further, the control unit 14 can detect the slide direction of the touch operation by the user based on, for example, an input signal from the touch panel 20.

[0032] The control unit 14 can simultaneously display the above-described map image and a plurality of content images on the screen 20a. Specifically, it is possible to display on the screen 20a of the touch panel 20 a display including a content display area for displaying a plurality of content images and a map display area for displaying the map image which is the second display area. Therefore, the control unit 14 functions as a first display control unit that selectively displays content images corresponding to a plurality of application programs in the content display area on the screen 20a. Also, the control unit 14 can enlarge or reduce the content display area within the screen 20a between a plurality of default sizes according to a touch operation by the user.

[0033] Based on a touch operation for enlarging or reducing the content display area of the screen 20a, the control unit 14 can perform a second display form process for changing the display form of the content image. Based on a touch operation for enlarging or reducing the content display area of the screen 20a, the control unit 14 can perform a third display form process for changing the display form of the map image. Therefore, the control unit 14 functions as a display form processing unit.

[0034] Figure 3 shows an example of the display mode of the screen 20a of the touch panel 20. In Figure 3, in addition to the touch panel 20, a finger PF of a user operating the touch panel 20 is shown. The arrow in the figure indicates the sliding direction of the user's finger PF.

[0035] As shown in Figure 3, on the left side of the screen 20a, there is arranged a content display area 16 for displaying content images generated by executing the application program 13A and the application program 13B. That is, the display shown on the screen 20a includes the content display area 16 as a first display area where a plurality of content images are displayed.

[0036] On the right side of the screen 20a, a map display area 17 is arranged as another display area adjacent to the content display area 16. That is, on the screen 20a, the content display area 16 is displayed on the left side with the boundary BO as the boundary, and the map display area 17 is displayed on the right side.

[0037] A map image is displayed in the map display area 17. Also, a route from the current location to the destination may be displayed in the map display area 17. Note that it is sufficient that the display including the content display area 16 is made on the screen 20a of the touch panel 20. For example, only the content display area 16 may be displayed.

[0038] In the content display area 16, two arranged display frames 16a and 16b are displayed. The two display frames 16a and 16b are arranged side by side vertically. That is, the two display frames 16a and 16b are arranged in a column from the upper side to the lower side of the screen 20a of the touch panel 20.

[0039] Content images different from each other may be displayed in the display frame 16a and the display frame 16b. For example, as in the example of FIG. 3, a content image generated by executing the application program 13A may be displayed in the upper display frame 16a. Also, a content image generated by executing the application program 13B may be displayed in the lower display frame 16b.

[0040] In the example of FIG. 3, the content display area 16 is displayed in the first default size. For example, in the case of the first default size, the content display area 16 has a width of W1 which is 1 / 3 of the width of the screen 20a. Note that the first default size can be freely set according to the embodiment.

[0041] In the information display device 10 of this embodiment, when a touch operation is performed on the touch panel 20 with the user's finger PF, the boundary BO moves in the left - right direction, and thus the size of the content display area 16 changes. Specifically, for example, in response to a swipe operation in the direction of the arrow in the figure, that is, a left - right swipe operation with the user's finger PF, the boundary BO moves in the left - right direction, and thus the size of the content display area 16 changes. The size of the content display area 16 changes sequentially following the movement of the finger PF in the swipe operation.

[0042] In addition, in the touch operation for changing the size of the content display area 16, the touch position of the user's finger PF may be on the boundary BO or at any position within the content display area 16.

[0043] In this embodiment, since the content display area 16 is on the left side of the screen 20a, for example, when the user performs a touch operation of swiping the finger PF to the right, the boundary BO moves to the right and the content display area 16 expands. Specifically, for example, when the user swipes the finger PF to the right so as to cross the boundary between the content display area 16 and the map display area 17, the content display area 16 is expanded.

[0044] Also, when the user performs a touch operation of swiping the finger PF to the left, the boundary BO moves to the left and the content display area 16 shrinks. Specifically, for example, when the user swipes the finger PF to the left so as to cross the boundary between the content display area 16 and the map display area 17, the content display area 16 is shrunk. That is, the touch operation in which the user swipes the finger PF in the left - right direction is the first input operation for expanding or shrinking the content display area.

[0045] The sizes of the two display frames 16a and 16b are enlarged or reduced in the horizontal direction of the screen 20a as the content display area 16 is enlarged or reduced. Also, the content images displayed in the two display frames 16a and 16b are enlarged or reduced in size as the display frames 16a and 16b are enlarged or reduced. Note that the display mode of the content images may be changed as the display frames 16a and 16b are enlarged or reduced. Also, the size of the map display area 17 is enlarged or reduced in the horizontal direction of the screen 20a as the content display area 16 is enlarged or reduced.

[0046] FIG. 4 shows an example of the display mode of the screen 20a of the touch panel 20. As shown in FIG. 4, the content display area 16 is displayed in a second default size that is larger than the first default size. For example, the content display area 16 in the second default size has a width of W2, which is half the width of the screen 20a. In the present embodiment, the second default size has a width of W2 from the left end of the screen 20a.

