Description

  The present invention relates to an information device capable of performing various searches and settings based on a hierarchical selection screen configuration.

  For example, in a car navigation device, a map display around the current traveling position of the host vehicle, various input setting screens, and the like are displayed on a display device including a liquid crystal display provided in a vehicle interior (center part of the instrument panel). It is like that. Further, a touch panel (touch screen) is provided on the screen of the display device, and various selections can be made by directly touching various items (keys) called icons set on the screen by the user. And setting and input instructions.

  In this case, for example, when the user performs destination setting, the destination is searched and set while displaying a hierarchical selection screen on the display device, and the display screen (selection screen) at that time is displayed. Is a hierarchical structure (tree structure). Specifically, when the user wants to set, for example, a golf course in Aichi Prefecture as a destination, first, a menu screen (first layer) is displayed by operating a menu key. In this menu screen, a plurality of selection items such as “Destination search”, “Memory location”, and “Various settings” are displayed as icons. When the user selects “Destination search” (touch operation), A second-tier destination search screen having icons (selection items) such as “main facility”, “50 sounds”, and “phone number” is displayed.

  Next, when the user performs a selection operation (touch operation) on “main facility”, a display screen for selecting a facility type in the third hierarchy is displayed on the display device, and the user performs a selection operation on “golf course” on this screen. . Then, a selection screen for prefectures in the fourth hierarchy is displayed. When the user selects “Aichi Prefecture”, the screen is switched to a selection screen for golf course names in the fifth hierarchy. The user selects (inputs) the name of the golf course that he / she wants to go to on this screen, and finally operates the “destination setting” icon to complete the setting as the destination. Each screen is set with a “return” icon, and when this “return” is selected, the screen returns to the previous screen.

As described above, the hierarchical selection screen configuration allows the user to reach a target item (destination) from an enormous amount of items (destination). However, for example, even when a user frequently uses a search for a golf course in Aichi Prefecture, the user has to perform key operations (icon selection operations) many times before reaching the search. And may feel difficult to use. Therefore, conventionally, there has been considered one that can register a selection item (icon) desired by a user as a shortcut item (shortcut icon) (see, for example, Patent Document 1). According to this, by registering frequently used icons as shortcut icons, the user can improve the operability of subsequent destination search.
JP 2002-199081 A

  However, as in the above-mentioned Patent Document 1, in which a shortcut icon desired by the user is registered, the user is forced to perform an operation for registration. Therefore, the registration operation may be troublesome for the user. There was room for improvement in terms of user burden.

  The present invention has been made in view of the above circumstances, and its purpose is to perform various searches and settings based on a hierarchical selection screen configuration, and can automatically set shortcut items. It is to provide an information device that can reduce the burden on the user.

  For items that perform various searches and settings based on a hierarchical selection screen configuration, frequently used items are identified with repeated use, and the user performs the same operation over and over again. As the user gets used to the operation, the user learns the screen configuration, easily learns the location of the item to be operated next, and the time required for the operation (reaction time) becomes shorter. The present inventor has accomplished the present invention by paying attention to the fact that the reaction time is shortened when the user repeats the same operation over and over and becomes proficient in the operation.

That is, a first information device according to the present invention includes a display device that displays a selection screen including a plurality of items, an operation unit for selecting and operating items displayed on the screen of the display device, and hierarchically. Display data storage means for storing display data of the configured selection screen, and display on the screen of the display device while changing the selection screen hierarchically from the initial screen as the first hierarchy according to the operation of the operation means Display control means, timing means for measuring the reaction time from display of each selection screen of the display device to selection of an item by the operation means in each hierarchy, and selection of the nth hierarchy from the initial screen A determination means for determining whether or not the reaction time measured by the time measuring means until reaching the screen is a time proficient in the operation, and this determination means is determined to be a time proficient in the operation. A shortcut item setting means for automatically setting a shortcut item for transitioning to the selection screen of the n-th layer by omitting an intermediate screen transition on the initial screen or on a shortcut screen transitioned from the initial screen. And the determination means stores the initial reaction time measured by the timing means at the beginning of use, and is operated when the reaction time is shortened from the initial reaction time to a predetermined reduction rate or less. The present invention is characterized in that it is determined that it is a skilled time (invention of claim 1).

  In the present invention, the reaction time from the display of each selection screen on the display device to the selection operation of the item by the operation means is measured for each hierarchy by the time measuring means, and the nth hierarchy from the initial screen is determined by the judging means. It is determined whether or not the reaction time to reach the selection screen is a time that is skilled in operation. When it is determined by the determining means that the time is skillful in operation, the shortcut item setting means automatically sets the shortcut item. This makes it possible to automatically set frequently used items as shortcut items.

