Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the display as in Patent Document 1 is effective when the screen of the navigation device is large, but it is not suitable for route guidance using a device with a small screen. For example, when performing route guidance using a mobile phone with a screen size of about 4 inches, compared with a normal navigation device with a screen size of about 7 inches, the screen is small, so if a lot of information is displayed on the same screen, each image and character will become small, making it difficult for the user to view.

[0005] The present invention has been made to solve the above problems, and the main object is to provide a route display device capable of clearly displaying information on a plurality of guidance points even when using a device with a small display screen.

[0008] The invention described in claim 10 is a route display method performed by a portable terminal having a display unit, comprising a display step of displaying on the display unit a guidance image showing guidance information for a route from a departure point to a destination and a route image corresponding to the guidance, wherein the display step is characterized by displaying a button to switch between the guidance image showing the guidance information and the route image corresponding to the guidance, a guidance image showing guidance information different from the guidance, and a route image corresponding to the guidance image but different from the route image.

[0009] The invention described in claim 11 is a route display program executed by a portable terminal having a display unit and a computer, characterized in that the computer is instructed to perform the steps of: displaying on the display unit a guidance image showing guidance information for a route from a departure point to a destination and a route image corresponding to the guidance; and displaying a button to switch between the guidance image showing guidance information and the route image corresponding to the guidance to a guidance image showing guidance information different from the guidance, and a route image corresponding to the guidance image, which is different from the route image.

[0010] The invention described in claim 12 is a route display program executed by a portable terminal having a display unit and a computer, wherein the computer functions as a display means for displaying on the display unit a guidance image showing guidance information for a route from a departure point to a destination and a route image corresponding to the guidance, and the display means is characterized in that, by a left or right flick operation on the guidance image, the guidance image showing guidance information and the route image corresponding to the guidance are switched to a guidance image showing guidance information different from the guidance and a route image corresponding to the guidance image, and a route image different from the route image corresponding to the guidance image. [Brief explanation of the drawing]

[0011] [Figure 1] This shows a front view of the mobile device. [Figure 2] This shows the general configuration of a mobile device. [Figure 3] An example of the display is shown using the examples provided. [Figure 4] An example of the display is shown using the examples provided. [Figure 5] This is a flowchart of the route display process according to the example. [Figure 6] An example of the system configuration related to the modified version is shown. [Modes for carrying out the invention]

[0012] In a preferred embodiment of the present invention, the route display device includes a route information acquisition means for acquiring route information indicating a route from a departure point to a destination, and a display means for displaying a guide point image including information on guide points along the route on a display unit, wherein when a predetermined touch operation is performed on the guide point image, the display means displays a guide point list, which is a list of the guide points, on the display unit.

[0013] The above-described route display device is, for example, a mobile device such as a smartphone, and acquires route information to a destination specified by the user. The route information includes guidance points to the destination, and the display means displays guidance point images containing information about the guidance points on the display unit. When the user touches a guidance point image, the display means displays a guidance point list, which is a list of guidance points. This allows the user to view a list of multiple guidance points as needed, even when using a device with a relatively small display screen, such as a mobile device. Furthermore, the user can close the display of the guidance point list when it is not needed and display only the necessary information, such as information about the next guidance point, thus effectively utilizing the limited size of the display screen. Preferably, the display means terminates the display of the guidance point images when displaying the guidance point list.

[0014] In one embodiment of the above-described route display device, the display means terminates the display of the guide point list when a flick operation is performed on the guide point list. This allows the guide point list to be closed with a simple operation.

[0015] In another embodiment of the route display device described above, the display means displays a scroll button if the number of guide points included in the route information is greater than the number of guide points that can be displayed on one screen of the guide point list, and changes the guide points to be displayed in response to the operation of the scroll button or a flick operation on the displayed guide point list. This allows the user to see information on all guide points even if there are many guide points.

[0016] In another aspect of the above route display device, the display means displays, separately from the scroll button, a list operation button for instructing the end of the display of the guidance point list. Thereby, it is possible to distinguish between the scroll operation of the guidance point list and the operation of closing the guidance point list.

[0017] In another aspect of the above route display device, when a flick operation is performed on the guidance point list, if a predetermined attention guidance point is included in the guidance point, the display means stops the scroll of the guidance point list for the flick operation with the attention guidance point displayed, and displays the attention guidance point in a manner different from other guidance points. Thereby, the user can be notified of the attention guidance point. In a preferred example, the attention guidance point is a guidance point corresponding to an entrance / exit of an expressway, a guidance point where traffic congestion has occurred, etc.