[0047] For example, the change in the display mode from the mode of FIG. 3 to the mode of FIG. 4, that is, the change in the content display area 16 from the first default size to the second default size, is caused by a swipe operation of the finger PF to the right. Also, the reverse change is caused by, for example, a swipe operation of the finger PF to the left.

[0048] FIG. 5 shows an example of the display mode of the screen 20a of the touch panel 20. In FIG. 5, a closed display in which the content display area 16 is not displayed on the screen 20a is shown. Therefore, only the map display area 17 is displayed on the screen 20a.

[0049] For example, the change in the display mode from the mode of FIG. 3 to the mode of FIG. 5, that is, the change in the content display area 16 from the first default size to the closed display, is caused by a swipe operation of the finger PF to the left. Also, the reverse change is caused by, for example, a swipe operation of the finger PF to the right.

[0050] The content display area 16 is displayed on the screen 20a of the touch panel 20 in three modes: the first default size shown in FIG. 3, the second default size shown in FIG. 4, and the closed display shown in FIG. 5, except during an operation by the finger PF. Similarly, the map display area 17 is also displayed on the screen 20a of the touch panel 20 in the three modes shown in FIGS. 3, 4, and 5.

[0051] That is, the content display area 16 is displayed in only three predetermined display modes, except during an operation by the finger PF. In other words, the boundary BO is in one of the three positions shown in FIGS. 3, 4, and 5, except during an operation by the finger PF.

[0052] Which default display mode the content display area 16 is displayed in is determined according to the size of the content display area 16 when the touch operation ends. In other words, after the touch operation ends, the boundary BO is brought to a predetermined position determined by the position of the boundary BO when the touch operation ends, whereby the content display area 16 is set to the default display mode.

[0053] An example of how the default display mode after the touch operation ends is determined will be described with reference to FIG. 6. FIG. 6 shows the state where the content display area 16 is of the first default size. Also shown in FIG. 6 are border lines BR1 and BR2 that serve as a reference for what default size the content display area 16 will be. In this example, the border line BR1 is at the position of the boundary BO when the content display area 16 is 110% of the first default size. Also, the border line BR2 is at the position of the boundary BO when the content display area 16 is 90% of the first default size.

[0054] As described above, the boundary BO moves by a touch operation (hereinafter referred to as a slide operation) of sliding the finger PF. In the information display device 10 of the present embodiment, at the end of the slide operation, that is, when the finger PF leaves the screen, the display mode of the content display area 16 is determined according to the position of the boundary BO with respect to the border lines BR1 and BR2.

[0055] For example, when the boundary BO is to the right of the border line BR1 at the end of the slide operation, the display mode of the content display area 16 is determined to be the second default size.

[0056] For example, when the boundary BO is between the border line BR1 and the border line BR2 at the end of the slide operation, the display mode of the content display area 16 is determined to be the first default size.

[0057] For example, when the boundary BO is to the left of the border line BR2 at the end of the slide operation, the display mode of the content display area 16 is determined to be a closed display.

[0058] In this way, the content display area 16 is enlarged or reduced during the slide operation, and the content display area 16 is changed to a default size according to the position of the boundary BO at the end of the slide operation. The change unit of the enlargement or reduction of the content display area 16 during this slide operation is smaller than the change unit between each of the default sizes.

[0059] As described above, by enlarging or reducing the content display area 16 based on the size of the content display area 16 when the user's touch operation ends, it is possible to display in a display mode that reflects the intention of the touch operation performed by the user.

[0060] FIG. 7 shows the information display process R1 by the information display device 10. As shown in FIG. 7, when the application program 13A and the application program 13B are executed, the control unit 14 starts each of the application program 13A and the application program 13B (step S101).

[0061] The control unit 14 causes the content images generated by the execution of each of the application program 13A and the application program 13B started in step S101 to be displayed on the display frames 16a and 16b. Further, the control unit 14 causes a map image to be displayed in the map display area 17. That is, the control unit 14 causes the display to be displayed on the screen 20a of the touch panel 20 (step S102). Therefore, the control unit 14 functions as a first display control unit that causes the display including the content display area 16 for displaying a plurality of contents to be displayed on the screen 20a.

[0062] When a touch operation of swiping by the user is performed in the content display area 16 of the screen 20a, the control unit 14 changes the size of the content image displayed in the content display area 16 (step S103). That is, the content display area 16 can be enlarged or reduced in accordance with the touch operation of the user.

[0063] Therefore, the control unit 14 functions as a display form processing unit that performs a second display form process for changing the display form of the content image based on a touch operation for enlarging or reducing the content display area of the screen 20a. Further, along with the enlargement or reduction of the content display area of the screen 20a, the map image is also enlarged or reduced. That is, the control unit 14 functions as a display form processing unit that performs a third display form process for changing the display form of the map image based on a touch operation for enlarging or reducing the content display area of the screen 20a.

