<Embodiment 1>
As a first embodiment of the present invention, a case where the display control device according to the present invention is applied to a navigation device that can be mounted on a vehicle will be described as an example. FIG. 1 is a block diagram showing an example of the configuration of the navigation device. Hereinafter, the vehicle equipped with the navigation device 1 shown in FIG. 1 will be described as “own vehicle”.

The navigation device 1 includes a split view display unit 2, a touch panel 3, an operation input processing unit 9, an interface unit 10, a storage unit 11, a left image generation unit 12, a right image generation unit 13, and the like. And a control unit 14 that performs overall control.

The interface unit 10 is connected between the wireless communication unit 4, the speaker 5, the DVD (Digital Versatile Disk) player 6, the air conditioner 7, the in-vehicle LAN (Local Area Network) 8, and the control unit 14. Various information and various signals are bi-directionally output via the interface unit 10 between the wireless communication unit 4, the speaker 5, the DVD player 6, the air conditioner 7, the in-vehicle LAN 8, and the control unit 14. Hereinafter, in order to simplify the description, instead of describing that one outputs information to the other via the interface unit 10, it is described that one outputs information to the other. The control unit 14 can control the control information by outputting the control information to the wireless communication unit 4, the speaker 5, the DVD player 6, the air conditioner 7, and the in-vehicle LAN 8.

The split view display unit 2 is arranged, for example, on the dashboard of the own vehicle. The split view display unit 2 includes a first image that can be viewed in the direction of the left seat (first direction) but cannot be viewed from the direction of the right seat (hereinafter referred to as “left image”), and the direction of the right seat (first A second image (hereinafter referred to as “right image”) that can be viewed in two directions but not from the direction of the left seat can be displayed on one screen.

As will be described later, the split view display unit 2 displays an icon in the left image (first icon) and an icon in the right image (second icon). Hereinafter, the icon (first icon) in the left image is referred to as “left icon”, and the icon (second icon) in the right image is referred to as “right icon”. In the following description, the left seat is the driver's seat and the right seat is the front passenger seat as an example, but the left seat is the passenger seat and the right seat is the driver seat. Is the same as left and right interchangeably.

For example, a space division display device is applied to the split view display unit 2. FIG. 2 is a schematic cross-sectional view of the display device. A display device 200 illustrated in FIG. 2 includes a display screen 201 and a parallax barrier 202. On the display screen 201, the first pixels 201a for displaying the left image and the second pixels 201b for displaying the right image are alternately arranged along the horizontal direction (left-right direction). The parallax barrier 202 allows the light of the first pixel 201a to pass in the direction of the left seat but blocks the light of the second pixel 201b, and allows the light of the second pixel 201b to pass in the direction of the right seat. Blocks the light of the first pixel 201a. According to such a configuration, the user 101a in the left seat cannot visually recognize the image for the right but can visually recognize the image for left, and the user 101b in the right seat cannot visually recognize the image for the left but visually recognizes the image for right. be able to.

In the configuration in which the space division display device 200 is applied to the split view display unit 2, the parallax barrier 202 allows the light from the plurality of first pixels 201a to pass through in the direction of the left seat, so that the left icon is displayed in a visible manner. When the parallax barrier 202 allows light from the plurality of second pixels 201b to pass in the direction of the right seat, the right icon is displayed so as to be visible. For this reason, the outer edge of the left icon display area corresponds to the first pixel 201a located at the outer edge of the plurality of first pixels 201a used for displaying the left icon, and the right icon display area The outer edge portion corresponds to the second pixel 201b located at the outer edge portion among the plurality of second pixels 201b used for displaying the right icon.

FIG. 3 is a diagram showing a display example of the split view display unit 2 of the space division method, and shows a left image and a right image of one frame. For example, a display device of WVGA (Wide） VGA) has pixels of 800 dots on the horizontal (x axis) and 480 dots on the vertical (y axis) as a whole. The split-view display device of the space division type as shown in FIG. 3 corresponding to the display device of WVGA differs depending on the performance of the display device. For example, the horizontal pixels in the display device of WVGA whose total number is horizontally arranged The first and

second pixels

201a and 201b are double the number, that is, the total number of pixels is 1600 dots horizontally and 480 dots vertically. However, for ease of explanation, the split view display device is composed of a first pixel 201a having 13 dots horizontally and 4 dots vertically and the same number of second pixels 201b. The description will be made assuming that dots are displayed by the first pixel 201a or the second pixel 201b of one dot vertically. Also, the 1-dot x-axis (left-right direction) shift of the icon as shown in FIG. 3 is not visible to the human eye from the normal viewing position, and appears to be displayed at the same position.

In FIG. 3, the outer edge portion (outer frame) of the left icon is indicated by a broken line, and four first pixels 201 a arranged in the horizontal direction are used to display the left icon. It is shown. In FIG. 3, the outer edge portion (outer frame) of the right icon is indicated by a one-dot chain line, and four second pixels 201 b arranged in the horizontal direction are used to display the right icon. It is shown that. Note that the number of first pixels 201a used for displaying the left icon and the number of second pixels 201b used for displaying the right icon are not limited to four.

In the following description, in the configuration in which the space division display device 200 is applied to the split view display unit 2, at least one of the plurality of (four in FIG. 3) first pixels 201a used for displaying the left icon is used. Among the plurality (four in FIG. 3) of second pixels 201b used for displaying the right icon, the second pixel 201b (second pixel 201b corresponding to the alternate long and short dash line in FIG. 3) located at the outer edge is sandwiched. In this case, at least a part of the display area of the left icon and at least a part of the display area of the right icon overlap each other on the screen of the split view display unit 2. In this configuration, at least one of the plurality (four in FIG. 3) of the second pixels 201b used for displaying the right icon is a plurality (four in FIG. 3) used for displaying the left icon. Even when sandwiched between first pixels 201a (first pixels 201a corresponding to broken lines in FIG. 3) located on the outer edge of the first pixels 201a, at least a part of the display area of the left icon, It is noted that at least a part of the display area of the right icon overlaps with each other on the screen of the split view display unit 2. On the other hand, in the configuration, when one of the second pixel 201b used for displaying the right icon and the first pixel 201a used for displaying the left icon is not sandwiched between the other, the left icon The display area of the right icon and the display area of the right icon are separated from each other on the screen of the split view display unit 2.

The configuration in which the space division display device 200 is applied to the split view display unit 2 has been described above. However, the present invention is not limited to this, and for example, a time-division display device may be applied to the split view display unit 2. FIG. 4 is a schematic cross-sectional view of the display device. The display device 250 illustrated in FIG. 4 includes a display screen 251 and a parallax barrier 252. The display screen 251 displays the left image by the pixel 251c in the first period, and displays the right image by the pixel 251c in the second period. The parallax barrier 252 allows the light of the pixel 251c to pass in the direction of the left seat in the first period, but blocks the light of the pixel 251c in the direction of the right seat, and in the direction of the right seat in the second period. The light of the pixel 251c is allowed to pass but the light of the pixel 251c is blocked with respect to the direction of the left seat. FIG. 4 shows the state of the first period.

According to the configuration described above, the left seat user 101a cannot visually recognize the right image but can visually recognize the left image, and the right seat user 101b cannot visually recognize the left image but visually recognize the right image. can do. Note that the eyes of the user 101b in the right seat do not receive the light of the pixel 251c from the split view display unit 2 in the first period. However, since the first period is set to be very short, the right seat user 101b does not recognize that the eyes are not receiving light in the first period. On the other hand, due to the afterimage effect of light received by the eyes in the second period, the user 101b in the right seat recognizes that the image of the second period is also displayed in the first period. Similarly, the fact that the eyes are not receiving light in the second period is not recognized by the user 101a in the left seat, and the image of the first period is also displayed in the second period due to the afterimage effect of the light received in the first period. Is recognized by the user 101a in the left seat.

