Description

  The present invention relates to an operation menu display control device and an operation menu display control method, and in particular, the vehicle travels for at least some of the operation items included in a hierarchical operation menu having a tree structure. The present invention relates to control for displaying an operation menu on a display unit of an information processing apparatus having a function of restricting operation so that the operation cannot be performed inside.

  In general, the operation menu displayed on the display of the in-vehicle device is often restricted so that the operation menu cannot be operated while traveling for the purpose of ensuring safety. In particular, in a hierarchical operation menu having a tree structure (hereinafter referred to as a hierarchical menu), it is assumed that many operations are required to complete a target task or a predetermined time or more is required. In some cases, operational restrictions are imposed. On the other hand, when the number of operations required to complete the target task is small, or when it is assumed that the operation will be completed within a predetermined time, it is possible not to restrict the operation. .

  Even when the operation of the hierarchical menu is restricted, in addition to restricting the operation so that it cannot be operated at all from the first level, it is possible to start from a plurality of levels after operating the operation item several times (that is, screen transitions). (In the middle) Restrictions may be imposed so that operations cannot be performed. Furthermore, the operation items that are restricted so that the operation items displayed on the operation menu of the first layer cannot be operated at all from the first layer, and the operation items that are restricted so that they cannot be operated from the middle of the screen transition In some cases, there may be mixed operation items that cannot be restricted at all.

  FIG. 9 is a diagram illustrating an example of a hierarchical menu of the in-vehicle device. FIG. 9A shows an operation menu (top menu) 211 in the first hierarchy. The top menu 211 includes six operation items 111 to 116. Of these, the two operation items 111 and 112 are operation items that are restricted so that they cannot be operated at all from the first level during traveling. In addition, it is assumed that the three operation items 113 to 115 are operation items that are restricted so that they cannot be operated from the middle of the screen transition during traveling. Further, it is assumed that the remaining one operation item 116 is an operation item that is not restricted at all.

  In this case, when the vehicle starts running with the top menu 211 displayed as shown in FIG. 9A, the two operation items 111 and 112 are grayed out and cannot be operated as shown in FIG. 9B. It becomes. On the other hand, even when traveling is started, the other operation items 113 to 116 remain operable. In this case, for example, when the operation item 114 is operated, an operation menu 224 in the second hierarchy is displayed as shown in FIG. When one of the operation items (operation item 124 in the example of FIG. 9C) is operated in the operation menu 224, an operation menu 234 in the third hierarchy is displayed as shown in FIG. 9D.

  The operation menu 234 in the third hierarchy includes a large number of operation items 131, 132,..., And all the operation items cannot be displayed on one page. Therefore, in order for the user to search for a desired operation item, it is necessary to further move the screen by operating the scroll button, and an operation while traveling is not preferable. Therefore, at the stage of transition to the operation menu 234 in FIG. 9D, all the operation items are grayed out and cannot be operated. In other words, in this example, the operation is not limited even when the vehicle is running until the operation menu 224 of the second hierarchy shown in FIG. 9C is displayed, and the screen transition is possible. When the operation menu 234 is changed, the operation is restricted, and the subsequent operation cannot be performed.

  In addition, a technology is known in which an input device configured to limit input acceptance by an input unit during traveling of a vehicle is released under a predetermined condition even when the vehicle is traveling. (For example, refer to Patent Document 1). This patent document 1 describes that the restriction on the acceptance of input by the input means is canceled based on the remaining selection number of selection candidates.

  In the example of FIG. 9, the operation items that can be restricted during operation of the vehicle are displayed grayed out while the vehicle is traveling, but a technique for changing the display color has also been proposed ( For example, see Patent Document 2). In the vehicle display device described in Patent Document 2, the input keys that can be operated while the vehicle is traveling and the input keys that are prohibited to operate while traveling are all displayed in the same color when the vehicle is stopped, while the operation is performed while traveling. Only the prohibited input keys are displayed in different colors.