[0064] The control unit 14 determines whether the engine of the vehicle M has stopped (step S104). If the control unit 14 determines in the determination of step S104 that the engine of the vehicle M has not stopped (step S104: N), it returns to the content image size change process of step S103.

[0065] If the control unit 14 determines in the determination of step S104 that the engine of the vehicle M has stopped (step S104: Y), it ends the display on the screen 20a (step S105) and ends each application program 13A and application program 13B (step S106).

[0066] FIG. 8 shows a subroutine R2 for changing the size of the content image in step S103. As shown in FIG. 8, the control unit 14 determines whether there has been a slide operation by the user (step S201). In the determination of step S201, the control unit 14 determines whether a touch operation for enlarging or reducing the content display area 16, that is, whether a slide operation has been performed in the left - right direction.

[0067] If the control unit 14 determines in the determination of step S201 that there has been no slide operation by the user (step S201: N), it ends the process.

[0068] If the control unit 14 determines in the determination of step S201 that there has been a slide operation by the user (step S201: Y), it accepts the slide operation. At this time, the control unit 14 enlarges or reduces the content display area 16 and the map display area 17 following the slide operation. In this way, the control unit 14 functions as an input operation reception unit that accepts touch operations performed on the screen 20a.

[0069] The control unit 14 determines whether or not the received slide operation has ended (step S202). For example, the control unit 14 determines that the slide operation has ended based on the fact that the user's finger PF has left the screen 20a. Incidentally, when the control unit 14 determines in the determination of step S202 that the received slide operation has not ended (step S202: N), the control unit 14 makes the determination of step S202 until the received slide operation ends.

[0070] When the control unit 14 determines in the determination of step S202 that the received slide operation has ended (step S202: Y), the expansion or contraction of the content display area 16 during the touch operation ends.

[0071] It is determined whether or not the position of the boundary BO at the end of the slide operation, that is, the position of the boundary BO on the last screen 20a of the touch operation, is to the right of the border line BR1 (step S203).

[0072] When the control unit 14 determines in step S203 that the position of the boundary BO is to the right of the border line BR1 (step S203: Y), the content display area 16 is set to the second default size (step S204). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0073] When the control unit 14 determines in step S203 that the position of the boundary BO is to the left of the border line BR1 (step S203: N), it is determined whether or not the position of the boundary BO at the end of the slide operation, that is, the position of the boundary BO on the last screen 20a of the touch operation, is to the left of the border line BR2 (step S205).

[0074] When the control unit 14 determines in step S205 that the position of the boundary BO is to the left of the border line BR2 (step S205: Y), it causes the content display area 16 to be closed (step S206). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0075] When the control unit 14 determines in step S205 that the position of the boundary BO is to the right of the border line BR2 (step S205: N), it sets the content display area 16 to the first default size (step S207). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0076] In this way, the control unit 14 sets the sizes of the content display area 16 and the map display area 17 to predetermined default sizes according to the position of the boundary BO when the slide operation for enlarging or reducing the content display area 16 ends, that is, according to the size of the content display area 16.

[0077] In addition, in this embodiment, it has been described that the content display area 16 is displayed on the screen 20a of the touch panel 20 in three display sizes: the first default size, the second default size, and the closed display. However, the content display area 16 is not limited to three display modes. For example, a default size may be provided between the first default size and the second default size to increase the display modes for implementation.

[0078] Also, in this embodiment, which default display mode the content display area 16 is displayed in is determined by the position of the boundary BO when the touch operation ends. However, which default display mode the content display area 16 is displayed in can be freely set. For example, according to the slide amount of the user's slide operation, it may be determined which default display mode the content display area 16 is displayed in.

[0079] As described above, when the content display area 16 is enlarged or reduced on the screen 20a of the touch panel 20, the information display device 10 according to the present embodiment enlarges or reduces the content display area 16 based on the size of the content display area 16 when the user's slide operation ends.

[0080] Therefore, by enlarging or reducing the content display area 16, it becomes possible to easily display the information desired by the user in an appropriate size. In particular, when the information display device 10 is mounted on a moving body such as an automobile, since the user has to pay attention to the driving operation, it is difficult to gaze at the screen 20a of the touch panel 20.

[0081] In this way, by enlarging or reducing the content display area 16 based on the size of the content display area 16 when the user's slide operation ends, it becomes possible to enlarge or reduce the display that reflects the intention of the touch operation performed by the user.

[0082] Therefore, according to the information display device 10 according to the present embodiment, the user can easily perform an operation to enlarge or reduce the content display area 16 without gazing at the screen 20a of the touch panel 20.

