  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
A vehicle-mounted information display device 1 shown in FIG. 1 is a vehicle-mounted device serving as an information terminal mounted on a vehicle, and includes a display / input unit 3 that constitutes a touch panel having both a display function and an input function, and a network such as the Internet. And a communication means 5 for communicating information via the. The communication means 5 is used to download information such as news and application update information via the network, and display necessary information on the display / input means 3 serving as display means.

  The in-vehicle information display apparatus 1 includes an information storage unit 7 including an information holding unit, an output control unit 9 including a display control unit, a user input information determination unit 11, an input information processing unit 13, and an information re-presentation. And means 15.

  The information storage unit 7 acquires information via the network using the communication unit 5 and stores the acquired information. The output control means 9 controls which information is displayed on the display / input means 5 from the information stored in the information storage means 7.

  The user input information determination unit 11 continues to display information on the display / input unit 3 when the input operation of the occupant on the touch panel screen of the information displayed on the display / input unit 3 is displayed. It is then determined whether to display the details, or whether to re-present the information to the user after the displayed time. That is, the user input information determination unit 11 constitutes an information re-presentation determination unit.

  Specifically, the user input information determination unit 11 holds a list of input methods for the user's touch panel, and compares the user's input method in the input method list with the actual input method for the touch panel for determination. To do. The input method of the user in the input method list is, for example, a flick operation or a drag and drop operation via the touch panel for information displayed on the touch panel. When these flick operations or drag and drop operations are performed, the information re-presentation means 15 causes the information storage means 7 to temporarily hold the information displayed on the display / input means 3 (touch panel).

  The input information processing means 13 displays the details on the display / input means 3 when the user input information judgment means 11 determines that the information display on the display / input means 3 will continue to be displayed in detail when it is displayed. The information to be processed is processed and displayed on the display / input means 3 via the output control means 9.

  When the user input information determination unit 11 determines that the information is to be re-presented to the user after the displayed time, the information re-presentation unit 15 temporarily holds the information in the information storage unit 7 and then the information Is displayed on the display / input unit 3 by the output control unit 9.

  When the information re-presentation determination means (user input information determination means 11) determines that the display on the touch panel is to be continued by the input information processing means 13 and the information re-presentation means 15, the information is continuously displayed on the touch panel. When the information re-presentation determining means determines that the information is to be re-presented to the user after the displayed time point, the information re-presenting means constitutes a control means for temporarily holding the information in the information holding means so that the information is re-presented to the user.

  The on-vehicle information display device 1 includes a navigation device. The navigation device causes the display / input unit 3 to display the information in the map database 17 in accordance with the information of the position measuring unit 21 such as GPS for the navigation display control unit 19 to measure the position of the vehicle. In addition, by registering a location (position) on a map such as a home or a frequently visited location in the location registration means 23 in advance, the registered location is set as a destination or a transit point when the vehicle moves. can do.

  Next, the processing procedure of the information display method by the vehicle-mounted information display device 1 will be described based on the flowchart of FIG. First, it is determined whether or not there has been a user input operation on the display / input means 3 (step 201). When it is determined that there is no input (NO in step 201), the user input operation is awaited. The judgment that there is no input operation is made when there is no input operation even if a predetermined time elapses in the measurement by the timer. If it is determined that there is an input (YES in step 201), the input target information is selected (extracted) (step 202).

  Thereafter, the user input information determination means 11 continues to display details on the touch panel at the time when the information is displayed on the touch panel, or re-presents the information to the user after the displayed time. It is determined whether or not to perform (step 203).

  Here, the processing in step 203 is processing for determining whether or not the input operation in step 201 is a specific input method such as a flick operation or a drag-and-drop operation in the input method list described above. .

  If it is not a specific input operation, that is, if it is determined that the touch input operation is a normal touch input operation, it is determined that re-presentation of information is unnecessary (NO in step 203). The displayed object information is continuously displayed in detail on the display / input means 3 (touch panel) (step 204). Thereby, the user can see detailed information via the display / input means 3.

  On the other hand, if it is determined that the input operation on the touch panel is not a normal touch input operation but a specific input method, it is determined that re-presentation of information is necessary (YES in step 203), and the information In order to re-present the information, the information is temporarily stored in the information storage means 7 (step 205).

  In the next step 206, the information re-presentation means 15 determines whether or not the re-presentation condition is satisfied. For example, when the specific input method is a drag-and-drop operation, when the drag-and-drop operation is performed so that information is positioned at a specific position on the travel route set by the navigation device, Whether the vehicle has reached a specific position. That is, when the vehicle reaches a specific position, the information is re-presented on the display / input unit 3.