JP 2013-54408 A JP-A-7-191612

  As shown in FIG. 9A, while the vehicle is stopped, all the operation items 111 to 116 of the top menu 211 are operable without being grayed out. For this reason, it is not clear at a glance which operation items are subject to operation restrictions during traveling. Therefore, when any operation item is operated while the vehicle is stopped, if the operation item is an item that is restricted during operation (operation items 111 and 112 in the example of FIG. 9), the operation starts. Then, the subsequent operation cannot be performed, and there is a problem that stress is given to the user.

  Further, not only the top menu 211 but also an operation restriction may be applied from the middle of the screen transition as shown in FIG. 9D, so that the confusion of the user is further increased. That is, even after the vehicle starts traveling, the operation items 113 to 116 of the top menu 211 can be operated as shown in FIG. 9B. For example, when the operation item 114 is selected and the operation is advanced, FIG. The subsequent operation cannot be performed from the screen of 9 (d). In this case, it is highly likely that the user can operate the operation item 114 with the top menu 211 on the assumption that the operation can be performed to the end, and the operation cannot be performed on the way. It becomes.

  The present invention has been made in order to solve such a problem, and grasps in advance an operation item that is subject to operation restriction during traveling of the vehicle among a plurality of operation items included in the operation menu. The purpose is to be able to avoid the situation where the user cannot actually operate in the middle of the screen transition.

In order to solve the above-described problems, in the present invention, the vehicle travels in a lower layer along the designated hierarchy or tree structure from among a plurality of operation items included in the operation menu of the hierarchy currently designated in the hierarchy menu. The restriction items that are the operation items that are subject to operation restrictions are determined, and among the operation items that are not currently restricted in the specified operation menu, the determined restriction items are used as other operation items. Are displayed in an identifiable manner. In particular, in the present invention, when an operation menu of a certain hierarchy is specified, it is included in a direct restriction item which is a restriction item included in the operation menu of the certain hierarchy and in an operation menu of a certain hierarchy. Among the operation items that cannot be restricted during operation of the vehicle, the operation items that include the restriction items in the operation menu of the lower layer when the operation item is operated to move through the tree structure. A certain indirect restriction item is discriminated, the direct restriction item and the indirect restriction item are displayed in a manner distinguishable from other operation items, and the direct restriction item and the indirect restriction item are displayed in a manner distinguishable from each other. I have to.

  According to the present invention configured as described above, among the plurality of operation items included in the displayed operation menu, the operation item that is not actually restricted at present is the currently specified hierarchy or lower layer. In this case, the restriction items that are subject to the operation restriction while the vehicle is traveling and the other operation items that are not subject to the operation restriction are displayed in an identifiable manner. As a result, among the plurality of operation items included in the displayed operation menu, the user can grasp in advance the operation items that will be subject to operation restrictions at any level while the vehicle is running, It can be avoided that the actual operation becomes impossible in the middle of the operation.

(First embodiment)
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of an in-vehicle device to which the operation menu display control device 10 according to the first embodiment is applied. As shown in FIG. 1, the in-vehicle device of the present embodiment includes an operation menu display control device 10, an operation unit 20, and a display unit 30. The operation unit 20 is configured by, for example, a remote control or a touch panel attached to the display unit 30. The display unit 30 is configured by, for example, a liquid crystal display device.

  The in-vehicle device according to the present embodiment places an operation restriction on at least some of the operation items included in the hierarchical operation menu having a tree structure so that the operation cannot be performed while the vehicle is running. It has a function. When the operation is restricted, for example, the operation items to be restricted are grayed out so that the operation cannot be performed.

  As shown in FIG. 1, the operation menu display control device 10 according to the first embodiment includes, as its functional configuration, an operation reception unit 11, a transition execution unit 12, a display control unit 13, a stop determination unit 14, and a restriction item determination unit. 15 is provided. In addition, the operation menu display control device 10 includes a hierarchical menu storage unit 16.

  Each of the functional blocks 11 to 15 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 11 to 15 is actually configured by including a CPU, RAM, ROM, and the like of a computer, and stored in a recording medium such as a RAM, ROM, hard disk, or semiconductor memory. Is realized by operating.