At this time, when the judgment means judges the skill, the initial reaction time measured by the timing means at the beginning of use is stored, and the reaction time is shortened from the initial reaction time to a predetermined reduction rate or less. In addition, since it is determined that the time is skillful in operation, it is possible to make a determination according to the difference in reaction time depending on the age of the user and the like, which is more effective.

A second information device according to the present invention is hierarchically configured with a display device that displays a selection screen including a plurality of items, and an operation means for selecting and operating items displayed on the screen of the display device. A display data storage means for storing display data of the selected screen, and a display for displaying the selection screen in a hierarchical transition from the initial screen as the first hierarchy on the display device screen in accordance with the operation of the operation means. Control means, timing means for measuring the reaction time from the display of each selection screen of the display device to the selection operation of the item by the operation means in each hierarchy, and from the initial screen to the selection screen of the nth hierarchy Until it is determined that the reaction time measured by the time measuring means is a time proficient in the operation, and when it is determined by the determining means that the time is proficient in the operation Shortcut item setting means for automatically setting a shortcut item for transitioning to the selection screen of the n-th layer by omitting intermediate screen transition on the initial screen or on a shortcut screen transitioned from the initial screen. The determination means compares the reaction time with a threshold value set in accordance with a user's age inputted in advance, and determines that the time is skillful in operation when it is equal to or less than the threshold value. (Invention of claim 2) This makes it possible to automatically set frequently used items as shortcut items. In addition, it is possible to make a determination according to the difference in reaction time depending on the user's age and the like, which is more effective.

By the way, even if the shortcut item is automatically set as described above, if the shortcut item is rarely used after that, leaving the shortcut item indefinitely is a waste of display space. May cause problems. Therefore, an automatic deletion unit may be provided that automatically deletes a shortcut item when the shortcut item is not selected for a predetermined period of time (invention of claim 3). According to this, unnecessary shortcut items can be automatically deleted without depending on the user's operation.

A third information device according to the present invention is hierarchically configured with a display device that displays a selection screen including a plurality of items, and an operating means for selecting and operating items displayed on the screen of the display device. A display data storage means for storing display data of the selected screen, and a display for displaying the selection screen in a hierarchical transition from the initial screen as the first hierarchy on the display device screen in accordance with the operation of the operation means. Control means, timing means for measuring the reaction time from the display of each selection screen of the display device to the selection operation of the item by the operation means in each hierarchy, and from the initial screen to the selection screen of the nth hierarchy Until it is determined that the reaction time measured by the time measuring means is a time proficient in the operation, and when it is determined by the determining means that the time is proficient in the operation Shortcut item setting means for automatically setting a shortcut item that transitions to the selection screen of the nth layer by omitting intermediate screen transition on the initial screen or on a shortcut screen that is transitioned from the initial screen, and the shortcut item Is provided with an automatic deletion means for automatically deleting the shortcut item when the selection operation is not performed for a predetermined period of time (invention of claim 4). This makes it possible to automatically set frequently used items as shortcut items. In addition, unnecessary shortcut items can be automatically deleted regardless of user operations.

In the present invention, manual deletion means for deleting a shortcut item can be provided by a user operation (invention of claim 5). Thereby, it is possible to delete a shortcut item that the user determines to be unnecessary. Note that the operation for deletion by the user can be completed more easily than the operation for registering a specific item. Further, a “return” item for returning to the previous hierarchy is displayed on each selection screen, and a “return” item is also displayed on the selection screen of the nth layer displayed by selecting the shortcut item. As a result of the selection operation, it is possible to return to the selection screen of the (n−1) -th layer as usual (invention of claim 6 ). This makes it easy for the user to use the “return” item.

  Hereinafter, an embodiment in which the present invention is applied to a car navigation apparatus will be described with reference to the drawings. First, FIG. 1 schematically shows an electrical configuration of a car navigation device 1 as an information device according to the present embodiment.

  Here, the car navigation apparatus 1 includes a position detector 3, a map database 4, an external memory 5, such as a VICS system, in a control apparatus 2 mainly composed of a microcomputer including a CPU, ROM, RAM, I / O, and the like. Connects external information input / output device 6 that transmits and receives data to and from the infrastructure, operation switch 7 that consists of a mechanical switch, display device 8 that consists of a full-color liquid crystal display, voice output device 9 that provides voice guidance, etc. Configured.