Embodiment

[0083] The information display device 10 according to Embodiment 2 will be described. The information display device 10 according to Embodiment 2 is different in the subroutine for changing the size of the content image in the information display process. Specifically, the information display device 10 according to Embodiment 2 is different from the information display device 10 according to Embodiment 1 in that the default display mode of the content display area 16 is determined by the position of the finger PF when the user ends the touch operation. The remaining points are the same as those of the information display device 10 according to Embodiment 1, and thus the description thereof will be omitted.

[0084] Further, in the content display area 16, which default display mode the content display area 16 will assume is determined by the slide direction of the touch operation immediately before the slide operation ends. For example, if the user performs a touch operation of swiping right from the start of the touch operation until a certain period has elapsed, and then performs a touch operation of swiping left from after the elapse of the certain period until the end of the touch operation, the content display area 16 is reduced.

[0085] FIG. 9 shows a subroutine R2 for changing the size of the content image in step S103 according to the second embodiment. As shown in FIG. 9, the control unit 14 determines whether there has been a slide operation by the user (step S301). For example, the control unit 14 determines that there has been a touch operation based on the fact that the user's finger PF has touched the screen 20a. Also, in this embodiment, the control unit 14 determines whether a touch operation for enlarging or reducing the content display area 16, that is, a slide operation performed in the left - right direction, has been performed.

[0086] If, in the determination in step S301, the control unit 14 determines that there has been no slide operation by the user (step S301: N), the control unit 14 ends the process.

[0087] If, in the determination in step S301, the control unit 14 determines that there has been a slide operation by the user (step S301: Y), the control unit 14 accepts the touch operation. At that time, the control unit 14 enlarges or reduces the content display area 16 according to the touch operation. Therefore, the control unit 14 functions as an input operation reception unit that accepts the touch operation performed on the screen.

[0088] The control unit 14 determines whether or not the received slide operation has ended (step S302). For example, the control unit 14 determines that the slide operation has ended based on the fact that the user's finger PF has left the screen 20a. Incidentally, when the control unit 14 determines in the determination of step S302 that the received slide operation has not ended (step S302: N), the control unit 14 makes the determination of step S302 until the received slide operation ends.

[0089] When the control unit 14 determines in the determination of step S302 that the received slide operation has ended (step S302: Y), the control unit 14 determines whether or not the direction of the slide of the touch operation immediately before the slide operation ends is to the right (step S303). That is, the control unit 14 determines whether to expand or contract the content display area 16 according to the moving direction of the touch operation immediately before the slide operation ends. Incidentally, the control unit 14 determines the direction of the slide of the touch operation based on the input signal from the touch panel 20.

[0090] When the control unit 14 determines in the determination of step S303 that the direction of the slide of the touch operation is to the right (step S303: Y), the control unit 14 determines whether or not the position of the user's finger PF when the slide operation ends, that is, the position of the finger PF on the last screen 20a of the touch operation, is to the right of the border line BR1 (step S304). That is, the control unit 14 determines the default size for expanding the content display area 16 according to the position of the finger PF on the last screen 20a of the touch operation. Incidentally, the control unit 14 determines the position of the finger PF on the last screen 20a of the touch operation based on the input signal from the touch panel 20.

[0091] When the control unit 14 determines in step S305 that the position of the user's finger PF is to the right of the border line BR1 (step S304: Y), the control unit 14 sets the content display area 16 to the second default size (step S305). Therefore, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0092] When the control unit 14 determines in step S304 that the position of the user's finger PF is to the left of the border line BR1 (step S304: N), it makes the content display area 16 the first default size (step S306). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0093] When the control unit 14 determines in the determination of step S303 that the slide direction of the touch operation is to the left (step S303: N), it determines whether the position of the user's finger PF at the end of the slide operation, that is, the position of the finger PF on the last screen 20a of the touch operation, is to the left of the border line BR2 (step S307). That is, the control unit 14 determines a default size for reducing the content display area 16 according to the position of the finger PF on the last screen 20a of the touch operation. Note that the control unit 14 determines the position of the finger PF on the last screen 20a of the touch operation based on the input signal from the touch panel 20.

[0094] When the control unit 14 determines in step S307 that the position of the user's finger PF is to the left of the border line BR2 (step S307: Y), it makes the content display area 16 a closed display (step S308). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0095] When the control unit 14 determines in step S307 that the position of the user's finger PF is to the right of the border line BR2 (step S307: N), it makes the content display area 16 the first default size (step S309). Accordingly, the control unit 14 functions as a display form processing unit that performs the second display form processing and the third display form processing.

[0096] In this way, the control unit 14 makes the content display area 16 the default size based on the position on the last screen 20a where the touch operation was performed.

[0097] As described above, when the content display area 16 is enlarged or reduced on the screen 20a of the touch panel 20, the information display device 10 according to the present embodiment enlarges or reduces the content display area 16 based on the size of the content display area 16 when the user's slide operation ends.

[0098] Therefore, by enlarging or reducing the content display area 16, it becomes possible to easily display the information desired by the user in an appropriate size. In particular, when the information display device 10 is mounted on a moving body such as an automobile, since the user must pay attention to the driving operation, it is difficult to gaze at the screen 20a of the touch panel 20.

