Description

  The present invention relates to a user interface technology in an in-vehicle system mounted on an automobile.

  As a user interface technology in an in-vehicle system mounted on an automobile, a navigation device that displays a map or a route on a display device, the user's operation is performed so as not to disturb the user's concentration on driving operation while the vehicle is running. A technique for prohibiting acceptance is known (for example, Patent Document 1).

On the other hand, as a display device that can be used in such an in-vehicle system, a display device that can display two images so that different images are visually recognized from two different directions is also known (for example, Patent Document 2). .
Here, FIG. 6d schematically shows the structure of a liquid crystal display device capable of displaying two images so that different images are viewed from two different directions.
As shown in the figure, this liquid crystal display device has a liquid crystal display panel 601 such as a TFT liquid crystal panel for displaying an image, a parallax barrier 602 using a patterned phase difference plate, and the like, enabling / disabling the effect of the parallax barrier. A switching liquid crystal layer 603 to be switched and a backlight light source 604 are provided.

  When the effect of the parallax barrier 602 is made effective by the switching liquid crystal layer 603, the field of view of the pixel of the display panel 601 is alternately different in the horizontal direction as illustrated. Therefore, by displaying the image b in which the pixels of the image a1 and the pixels of the image a2 are alternately arranged in the horizontal direction on the liquid crystal display panel 601 as shown in c, as shown in e1 and e2, the liquid crystal display device is displayed. Thus, only the a1 image is visually recognized by the user in the first direction, and only the a2 image is visually recognized by the user in the second direction with respect to the liquid crystal display device.

On the other hand, if the effect of the parallax barrier 602 is disabled by the switching liquid crystal layer 603, it is possible to use all the pixels of the liquid crystal display device for displaying one image as in the case of a normal liquid crystal display device.

  Each of the on-vehicle systems described above may be a navigation system that generates at least a navigation image representing a current position on a map as the information providing image in the information providing image generating unit.

  As described above, according to the present invention, in an in-vehicle system provided with a display device, a driver other than the driver is allowed to operate the in-vehicle system, and a driver's hindrance is caused by a change in display content of the display device due to the operation. Can be suppressed.

Hereinafter, an embodiment of the present invention will be described taking application to a navigation device mounted on an automobile as an example.
FIG. 1 shows a configuration of a navigation device according to the present embodiment.
As illustrated, the navigation device 100 includes a control device 1, a display device 2, an operation unit 3, an operator detection sensor 4, a GPS receiver 5, and a vehicle state sensor 6. Here, the vehicle state sensor 6 is a sensor group that detects a vehicle state such as an orientation sensor, a vehicle speed sensor, and a stop detection sensor. The stop detection sensor may be, for example, a sensor that detects the stop of the vehicle when the position of the handbrake is at the braking position and the vehicle speed detected by the vehicle speed sensor is zero.

  Here, the display device 2 can display two images having two different viewing angles by using pixels for alternately displaying two images in the horizontal direction as shown in FIG. This is a display device 2 that can display one image having one viewing angle by using these pixels for displaying one image. When the double view mode is set from the control device 1, the display device 2 performs display operations of two images having two different viewing angles. When the single view mode is set from the control device 1, The display operation of one image having one viewing angle is performed. Here, the two viewing angles in the double view mode are the viewing angle at which only the driver seat user of the driver seat and the passenger seat can view one of the two images, and the driver seat and the passenger seat. Of these users, only the passenger seat user can view the other image of the two images. In addition, one viewing angle in the single view mode is a viewing angle at which both the driver's seat and the passenger seat can visually recognize an image.

  As shown in FIG. 2, the display device 2 is disposed, for example, between a driver seat and a passenger seat, and is shared by a driver seat user and a passenger seat user. As illustrated, the operation unit 3 is also disposed between the driver seat and the passenger seat, and is shared by the driver seat user and the passenger seat user. As shown in the figure, the operator detection sensor 4 is a sensor that detects the approach of the operator's hand to the operation unit 3, and the approach of the operator's hand from the left and the operator's hand from the right Detects approach of each hand, (in the case of a right-hand drive car) detects the approach of the hand from the left, detects the passenger in the passenger seat as the operator, and operates if it detects the approach of the hand from the right A user who is a driver is detected as a driver. In addition, as such an operator detection sensor 4, the two proximity sensors arrange | positioned at the right and left of the operation part 3 using an ultrasonic wave, infrared rays, etc. can be used.