  The position detector 3 is composed of a GPS receiver, a vehicle speed sensor, a distance sensor, a direction sensor, and the like as is well known, and based on signals from these sensors, the current position (absolute position) of the host vehicle and the progress Direction, speed, travel distance, etc. are detected with high accuracy. Further, a touch panel 10 as an operation means is provided on the surface of the display device 8. A user (driver) can perform various instructions, inputs, settings, selections, and the like by operating the operation switch 7 and the touch panel 10.

  On the screen of the display device 8, a map around the current location of the vehicle is normally displayed at various scales, and a current location mark indicating the current location and the traveling direction of the vehicle is displayed so as to overlap the display. It has become. When the route guidance to the destination is executed, the display device 8 displays a route guidance screen. The display device 8 also displays a selection screen for the user to input and set (select) various destinations, various messages, and the like.

  The map database 4 is composed of a map data recording medium storing various data such as road map data in Japan and destination data (facility data) associated therewith, and a drive device for reading out the data. As the data recording medium, a large-capacity storage medium such as a DVD, a CD-ROM, or a hard disk is used. The road map data includes data such as road shape, road width, road name, signal, railroad crossing, building, various facilities, place name, terrain, etc., and for reproducing the road map on the screen of the display device 8. Contains data.

  The destination data consists of information on transportation facilities such as stations and airports, leisure facilities, accommodation facilities, public facilities, various stores such as retail stores, department stores, restaurants, residences and apartments, place names, etc. This data includes data such as the telephone number, address, latitude and longitude, and data for displaying a landmark indicating the facility on the road map on the display device 8 screen. It consists of

  In this case, in order to realize a destination search function to be described later, destination data is obtained for each of a plurality of genres such as leisure facilities, convenience stores, gas stations, restaurants, banks (ATM corners), and regions such as prefectures. It is possible to classify such as. The map database 4 stores display data of a selection screen to be displayed on the display device 8 when the destination search or the like is executed. Therefore, the map database 4 functions as display data storage means. As will be described later, this selection screen includes a plurality of items (icons) that are touch-operated by the user, and is configured hierarchically.

  The control device 2 realizes a location function for knowing the current location (vehicle position) of the vehicle by its software configuration (execution of a program), and searches for a route to a designated destination and guides the route. The search / guide function is realized. For example, a destination search function for searching for a facility of a specified genre and notifying the user is realized.

  Among them, the location function displays the road map on the display device 8 based on the map data from the map database 4 as described above, and the current location mark indicating the current location and the traveling direction of the vehicle based on the detection of the position detector 3. Is displayed. In this case, as the vehicle travels, the display of the current location moves on the map, and the map is scrolled according to the position of the vehicle. At this time, map matching is performed in which the current location of the vehicle is placed on the road.

  In addition, the route search / guidance function automatically calculates a recommended travel route (route) from the starting point of the vehicle (current location) to the destination specified by the user, for example, using a well-known Dijkstra method, This is a guide to the route to the requested destination. In this route guidance, the route to be traveled with the current location of the vehicle (current location mark) is displayed in a conspicuous color on the screen of the display device 8 so as to overlap with the road map. Information is provided.

  The control device 2 displays a selection screen including a plurality of items (icons) on the display device 8 when the execution of the destination search is instructed by the operation of the operation switch 7 and the touch panel 10 by the user. The user can select and specify the category to be searched, and search (extract) the corresponding destination based on the specification (touch operation on the touch panel 10). At this time, the control device 2 is configured to display the selection screen in a hierarchical transition from the initial screen (the menu screen shown in FIG. 3) that is the first layer on the screen of the display device 8. It functions as a display control means.

  At this time, as will be described in detail later, the control device 2 sets the reaction time t from the display of each selection screen of the display device 8 to the selection operation of the item (icon) by the touch panel 10 in each hierarchy. It is determined whether or not the reaction time t of each hierarchy from the initial screen to the selection screen of the nth hierarchy is a time experienced in operation. Then, when it is determined that the time is skillful in operation, the screen transition on the shortcut screen (see FIGS. 4 and 5) that is transitioned from the initial screen is omitted, and the selection screen of the nth layer is displayed. The shortcut items (shortcut icons) to be transitioned are automatically set. Therefore, the control device 2 functions as a time measuring means, a judging means, and a shortcut item setting means.

  In this case, more specifically, when the control device 2 determines whether or not the reaction time t is an operation-skilled time, the reaction time t is compared with a threshold value Δt, and if the reaction time t is less than the threshold value Δt, It is now judged that it was time. Here, the reaction time at the beginning of use (for example, the average reaction time in the initial 10 to several tens of operations) is stored, and the initial reaction time is multiplied by a predetermined time reduction rate (for example, 50%). Is the threshold value Δt. As a specific example, when the initial reaction time is 2 seconds, the threshold value Δt is 1 second.