[0099] As described above, according to the information display device 10 according to the present embodiment, by enlarging or reducing the content display area 16 based on the position of the finger PF on the screen 20a at the end of the user's touch operation, it is possible to enlarge or reduce the display while more reflecting the intention of the touch operation performed by the user.

[0100] In addition, by determining that the content display area 16 is enlarged or reduced according to the slide direction of the touch operation immediately before the slide operation ends, it is possible to enlarge or reduce the display while more reflecting the intention of the touch operation performed by the user.

Embodiment

[0101] The information display device 10 according to Embodiment 3 will be described. The information display device 10 according to Embodiment 3 is different from the information display devices 10 according to Embodiments 1 and 2 in that an icon image is displayed on a map image. Since the other points are the same as those of the information display devices 10 according to Embodiments 1 and 2, the description thereof will be omitted.

[0102] Further, the information display device 10 according to the present embodiment is different from the information display devices 10 according to Embodiments 1 and 2 in that the display form of the icon image displayed on the map image can be changed.

[0103] Here, an icon image is an image for receiving an input operation that a user performs on a map image. For each icon image, a process to be executed on the map image is pre-assigned. For example, when the user performs a touch operation on an icon image displayed as "wide area", it is possible to display the map image in a wide area, that is, to display the map image with the map scale reduced.

[0104] FIG. 10 shows an example of the display mode of the screen 20a of the touch panel 20. As shown in FIG. 10, on the left side of the screen 20a, a content display area 16 for displaying content images generated by executing the application program 13A and the application program 13B is arranged.

[0105] In the content display area 16, two arranged display frames 16a and 16b are displayed. The two display frames 16a and 16b are arranged side by side vertically. That is, the two display frames 16a and 16b are arranged in a column from the upper side to the lower side of the screen 20a of the touch panel 20.

[0106] Different content images can be displayed in the display frame 16a and the display frame 16b. For example, as in the example of FIG. 10, a content image generated by executing the application program 13A can be displayed in the upper display frame 16a. Also, a content image generated by executing the application program 13B can be displayed in the lower display frame 16b.

[0107] On the right side of the screen 20a, a map display area 17 adjacent to the content display area 16 is arranged. That is, on the screen 20a, the content display area 16 is displayed on the left side with the boundary BO as the boundary, and the map display area 17 is displayed on the right side.

[0108] A map image is displayed in the map display area 17. Also, a route from the current location to the destination may be displayed in the map display area 17.

[0109] In the vicinity of the boundary BO between the content display area 16 and the map display area 17, a wide-area icon image 18a for reducing the scale of the map image and a detailed icon image 18b for increasing the scale of the map image are displayed.

[0110] In the vicinity of the boundary BO between the content display area 16 and the map display area 17, a traffic jam icon 18c for displaying character information indicating the content of accidents and traffic regulations occurring around the information display device 10 is displayed on the map display area 17.

[0111] The user can cause these icon images 18a to 18c to exhibit their functions by performing a touch operation such as tapping these icon images 18a to 18c. That is, these icon images 18a to 18c function as a first icon image 18 that receives an input operation from the user with respect to the map image. Further, the control unit 14 functions as an input operation reception unit that receives a touch operation from the user with respect to the map image, that is, a second input operation.

[0112] At the lower end side of the map display area 17, a place name display icon image 19a for displaying a wide-area place name of the current position of the information display device 10 is displayed. The place name display icon image 19a displays related information related to the map image in character information. For example, the place name display icon 19a displays a wide-area place name such as "〇〇 Ward, Tokyo" on the map display area 17 in character information. That is, the place name display icon image 19a displays a wide-area place name related to the map image as character information.

[0113] In this figure, the place name display icon image 19a has a strip-like form extending in the left-right direction of the screen 20a. The length of the place name display icon image 19a in the left-right direction of the screen 20a is variable, and in this figure, it is displayed in a first predetermined icon size.

[0114] Unlike the first icon image 18, the place name display icon image 19a does not accept a touch operation from the user on the map image. For example, even if the user performs a touch operation of tapping on the place name display icon image 19a, the display mode of the map image is not changed.

[0115] An icon image that does not accept a touch operation, i.e., a second input operation, from the user on the map image and displays related information related to the map image, such as the place name display icon image 19a, is defined as the second icon image 19.

[0116] That is, the control unit 14 functions as a second display control unit that displays the map image together with the first icon image 18 and the second icon image 19 in the map display area 17.

[0117] In the information display device 10 of this embodiment, the size of the content display area 16 changes when the boundary BO moves in the left - right direction by a touch operation of the user on the touch panel 20. Specifically, for example, in response to a left - right swipe operation by the user's finger, the size of the content display area 16 changes as the boundary BO moves in the left - right direction. The size of the content display area 16 changes sequentially following the swipe operation.