In the configuration in which the time division display device 250 is applied to the split view display unit 2, the parallax barrier 252 allows the light from the plurality of pixels 251c to pass in the direction of the left seat in the first period so that the left icon can be visually recognized. The right icon is displayed so as to be visible by allowing light from the plurality of pixels 251c to pass in the direction of the right seat in the second period. Therefore, the outer edge of the left icon display area corresponds to the pixel 251c located at the outer edge of the plurality of pixels 251c used for displaying the left icon, and the outer edge of the right icon display area is This corresponds to the pixel 251c located at the outer edge among the plurality of pixels 251c used for displaying the right icon.

5 (a) and 5 (b) are diagrams showing a display example of the time-division split view display unit 2, and a left image and a right image of one frame are shown. For example, as described above, a WVGA display device has pixels of 800 dots on the horizontal (x axis) and 480 dots on the vertical (y axis) as a whole. The time-division split-view display device corresponding to the WVGA display device as shown in FIGS. 5A and 5B differs depending on the performance of the display device, for example, 800 dots horizontally and vertically. The pixel 251c is composed of 480 dots. However, for ease of explanation, the split view display device is configured with pixels 251c having 13 dots horizontally and 4 dots vertically, and icons are displayed by pixels 251c having 3 dots horizontally and 1 dot vertically. It will be described as a thing.

In FIG. 5A, the outer edge (outer frame) of the left icon displayed in the first period is indicated by a broken line, and three pixels arranged in the horizontal direction to display the left icon. It is shown that 251c is used. In FIG. 5B, the outer edge portion (outer frame) of the right icon displayed in the second period is indicated by a broken line, and 3 arranged in the horizontal direction to display the right icon. It is shown that two pixels 251c are used. Note that the number of pixels 251c used for displaying the left icon and the number of pixels 251c used for displaying the right icon are not limited to three.

In the following description, in the configuration in which the time-division display device 250 is applied to the split view display unit 2, at least one of the plurality of pixels 251c used for displaying the left icon in the first period and the second period When at least one of the plurality of pixels 251c used for displaying the right icon matches, at least a part of the display area of the left icon and at least a part of the display area of the right icon It is noted that they overlap each other on the screen of the split view display unit 2. On the other hand, when there is no pixel 251c used for displaying the left icon in the first period and used for displaying the right icon in the second period, the display area of the left icon and the right icon It is noted that the display area is separated on the screen of the split view display unit 2.

Although a detailed description of the configuration is omitted, the split view display unit 2 may be applied with a display device that combines a space division method and a time division method. For example, at least a part of the pixels used for displaying the left icon in the first period is sandwiched between pixels located on the outer edge among the plurality of pixels used for displaying the right icon in the second period. Or at least some of the pixels used for displaying the right icon in the second period are pixels located at the outer edge of the plurality of pixels used for displaying the left icon in the first period. When sandwiched, at least a part of the display area for the left icon and at least a part of the display area for the right icon overlap each other on the screen of the split view display unit 2. On the other hand, when one of the pixel used for displaying the left icon in the first period and the pixel used for displaying the right icon in the second period is not sandwiched between the other, the display of the left icon is displayed. It is noted that the area and the display area for the right icon are separated on the screen of the split view display unit 2.

Note that specific configurations of a display device using the split view method are disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-078080 and International Publication No. 2012/070444. Although not mentioned in the above description, pixel scanning is performed in a short period (for example, 1/30 [second]) in both the space division method and the time division method.

1, the detection surface of the touch panel 3 is arranged on the screen of the split view display unit 2. The touch panel 3 (input unit) uniformly accepts an operation on the left image for executing the application function and an operation on the right image for executing the application function. As shown in FIG. 6, the touch panel 3 according to the first embodiment has a position of a point on the detection surface where the distance from the indicator such as a finger of the user (driver and passenger in the passenger seat) is shortest ( A three-dimensional position (X, Y, Z) including X and Y) and a distance Z between the indicator and the detection surface (the point) is detected as the position of the indicator. When the distance Z between the indicator (finger 21 in FIG. 6) and the detection surface of the touch panel 3 is 0, the indicator (finger 21 in FIG. 6) contacts (touches) the detection surface of the touch panel 3. Means that

Such a touch panel 3 includes, for example, a three-dimensional position of the indicator based on a capacitance formed between the detection surface and the indicator (a three-dimensional position of the indicator with respect to a reference point on the detection surface). ) Is applied. The touch panel 3 periodically detects the three-dimensional position of the indicator as described above, and outputs a signal indicating the three-dimensional position to the operation input processing unit 9.

The wireless communication unit 4 communicates with the server via, for example, DSRC (Dedicate Short Range Communication) and a mobile phone. The wireless communication unit 4 outputs information received from the server (for example, downloaded information) to the control unit 14 or transmits information output from the control unit 14 to the server. The wireless communication unit 4 receives radio broadcasts and television broadcasts and outputs information acquired from the broadcasts to the control unit 14.

Speaker 5 (audio output unit) outputs audio based on the audio signal output from the control unit 14.

The DVD player 6 reproduces AV (Audio-video) information recorded on the DVD, and outputs the AV information to the control unit 14.

The air conditioner 7 adjusts the temperature and humidity in the vehicle interior under the control of the control unit 14.

The in-vehicle LAN 8 communicates with the own vehicle ECU (Electronic Control Unit), GPS (Global Positioning System) device, and the like. For example, the in-vehicle LAN 8 outputs the speed of the own vehicle acquired from the ECU and the current position (for example, latitude and longitude) of the own vehicle acquired from the GPS device to the control unit 14.

The icon position information indicating the position of the icon displayed on the split view display unit 2 is input from the control unit 14 to the operation input processing unit 9. Based on the icon position information and an output signal of the touch panel 3 (a signal indicating the three-dimensional position of the indicator), the operation input processing unit 9 displays the icon displayed on the touch panel 3 and eventually the split view display unit 2. It is determined whether or not an operation has been performed on the above. Here, the operation input processing unit 9 indicates that the output signal of the touch panel 3 indicates the distance Z = 0, and the position of the indicator indicated by the output signal overlaps the display area of the left icon (the indicator is If it is determined that the operation is performed on the left icon, it is determined that the operation is performed on the left icon. Similarly, the operation input processing unit 9 indicates that the output signal of the touch panel 3 indicates the distance Z = 0, and the position of the indicator indicated by the output signal overlaps the display area of the right icon (the indicator indicates If it is determined that the operation is performed on the right icon, it is determined that the operation is performed on the right icon. Then, the operation input processing unit 9 outputs the determination result to the control unit 14.

As described above, the first embodiment will be described on the assumption that the operation input processing unit 9 performs the process of determining whether or not an operation on an icon or the like displayed on the split view display unit 2 has been performed. The determination process may be performed by the control unit 14. In FIG. 1, the operation input processing unit 9 is provided separately from the touch panel 3 and the control unit 14, but is not limited thereto, and may be provided in the touch panel 3 as a function of the touch panel 3. However, the control unit 14 may be provided as a function of the control unit 14.

The storage unit 11 includes, for example, a hard disk drive, a DVD and its drive device, a Blu-ray disc and its drive device, or a storage device such as a semiconductor memory. The storage unit 11 stores information used for the control unit 14 in addition to a program necessary for the control unit 14 to operate. The information used for the control unit 14 includes, for example, an application (application software), an image in which icons operated when executing the function of the application, map information, and the like. In the following description, an image (for example, an image corresponding to FIG. 8A and FIG. 8B) in which an icon operated when executing an application function is arranged is referred to as an “icon arrangement image”. I write. The “icon arrangement image” includes an image in which an icon is displayed on the map information.