  In this embodiment, the shortcut screen is provided with a “delete” icon (see FIGS. 4 and 5), so that shortcut items that are no longer needed can be deleted by a user operation. It has become. Therefore, this “delete” icon functions as a manual deletion means. Furthermore, in this embodiment, each selection screen displays a “return” item (icon) for returning to the previous hierarchy, and the nth layer displayed when the shortcut item is selected and operated. The selection screen is also configured to return to the selection screen of the (n−1) -th layer when the “return” item is selected.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, as described in the prior art, for example, a user who frequently goes to a golf course searches and sets a golf course in Aichi Prefecture as a destination in the car navigation device 1 as a specific example. explain.

  Now, when the user operates the menu key of the operation switch 7, the menu screen (first layer) is displayed on the display device 8. FIG. 3 shows an example of the menu screen. In this menu screen, a plurality of selection items such as “Destination Search”, “Memory Point”, “Various Settings”, and “Shortcut” are displayed as icons. When the user performs a selection operation (touch operation) on the “shortcut” item (icon) here, the selection screen displayed on the display device 8 transitions to a shortcut screen in the second hierarchy.

  4 and 5 show examples of shortcut screens. On this shortcut screen, for example, a shortcut item (shortcut icon) such as “facility search: golf course Aichi” or “memory location registration: history” is displayed. These are items (icons) that are originally displayed on the selection screen on the third and subsequent layers, but are automatically set as shortcut items on the shortcut screen by the processing described later. For example, when “facility search: golf course Aichi Prefecture” is selected and operated on this shortcut screen, the screen of the display device 8 omits intermediate screen transition and selects a golf course name selection screen (not shown). ).

  On the other hand, when a normal destination search is performed, the user performs a selection operation (touch operation) for “destination search” on the menu screen (FIG. 3). Then, although not shown, the screen of the display device 8 is changed to a destination search screen in the second hierarchy having icons (selection items) such as “main facility”, “50 sounds”, “phone number” and the like. Next, when the user selects and operates “main facility”, the display screen 8 displays a facility type selection screen on the third hierarchy, and the user selects and operates “golf course” on this screen. Then, the selection screen for prefectures in the fourth hierarchy is displayed. When the user selects “Aichi Prefecture”, the screen of the display device 8 displays a list of golf course names in the fifth hierarchy. Transit to the displayed selection screen.

  On the golf course name selection screen, the user selects the golf course name that he / she wants to go (or inputs with 50 sounds), and finally operates the “destination setting” icon to complete the setting as the destination. In this way, the hierarchical selection screen configuration allows the user to reach a target item (destination) from a huge amount of items (destination). In this case, the user selects (1) menu key, (2) “destination search”, (3) “main facility”, (4) “golf course”, (5) “Aichi Prefecture”, (6) “golf” The destination can be searched and set by seven operations of “place name” and (7) “destination setting” (selection completed).

  Now, when the user frequently searches for golf courses in Aichi Prefecture as described above, the skill level increases, and the item “Aichi Prefecture” in (5) above on the selection screen for prefectures in the fourth hierarchy Each operation up to the (icon) selection operation can be performed in a short time (for example, about 0.5 seconds) in a reflective manner. In the present embodiment, the control device 2 measures the reaction time t from the display of the selection screen of the display device 8 to the operation of selecting an item (icon) by the touch panel 10 based on the shortcut screen. Shortcut items are automatically set on the top.

  The flowchart of FIG. 2 shows the procedure for automatic setting of shortcut items executed by the control device 2. Here, as described above, it is assumed that the threshold value Δt for determining whether or not the reaction time t is a time experienced in the operation is set to 1.0 seconds, for example. That is, when the screen “N” of the nth layer is displayed in step S1, a timer is started in step S2. Then, in the next step S3, it is determined whether or not there is a button pressing operation (touch operation on the touch panel 10) on the screen “N”.

  If there is a touch operation (icon selection operation) on the touch panel 10 by the user (Yes in step S3), the timer is stopped in step S4. Thereby, the count time T of the timer is set as the reaction time t. In the next step S5, it is determined whether or not the reaction time t is larger than a threshold value Δt (for example, 1.0 second). If the reaction time t is equal to or less than the threshold value Δt, that is, if the reaction time is short (No in step S5), the timer is initialized in step S6, and n is incremented in step S7. The process proceeds to the screen display of the next layer.