  The hierarchical menu storage unit 16 stores information related to a hierarchical menu having a tree structure. Information related to the hierarchical menu includes the tree structure of the hierarchical menu (indicating which operation item of the operation menu of a certain hierarchy is to be changed to which operation menu of the lower layer), operation items included in each operation menu, and operation items thereof Includes information such as a flag (hereinafter referred to as a restriction item flag) indicating whether or not the item is a restriction item that is restricted so that it cannot be operated while the vehicle is running.

  FIG. 2 is a diagram schematically illustrating an example of hierarchical menu information stored in the hierarchical menu storage unit 16. In FIG. 2, one operation menu 211 shown at the top is the top menu of the first hierarchy (corresponding to FIG. 9A). This operation menu 211 includes six operation items (corresponding to the operation items 111 to 116 in FIG. 9A), and two of them (operation items 111 and 112) are in the first hierarchy. In the operation menu 211, a flag “1” indicating that the operation menu 211 is a restriction item to which operation restriction can be applied is set.

  The six operation menus 221 to 226 shown second from the top are the operation menus in the second hierarchy that transition when the six operation items 111 to 116 included in the operation menu 211 in the first hierarchy are operated. It is. These operation menus 221 to 226 also store a plurality of operation items and restriction item flags included therein. In the example of FIG. 2, the fourth operation menu 224 (corresponding to FIG. 9C) includes four operation items 121 to 124, and the restriction item flag values for all of the operation items 121 to 124 are included. Is not set to “1”.

  Further, the four operation menus 231 to 234 shown in the third from the top are the operation menus in the third hierarchy that transition when the four operation items 121 to 124 included in the operation menu 224 in the second hierarchy are operated. It is. These operation menus 231 to 234 also store a plurality of operation items and restriction item flags included therein. In the example of FIG. 2, the fourth operation menu 234 (corresponding to FIG. 9D) includes n operation items 131 to 13n, all of which are displayed in the third-level operation menu 234. A flag “1” indicating that the operation is restricted is set.

  The operation accepting unit 11 accepts an operation of the hierarchical menu using the operation unit 20 by the user. Specifically, the operation reception unit 11 receives an operation for selecting and determining one of a plurality of operation items included in the operation menu.

  When the operation accepting unit 11 accepts an operation of the hierarchical menu by the user, the transition executing unit 12 displays an operation menu according to the operated operation item based on the hierarchical menu information stored in the hierarchical menu storage unit 16. Perform transition processing.

  The display control unit 13 causes the display unit 30 to display the operation menu transitioned by the transition execution unit 12. Here, the display control unit 13 changes the display mode of the operation menu depending on whether the vehicle is running or stopped. While the vehicle is running, among the plurality of operation items included in the operation menu, a restriction item that is restricted so that it cannot actually be operated (the restriction item flag is set to “1” as shown in FIG. 2). The display of the operation item) is grayed out (see FIGS. 9B and 9D). In this case, the operation accepting unit 11 does not accept an operation for the restricted item that is grayed out, and the transition executing unit 12 does not perform a transition of the operation menu.

  On the other hand, since the operation is possible even if it is a restriction item while the vehicle is stopped, the display control unit 13 displays all the operation items including the restriction item in an operable state without being grayed out. However, the display control unit 13 does not display all the operation items included in the operation menu (corresponding to the operation items that are not currently restricted during operation) in the same manner. It is displayed in a manner distinguishable from other operation items. Details of this will be described later.

  The stop determination unit 14 determines whether or not the vehicle is stopped. For example, the stop determination unit 14 determines whether or not the vehicle is stopped based on whether or not the traveling speed information (speedometer information) transmitted via the in-vehicle LAN or the like indicates zero. Then, the determination result is notified to the transition execution unit 12 and the display control unit 13. As described above, the display control unit 13 changes the display mode of the operation menu according to the determination result of whether or not the vehicle is stopped by the stop determination unit 14. Moreover, the transition execution part 12 performs operation | movement of whether to perform the transition of an operation menu, when operation is performed with respect to a restriction | limiting item according to the determination result of whether the stop determination part 14 is stopping. Change.