The left image generation unit 12 generates a display signal for displaying the left image based on the display information output from the control unit 14, and outputs the display signal to the split view display unit 2. When receiving the display signal from the left image generation unit 12, the split view display unit 2 displays the left image based on the display signal.

The right image generation unit 13 generates a display signal for displaying the right image based on the display information output from the control unit 14, and outputs the display signal to the split view display unit 2. When receiving the display signal from the right image generation unit 13, the split view display unit 2 displays the right image based on the display signal.

Here, the display signal generated by the left image generation unit 12 includes, for example, (1, 1), (2, 1),..., (800, 1), (1) for each of a plurality of pixels used in the left image. , 2),... (800, 2),..., (800, 480). Similarly, the display signal generated by the right image generation unit 13 is also referred to as (1, 1), (1, 2),..., (800, 480) for each of a plurality of pixels used in the right image. Contains pixel numbers assigned in order. Therefore, when the pixel number of at least one pixel used for displaying the left icon matches the pixel number of at least one pixel used for displaying the right icon, at least the display area of the left icon is displayed. This corresponds to that a part and at least a part of the display area of the right icon overlap each other on the screen of the split view display unit 2. Here, (x, y) indicates a pixel position corresponding to an xy coordinate in which the upper left on the screen is (1, 1), the x axis is positive in the right direction, and the y axis is positive in the downward direction.

The control unit 14 includes, for example, a CPU (Central Processing Unit), and when the CPU executes a program stored in the storage unit 11, the navigation device 1 executes various applications, and thus The speaker 5 and the like can be controlled according to the executed application.

For example, when the navigation application is executed, the control unit 14 determines a route from the current position to the destination based on the current position of the host vehicle, the destination based on the output signal of the touch panel 3, and the map information. Search is performed, and display information for displaying guidance along the route and a voice signal for outputting the guidance by voice are generated. As a result, the above guidance is displayed as a left image or a right image, and the above guidance voice is output from the speaker 5.

Further, for example, when a DVD playback application is executed, the control unit 14 generates display information for displaying AV information from the DVD player 6 and an audio signal for outputting the AV information as audio. . As a result, the video stored in the DVD is displayed as the left image or the right image, and the audio stored in the DVD is output from the speaker 5.

In addition, the control unit 14 acquires one icon arrangement image corresponding to one or more applications that can be executed on the left image side (executable from the left image side) from the storage unit 11, and the acquired icon arrangement image Is displayed as a left image. As a result, an icon that is an operation target for executing the function of the application on the left image side is displayed on the split view display unit 2 (left image). Hereinafter, an icon arrangement image (for example, an image corresponding to FIG. 8A) that can be displayed as the left image is referred to as a “left icon arrangement image”. The icon in the left icon arrangement image displayed as the left image is the above-described left icon.

Similarly, the control unit 14 acquires, from the storage unit 11, one icon arrangement image corresponding to one or more applications that can be executed on the right image side (executable from the right image side). The icon arrangement image is displayed as the right image. As a result, an icon that is an operation target for executing the function of the application on the right image side is displayed on the split view display unit 2 (right image). Hereinafter, an icon arrangement image that can be displayed as a right image (for example, an image corresponding to FIG. 8B) will be referred to as a “right icon arrangement image”. The icon in the right icon arrangement image displayed as the right image is the right icon described above.

Now, based on the output signal of the touch panel 3 (a signal indicating the three-dimensional position of the indicator), the operation input processing unit 9 described above performs a first action defined in advance as an action immediately before operating the left icon. It is determined whether the determination has been made, and the determination result is output to the control unit 14. Here, when the left icon is displayed, the operation input processing unit 9 has the distance Z indicated by the output signal of the touch panel 3 larger than 0 and equal to or smaller than a predetermined threshold ZL1 (for example, about 3 to 10 cm). If it is determined that the action immediately before operating the left icon (first action) is performed, otherwise, the action immediately before operating the left icon (first action) is not performed. judge.

Then, as will be described in detail below, when the operation input processing unit 9 determines that the action immediately before operating the left icon is performed or is being performed based on the output signal from the touch panel 3 The control unit 14 causes the first area corresponding to the display area of the left icon in the right image (hereinafter referred to as “left icon corresponding area”) to be displayed in an identifiable manner.

FIG. 7 is a flowchart showing the operation of the navigation device 1 according to the first embodiment. The operation shown in FIG. 7 is performed by the CPU executing a program stored in the storage unit 11. Hereinafter, operation | movement of the navigation apparatus 1 is demonstrated using FIG.

First, in step S1, when an operation for executing the initial operation is performed, the control unit 14 executes the initial operation. Here, as an initial operation, the control unit 14 acquires from the storage unit 11 an application to be initially executed on the left image side and the right image side, and executes the application.

In step S2, the control unit 14 acquires the left icon arrangement image corresponding to the application executed on the left image side from the storage unit 11, and also corresponds to the application executed on the right image side. A right icon arrangement image is acquired from the storage unit 11.

In step S3, the control unit 14 displays the acquired left icon arrangement image as the left image of the split view display unit 2, and displays the acquired right icon arrangement image as the right image of the split view display unit 2.

FIGS. 8A and 8B are diagrams showing display examples of the left image and the right image in step S3 of the navigation device 1 (split view display unit 2) according to the first embodiment. In the left image in FIG. 8A, left icons L1, L2, L3, L4, L5, and L6 (hereinafter, these icons may be collectively referred to as “left icons L1 to L6”) are arranged. An icon arrangement image is displayed. In the right image of FIG. 8B, right icons R1, R2, R3, R4, and R5 (hereinafter, these icons may be collectively referred to as “right icons R1 to R5”) are arranged. The icon arrangement image for the right is displayed.

In the first embodiment, a case will be described in which the display areas of the left icons L1 to L6 and the display areas of the right icons R1 to R5 are arranged apart from each other on the screen of the split view display unit 2. The case where these are arranged to overlap each other on the screen of the split view display unit 2 will be described in the third embodiment.

7, the operation input processing unit 9 determines whether or not an action immediately before operating the left icon has been performed (whether or not the distance Z is greater than 0 and less than or equal to the threshold ZL1). If it is determined that the action immediately before the left icon is operated, the process proceeds to step S5. If it is determined that the action is not performed, step S4 is performed again.

Note that the operation input processing unit 9 here, when the indicator approaches the detection surface of the touch panel 3 at a distance equal to or smaller than the threshold value ZL1, determines whether the action immediately before operating the left icon has been performed, It is determined that the action immediately before the left icon is operated without distinguishing whether the action immediately before the operation is performed. However, the determination is not limited to this. For example, the control unit 14 operates the left icon by considering not only the distance Z between the indicator and the detection surface but also the two-dimensional position (X, Y) of the indicator shown in FIG. You may distinguish and determine whether the last action was implemented or the last action which operated the right icon was implemented. For example, when the operation input processing unit 9 determines that the position (X, Y, Z) of the indicator shown in FIG. 6 is located within a dome-shaped (hemispherical) space region covering the left icon. The control unit 14 may determine that an action immediately before operating the left icon is performed. The same applies to steps S8, S24, and S28 described later.

When step S4 is performed again, if the map is displayed as a left image or a right image and the position of the vehicle has changed, the control unit 14 responds to the change. You may scroll the map.

In step S5, the control unit 14 displays the left icon corresponding area in the right image so as to be identifiable (performs display so as to be identifiable).

9 (a) and 9 (b) are diagrams showing display examples of the left image and the right image in step S5 of the navigation device 1 according to the first embodiment.