[0118] In response to this left - right swipe operation by the user's finger, the size of the place name display icon image 19a changes. Specifically, the size of the place name display icon image 19a is changed according to the size of the content display area 16.

[0119] In this embodiment, since the content display area 16 is on the left side of the screen 20a, for example, when the user performs a touch operation of swiping the finger PF rightward, the boundary BO moves rightward and the content display area 16 expands. Specifically, for example, when the user swipes the finger PF rightward so as to cross the boundary between the content display area 16 and the map display area 17, the content display area 16 is expanded. In other words, when the user swipes the finger PF rightward so as to cross the boundary between the content display area 16 and the map display area 17, the size of the map display area 17 is reduced.

[0120] Also, when the user performs a touch operation of swiping the finger PF leftward, the boundary BO moves rightward and the content display area 16 is reduced. Specifically, for example, when the user swipes the finger PF leftward so as to cross the boundary between the content display area 16 and the map display area 17, the content display area 16 is reduced. In other words, when the user swipes the finger PF leftward so as to cross the boundary between the content display area 16 and the map display area 17, the size of the map display area 17 is expanded. That is, the touch operation in which the user swipes the finger PF leftward and rightward is the first input operation for expanding or reducing the content display area.

[0121] The sizes of the two display frames 16a and 16b are expanded or reduced in the left - right direction of the screen 20a as the content display area 16 expands or reduces. Also, the sizes of the place - name display icon images 19a displayed in the two display frames 16a and 16b are expanded or reduced as the display frames 16a and 16b expand or reduce. Incidentally, the display mode of the content image may be changed as the display frames 16a and 16b expand or reduce.

[0122] Also, the size of the map display area 17 is expanded or reduced in the left - right direction of the screen 20a as the content display area 16 expands or reduces. Further, the size of the place - name display icon image 19a is expanded or reduced in the left - right direction of the screen 20a as the content display area 16 expands or reduces.

[0123] Still, the display position of the first icon image 18 on the screen 20a is changed following the change in the size of the map display area 17, but the screen 20a is not enlarged or reduced in the left - right direction accompanying the enlargement or reduction of the content display area 16.

[0124] FIG. 11 shows an example of the display mode of the screen 20a of the touch panel 20. As shown in FIG. 11, the content display area 16 is displayed in a second default size larger than the first default size.

[0125] For example, the change from the mode of FIG. 10 to the mode of FIG. 11 in the display mode, that is, the change of the content display area 16 from the first default size to the second default size, is caused by a swipe operation of the finger PF in the right direction. Also, the reverse change is caused by, for example, a swipe operation of the finger PF in the left direction.

[0126] In FIG. 11, the place - name display icon image 19a is displayed in a second default icon size whose length in the left - right direction of the screen 20a is shorter than the first default icon size. Also, the place - name displayed on the place - name display icon image 19a is only "Tokyo". Therefore, the number of characters of the related information displayed in the second default icon size is less than the number of characters of the related information displayed in the first default icon size. That is, along with the reduction of the place - name display icon image 19a, a layout change is made in which the number of characters of the related information displayed on the place - name display icon image 19a is decreased.

[0127] FIG. 12 shows an example of the display mode of the screen 20a of the touch panel 20. In FIG. 12, a close display in which the content display area 16 is not displayed on the screen 20a is shown. Therefore, only the map display area 17 is displayed on the screen 20a.

[0128] For example, a change from the mode of FIG. 10 to the mode of FIG. 12 in the display mode, that is, a change from the first default size of the content display area 16 to the closed display, is caused by a swipe operation in the left direction of the finger PF. Also, the reverse change is caused by, for example, a swipe operation in the right direction of the finger PF.

[0129] The content display area 16 is displayed on the screen 20a of the touch panel 20 in three modes: the first default size shown in FIG. 10, the second default size shown in FIG. 11, and the closed display shown in FIG. 12, except during an operation by the finger PF. Similarly, the map display area 17 is also displayed on the screen 20a of the touch panel 20 in the three modes shown in FIGS. 10, 11, and 12.

[0130] That is, the content display area 16 is displayed in only three predetermined display modes, except during an operation by the finger PF. In other words, the boundary BO is at any of the three positions shown in FIGS. 10, 11, and 12, except during an operation by the finger PF.

[0131] Which default display mode the content display area 16 is displayed in is determined according to the size of the content display area 16 when the touch operation ends. In other words, after the touch operation ends, the boundary BO is brought to a predetermined position determined by the position of the boundary BO when the touch operation ends, whereby the content display area 16 is set to the default display mode.

[0132] Also in FIG. 12, the place name display icon image 19a is displayed in the first default icon size. Also, the place name displayed in the place name display icon image 19a is "XX Ward, Tokyo". Therefore, the number of characters of the related information displayed in the first default icon size is larger than the number of characters of the related information displayed in the second default icon size.

[0133] For example, when changing from the second default icon size to the first default icon size, the place name display icon image 19a is enlarged. That is, as the place name display icon image 19a is enlarged, a layout change is made in which the number of characters of the related information displayed in the place name display icon image 19a is increased.