  If it is determined that the condition for re-presentation is satisfied (YES in step 206), information is displayed (re-presented) on the display / input means 3 (step 207).

  As described above, in the present embodiment, whether the displayed information is continuously displayed in detail as it is, or is re-presented at a place specified by the user and the information is viewed later, depending on the input operation method on the touch panel 3 of the user. Can be selected. As a result, the user can freely select the time and place where he / she wants to see the information, and the user is not particularly concerned about the displayed information. Even when the information cannot be sufficiently viewed, it is possible to suppress oversight of the information and to enhance the convenience as an in-vehicle information display device.

  Next, an example of a case where it is determined in the process of step 203 that information is re-presented by performing a flick operation or a drag-and-drop operation on the touch panel will be described.

  3A and 3B are image diagrams of the touch panel (display / input unit 3). FIG. 3A shows a state before the operation, and FIG. 3B shows a state after the operation. (A) and (b) are two-screen displays, respectively, the left area G1 is an application display, and various information headings A (in this case, nine types) are displayed, and the right area G2 is a map display. It has become.

  As shown in FIG. 3 (b), information desired to be viewed by the user out of the heading A of the information displayed in FIG. 3 (a) is selected with a finger and moved to a specific position on the map by a flick operation or a drag-and-drop operation. Transfer and register.

  The flick operation is an operation for selecting target information on the touch panel screen and skipping it to another position on the screen. When a flick operation is performed, a flick length (flick amount) and a flick angle (in which direction information is transferred) when the user performs a flick input are calculated. When the calculation result of the flick length and the flick angle is obtained, an optimum transmission destination is selected based on the calculated flick length and flick angle from the locations registered in advance in the position registration means 23 of the navigation device. .

  Here, when the target transmission destination is registered in the position registration means 23, the communication means 5 is used to send information requested to be re-presented to a delivery destination registered in advance by the user, for example, a home or office PC. To send automatically.

  When the target transmission destination is not registered in the position registration means 23, or when the optimal transmission destination cannot be obtained because the flick length and the flick angle are too short with respect to the registered location, the user is requested to input again. Request. For example, a message “Please input again” may be displayed on the display / input means 3 or guidance may be provided using voice. After the guidance, the user requests the flick input again.

  When performing a flick operation, the user can intuitively understand what is in which direction by looking at the map. For example, when the home is on the east side of the map center and the company is on the south side, the user knows this intuitively. In addition, if the home scale icon is presented on the east side and the company icon is presented on the south side by changing the map scale, it can be understood more directly.

  If a map is displayed in bird view, it can be intuitively understood that there is a cloud (cloud) in the upward direction on the map, and it is possible to imagine a “cloud” on the Internet line.

  Therefore, the information transfer destination is registered to the home for the flick operation in the east direction, to the company for the flick operation in the south direction, and to the cloud, that is, the server on the network, for the flick operation in the upward direction. By doing so, the selected information (information that you want to see later) can be intuitively transferred to a place that you want to see later (home, office, or cloud) depending on in which direction the user flicks. That is, when information is re-presented, the information is temporarily stored in the home or company PC or a server on the network.

  FIG. 4 shows a registered place list on the map registered in the position registration means 23. Address information of the transfer destination such as home, company, cloud, etc. is stored in advance in the same list as the registered location on the map. This information may be registered inside the vehicle, or may be registered outside the vehicle, for example, by remote operation on a home PC.

  When a flick operation is performed in the registered state as described above, a transfer destination corresponding to the direction and amount of the flick can be selected. If there are registered locations that include multiple forwarding destinations in the east or south direction, the distance and angle may be calculated from the flick amount and flick angle, and the optimal registered location may be selected. Then, an optimal transfer destination may be selected by asking the user. Then, the information is automatically transferred to the selected transfer destination. Note that information may be transferred simultaneously to a plurality of transfer destinations with a plurality of transfer destinations remaining. By transferring in this way, the details of the information can be re-presented at the transfer destination terminal device, and the convenience of the user is improved.

  In particular, by transferring information to a server (cloud) on the network, the user can view the information from a plurality of places where the server can be accessed, such as a company or home, and the convenience is further improved.

  Even when the drag and drop operation is performed in FIG. 3B, the transfer destination can be intuitively recognized and operated in the same manner as the flick operation described above.

  In addition, when the heading A of the information is dragged and dropped onto the route to the set destination on the map by the navigation device, the selected information is re-presented on the touch panel when the vehicle arrives at the location. Can do. As a result, the user can view details of information at a desired position on the guidance route by the navigation device.