The left image in FIG. 9 (a) is the same as the left image in FIG. 8 (a). On the other hand, as shown in FIG. 9B, the control unit 14 has the left icon corresponding areas LA1, LA2, LA3, LA4 at the same position as the left icons L1, L2, L3, L4, L5, L6 in the right image. , LA5, LA6 (hereinafter also referred to as “left icon corresponding areas LA1 to LA6”). Here, the control unit 14 displays the same icons as the left icons L1 to L6 in the left icon corresponding areas LA1 to LA6, respectively, so that the left icon corresponding areas LA1 to LA6 are displayed in an identifiable manner. Further, the display area of the left icons L1 to L6 in the left image and the left icon corresponding areas LA1 to LA6 in the right image overlap each other on the screen of the split view display unit 2.

Here, when the left image in FIG. 8A and the right image in FIG. 8B are displayed, the user (driver) of the left seat touches or drags the left icons L1 to L6. Assume that a finger or the like approaches the detection surface of the touch panel 3 in an attempt to perform an operation such as. In this case, the user (driver) in the left seat visually recognizes the left image in FIG. 9A as the left image in FIG. 8A by the operations in steps S4 and S5. As a result, it is considered that the user (driver) in the left seat operates the left icon as usual.

On the other hand, when the left image in FIG. 8 (a) and the right image in FIG. 8 (b) are displayed, the user in the right seat (passenger in the passenger seat) is in an area other than the right icons R1 to R5. As a result of the finger approaching the detection surface of the touch panel 3 by trying to touch the right icon R1 to R5 casually or trying to perform an operation such as a touch operation or a drag operation on the right icons R1 to R5, Is greater than 0 and reaches a predetermined threshold value ZL1. In this case, the user in the right seat (passenger in the passenger seat) adds the left icon corresponding areas LA1 to LA6 to the right image in FIG. 8B by the operations in steps S4 and S5. The right image is visually recognized. Therefore, when the right seat user (passenger in the passenger seat) does not intend to operate the left icons L1 to L6, the same image as the left icons L1 to L6 displayed in the left icon corresponding areas LA1 to LA6. Is considered not to touch (do not operate).

In step S6 of FIG. 7, the operation input processing unit 9 determines whether or not an operation has been performed on the left icons L1 to L6 or the right icons R1 to R5. When it is determined that the operation for the left icons L1 to L6 or the right icons R1 to R5 is performed, the process proceeds to step S7, and when it is determined that the operation is not performed, the process proceeds to step S8.

In step S7, the control unit 14 executes the function of the application corresponding to the operated icon. Thereafter, the process proceeds to step S8. If an icon arrangement image is associated with the operated icon in advance and stored in the storage unit 11, the process returns from step S 7 to step S 3, and the icon arrangement image is displayed in the split view display unit 2. May be displayed.

In step S8, the operation input processing unit 9 performs the determination in step S4 again. That is, the operation input processing unit 9 determines whether an action immediately before operating the left icon is being performed (whether the distance Z is greater than 0 and less than or equal to the threshold ZL1). If it is determined that the action immediately before the left icon is operated, the process returns to step S6, and if it is determined not to be performed, the process proceeds to step S9.

Here, the action determined to be in progress may be an action that continues from the action determined to be performed in step S4, or may be an action that does not continue. As the latter action, that is, the action that does not continue from the action determined to be performed in step S4, for example, the case where the indicator is trembling in a situation where the distance Z is in the vicinity of the threshold value ZL1 can be considered. In this case, LPF (Low Pass Filter) signal processing correction may be applied to the distance Z so that the determination result does not vary depending on the detection timing.

In step S9, the control unit 14 returns from the display of the right image (FIG. 9B) in step S5 to the display of the original right image (FIG. 8B) in step S3. Then, it returns to step S4.

<Effect>
According to the navigation device 1 according to the first embodiment as described above, when it is determined that the action immediately before the left icon is operated or is being performed, the left icon is supported in the right image. The area is displayed in an identifiable manner. Thereby, it can suppress that the user (passenger of a passenger seat) of a right seat operates the left icon unintentionally. In addition, it is not necessary to always display the left icon corresponding area, so that it is easy to see the right icon, and the right seat user (passenger in the passenger seat) can be compared to the case where the left icon and the right icon are always displayed. Can also be expected to easily distinguish the right icon and the left icon.

In the above description, the “first image” is a left image, the “first action” is an action immediately before the left icon is operated, and the “first area” is a display area of the left icon in the right image. It was explained as being. However, the present invention is not limited to this. The “first image” is a right image, the “first action” is an action immediately before the right icon is operated, and the “first region” is a right image in the left image. It may be an icon display area. Thereby, it can suppress that the user (passenger of a passenger seat) of a right seat operates the left icon unintentionally.

<Modification 1 of Embodiment 1>
In the first embodiment, as shown in FIGS. 9A and 9B, the control unit 14 displays the same images as the left icons L1 to L6 in the left icon corresponding areas LA1 to LA6, respectively. In the right image, the left icon corresponding areas LA1 to LA6 are displayed in an identifiable manner. However, the images displayed in the left icon corresponding areas LA1 to LA6 are not limited to the same images as the left icons L1 to L6.

For example, the control unit 14 performs a predetermined process such as a process for changing the color or brightness or a blur process on the left icons L1 to L6, and the icon image obtained by the process is displayed in the left icon corresponding region. Each of LA1 to LA6 may be displayed.

Further, as shown in FIGS. 10 (a) and 10 (b), the control unit 14 adds a color or color to the original image (background image) displayed in the left icon corresponding areas LA1 to LA6 in the right image. Processing to change the brightness (in FIG. 10B, the color difference corresponds to the difference in the density of the hatched fine points) or predetermined processing such as blurring processing, and an image obtained by the processing is The icons may be displayed in the left icon corresponding areas LA1 to LA6.

Since the left icon corresponding areas LA1 to LA6 in the right image need only be distinguishable from other areas, the left icon corresponding areas LA1 to LA6 display only a frame without displaying characters or symbols. It may be. For important icons and icons that can be pressed, characters indicating that they are important and icons that may be pressed may be added to the left icon corresponding areas LA1 to LA6. .

Further, as shown in FIGS. 11A and 11B, for example, the control unit 14 has an original image (background image) with a transmittance of 50% and a transmittance of 50% in the left icon corresponding areas LA1 to LA6. Composite images obtained by combining the images of the left icons L1 to L6 (shown by broken lines in FIG. 11B) may be displayed in the left icon corresponding areas LA1 to LA6, respectively.

Also, as shown in FIGS. 12A and 12B, the control unit 14 may display predetermined graphic images in the left icon corresponding areas LA1 to LA6. Further, the control unit 14 is obtained, for example, by combining an original image (background image) with a transmittance of 50% of the left icon corresponding regions LA1 to LA6 and an image of a predetermined graphic with a transmittance of 50%. The composite image may be displayed in each of the left icon corresponding areas LA1 to LA6.

Further, as shown in FIGS. 13A and 13B, when there are a plurality of left icon corresponding regions, the control unit 14 surrounds the plurality of left icon corresponding regions LA1 to LA6 in the right image. The region LE1 may be displayed instead of the left icon corresponding regions LA1 to LA6. As a result, when there are a plurality of left icons in a certain area, an area such as the area LE1 can be displayed in the right image.

The same effects as those of the first embodiment can also be obtained by the navigation device 1 according to the first modification described above. 9 and 11, the right seat user (passenger in the passenger seat) has received a request for an operation on the left icons L1 to L6 from the left seat user (driver). In this case, the operation can be performed on behalf of the driver.

In the above description, the control unit 14 displays all the left icon corresponding areas LA1 to LA6 so as to be identifiable when it is determined that the action immediately before the left icon is operated or is being executed. I let you. However, the present invention is not limited to this, and the control unit 14 determines that at least one of the left icon corresponding areas LA1 to LA6 when it is determined that the action immediately before the left icon is operated or is being executed. One (for example, one left icon corresponding region closest to the indicator) may be displayed in an identifiable manner. Further, not only the left icon corresponding areas LA1 to LA6 are displayed for any one of the icons, but also within a predetermined distance from the position of the indicator such as (X, Y) coordinates or in advance including the position. The left icon corresponding areas LA1 to LA6 located within a predetermined range may be displayed.