[0134] An example of how the default display mode after the touch operation ends is determined will be described with reference to FIG. 13. In FIG. 13, the second icon image 19, that is, the place name display icon image 19a, shows the state of the first default icon size. Also shown in FIG. 13 are border lines BR1 and BR2 that serve as criteria for what default size the place name display icon image 19a will be.

[0135] As described above, the boundary BO moves by a touch operation (hereinafter referred to as a slide operation) of sliding the finger PF. In the information display device 10 of the present embodiment, at the end of the slide operation, that is, when the finger PF leaves the screen, the default display mode of the content display area 16 is determined according to the position of the boundary BO relative to the border lines BR1 and BR2.

[0136] For example, when the boundary BO is to the right of the border line BR1 at the end of the slide operation, the display mode of the content display area 16 is determined to be the second default size.

[0137] For example, when the boundary BO is between the border line BR1 and the border line BR2 at the end of the slide operation, the display mode of the content display area 16 is determined to be the first default size.

[0138] For example, when the boundary BO is to the left of the border line BR2 at the end of the slide operation, the display mode of the content display area 16 is determined to be closed display.

[0139] The size of the place name display icon image 19a is changed according to the size of the content display area 16. That is, depending on the position of the boundary BO with respect to the border lines BR1 and BR2, which of the default display modes the place name display icon image 19a will take is determined.

[0140] For example, when the content display area 16 is of the first default size and in the closed display, the display mode of the place name display icon image 19a is determined to be the first default icon size. Also, when the content display area 16 is of the second default size, the display mode of the place name display icon image 19a is determined to be the second default icon size.

[0141] Therefore, the control unit 14 functions as a display form processing unit that performs first display form processing for changing the display form of the second icon image 19 based on a touch operation for enlarging or reducing the content display area of the screen 20a.

[0142] As described above, by enlarging or reducing the place name display icon image 19a based on the size of the content display area 16 when the user's touch operation ends, it becomes possible to display in a display mode that reflects the intention of the touch operation performed by the user.

[0143] Also, the change in the display mode of the place name display icon image 19a is not limited to the mode described above.

[0144] The display mode of any of these place name display icon images 19a may be preset, or the user may be allowed to arbitrarily select any display mode.

[0145] FIG. 14 shows information display processing R1 by the information display device 10. As shown in FIG. 14, when the application program 13A and the application program 13B are executed, the control unit 14 starts each of the application program 13A and the application program 13B (step S401).

[0146] The control unit 14 causes the content images generated when each of the application programs 13A and 13B started in step S401 is executed to be displayed in the display frames 16a and 16b. Further, the control unit 14 causes a map image, a first icon image 18, and a second icon image 19 to be displayed in the map display area 17 (step S402). Accordingly, the control unit 14 functions as a first display control unit that causes a display including the content display area 16 for displaying a plurality of contents to be displayed on the screen 20a. Further, the control unit 14 functions as a second display control unit that causes a map image to be displayed together with a plurality of icon images in the map display area 17.

[0147] When a touch operation of swiping by the user is performed in the content display area 16 of the screen 20a, the control unit 14 changes the size of the second icon image 19 displayed in the map display area 17 (step S403). That is, the second icon image 19 can be enlarged or reduced in accordance with the touch operation of the user. Accordingly, the control unit 14 functions as a display form processing unit that performs first display form processing for changing the display form of the second icon image 19 based on a touch operation for enlarging or reducing the content display area of the screen 20a.

[0148] The control unit 14 determines whether the engine of the automobile M has stopped (step S404). When the control unit 14 determines in the determination of step S404 that the engine of the automobile M has not stopped (step S404: N), it returns to the icon image size change process of step S403.

[0149] When the control unit 14 determines in the determination of step S404 that the engine of the automobile M has stopped (step S404: Y), it ends the display on the screen 20a (step S405) and ends each of the application programs 13A and 13B (step S406).

[0150] Figure 15 shows a subroutine R2 for changing the size of the second content image in step S403. As shown in Figure 15, the control unit 14 determines whether there has been a slide operation by the user (step S501). In the determination of step S501, the control unit 14 determines whether there has been a touch operation for enlarging or reducing the content display area 16, that is, whether a slide operation has been performed in the left - right direction.

[0151] If the control unit 14 determines in the determination of step S501 that there has been no slide operation by the user (step S501: N), the process ends.

[0152] If the control unit 14 determines in the determination of step S501 that there has been a slide operation by the user (step S501: Y), it accepts the slide operation. At this time, the control unit 14 enlarges or reduces the content display area 16 and the map display area 17 following the slide operation. In this way, the control unit 14 functions as an input operation reception unit that accepts touch operations performed on the screen 20a.