  Based on the hierarchical menu information (particularly, the restricted item flag) stored in the hierarchical menu storage unit 16, the restricted item determination unit 15 selects a plurality of operation items included in the operation menu of the currently designated hierarchy. An operation item that is subject to operation restrictions in the designated hierarchy when the vehicle travels (because a direct restriction is applied to the displayed operation item, this is hereinafter referred to as a direct restriction item). Determine. In other words, when an operation menu of a certain hierarchy is designated, the restriction item determination unit 15 determines a direct restriction item that is a restriction item included in the operation menu of the certain hierarchy. Then, the determined direct restriction item is notified to the display control unit 13.

  As described above, when the stop determination unit 14 determines that the vehicle is stopped, the display control unit 13 can identify the direct restriction item determined by the restriction item determination unit 15 from other operation items. To display. For example, the shape or background color of the restriction item frame is directly changed so that it can be identified. Or, change the font size, font type (Gothic / Mincho, etc.), font design (Bold / Italic, etc.), font color, etc. of the character string displayed as the name of the direct restriction item so that it can be identified. Also good. As another example, a predetermined icon may be added to the direct restriction item and displayed.

  FIG. 3 is a diagram illustrating an example of an operation menu displayed on the display unit 30 by the display control unit 13 while the vehicle is stopped. 3A shows a display example of the operation menu 211 in the first hierarchy, and FIG. 3B shows a display example of the operation menu 234 in the third hierarchy.

  In the example illustrated in FIG. 3A, the display control unit 13 directly displays the restriction items 111 and 112 determined by the restriction item determination unit 15 in the operation menu 211 in the first hierarchy (as shown in FIG. 2). Among the operation items 111 to 116 included in the operation menu 211, those having the restriction item flag set to “1”) are displayed in a manner different from the other operation items 113 to 116.

  By displaying in this way, the user can grasp in advance the operation items 111 and 112 that cannot be operated when the vehicle starts running while the vehicle is stopped. Thereby, the user can exercise the consciousness to operate any of the other operation items 113 to 116 without operating the operation items 111 and 112 even when the operation is possible while the vehicle is stopped. For example, when the operation menu 211 is a destination setting menu and includes a plurality of operation items 111 to 116 such as address search, facility name search, facility genre search, telephone number search, history search, registration location search, etc. Assume that the address search and facility name search operation items 111 and 112 are directly restricted items. In this case, the user can know in advance that the operation cannot be performed while traveling if an address search or a facility name search is performed, and therefore, the user can be conscious of setting a destination by another search method.

  In the example shown in FIG. 3B, the display control unit 13 displays the direct restriction items 131 to 136 determined by the restriction item determination unit 15 in the operation menu 234 in the third hierarchy (as shown in FIG. 2). Among the operation items included in the operation menu 234 in the middle, the restriction item flag is set to “1”) is displayed in a manner different from the other operation items. In this example, since all the operation items 131 to 13n included in the operation menu 234 are direct restriction items, all are displayed in a form for direct restriction items.

  By displaying in this way, when the user operates the operation menus 211 and 224 in order while the vehicle is stopped to display the operation menu 234 in the third hierarchy, the operation menu 234 can not be operated at all during traveling. Can be grasped in advance. Thus, the user stops operating the operation item 114 that can be operated while traveling instead of the direct restriction items 111 and 112, and returns to the top menu 211 to return to another operation item 113, 115, The consciousness of operating any one of 116 can be exercised.

  FIG. 4 is a flowchart showing an operation example of the operation menu display control device 10 according to the first embodiment configured as described above. The flowchart shown in FIG. 4 starts when the operation receiving unit 11 receives an operation for displaying the operation menu 211 in the first hierarchy.

  When the operation receiving unit 11 receives an operation for displaying the operation menu 211 of the first hierarchy, the transition execution unit 12 is based on the information of the operation menu 211 of the first hierarchy stored in the hierarchy menu storage unit 16. Then, a process of transitioning to the operation menu 211 of the first hierarchy is performed (step S1).