<Modification 2 of Embodiment 1>
In the first embodiment, the configuration in which the electrostatic touch panel is applied to the touch panel 3 has been described. However, the configuration of the navigation device 1 is not limited to this, and may be a configuration described in the following first to third examples.

In the configuration of the first example, an infrared touch panel in which a mechanism for detecting an indicator using infrared rays is provided in two stages perpendicular to the detection surface is applied to the touch panel 3. In the touch panel 3 configured in this manner, instead of the above-described distance Z, the indicator is in proximity to the detection surface (a state where the indicator is detected only in the upper stage), and the indicator is in contact with the detection surface. Either the state (the state in which the indicator is detected in the upper stage or the lower stage) or any other state is detected.

In the configuration of the first example, the operation input processing unit 9 indicates that the output signal of the touch panel 3 indicates that the indicator is in contact with the detection surface, and the position of the indicator indicated by the output signal is When it is determined that the left icon overlaps, it is determined that the operation for the left icon has been performed. The same applies to the right icon. Further, the operation input processing unit 9 immediately before operating the left icon when the output signal of the touch panel 3 indicates a state in which the indicator is close to the detection surface when the left icon is displayed. It is determined that the act (first action) has been performed.

Even with the configuration of the first example as described above, the same effect as in the first embodiment can be obtained.

Further, in the configuration of the second example, instead of the above-described distance Z, it is possible to detect a touch operation in which the indicator lightly touches the touch panel, and an amount by which the detection surface is pushed by the indicator (push amount). A simple electrostatic touch panel is applied to the touch panel 3.

In the configuration of the second example, the operation input processing unit 9 determines that the pressing amount indicated by the output signal of the touch panel 3 is larger than a predetermined value, and the position of the indicator indicated by the output signal is the left icon. Is determined to have overlapped with the icon, it is determined that a push operation has been performed on the icon. The same applies to the right icon. Further, when the operation input processing unit 9 determines that the push amount indicated by the output signal of the touch panel 3 is equal to or less than a predetermined value and the position of the indicator indicated by the output signal overlaps with the left icon. It is determined that a touch operation has been performed on the left icon. When the operation input processing unit 9 determines that the touch operation has been performed on the left icon, the operation input processing unit 9 determines that the action immediately before the left icon is operated (first action).

Even with the configuration of the second example as described above, the same effect as in the first embodiment can be obtained.

Further, in the configuration of the third example, an electrostatic touch panel that can detect the three-dimensional position of the indicator and can detect both the amount of pushing of the indicator is applied to the touch panel 3. FIG. 14 is a flowchart showing an operation of the navigation device 1 according to the second modification including the electrostatic touch panel. The flowchart shown in FIG. 14 is the same as the flowchart shown in FIG. 7 except that Step S6 is replaced with Step S11, and Steps S12 and S13 are added between Step S11 and Step S7. Steps S11, S12 and S13 will be mainly described.

In step S11 after step S5, the operation input processing unit 9 determines whether the touch operation on the left icon or the right icon has been performed by performing the determination described in the configuration of the second example.

If it is determined in step S11 that the touch operation on the left icon or the right icon is performed, the process proceeds to step S12. If it is determined that the touch operation is not performed, the process proceeds to step S8.

In step S12, the control unit 14 highlights the touched icon.

In step S13, the operation input processing unit 9 determines whether or not a push operation has been performed on the touch-operated icon by performing the determination described in the configuration of the second example.

If it is determined in step S13 that the push operation has been performed, the process proceeds to step S7, and the function of the application corresponding to the icon for which the push operation has been performed is executed. On the other hand, when it determines with pushing operation not having been implemented in step S13, it returns to step S11. When returning from step S13 to step S11, the highlight display in step S12 may be canceled as necessary.

Even with the configuration of the third example as described above, the same effect as in the first embodiment can be obtained.

<Embodiment 2>
In the first embodiment, when it is determined that the action immediately before the left icon is operated or is being performed, the left icon corresponding area is displayed in an identifiable manner in the right image. In the second embodiment of the present invention, the same display is performed on the left image. Hereinafter, the configuration of the navigation device 1 according to the second embodiment will be described.

Note that the block configuration of the navigation device 1 according to the second embodiment is the same as the block configuration of the first embodiment, and therefore illustration thereof is omitted. And in the navigation apparatus 1 which concerns on this Embodiment 2, the same code | symbol is attached | subjected about what is the same as or similar to the component demonstrated in Embodiment 1, and it demonstrates centering around a different point below.

The operation input processing unit 9 according to the second embodiment determines, based on the output signal of the touch panel 3, whether or not a second action predefined as an action immediately before operating the right icon has been performed, The determination result is output to the control unit 14. Here, when the right icon is displayed, the operation input processing unit 9 causes the distance Z indicated by the output signal of the touch panel 3 to be greater than 0 and less than a predetermined threshold value ZR1 (for example, about 3 to 10 cm). When it is determined that the right icon is operated (second action), it is determined that the action just before the right icon is operated. Otherwise, the right action (second action) is performed. Judge that it was not done.

The threshold value ZR1 may be a value different from the threshold value ZL1 described in the first embodiment, but here it is assumed to be the same value in order to simplify the description. In such a configuration, determining whether or not an action immediately before operating the left icon is performed and determining whether or not an action immediately before operating the right icon is performed are substantial. Is the same.

Then, as will be described in detail below, when the operation input processing unit 9 determines that the action immediately before operating the right icon is performed or is being performed based on the output signal from the touch panel 3 The control unit 14 causes the second area corresponding to the display area of the right icon in the left image (hereinafter referred to as “right icon corresponding area”) to be displayed in an identifiable manner.

FIG. 15 is a flowchart showing the operation of the navigation device 1 according to the second embodiment. The flowchart shown in FIG. 15 is the same as the flowchart shown in FIG. 7 except that steps S4 to S9 are replaced with steps S24 to S29. Therefore, steps S24 to S29 will be mainly described below. .

In step S3 after steps S1 and S2, the control unit 14 displays the acquired left icon arrangement image as the left image of the split view display unit 2, and displays the acquired right icon arrangement image on the right of the split view display unit 2. Display as an image. Here, it is assumed that the left image and the right image shown in FIGS. 8A and 8B are displayed on the split view display unit 2 in step S3.

In step S24 after step S3, the operation input processing unit 9 determines whether or not an action immediately before the left icon is operated (whether the distance Z is greater than 0 and less than or equal to the threshold ZL1). At the same time, it is determined whether or not an action immediately before the right icon is operated (whether or not the distance Z is greater than 0 and less than or equal to the threshold value ZR1). Here, as described above, since the threshold value ZR1 and the threshold value ZL1 are the same value, the former determination and the latter determination are substantially the same. If it is determined that the action immediately before the left icon is operated (act immediately before the right icon is operated), the process proceeds to step S25. If it is determined that the action is not performed, step S24 is performed again. When step S24 is performed again, if the map is displayed as the left image or the right image and the position of the vehicle has changed, the control unit 14 responds to the change. You may scroll the map.

In step S25, the control unit 14 displays the left icon corresponding region in the right image so as to be identifiable, and displays the right icon corresponding region in the left image so as to be identifiable.

16 (a) and 16 (b) are diagrams illustrating display examples of the left image and the right image in step S25 of the navigation device 1 according to the second embodiment.

As shown in FIG. 16B, the control unit 14 generates left icon corresponding areas LA1 to LA6 at the same positions as the left icons L1 to L6 in the right image, as in the first embodiment. Here, the control unit 14 displays the same icons as the left icons L1 to L6 in the left icon corresponding areas LA1 to LA6, respectively, so that the left icon corresponding areas LA1 to LA6 are displayed in an identifiable manner.