[0153] The control unit 14 determines whether the accepted slide operation has ended (step S502). For example, the control unit 14 determines that the slide operation has ended based on the fact that the user's finger PF has left the screen 20a. Incidentally, if the control unit 14 determines in the determination of step S502 that the accepted slide operation has not ended (step S502: N), it makes the determination of step S502 until the accepted slide operation ends.

[0154] If the control unit 14 determines in the determination of step S502 that the accepted slide operation has ended (step S502: Y), the enlargement or reduction of the content display area 16 during the touch operation ends.

[0155] It is determined whether the position of the boundary BO at the end of the slide operation, that is, the position of the boundary BO on the screen 20a at the end of the touch operation, is to the right of the border line BR1 (step S503).

[0156] In step S503, when it is determined that the position of the boundary BO is to the right of the border line BR1 (step S503: Y), the control unit 14 causes the icon image to follow the size change of the map display area and sets it to the second default icon size (step S504). Therefore, the control unit 14 functions as a display form processing unit that performs reduction processing of the icon image as the first display form processing.

[0157] The control unit 14 changes the layout of the related information shown in the icon image (step S505). Specifically, the control unit 14 reduces the number of characters in the character information of the related information in the icon image. For example, when the related information of the place name display icon image 19a is character information of "XX Ward, Tokyo", the control unit 14 changes the character information to be displayed on the place name display icon 19a to "Tokyo". In addition, the control unit 14 changes the display position of the first icon image 18 following the movement of the boundary BO. That is, the control unit 14 slides the first icon image 18 along the left - right direction of the screen 20a.

[0158] In step S503, when it is determined that the position of the boundary BO is to the left of the border line BR1 (step S503: N), the control unit 14 determines whether the position of the boundary BO at the end of the slide operation, that is, the position of the boundary BO on the screen 20a at the end of the touch operation, is to the left of the border line BR2 (step S506).

[0159] In step S506, when it is determined that the position of the boundary BO is to the left of the border line BR2 (step S506: Y), the control unit 14 causes the icon image to follow the size change of the map display area and sets it to the first default icon size (step S507). Therefore, the control unit 14 functions as a display form processing unit that performs reduction processing of the icon image as the first display form processing.

[0160] The control unit 14 changes the layout of the related information shown in the icon image (step S508). Specifically, the control unit 14 increases the number of characters in the character information of the related information in the icon image. For example, when the related information of the place name display icon image 19a is the character information "Tokyo", the control unit 14 changes the character information to be displayed on the place name display icon 19a to "XX Ward, Tokyo". Also, the control unit 14 changes the display position of the first icon image 18 following the movement of the boundary BO. That is, the control unit 14 slides the first icon image 18 along the left - right direction of the screen 20a.

[0161] In step S506, when the control unit 14 determines that the position of the boundary BO is to the right of the border line BR2 (step S506: N), it makes the icon image the first default icon size while following the size change of the map display area (step S509). Therefore, the control unit 14 functions as a display form processing unit that performs reduction processing of the icon image as the first display form processing.

[0162] The control unit 14 changes the layout of the related information shown in the icon image (step S510). Specifically, the control unit 14 increases the number of characters in the character information of the related information in the icon image. For example, when the related information of the place name display icon image 19a is the character information "Tokyo", the control unit 14 changes the character information to be displayed on the place name display icon 19a to "XX Ward, Tokyo". Also, the control unit 14 changes the display position of the first icon image 18 following the movement of the boundary BO. That is, the control unit 14 slides the first icon image 18 along the left - right direction of the screen 20a.

[0163] In addition, in this embodiment, it has been described that the icon image is displayed on the screen 20a of the touch panel 20 in two display sizes, the first default icon size and the second default icon size. However, the icon image is not limited to two display modes. For example, a default icon size may be provided between the first default icon size and the second default icon size to increase the display modes for implementation.

[0164] In addition, in this embodiment, how the icon image is displayed in a default display mode is determined by the position of the boundary BO when the touch operation ends. However, how the icon image is displayed in a default display mode can be freely set. For example, according to the amount of slide of the user's slide operation, it may be determined how the icon image is displayed in a default display mode.

[0165] As described above, when the content display area 16 is enlarged or reduced on the screen 20a of the touch panel 20, the information display device 10 according to this embodiment enlarges or reduces the second icon image 19 based on the size of the content display area 16 when the user's slide operation ends.

[0166] Therefore, by enlarging or reducing the second icon image 19, it becomes possible to easily display the icon image desired by the user in an appropriate size. In particular, when the information display device 10 is mounted on a moving body such as an automobile, the possibility that the user operates the first icon image 18 such as changing the scale of map information is higher than the possibility that the user gazes at the second icon image 19. Thus, by enlarging or reducing only the second icon image 19, it is possible to enlarge or reduce the display reflecting the intention of the touch operation performed by the user while maintaining the operability of the information display device 10.

[0167] Therefore, according to the information display device 10 according to this embodiment, the user can easily perform an operation of enlarging or reducing the second icon image 19 without gazing at the screen 20a of the touch panel 20.