  Returning to FIG. 1, the control device 1 includes a current state calculation unit 11, a route search unit 12, a map data storage unit 13 that is a storage device such as a DVD drive or HDD that stores map data representing a map, a memory 14, and a control unit. 15, a guide image generation unit 16, a GUI control unit 17 that provides a user with a GUI using the operation unit 3 and the display device 2, and a display controller 18 that controls display of the display device 2.

  However, each unit other than the display controller 18, the memory 14, and the map data storage unit 13 of the control device 1 described above is hardware-related, such as a microprocessor, the memory 14, other graphic processors, geometric processors, and the like. A CPU circuit having a general configuration having a device may be used. In this case, each unit of the control device 1 described above is realized as a process realized by a microprocessor executing a program prepared in advance. It may be done. In this case, such a program may be provided to the control device 1 via a recording medium or an appropriate communication path.

  In such a configuration, the current state calculation unit 11 of the control device 1 reads the map data read from the map data storage unit 13 with respect to the current position estimated from the outputs of the vehicle state sensor 6 and the GPS receiver 5. Performs map matching processing with the map around the current position that was previously determined, and calculates the most likely coordinates as the current position and the most likely direction as the current traveling direction. The traveling direction is determined and set in the memory 14.

In addition, the control unit 15 receives a destination setting from the user via the operation unit 3 and the GUI control unit 17 and sets the destination setting in the memory 14.
Then, when receiving the destination setting, the control unit 15 causes the route search unit 12 to search for a recommended route to the destination. The route search unit 12 reads out map data of a necessary geographical range from the map data storage unit 13, and sets a minimum cost route from the current position to the destination set in the memory 14 to a predetermined cost model such as a minimum distance. As a recommended route, the calculated recommended route is set in the memory 14. In addition, when the current position set in the memory 14 becomes near the destination, the control unit 15 determines that the destination has arrived, and also performs a process of clearing the destination and the recommended route set in the memory 14. .

  Then, the guide image generation unit 16 obtains the map image of the map display range calculated by the control unit 15 according to the current position set in the memory 14 or the point designated by the user and the map display scale set at that time. Drawing is performed based on the map data stored in the map data storage unit 13. Further, a guide image is generated on the drawn map image in which a graphic representing the current position, recommended route, and destination set in the memory 14 is drawn.

Hereinafter, user interface control processing performed by the control unit 15 will be described.
FIG. 3 shows the procedure of this user interface control process. The user interface control process starts when the navigation device 100 is activated.
As shown in the drawing, in the user interface control process, first, the single view mode is set in the display device 2 via the display controller 18 (step 302). As described above, when the single view mode is set, the display device 2 performs a display operation of one image that is visually recognized by both the driver seat and the passenger seat user.

Next, the control unit 15 starts displaying the navigation window on the display device 2 via the GUI control unit 17 and the display controller 18 (step 304).
Here, FIG. 4 a shows a display example of the display screen of the display device 2 displaying the navigation window. As shown in the figure, the navigation window 40 is displayed on the entire surface of the display device 2, and a guidance image display area 400 and a guidance information display area 410 are provided in the navigation window 40.

  The guide image 401 generated by the guide image generation unit 16 is displayed in the guide image display area 400. Here, in the guide image 401, a current position mark 402 representing the current position, a destination mark 403 representing the destination, and a route graphic 404 representing the recommended route are represented on a map image around the current position. It has become.

In the guidance information display area 410, various route guidance information such as the traveling direction, the scale of the guidance image 401, the required time to reach the destination, the required journey distance, and the current time are displayed.
Returning to FIG. 3, when the navigation window 40 is displayed (step 304), occurrence of a user operation in the operation unit 3 is monitored (step 306). Then, if a user operation occurs, it is checked whether the generated user operation is an operation permitted to the driver user regardless of whether the vehicle is traveling (step 308). Here, in this embodiment, the operation permitted to the user who is a driver regardless of whether the vehicle is running is an operation that does not display a menu according to the operation, for example, an operation for changing the map scale of the guide image 401 And so on.