In the second embodiment, as well, as shown in FIG. 16A, the control unit 14 places the right icon corresponding area in the left image at the same position as the right icons R1, R2, R3, R4, and R5. RA1, RA2, RA3, RA4, and RA5 (hereinafter also referred to as “right icon corresponding areas RA1 to RA5”) are generated. Here, the control unit 14 displays the same icons as the right icons R1 to R5 in the right icon corresponding areas RA1 to RA5, respectively, so that the right icon corresponding areas RA1 to RA5 are displayed in an identifiable manner. Also, the display areas for the right icons R1 to R5 in the right image and the right icon corresponding areas RA1 to RA5 in the left image overlap each other on the screen of the split view display unit 2.

In step S26 of FIG. 15, the operation input processing unit 9 determines whether or not an operation has been performed on the left icons L1 to L6 or the right icons R1 to R5, as in step S6. If it is determined that the operation for the left icons L1 to L6 or the right icons R1 to R5 is performed, the process proceeds to step S27, and if it is determined that the operation is not performed, the process proceeds to step S28.

In step S27, the control unit 14 executes the function of the application corresponding to the operated icon as in step S7. Thereafter, the process proceeds to step S28. When the icon arrangement image is associated with the operated icon in advance and stored in the storage unit 11, the process returns from step S27 to step S3, and the icon arrangement image is displayed in the split view display unit 2. May be displayed.

In step S28, the operation input processing unit 9 performs the determination in step S24 again. That is, the operation input processing unit 9 determines whether an action immediately before operating the left icon is being performed (whether the distance Z is greater than 0 and less than or equal to the threshold value ZL1), and the right icon It is determined whether or not the action immediately before the operation is being performed (whether or not the distance Z is greater than 0 and less than or equal to the threshold value ZR1). If it is determined that the action immediately before operating the left icon (act immediately before operating the right icon) is being performed, the process returns to step S26, and if it is determined that the action is not being performed, the process proceeds to step S29. . The action to be determined may be an action that continues from the action determined to have been performed in step S24, or may be an action that does not continue.

In step S29, the control unit 14 returns the display of the right image (FIG. 16B) in step S25 to the original display of the right image (FIG. 8B) in step S3. Further, the control unit 14 returns the display of the left image (FIG. 16A) in step S25 to the display of the original left image (FIG. 8A) in step S3. Thereafter, the process returns to step S24.

<Effect>
According to the navigation device 1 according to the second embodiment as described above, if it is determined that the action immediately before the left icon is operated or is being performed, the left icon is supported in the right image. The area is displayed in an identifiable manner, and the right icon corresponding area is displayed in the left image in an identifiable manner when it is determined that the action immediately before the right icon is operated or is being performed. . Thereby, the effect similar to Embodiment 1 can be acquired with respect to the user (passenger of a passenger seat) of a right seat, and the user (driver | operator) of a left seat.

If threshold value ZL1 <threshold value ZR1, right icon corresponding regions RA1 to RA5 are displayed earlier in the driver left image. As a result, the time until the operation on the driver's seat side can be made longer than that on the passenger's seat side, and the driver can be given a margin, which is convenient for the driver side.

Also in the second embodiment, the same modification as that of the first modification of the first embodiment may be applied. Specifically, the image displayed in the right icon corresponding area is not limited to the same image as the right icon, and any one of the first to sixth examples described below or a combination thereof is applied. May be.

As a first example, the control unit 14 performs a predetermined process such as a process for changing a color or brightness or a blurring process on the right icon, and an icon image obtained by the process is displayed on the right icon. It may be displayed in the corresponding area. As a second example, the control unit 14 assigns a color or brightness to the original image (background image) displayed in the right icon corresponding area in the left image, as in the modification shown in FIG. A predetermined process such as a process to be changed or a blur process may be performed, and an image obtained by the process may be displayed in the right icon corresponding region.

An image obtained by combining the right icon image may be displayed in the right icon corresponding area. As a fourth example, the control unit 14 may display an image of a predetermined graphic in the right icon corresponding area, as in the modification shown in FIG. As a fifth example, the control unit 14 obtains, for example, by combining an original image (background image) with a transmittance of 50% in a right icon corresponding region and a predetermined graphic image with a transmittance of 50%. The synthesized image may be displayed in the right icon corresponding area.

As a sixth example, similarly to the modification shown in FIG. 13B, the control unit 14, when there are a plurality of right icon corresponding regions, surrounds a plurality of right icon corresponding regions in the left image. May be displayed instead of the right icon corresponding area.

Even in the configuration as described above, the same effect as in the second embodiment can be obtained.

In the above description, the control unit 14 displays all the left icon corresponding areas LA1 to LA6 so as to be identifiable when it is determined that the action immediately before the left icon is operated or is being executed. I let you. However, the present invention is not limited to this, and the control unit 14 determines that at least one of the left icon corresponding areas LA1 to LA6 when it is determined that the action immediately before the left icon is operated or is being executed. One (for example, one left icon corresponding region closest to the indicator) may be displayed in an identifiable manner. Similarly, the control unit 14 determines that at least one of the right icon corresponding areas RA1 to RA5 (when it is determined that the action immediately before the right icon is operated or is being executed) ( For example, the right icon corresponding area closest to the indicator may be displayed in an identifiable manner. Further, not only the left icon corresponding areas LA1 to LA6 and the right icon corresponding areas RA1 to RA5 are displayed for any one of the icons, but also a predetermined distance from the position of the indicator such as (X, Y) coordinates. Alternatively, the left icon corresponding areas LA1 to LA6 and the right icon corresponding areas RA1 to RA5 located within a predetermined range including the position may be displayed.

<Embodiment 3>
Since the block configuration of the navigation device 1 according to the third embodiment of the present invention is the same as the block configuration of the first embodiment, the illustration thereof is omitted. And in the navigation apparatus 1 which concerns on this Embodiment 3, the same code | symbol is attached | subjected about what is the same as that of the component demonstrated in Embodiment 2, and it demonstrates centering on a different point below.

FIG. 17 is a flowchart showing the operation of the navigation device 1 according to the third embodiment. In the flowchart shown in FIG. 17, step S31 is added between steps S24 and S25 of the flowchart shown in FIG. 15, and steps S32 to S36 branching from step S25 are added to step S31. For this reason, steps S31 to S36 will be mainly described below. Further, the threshold value ZR1 may be a value different from the threshold value ZL1, but it is assumed here that the threshold value ZR1 is the same value in order to simplify the description.

In step S24 after step S3, the operation input processing unit 9 determines whether or not an action immediately before operating the left icon has been performed, and whether or not an action immediately before operating the right icon has been performed. Determine. If it is determined that the action immediately before the left icon is operated (act immediately before the right icon is operated), the process proceeds to step S31. If it is determined that the action is not performed, the process returns to step S24.

In step S31, the control unit 14 determines whether at least a part of the icon display area and at least a part of the icon corresponding area overlap. That is, on the screen of the split view display unit 2, the control unit 14 overlaps at least a part of the right icon display area and at least a part of the left icon corresponding area, and at least one of the left icon display areas. It is determined whether the part and at least a part of the right icon corresponding area overlap. If it is determined that they overlap, the process proceeds to step S32. If it is determined that they do not overlap, the process proceeds to step S25. Since operations in steps S25 to S29 are the same as those in the second embodiment, a description thereof will be omitted.

When the process proceeds from step S31 to step S32, in step S32, the control unit 14 determines that the left icon and the left icon are occupied based on the occupied area occupied by the plurality of left icons and the occupied area occupied by the plurality of right icons. Select one of the icons for the right that should be disabled. Here, the control unit 14 determines that one of the occupied area of the left icon and the occupied area of the right icon is greater than or equal to a predetermined ratio (for example, 50%) with respect to the screen area of the split view display unit 2. In addition, the operation for the one icon is enabled, and the operation for the other icon is disabled.