[0018] In another aspect of the above route display device, when a flick operation is performed on the guidance point image, the display means displays information on the guidance points before and after the currently displayed guidance point. Thereby, the guidance point to be displayed can be changed by a simple operation.

[0019] [[ID=P]] In another aspect of the above route display device, when any guidance point in the guidance point list is selected, the display means ends the display of the guidance point list and displays the guidance point image of the selected guidance point. Thereby, the user can easily select and display the information of the guidance point of interest.

[0020] Another preferred embodiment of the present invention is a route display method executed by a route display device having a display unit, the method including a route information acquisition step of acquiring route information indicating a route from a departure point to a destination, and a display step of displaying a guidance point image including information on guidance points on the route on the display unit. The display step displays a guidance point list, which is a list of the guidance points, on the display unit when a predetermined touch operation is performed on the guidance point image. Also by this method, information on a plurality of guidance points can be easily displayed using a device having a small display screen.

[0021] Another preferred embodiment of the present invention is a route display program executed by a route display device having a display unit and a computer, the program causing the computer to function as a route information acquisition means for acquiring route information indicating a route from a departure point to a destination, and a display means for displaying a guidance point image including information on guidance points on the route on the display unit. The display means displays a guidance point list, which is a list of the guidance points, on the display unit when a predetermined touch operation is performed on the guidance point image. By executing this program on a mobile terminal or the like, the above-described route display device can be realized. This program can be stored and handled in a storage medium.

Example

[0022] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0023] [1] Overall configuration [[ID=??]] FIG. 1 shows a front view of a mobile terminal 100 to which a route display device according to the present invention is applied. The mobile terminal 100 is portable by a user and has a display 110 on which a touch panel 120 is laminated. The mobile terminal 100 provides route guidance to a designated destination for a vehicle or the like.

[0024] Note: There seems to be an error in the tag in the original text. It should probably be for consistency with the other tags. The translation above assumes this correction.Figure 2 shows the schematic configuration of the mobile terminal 100. As shown in Figure 2, the mobile terminal 100 comprises an output unit 11, an input unit 12, a storage unit 13, a communication unit 14, a battery 15, a GPS receiver 16, and a control unit 17. Each element of the mobile terminal 100 is interconnected via a bus 10, and is configured to enable the transmission of necessary information between each element.

[0025] The output unit 11 includes a display 110 and a speaker 111 that outputs sound, and outputs information to respond to user operations on the mobile terminal 100 based on the control of the control unit 17. The input unit 12 includes a touch panel 120 and is an interface that accepts the input of necessary commands and information, i.e., operations, performed by the user of the mobile terminal 100. For example, the input unit 12 accepts input to specify a destination or input to specify conditions for route searching. In addition to the touch panel 120, the input unit 12 may also have keys, switches, buttons, voice input devices, etc., for inputting various commands and data.

[0026] The storage unit 13 stores programs for controlling the operation of the mobile terminal 100 and holds information necessary for the operation of the mobile terminal 100. For example, the storage unit 13 stores various data used for navigation processing, such as map data. The map data includes road data represented by links corresponding to roads and nodes corresponding to road connections (intersections), as well as facility information about each facility.

[0027] The communication unit 14 transmits and receives data with other devices according to a predetermined protocol. For example, based on the control of the control unit 17, the communication unit 14 receives screen information to be displayed on the display 110 from a server device via a network such as the Internet. The communication unit 14 also receives applications from the server in response to user operations and stores them in the storage unit 13. In this embodiment, route display processing can be achieved by executing a route display program downloaded from the server and stored in the storage unit 13.

[0028] The battery 15 is a rechargeable and dischargeable battery that stores the power necessary for the operation of the mobile terminal 100. The GPS receiver 16 receives radio waves from multiple GPS satellites that carry downlink data including positioning data, generates information about the current location of the mobile terminal 100, and transmits it to the control unit 17.

[0029] The control unit 17 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc. (not shown), and performs various controls on each component within the mobile terminal 100.

[0030] For example, the control unit 17 receives input specifying a destination from the input unit 12 and provides route guidance to the specified destination. The control unit 17 is an example of route information acquisition means and display means in the present invention.