  Then, if the generated user operation is an operation permitted by a user who is a driver regardless of whether the vehicle is running, the process of the control unit 15 corresponding to the user operation is started and executed (step 326), the process returns to step 306 to wait for the next user operation to occur. That is, for example, if the generated user operation is a map scale reduction operation (wide area display operation) of the guide image 401, the display scale set in the guide image generation unit 16 is decreased by one step, and the process returns to step 306.

  On the other hand, if the generated user operation is not an operation permitted to the user who is a driver regardless of whether the vehicle is traveling, the stop detection sensor of the vehicle state sensor 6 is connected to the vehicle through the current state calculation unit 11. It is checked whether or not a stop is detected (step 310). If a stop is detected, for example, as shown in FIG. 4 b, a menu window 420 representing a menu corresponding to the generated user operation is displayed on the display device 2 via the GUI control unit 17 and the display controller 18. The menu window 420 is displayed so as to be superimposed on the navigation window 40 (step 328), the menu operation via the user operation unit 3 is accepted (step 330), the menu window 420 is closed, and the received menu operation is accepted. The process of the control unit 15 is started and executed according to (step 332), and the process returns to step 306 to wait for the next user operation. That is, for example, if the generated operation is a main menu call operation, as shown in FIG. 4B, a destination setting menu item for receiving a call for destination setting processing or a call instruction for searching for the nearest facility is received. A main menu representing the nearest facility menu item and various setting menu items that accept calls of various setting processes of the navigation device 100 is displayed. For example, if the destination setting menu item is selected via the operation unit 3, the destination setting process is activated to accept the destination setting or change. In addition, in the setting process of the activated destination, the setting and change of the destination are accepted while displaying a predetermined destination setting acceptance window on the display device 2, and the setting is completed. If so, the displayed window is closed and the process is terminated.

  Returning to FIG. 3, if no stop is detected in step 310, it is checked whether the operator detection sensor 4 has detected a user who is a driver as an operator (step 312). When the user who is the driver is detected, the process returns to step 306 and waits for the next user operation. That is, in this case, the generated user operation is not accepted.

  On the other hand, when the author detection sensor does not detect a user who is a driver as an operator, that is, when a user at the front passenger seat is detected as an operator (step 312), the display controller 18 is used. Then, the double view mode is set in the display device 2 (step 314). As described above, when the double view mode is set, the display device 2 performs the display operation of two images, that is, an image that is visible only to the passenger seat user and an image that is visible only to the driver seat user. Do. Here, in the double view mode, the display device 2 displays one image that is visible only to the driver's seat user, and one display device that displays an image that is visible only to the passenger seat user. These two display devices can be virtually captured. Therefore, in the following, for convenience, a virtual display device that displays an image that is visible only to the driver's seat user is referred to as a “driver's seat virtual display device”, and an image that is visible only to the passenger seat user is displayed. This virtual display device is referred to as a “passenger seat virtual display device”.

  If the double view mode has been set (step 314), display of the navigation window 40 is started on the driver seat virtual display device via the GUI control unit 17 and the display controller 18 (step 316). ), The display of the navigation window 40 on the passenger seat virtual display device is started (step 318). In addition, the navigation window 40 displayed on the driver's seat virtual display device in step 316 and the navigation window 40 displayed on the passenger seat virtual display device in step 318 have the same contents as the navigation window 40 started to display in step 304. It has something. However, the navigation window 40 that starts display in steps 316 and 318 has a horizontal pixel count (resolution) that is half the horizontal pixel count of the navigation window 40 that started display in step 304. The pixels are thinned out.

  Next, the control unit 15 displays a menu window 420 representing a menu corresponding to the generated user operation only on the passenger seat virtual display device on the navigation window 40 displayed on the passenger seat virtual display device. The window 420 is displayed so as to be superimposed (step 320), the menu operation through the user's operation unit 3 is accepted (step 322), the menu window 420 is closed, and the processing of the control unit 15 according to the accepted menu operation Is started and executed (step 324), and the process returns to the process from the first step 302. Here, the process activated in step 324 is displayed only on the passenger seat virtual display device when the window used in the process is displayed. In step 322, the menu operation via the user operation unit 3 may be accepted only when the operator detection sensor 4 detects the passenger in the front passenger seat as the operator.