  Next, the restriction item determination unit 15 performs a plurality of operations included in the operation menu 211 based on the information (particularly, the restriction item flag) of the operation menu 211 in the first hierarchy stored in the hierarchy menu storage unit 16. The restriction items 111 and 112 are directly discriminated from the items 111 to 116 (step S2).

  Subsequently, the stop determination unit 14 determines whether or not the vehicle is stopped (step S3). Here, when it is determined that the vehicle is stopped, the display control unit 13 makes the direct restriction items 111 and 112 determined by the restriction item determination unit 15 distinguishable from the other operation items 113 to 116. Then, the first-level operation menu 211 is displayed on the display unit 30 (step S4).

  On the other hand, when it is determined that the vehicle is running, the display control unit 13 grays out the direct restriction items 111 and 112 determined by the restriction item determination unit 15 so that the operation cannot be performed, and operates the first level. The menu 211 is displayed on the display unit 30 (step S5).

  After the display control unit 13 displays the first-level operation menu 211 in either step S4 or step S5, the operation reception unit 11 selects one of the operation items 111 to 116 included in the operation menu 211. It is determined whether an operation has been accepted (step S6). If any operation is accepted, the process returns to step S1. In step S <b> 1, the transition execution unit 12 performs a process of transitioning the operation menu according to the operated operation item.

  In step S6, when any operation of the operation items 111 to 116 is not received, the operation receiving unit 11 determines whether or not an operation for ending the operation menu operation is received (step S7). If the operation accepting unit 11 has not accepted the end operation, the process returns to step S6. On the other hand, when the operation accepting unit 11 accepts an end operation, the process of the flowchart shown in FIG. 4 ends.

  As described above in detail, in the first embodiment, from among a plurality of operation items included in the operation menu of the currently specified hierarchy, operation restriction is applied while the vehicle is traveling in the operation menu. When the vehicle is stopped, the determined direct restriction item is displayed in a manner that can be distinguished from other operation items.

  According to the first embodiment configured as described above, a plurality of operation items included in the displayed operation menu are directly restricted items that are subject to operation restriction during traveling of the vehicle, and operation restriction is applied. The other operation items that cannot be displayed are displayed in an identifiable manner. Thereby, it is possible to cause the user to grasp in advance the operation items that are to be subjected to the operation restriction while the vehicle is traveling among the plurality of operation items included in the displayed operation menu. As a result, even when the vehicle is stopped and in an operable state, the user can be prevented from operating the restriction items, so that the user cannot actually operate during the transition of the screen during traveling. It can be avoided.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a diagram illustrating a configuration example of an in-vehicle device to which the operation menu display control device 10 ′ according to the second embodiment is applied. In FIG. 5, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here. FIG. 6 is a diagram illustrating a display example of an operation menu according to the second embodiment.

  As shown in FIG. 5, the operation menu display control device 10 ′ according to the second embodiment is different from the display control unit 13 and the restriction item determination unit 15 shown in FIG. Part 15 '.

  The restriction item determination unit 15 ′ determines an indirect restriction item in addition to the direct restriction item described in the first embodiment when an operation menu in a certain hierarchy is designated. An indirect restriction item refers to an operation item that is subject to operation restriction in a lower layer traced from the designated hierarchy along the tree structure. Specifically, among the operation items that are included in the operation menu of the specified hierarchy and the operation restriction cannot be applied while the vehicle is running (operation items that are not direct restriction items), the operation item This is an operation item in which a restriction item is included in the operation menu in the lower layer when a transition is made by tracing the tree structure.

  Here, the direct restriction item and the indirect restriction item will be described in detail. In the example of FIG. 9A, the operation items 111 and 112 are direct restriction items, and the operation items 113 to 115 are indirect restriction items. That is, in the example of FIG. 2, when the first-level operation menu 211 is specified and displayed, the restriction item flag is set to “1” in the information related to the first-level operation menu 211 itself. The operation items 111 and 112 correspond to direct restriction items.