[0031] In addition to the components shown in Figure 2, the mobile terminal 100 may also be equipped with various autonomous positioning devices such as an accelerometer, an angular velocity sensor, and a distance sensor. Alternatively, the mobile terminal 100 may be configured to communicate with an external device equipped with a GPS receiver, an accelerometer, an angular velocity sensor, and a distance sensor in order to obtain more accurate location information.

[0032] [2] Route display Next, an embodiment of the route display according to the present invention will be described. In the following embodiment, the mobile terminal 100 determines a route to a destination specified by the user and performs route guidance along that route. The mobile terminal 100 also displays information about one or more guidance points along the route to the destination in response to user operation.

[0033] Figure 3(a) shows an example of the display on the mobile terminal 100 during route guidance. The display example in Figure 3(a) shows the route centered on the current location of the mobile terminal 100, and will be referred to as "current location mode" below. In current location mode, the display 110 shows the guidance plate 20, the current location image 30, and the mode bar 40.

[0034] The guidance plate 20 is an area that displays information about the next guidance point on the route to the destination. Specifically, the guidance plate 20 includes a directional arrow 21 indicating the direction of travel at the next guidance point, the distance 22 from the current location to the next guidance point, and the name of the next guidance point (such as the name of an intersection) 23. In the example in Figure 3(a), the guidance plate 20 indicates to proceed diagonally to the right and forward at intersection A, 300m away. Note that the guidance plate 20 is an example of a guidance point image in this invention.

[0035] The current location image 30 displays the navigation route 31 to the destination and the current location marker 32 indicating the current location of the mobile device 100 on the map. The navigation route 31 is distinguished from other roads on the map by its color and thickness. The current location image 30 also includes scale change buttons 33 and 34, a scale bar 35, and an estimated time of arrival 36. The scale change button 33 is used to change the scale to display a more detailed map than the current one, and the scale change button 34 is used to change the scale to display a wider area map than the current one. The scale bar 35 indicates the current scale of the map shown in the current location image 30. The estimated time of arrival 36 indicates the estimated time of arrival at the destination if the navigation route is followed.

[0036] The mode bar 40 is an area that displays buttons corresponding to commands related to map display, etc. In this example, the menu button 40, current location button 42, and route button 43 are displayed. The menu button 40 is a button that displays the main menu of this navigation application. The current location button 42 is a button that instructs the system to display in current location mode. The route button 43 is a button that allows users to set a new route to their destination, change the current route, etc.

[0037] Now, in the display example shown in Figure 3(a), when the user touches the guidance plate 20, the display on the display 110 switches to the guidance point mode shown in Figure 3(b). The guidance point mode shows an outline of the guidance route, including the current location and a specific guidance point.

[0038] In the guidance point mode, the display 110 shows a guidance plate 20, a partial route image 30X, and a mode bar 40. In guidance point mode, the guidance plate 20 displays a direction arrow 21, the distance to the next guidance point 22, the name of the next guidance point 23, as well as a left button 24 and a right button 25. The left button 24 and the right button 25 are used to change the displayed guidance point to the previous or next guidance point on the guidance route. Specifically, when the user touches the left button 24, the guidance point (intersection A) immediately preceding the currently displayed guidance point (intersection B) is displayed. Similarly, when the user touches the right button 25, the guidance point (intersection C) immediately following the currently displayed guidance point (intersection B) is displayed. Note that if there is no previous guidance point on the guidance route, the left button 24 is not displayed, and if there is no next guidance point, the right button 25 is not displayed. Additionally, instead of touching the left button 24, flicking the guide plate 20 to the right will display the previous guide location, and instead of touching the right button 25, flicking the guide plate 20 to the left will display the next guide location. Note that "flicking" refers to the operation of slightly sliding or quickly swiping a finger on the touch panel screen.

[0039] In addition, in the guidance point mode, a list button 27a is displayed adjacent to the guidance plate 20. The list button 27a is used to display the guidance point list, which is a list of guidance points, but its details will be described later.

[0040] The partial route image 30X, like the current location image 30, displays the guidance route 31 and the current location marker 32 on the map. However, by simultaneously displaying a specific guidance point designated by the user and the current location marker 32, it shows the portion of the route from the current location to that guidance point. Specifically, as shown in Figure 3(b), in the partial route image 30X, the map, guidance route 31, and current location marker 32 are displayed so that the guidance point being displayed is in the center, i.e., at the position of the cross mark 37. In addition, the partial route image 30X displays the distance 38 from the current location to the guidance point being displayed (intersection B).