  As a result of displaying the menu window 420 and the window used in the process activated in response to the menu operation only on the passenger seat virtual display device as described above, the user of the passenger seat can respond to the operation while the vehicle is traveling. When an operation for displaying a menu occurs, the display of the display device 2 is as shown in FIGS.

4c shows the display screen of the passenger seat virtual display device, that is, the display screen of the display device 2 visually recognized by the passenger at the passenger seat, and FIG. 4d shows the display screen of the driver seat virtual display device, ie, The display screen of the display apparatus 2 visually recognized from the user of a driver's seat is represented.
As shown in FIG. 4, when an operation that causes a menu to be displayed in response to an operation by the user at the passenger seat occurs while the vehicle is traveling, only the user at the passenger seat is visually recognized as shown in FIG. 4C. As shown, the menu window 420 and other windows are displayed on the display device 2. On the other hand, as shown in FIG. 4d, for the user who is a driver, the display device 2 is displayed so that only the navigation window 40 remains visible. Therefore, it is possible to prevent the driver from obstructing the display of a menu or the like corresponding to the operation of the passenger seat user while allowing the operation of the passenger seat user.

The user interface control process performed by the control unit 15 has been described above.
According to the above user interface control processing, the navigation window 40 and the menu window with high image quality are provided in the single view mode, except for the case where a menu or the like is displayed according to the operation of the passenger at the passenger seat while the vehicle is traveling. Various displays such as 420 will be performed.

  By the way, in the above user interface control processing, step 312 may be eliminated, and if it is determined in step 310 that the vehicle is stopped, the process may proceed to step 316 as it is. Even in this case, the menu window 420 displayed in step 320 cannot be visually recognized by the user who is the driver, and hence the subsequent operation cannot be performed. As a result, the driving of the user who is the driver Operations that are not allowed to the inside driver will be prohibited.

The embodiment of the present invention has been described above.
By the way, in the above embodiment, only when the operation of the passenger in the passenger seat that is not permitted by the driver occurs during the traveling, the display device receives the operation of the passenger in the passenger seat or completes the received processing. Although the double view mode is set to 2, the double view mode may be set to the display device 2 at all times while the vehicle is traveling.

In this case, display on the display device 2 may be performed as follows.
That is, when the vehicle is stopped, the single view mode is set on the display device 2 and is superimposed on the navigation window 40 as shown in FIG. 5a to display various command buttons 501 for accepting user operations. Further, while traveling, the passenger's seat virtual display device displays various command buttons 501 similar to those when the vehicle is stopped, superimposed on the navigation window 40, as shown in FIG. As shown in FIG. 5 c, only the command button 501 that accepts an operation that is allowed for the traveling driver is displayed so as to be superimposed on the navigation window 40. Further, when the menu window 420 and other windows are displayed in response to an operation that is not permitted by the driving driver, these windows are displayed only on the passenger seat virtual display device. The operation of the passenger in the passenger seat is accepted, and the command button displayed on the driver seat virtual display device is erased until the operation is accepted or the accepted processing is completed.

In the case of controlling the user interface as shown in FIG. 5, it is preferable to use a transparent touch panel arranged on the display screen of the display device 2 as the operation unit 3.
Moreover, the above embodiment is good also as what always uses the display apparatus 2 in double view mode. In this case, the display of FIG. 4a, FIG. 4b, or FIG. 5a performed in the single view mode in the above embodiment is applied to both the driver seat virtual display device and the passenger seat virtual display. To do.

  In the above description, the application to the navigation device has been described as an example. However, the user interface control technology according to the present embodiment is a vehicle-mounted video that displays a video received by TV broadcasting or a video reproduced by a DVD video playback device. The present invention can be similarly applied to control of user interfaces of various in-vehicle systems such as systems. That is, for example, when applied to an in-vehicle video system, the above-described embodiment may be applied in place of the navigation window 40 as a window for displaying video.