For example, it is assumed that the left image and the right image shown in FIGS. 18A and 18B are displayed on the split view display unit 2 in step S3. The left image in FIG. 18A includes left icons L11, L12, L13, L14, and L15 that are list buttons for displaying a list, and a left icon L16 that is a list scroll button for scrolling the list buttons. These are collectively referred to as “left icons L11 to L16”), and a left icon arrangement image for list display is displayed. Hereinafter, the left icon arrangement image for list display shown in FIG. 18A will be described as an example of an image in which the occupation area of a plurality of icons is relatively large. However, the present invention is not limited to this. The same applies to an icon arrangement image for use or an icon arrangement image for keyboard display. The right image in FIG. 18B is the same as the right image in FIG. 8B, and at least a part of the display area of the right icons R4 and R5 and at least a part of the display area of the left icon L15. However, they overlap each other on the screen of the split view display unit 2.

Here, in step S32, the total occupied area of the plurality of left icons L11 to L16 shown in FIG. 18A is greater than or equal to a predetermined ratio with respect to the screen area of the split view display unit 2. Assume that it has been judged. In this case, it is determined that the operation has been performed on the left icons L15 and the right icons R4 and R5 overlapping on the screen of the split view display unit 2 among the right icons R1 to R5 in FIG. Even if it is performed, the control unit 14 invalidates the operation. In step S32, the control unit 14 causes the split view display unit 2 to display the invalidation in an identifiable manner.

FIGS. 19A and 19B are diagrams showing display examples of the left image and the right image in step S32 of the navigation device 1 according to the third embodiment. Specifically, the control unit 14 Shows a display example when the operation on the right icons R4 and R5 is invalidated.

As shown in FIG. 19A, the control unit 14 displays the right icon corresponding areas RA1 to RA5 corresponding to the right icons R1 to R5 in the left image. Here, the control unit 14 preferentially displays the entire left icon L15 that has not been invalidated. As a result, in the right icon corresponding areas RA4 and RA5, a portion overlapping the left icon L15 is not displayed.

Further, as shown in FIG. 19B, similarly to the display example shown in FIG. 13B, the control unit 14 surrounds the left corresponding area corresponding to the left icons L11 to L16 in the right image. LE2 is displayed. Further, the control unit 14 displays the right icons R4 and R5 whose operations are invalidated in a darker color than the right icons R4 and R5 (FIG. 18B) in step S3, or invalidates the operations. It is displayed in a darker color than the right icons R1, R2, and R3 that are not displayed, or is displayed so as to be identifiable that the operation for the right icons R4 and R5 is invalidated by, for example, indicated by a broken line.

As described above, in step S32, when the control unit 14 determines that the occupied area of the plurality of left icons is equal to or greater than a predetermined ratio, the control unit 14 invalidates the operation on the right icon and disables the invalidation. Is displayed in an identifiable manner. On the other hand, in step S32, when the control unit 14 determines that the occupied area of the plurality of right icons is equal to or greater than a predetermined ratio, the control unit 14 invalidates the operation on the left icon as described above, The invalidation is displayed in an identifiable manner.

If the control unit 14 determines in step S32 that both the occupied area of the plurality of left icons and the occupied area of the plurality of right icons are greater than or equal to a predetermined ratio, the left icon In addition, the operation for one of the predetermined icons (for example, the icon on the passenger seat side) is invalidated, and the invalidation is displayed in an identifiable manner.

20 (a) and 20 (b) show another display example of the left image and the right image in step S32 of the navigation device 1 according to the third embodiment. In the left image in FIG. 20A, a left icon arrangement image for menu display in which left icons L21, L22, L23, L24, L25, and L26 are arranged is displayed. Again, the control unit 14 preferentially displays the left icons L23, L24, L25, and L26 that are not disabled. Further, as a result of the control unit 14 determining that the occupied area of the left icons L21, L22, L23, L24, L25, and L26 is large, as shown in FIG. 20B, the right icons R1, R2, R3, It is displayed in an identifiable manner that the operation for any of R4 and R5 is invalidated.

In step S33 of FIG. 17, the operation input processing unit 9 determines whether an operation has been performed on a valid icon (an icon that has not been invalidated). If it is determined that an operation for a valid icon has been performed, the process proceeds to step S34. If it is determined that an operation has not been performed, the process proceeds to step S35.

In step S34, the control unit 14 executes the function of the application corresponding to the operated icon, similarly to step S27. Thereafter, the process proceeds to step S35. When the icon arrangement image is associated with the operated icon in advance and stored in the storage unit 11, the process returns from step S34 to step S3, and the icon arrangement image is displayed in the split view display unit 2. May be displayed.

In step S35, as in step S28, the operation input processing unit 9 determines whether or not the action immediately before operating the left icon is being performed, and the action immediately before operating the right icon is performed. It is determined whether it is in the middle. If it is determined that the action immediately before operating the left icon (act immediately before operating the right icon) is being performed, the process returns to step S33, and if it is determined that the action is not being performed, the process proceeds to step S36. .

In step S36, the control unit 14 returns from the display of the right image (FIG. 19B) in step S32 to the display of the original right image (FIG. 18B) in step S3. Further, the control unit 14 returns the display of the left image (FIG. 19A) in step S32 to the display of the original left image (FIG. 18A) in step S3. Thereafter, the process returns to step S24.

<Effect>
According to the navigation device 1 according to the third embodiment as described above, on the screen of the split view display unit 2, at least a part of the right icon display area and at least a part of the left icon corresponding area overlap. In addition, when at least a part of the left icon display area and at least a part of the right icon corresponding area overlap, the operation for one of the left icon and the right icon is invalidated and invalidated. Is displayed on the split view display unit 2 in an identifiable manner. Accordingly, it is possible to prevent the left seat user from operating the right icon unintentionally or the right seat user from operating the left icon unintentionally.

Further, according to the third embodiment, based on the occupied area of the plurality of left icons and the occupied area of the plurality of right icons, one of the left icon and the right icon to be invalidated is selected. To do. Thereby, the icon which should invalidate operation can be selected appropriately.

Further, as in the third embodiment, only the operation for the other icon (for example, the right icons R4 and R5 described above) that overlaps with one icon is invalidated, and the other icon that does not overlap with one icon. If the operation for the right icons R1, R2, and R3 (for example, the above-described right icons) is not invalidated, the operation restrictions can be kept to the minimum necessary.

<Modification of Embodiment 3>
When only one left icon and one right icon are displayed, the control unit 14 determines the left icon and the right icon based on the occupied area of one left icon and the occupied area of one right icon. One of the operations that should be disabled may be selected. Further, generally speaking, the control unit 14 occupies one left icon or a plurality of left icons, and one right icon or a plurality of right icons. Based on the area, one of the left icon and the right icon that should be disabled may be selected.

In the above description, the control unit 14 enables the operation for the one icon when either the occupied area of the left icon or the occupied area of the right icon is equal to or higher than a predetermined ratio. The operation for the other icon was disabled. However, the present invention is not limited to this, and the control unit 14 compares the occupied area of the plurality of left icons with the occupied area of the plurality of right icons, enables the operation for one icon having a large occupied area, and You may invalidate operation with respect to the other icon with a small area.

In the above description, the operation for one of the left icon and the right icon is disabled in step S32 after step S24 and step S31. However, the present invention is not limited to this, and step S31 and step S32 may be performed before step S24.