  On the other hand, for example, regarding the operation item 114 included in the operation menu 211 of the first hierarchy, the restriction item flag is not set to “1” in the information related to the operation menu 211 of the first hierarchy. However, the information related to the operation menu 234 in the third hierarchy that is shifted along the tree structure when the operation item 114 is operated includes an operation item in which the restriction item flag is set to “1”. In such a case, the operation item 114 corresponds to an indirect restriction item. In this case, the operation item 124 included in the operation menu 224 of the second hierarchy in the middle of the transition also corresponds to the indirect restriction item.

  Note that here, the operation item 114 in the first layer and the operation item 124 in the second layer are both operation items on the route to the operation menu 234 of the third layer, which is subject to operation restrictions during traveling. Although it corresponds to a restriction item, it is not limited to this. For example, only the operation item 124 that is shifted to the operation menu 234 in the third hierarchy in which the operation restriction is applied to all the operation items 131 to 13n may correspond to the indirect restriction item.

  That is, if the operation item 124 is operated in the operation menu 224 in the second hierarchy that is changed by the operation of the operation item 114, the operation menu 234 in the third hierarchy cannot be operated at all. On the other hand, if any one of the other operation items 121 to 123 is operated, it is assumed that a path that can be traced to the operation menu at the lowest layer by following the tree structure is included. In such a case, the operation item 114 to be shifted to the operation menu 224 in the second hierarchy may not correspond to the indirect restriction item.

  The display control unit 13 ′ includes the direct restriction items and the indirect restriction items determined by the restriction item determination unit 15 ′ among the operation items that are included in the operation menu and are not currently restricted. Are displayed in a manner that can be distinguished from the operation items. For example, in the case of the operation menu 211 in the first hierarchy, all the operation items 111 to 116 correspond to the operation items that are not subjected to operation restriction at this time (FIG. 9A). reference).

  In this case, the display control unit 13 ′, as shown in FIG. 6A, directly restricts items determined by the limit item determining unit 15 ′ among the operation items 111 to 116 for which no operation limitation is currently applied. 111 and 112 and the indirect restriction items 113 to 115 are displayed in a manner distinguishable from other operation items 116.

  Further, when the vehicle is running, the other operation items 113 to 116 except for the direct restriction items 11 and 112 displayed in a grayed out manner correspond to the operation items for which no operation restriction is currently applied (see FIG. 9 (b)). In this case, as shown in FIG. 6B, the display control unit 13 ′ displays the indirect restriction items determined by the restriction item determination unit 15 ′ among the operation items 113 to 116 for which no operation restriction is currently applied. 113 to 115 are displayed in a manner distinguishable from the other operation items 116.

  FIG. 7 is a flowchart showing an operation example of the operation menu display control device 10 ′ according to the second embodiment configured as described above. Note that the flowchart shown in FIG. 7 starts when the operation receiving unit 11 receives an operation for displaying the first-level operation menu 211.

  When the operation receiving unit 11 receives an operation for displaying the operation menu 211 of the first hierarchy, the transition execution unit 12 is based on the information of the operation menu 211 of the first hierarchy stored in the hierarchy menu storage unit 16. Then, a process of transitioning to the operation menu 211 of the first hierarchy is performed (step S11).

  Next, based on the information (especially the restriction item flag) of the operation menu 211 of the first hierarchy stored in the hierarchy menu storage unit 16, the restriction item determination unit 15 ′ includes a plurality of items included in the operation menu 211. The restriction items 111 and 112 are directly discriminated from the operation items 111 to 116 (step S12).

  In addition, the restriction item determination unit 15 ′ uses a plurality of operation menu information (particularly restriction item flags) stored in the hierarchy menu storage unit 16 to include a plurality of operation menus 211 included in the first hierarchy operation menu 211. Indirect restriction items 113 to 115 are determined from the operation items 111 to 116 (step S13).

  Subsequently, the stop determination unit 14 determines whether or not the vehicle is stopped (step S14). Here, when it is determined that the vehicle is stopped, the display control unit 13 ′ displays the direct restriction items 111 and 112 and the indirect restriction items 113 to 115 determined by the restriction item determination unit 15 ′ as other operation items. The operation menu 211 in the first hierarchy is displayed on the display unit 30 in a form that can be identified as 116 (step S15).