  On the other hand, if the reaction time t is longer than the threshold value Δt in step S5, that is, if the reaction time is longer (Yes), the shortcut item that reaches the current screen “N” in step S8. Is set on the shortcut screen, and then the process proceeds to step S6. Note that the screen “N” related to the shortcut item automatically set in step S8 is, for example, the third and subsequent layers.

  Thereby, for example, a user who frequently searches for golf courses in Aichi Prefecture can select (2) “Destination search”, (3) “Main facilities”, (4) “ The response times of the operations up to “Golf course”, (5) “Aichi” are all 1 second or less (for example, 0.5 seconds), and (6) “Golf course name” is 1 in the operation (response time). If it takes more than 2 seconds (for example, 2 seconds), as shown in FIG. 4, a shortcut item ("Facilities Search: Golf Course Aichi Prefecture") leading to a golf course name selection screen in Aichi Prefecture is displayed on the shortcut screen. It will be set automatically.

  Therefore, in the same search after the next time, the user selects the “shortcut” icon on the menu screen, and the “facility search: golf course Aichi” item (icon) on the next shortcut screen displayed. When is selected, the middle is omitted and the screen changes to a golf course name selection screen in Aichi Prefecture. Thereby, simplification of the user's operation (reduction of the number of operations) can be achieved.

  In addition, although not shown, even when a golf course name selection screen in Aichi Prefecture is reached by operating a shortcut item, if the user operates the “return” icon on the screen, the screen does not return to the shortcut screen, but the normal transition It returns to the selection screen of the previous hierarchy on the street, in this case the selection screen of the prefecture. Furthermore, if the user thinks that a shortcut item is unnecessary on the shortcut screen, the corresponding shortcut item can be deleted by operating the “delete” icon.

  In this embodiment, shortcut items are automatically set in addition to the facility search described above. For example, when a desired point is registered as a memory point from the search history (a destination searched in the past), the user can select (1) menu key, (2) “memory point”, (3) “register”, ( 4) 5 operations of “history” and (5) list selection are performed. Also in this case, the reaction time of the operation until (4) “History” is all 1 second or less (for example, 0.5 seconds), and the reaction time (for example, more than 1 second for the selection operation of the list in (5)) 2 seconds), as shown in FIG. 5, the shortcut item (shortcut icon) of “memory location registration: history” is automatically set on the shortcut screen.

  As described above, according to the present embodiment, various searches and settings are performed based on the hierarchical selection screen configuration, and if the user repeats the same operation over and over again, the reaction time is shortened. Focusing on the fact that the shortcut item is based on measuring the reaction time t from the display of each selection screen on the display device 8 until the item (icon) selection operation by the touch panel 10 is performed for each layer. Configured to be set automatically. Therefore, unlike the case where the user registers shortcut items, it is possible to automatically set frequently used items (icons) as shortcut items, and it is possible to reduce the burden on the user.

  In particular, in this embodiment, the threshold Δt for determining whether or not the reaction time t is skillful in operation is a value obtained by multiplying the initial reaction time by a predetermined time reduction rate (for example, 50%), and the initial reaction. When the time is shortened to a predetermined shortening rate or less, it is determined that the time is skillful in operation. Thereby, it becomes possible to perform more effective judgment according to the difference in the reaction time depending on the age of the user.

  Further, it is possible to easily delete a shortcut item that the user determines to be unnecessary, and to solve problems such as waste of display space. Further, in the selection screen of the nth layer displayed by selecting the shortcut item, the selection of the (n−1) th layer is performed as usual by selecting the “return” icon. Since the screen is configured to return to the screen, the “return” icon can be easily used by the user.

The present invention is not limited to the above-described embodiment, and can be expanded and changed as follows. That is, the threshold value Δt for determining whether the time response time t is skilled in the operation, but it may also be set according to the age of the user that is input in advance. In this case, for example, the threshold value Δt is 1 second if the user's age is in their 20s or 30s, 1.5 seconds if the user is in their 40s or 50s, and 2 seconds if the user is over 60s. For example, the threshold value Δt can be increased as the age increases. This also makes it possible to make a determination according to the difference in reaction time depending on age and the like, which is more effective .

  An automatic deletion unit may be provided that automatically deletes a shortcut item that is automatically set when the shortcut item is not selected for a predetermined period. According to this, unnecessary shortcut items can be automatically deleted without depending on the user's operation.

  In the above embodiment, the shortcut screen is provided in the next layer of the menu screen, and the shortcut item is automatically set here. However, the shortcut item (shortcut icon) may be provided directly on the initial screen (menu screen). good. In addition, the present invention is not limited to the above-described car navigation device, and can be applied to various searches and settings in various information devices such as personal computers and mobile phones. It can be implemented with appropriate modifications.