  Thus, according to the in-vehicle information display device 1 of the present embodiment, a user request to re-present information details later is input by a drag-and-drop operation or a flick operation performed with a finger on the touch panel 3. Therefore, it is possible to reflect the user's will with a simple operation that does not hinder driving.

  In addition, a location where information is re-presented can be selected from a location registered in advance in an area on the map or a location associated in advance with the direction of the map. For example, when there is a home in a certain area on the map and a company in another certain area, each of these areas is registered in advance as a home area or a company area.

  By doing so, it is possible to automatically transfer the information to the address of the home PC by dragging and dropping the heading A of the information to the home area, so that the details of the selected information can be viewed at home at a later time. Can be. Also, by dragging and dropping the information heading A to the company area, the information can be automatically transferred to the address of the company's PC, and the details of the selected information will be viewed at the company at a later time. Can do.

  Also, by registering another area as your smartphone area and dragging and dropping the heading A to that area, you can automatically transfer information to your smartphone address, The details of the selected information can be viewed on the smartphone.

  Alternatively, by flicking the heading A in a certain direction on the map or outside the map, the details of the selected information can be viewed at a location that is associated with the direction and amount of the flick in advance. In this way, the location of re-presentation of information can be easily specified simply by dragging and dropping a headline with a finger on the map or flicking the headline A on the map or outside the map.

  Therefore, the user can specify a place where information is re-presented by intuitively operating with a finger, and can concentrate on driving. In addition, information acquired inside the vehicle and detailed information viewed halfway can be automatically transferred in advance to a terminal device different from the vehicle-mounted device, so it is possible to view information obtained in the vehicle outside the vehicle. It becomes. Therefore, the degree of freedom of information acquisition location for the user increases.

  FIG. 5 is a screen image diagram showing a modification of the first embodiment, where (a) shows a state before the operation, and (b) shows a state after the operation. In this in-vehicle information display device, a plurality of information headings A are displayed in the left area (application display G1) of the display screen of the touch panel 3 as in FIG. 3, and the right map display area (map display G2). Displays the transfer destination folder F to be automatically transferred during operation. Here, three folders F, home, office, and smartphone are displayed.

  Then, the user drags and drops or flicks the selected heading A into any of the folders F. By doing so, the information linked to the heading A transferred to the folder F is automatically transferred to the address associated with the folder F. Therefore, the user can view the information transferred later on each terminal. In this case, especially by performing a drag-and-drop operation, it is possible to more reliably specify the transfer destination location of the selected heading A directly in the folder F, and the input operation can be easily performed.

<Second Embodiment>
FIG. 6 is a screen image diagram of the in-vehicle information display device according to the second embodiment of the present invention, where (a) shows a state before operation, and (b) shows a state after operation. As in FIG. 3, the heading A of each information is displayed in the left area (application display G1) on the display screen, and the map screen is displayed in the right area (map display G2).

  The user performs a predetermined specific input operation such as a check operation CK1 or a surrounding operation CK2 through the touch panel with respect to the headline A of interest from the headline A of the information presented on the left screen. By managing the input method and the re-presentation destination address with a link so that the specific input method and the information re-presentation location correspond in advance, the user can easily input the re-presentation destination of the information. Can improve convenience.

  Note that the input method is not limited to the one specified at the beginning, but may be updated using the communication means 5. The updated input method information can be managed by the user input information determination unit 11 and the update result can be displayed on the display / input unit 3.

  For example, in the above example, the check operation CK1 and the surrounding operation CK2 are adopted as the input method registered in advance, but a long press operation or a double press operation on the heading A of the selected information may be adopted. The displayed information may be re-presented when these operations are performed.

  As described above, according to the in-vehicle information display device of the present embodiment, for the heading A displayed on the touch panel (display / input unit 3), the details of the information linked by the user to the heading A are displayed. It is possible to select and operate whether the user wants to see the current time point or the later time point. If you want to see it now (normal tap operation), the details of the information will be displayed. On the other hand, if you want to see at a later point in time (check operation, surrounding operation, long press operation, double press operation, etc.), you can temporarily hold the displayed information, You can transfer information to and see details of the information at that location.

  Therefore, it is possible to view details of the information selected and operated at a place where the load on the passenger as a user is low or at a time when the load is low. As described above, even when the information heading A is displayed on the touch panel 3, the user can freely select and view the time and place the user wants to see for details of the information. For this reason, the user does not pay attention to the displayed information, and even if the displayed information cannot be fully seen on the spot for the user while driving the vehicle, the information is missed. The convenience as a vehicle-mounted information display apparatus can be improved by suppressing this.