  On the other hand, when it is determined that the vehicle is running, the display control unit 13 ′ grays out the direct restriction items 111 and 112 determined by the restriction item determination unit 15 ′ so that they cannot be operated. The indirect restriction items 113 to 115 discriminated by the discriminating unit 15 ′ are made distinguishable from the other operation items 116, and the first hierarchy operation menu 211 is displayed on the display unit 30 (step S 16).

  After the display control unit 13 ′ displays the first-level operation menu 211 in either step S15 or step S16, the operation reception unit 11 selects one of the operation items 111 to 116 included in the operation menu 211. It is determined whether or not the operation has been accepted (step S17). If any operation is accepted, the process returns to step S11. In step S <b> 11, the transition executing unit 12 performs a process of transitioning the operation menu according to the operated operation item.

  If any operation of the operation items 111 to 116 is not received in step S17, the operation receiving unit 11 determines whether an operation for ending the operation menu operation is received (step S18). If the operation accepting unit 11 has not accepted the end operation, the process returns to step S17. On the other hand, when the operation accepting unit 11 accepts an end operation, the process of the flowchart shown in FIG. 7 ends.

  As described above in detail, in the second embodiment, an indirect restriction item is determined in addition to a direct restriction item from among a plurality of operation items included in the operation menu of the currently specified hierarchy, and the operation restriction is currently performed. Among the operation items that are not applied, the determined direct restriction item and indirect restriction item are displayed in a manner that can be distinguished from other operation items.

  In the first embodiment described above, for the indirect restriction item 114, the user operates the first hierarchy operation menu 211 and the second hierarchy operation menu 224 in order while the vehicle is stopped to sequentially operate the third hierarchy operation menu. If 234 is not displayed, it cannot be confirmed that the operation menu 234 cannot be operated while traveling. On the other hand, according to the second embodiment, the operation item 114 can be obtained only by looking at the operation menu 211 of the first layer without operating the actual operation item and following the operation menu 234 of the third layer. It is possible to grasp in advance that the operation restriction will be applied while the vehicle is traveling in the lower layer by operating. Thereby, the convenience of the user is further improved as compared with the first embodiment.

  Further, as shown in FIG. 8, the display control unit 13 ′ displays the direct restriction items 111 and 112 and the indirect restriction items 113 to 115 in a manner that can be distinguished from each other in the operation menu 211 that is displayed while the vehicle is stopped. You may make it make it. In this way, just by looking at the operation menu of the currently specified hierarchy, the operation item is directly restricted in that hierarchy, or indirectly restricted in the lower hierarchy than the designated hierarchy. You can see at a glance whether it is an operation item.

  In the first and second embodiments, the in-vehicle device is described as an example of the information processing apparatus having a function of restricting the operation items so that the operation cannot be performed while the vehicle is running. However, the present invention is not limited to this. . For example, the operation menu display control devices 10 and 10 ′ according to the first embodiment or the second embodiment can be applied to a smartphone or a portable navigation device that can be used by being brought into a vehicle.

  Moreover, although the said 1st and 2nd embodiment demonstrated the example which displays grayed out and displayed the operation item to which operation restriction was applied during driving | running | working of a vehicle, it is not limited to this. For example, you may make it hide the operation item to which the operation restriction was applied during driving | running | working of a vehicle.

  In the second embodiment, the direct restriction item and the indirect restriction item are referred to in such a manner that they can be distinguished from each other. However, a plurality of indirect restriction items are included in the currently designated operation menu. In such a case, the indirectly restricted items may be displayed in a manner that allows them to be distinguished from each other. For example, the display mode of the indirectly restricted items may be changed depending on how many levels below the currently designated hierarchy are subject to operation restrictions.

  In addition, each of the first and second embodiments described above is merely an example of a specific example for carrying out the present invention, and the technical scope of the present invention should not be interpreted in a limited manner. It will not be. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