<Embodiment 4>
Since the block configuration of the navigation device 1 according to the fourth embodiment of the present invention is the same as the block configuration of the first embodiment, the illustration thereof is omitted. And in the navigation apparatus 1 which concerns on this Embodiment 4, the same code | symbol is attached | subjected about what is the same as or similar to the component demonstrated in Embodiment 1, and it demonstrates centering around a different point below.

21 and 22 are diagrams showing display examples of the right image of the navigation device 1 according to the fourth embodiment. The images shown in FIGS. 21 and 22 are the same as the images shown in FIGS. 8B and 9B, respectively.

In the fourth embodiment, the control unit 14 determines whether the right image is displayed according to the distance Z between the indicator and the detection surface of the touch panel 3 while the action immediately before the left icon is operated. Display control (first control) for displaying the left icon corresponding area in an identifiable manner and non-display control (second control) for not displaying the left icon corresponding area in the right image so as to be distinguishable are selectively executed. It is configured.

For example, when the distance Z is greater than the threshold value ZL1 (Z> ZL1), the operation input processing unit 9 determines that the action immediately before operating the left icon has not been performed. In this case, as in the first embodiment, the control unit 14 according to the fourth embodiment displays a right image in which the left icon corresponding region cannot be identified, as shown in FIG.

When the distance Z is equal to or smaller than the threshold value ZL1 and larger than the threshold value ZL2 (ZL2 <Z ≦ ZL1), the operation input processing unit 9 determines that an action immediately before operating the left icon is performed. In this case, the control unit 14 according to the fourth embodiment performs display control according to the distance Z. As a result, the control unit 14 displays the same images as the left icons L1 to L6 on the left image as the left icon corresponding areas LA1 to LA6 as shown in FIG. 22 as in the first embodiment.

When the distance Z is equal to or less than the threshold value ZL2 and greater than 0 (0 <Z ≦ ZL2), the operation input processing unit 9 determines that the action immediately before the left icon is operated. In this case, the control unit 14 according to the fourth embodiment performs non-display control according to the distance Z. As a result, unlike the first embodiment, the control unit 14 displays an image in which the left icon corresponding region cannot be identified, as shown in FIG.

<Effect>
According to the navigation device 1 according to the fourth embodiment as described above, display control and non-display control are selectively performed according to the distance Z while the action immediately before the left icon is operated. To run. According to such a configuration, when the indicator of the user in the right seat (passenger in the passenger seat) approaches the touch panel 3 from a position where the possibility of unintentionally operating the left icon is sufficiently low It is possible to hide the left icon corresponding area so that the visibility of the right image is enhanced.

<Modification 1 of Embodiment 4>
When the distance Z is equal to or smaller than the threshold value ZL1 and greater than the threshold value ZL3 (ZL2 <ZL3 <Z ≦ ZL1), the control unit 14 corresponds to, for example, a left icon as in the display example illustrated in FIG. An image obtained by combining the original image (background image) of the region with a transmittance of 50% and the right icon image with the transmittance of 50% may be displayed in the left icon corresponding region. When the distance Z is equal to or smaller than the threshold value ZL3 and larger than the threshold value ZL2 (ZL2 <Z ≦ ZL3), the control unit 14 displays the same images as the left icons L1 to L6 as shown in FIG. The corresponding areas LA1 to LA6 may be displayed.

Further, in the configuration in which the composite image obtained from the original image and the icon image is displayed in the left icon corresponding region, the transmittance of the original image and the transmittance of the icon image in the composite image are gradually changed according to the distance Z. It may be changed to. When configured in this way, the transition of the right image from the state in which the left icon image is not displayed in the left icon corresponding area to the state in which the left icon image is displayed in the left icon corresponding area Alternatively, the reverse transition can be performed gradually. As a method of gradually changing the transmittance according to the distance Z, for example, a function (E = f1 (Z)) of the transmittance E and the distance Z is stored in the storage unit 11, and the control unit 14 May be configured to change the transmittance by using the function.

In the above description, the control unit 14 selectively executes display control and non-display control according to the distance Z in the right image. However, the present invention is not limited to this, and the control unit 14 selectively executes display control and non-display control according to the distance Z in the left image or the right image and the left image as described above. May be. That is, when the distance Z is equal to or less than the threshold value ZR1 and greater than the threshold value ZR2 (ZR2 <Z ≦ ZR1), the control unit 14 performs display control for the left image as in the display example of FIG. When it is greater than 0 and less than or equal to the threshold value ZR2 (0 <Z ≦ ZR2), non-display control may be performed on the left image as in the display example of FIG.

Moreover, as described above, the threshold value ZL1 and the threshold value ZR1 may be the same value or different values. Similarly, the threshold value ZL2 and the threshold value ZR2 may be the same value or different values.

Further, the control unit 14 may change the threshold value ZL1 and the threshold value ZL2 according to the type of application being executed on the left image side or the function executed when the left icon is operated. For example, when the left icon is a special icon that requires attention, the threshold icon ZL1 is increased so that the left icon corresponding area can be displayed in the right image so that it can be identified from an early stage of the operation. Can be made. As a result, the right seat user can recognize from the early stage that a special left icon is displayed in the left image, and as a result, the user may operate the left icon unintentionally. Can be further reduced. Similarly, the control unit 14 changes the threshold value ZR1 and the threshold value ZR2 in accordance with the type of application being executed on the right image side or the function executed when the right icon is operated. It may be configured.

<Modification 2 of Embodiment 4>
In the above-described configuration in which a signal indicating the three-dimensional position of the indicator is periodically output from the touch panel 3, the control unit 14 can calculate the moving speed v of the indicator based on the signal. . As described above, in the configuration in which the output signal from the touch panel 3 includes the signal related to the moving speed v of the indicator, the control unit 14 moves the moving speed while the action immediately before the left icon is operated. Depending on v, display control (first control) and non-display control (second control) may be selectively executed.

According to such a navigation device 1 according to the second modification, for example, the indicator moves at a predetermined moving speed (for example, a moving speed when the operation is unclear, calculated from past statistics). When moving in v1), display control or non-display control can be performed.

The control unit 14 may perform the above-described display control immediately after it is determined that the indicator is moving at a predetermined moving speed v1, or a certain time has elapsed from the time when the determination is made. The above display control may be performed later. Similarly, the control unit 14 may perform the above-described non-display control immediately after it is determined that the indicator is moving at a predetermined moving speed v1, or for a certain period of time from the time of the determination. The non-display control described above may be performed after elapses.

Further, the configuration of the second modification and the configuration of the first modification of the fourth embodiment may be combined. For example, the control unit 14 may gradually change the transmittance of the original image and the transmittance of the icon image in the composite image according to the moving speed v. As a method of gradually changing the transmittance according to the moving speed v, for example, a function (E = f2 (v)) of the transmittance E and the moving speed v is stored in the storage unit 11 and controlled. What is necessary is just to comprise the part 14 so that the transmittance | permeability may be changed by using the said function.

Here, as the moving speed v, a moving speed related to any one to three of the XYZ coordinate axes may be used. For example, only the movement speed of the Z coordinate axis may be used, or the movement speed of the X coordinate axis and the Y coordinate axis (movement speed in the XY plane) may be used. Further, the user may be configured to be able to set which of the XYZ coordinate axes to use for the moving speed. According to such a configuration, usability can be improved.

<Other variations>
In the above description, the configuration in which the touch panel 3 is applied as the input unit has been described. However, the input unit is not limited to the touch panel 3 as long as it can uniformly accept an operation on the left image for executing the function of the application and an operation on the right image for executing the function of the application. is not. For example, a touch pad provided apart from the split view display unit 2 may be applied to the input unit. At this time, the touch pad has a function of obtaining the three-dimensional position of the indicator, the position of the indicator on the operation area of the touch pad is associated with the display area of the split view display unit 2, and the indicator You may perform by the point and icon display which show the position of.

<Modification in which the display control device is applied to devices other than the navigation device>