<Third Embodiment>
A vehicle-mounted information display device 1B according to the third embodiment of the present invention will be described with reference to FIG. Since the basic configuration is the same as that of the in-vehicle information display device 1 according to the first embodiment shown in FIG. 1, only different points will be described below.

  When providing information in the vehicle, it is necessary to limit the amount of information provided and the timing of providing information by driving load so as not to increase the load on the user. The output control parameter measurement unit 25 in FIG. 7 uses information of an in-vehicle device (a user state estimation unit 26 such as a camera that captures the inside of the vehicle or a vehicle state estimation unit 28 such as a camera that captures the outside of the vehicle), Calculate time limit (margin time) and operation load (operation load) when providing information. Then, the user input information determination unit 11 compares the calculation result with the threshold value, and determines whether or not to re-present information.

  For example, the driving load on the user is calculated from the change in the face image of the user using information on a camera installed in the vehicle. If the calculated driving load is less than or equal to the threshold value, information is displayed on the display / input means 3 and the presentation is performed again, assuming that the driving load is small. If the threshold is exceeded, the information is not re-presented because the driving load is large. As a result, the user can view the information only when the driving load is small, and when the driving load is large, the information is displayed again for the user who is driving the vehicle on the spot. Even when the information cannot be sufficiently viewed, it is possible to suppress oversight of the information and to enhance the convenience as an in-vehicle information display device.

  In addition, even when it is determined that the driving load is large, when the user wants to re-present information proactively, such as when the user does not feel the driving load is large, By performing the operation, information can be presented again. At this time, information can be easily re-presented by performing an input operation using, for example, the display / input unit 3B including a voice input unit or a steering switch as a simple input unit that is easy for the user to input.

  The in-vehicle information display device 1B includes a normal operation recording unit 27 that records an average input operation of the user at the normal time. Even when the user tries to perform an input operation such as when the driving load is large, there is a possibility that the input operation changes in part different from the normal time due to the driving load. In this case, the user input information determination unit 11 determines that the input operation is a re-presentation operation by comparing with the normal operation recorded in the normal operation recording unit 27.

  As a result, even if the user cannot perform an input operation due to the driving load, the information can be treated as re-presentation, and the displayed information can be sufficiently seen on the spot for the user who is driving the vehicle. Even in such a case, it is possible to suppress the oversight of the information and to improve the convenience as an in-vehicle information display device.

  Further, the user determines a threshold value from the vehicle state estimated by the vehicle state estimation means 28 such as a camera that captures the outside of the vehicle (the vehicle state estimated based on the information obtained by detecting the white line on the travel path and the distance from the preceding vehicle). Information is re-presented when it is determined that there is an allowance for the predetermined time. In other words, by analyzing information collected by a camera that captures the outside of the vehicle and judging the current vehicle state from the vehicle information around the vehicle position, the stop time when the signal is stopped or when there is a traffic jam is estimated. When the set stop time is longer than a certain time and there is a margin, information is displayed on the display / input means 3 and presented again.

  Thus, the user can view the information only when the vehicle has a certain margin and the driving load is small for the user. On the other hand, when the vehicle has no margin and the driving load is large for the user, it is treated as re-presentation, so that the user who is driving the vehicle cannot fully see the displayed information on the spot. However, it is possible to improve the convenience as an in-vehicle information display device by preventing the information from being overlooked.

<Fourth Embodiment>
An in-vehicle information display device 1C according to a fourth embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 8, the basic configuration of the present embodiment is the same as that of the in-vehicle information display device 1 of the first embodiment shown in FIG. 1, and therefore only the differences will be described below.

  This in-vehicle information display device 1C has content identification means 29 as information type identification means. The content identification unit 29 identifies the type of information selected by the user when an input operation is performed by the user.

  For example, when the information selected by the user is “application icon B for distributing news” (FIG. 9), the content identifying unit 1C identifies that the target information is an icon, and re-presents the information. A control command is issued so that the information arranged according to the type (content) is re-presented in FIG. Specifically, if the target information is a news application, for example, only five topics of the day may be filtered and re-presented, or it may be estimated from the usage history or the like that the user likes golf. If possible, the information after filtering the information about the golf information based on the tag information attached to the news information can be presented again.

  According to the in-vehicle information display device 1C of this embodiment, the type of information to be re-presented can be determined and displayed by changing the amount of information according to the type. For example, when the information requested by the user to be re-presented is an icon of a news application, information is automatically extracted by extracting only new news or extracting only information that is highly user-friendly. Can be organized and re-presented.