[0041] In addition, the partial route image 30X also displays the scale change buttons 33 and 34 and the scale bar 35, just as in the current location image 30. Furthermore, the content displayed on the mode bar 40 in the partial route image 30X is the same as in the current location image 30.

[0042] Figure 3(c) shows an example of displaying the next guidance point in guidance point mode. That is, in the display example of Figure 3(b), if the user touches the right button 25 or flicks the guidance plate 20 to the left, the example of Figure 3(c) is displayed. Touching the right button 25 or flicking to the left selects intersection C, which is the next guidance point after intersection B, as the display target. Therefore, in Figure 3(c), the guidance plate 20 displays the direction arrow 21, distance 22, and name 23 for intersection C, and the partial route image 30X displays the map, guidance route 31, and current location mark 32 so that intersection C aligns with the cross mark 37. If a guidance point far from the current location is selected as the display target, the mobile terminal 100 automatically changes the map scale so that the guidance point and the current location mark 32 can be displayed on one screen.

[0043] In this way, by touching the left button 24 and right button 25 on the guide plate 20, or by flicking the guide plate 20 left or right, the user can select any guide point and display the guide plate 20 and the partial route image 30X. Note that in the guide point mode shown in Figures 3(b) and (c), if the user touches the current location button 42, the display screen returns to the current location mode shown in Figure 3(a).

[0044] Next, the display of the guide point list will be explained. In this embodiment, the user can display a guide point list, which is a list of guide points along the guide route. Specifically, in the guide point mode display screen shown in Figures 3(b) and 3(c), the guide point list is displayed when the user touches the list button 27a or flicks the guide plate 20 downwards.

[0045] Figure 4(a) shows an example of a guide point list. Figure 4(a) is an example where there are 6 guide points, 6 guide points can be displayed on one screen in the guide point list, and all guide points can be displayed on one screen. As can be seen by comparing Figures 3(b) and (c) with Figure 4(a), the guide point list is displayed in place of the guide plate 20 and partial route image 30X. Note that the mode bar 40 is also displayed when the guide point list is displayed.

[0046] As shown in Figure 4(a), the guide point list consists of guide point plates 60 that display information for a predetermined number of guide points. Each guide point plate 60 includes a directional arrow 61 indicating the direction of travel, the distance from the previous guide point to that guide point (i.e., the distance between guide points) 62, and the name of that guide point 63. Multiple guide point plates 60 are arranged so that the guide point plates 60 for guide points closer to the starting point are on top, and the guide point plates 60 for guide points closer to the destination are on the bottom.

[0047] As shown in Figure 4(a), when the user touches any of the guide point plates 60 while the guide point list is displayed, the display of the guide point list ends, and the guide plate 20 and partial route image 30X for that guide point are displayed. For example, as shown in Figure 4(a), when the user touches the guide point plate 60 at intersection B, the display screen becomes as shown in Figure 3(b), and when the user touches the guide bar 60 at intersection C, the display screen becomes as shown in Figure 3(c).

[0048] Furthermore, in Figure 4(a), if the user flicks the guide point list upwards, the display of the guide point list ends, and the display screen returns to the display of the guide plate 20 and the partial route image 30X. If, after the guide point list is displayed, the user flicks the guide point list upwards without touching any of the guide point plates 60, the display screen returns to the state before the guide point list was displayed.

[0049] The number of guide points that can be displayed on one screen of the guide point list is predetermined (in this embodiment, it is set to 6). If the number of guide points on the guide route is greater than the number of guide points that can be displayed on one screen, the up button 64 and down button 65 are displayed as shown in Figure 4(b). When the user touches the up button 64, the guide point list scrolls downwards and the guide point plates 60 of guide points before intersection A (closer to the starting point) are displayed. When the user touches the down button 65, the guide point list scrolls upwards and the guide point plates 60 of guide points after intersection F (closer to the destination) are displayed. Note that the user can also scroll the guide point list upwards by flicking downwards instead of touching the up button 64, and can also scroll the guide point list downwards by flicking upwards instead of touching the down button 65.

[0050] Furthermore, if the number of guidance points on the guidance route exceeds the number of guidance points that can be displayed on one screen, a list button 27b is displayed as shown in Figure 4(b). In this case, a flick upwards on the guidance list is interpreted as an instruction to scroll the guidance point list, so a separate list button 27b is provided to close the guidance point list. When the user touches the list button 27b, the display of the guidance point list ends, and the display screen returns to the display of the guidance plate 20 and partial route image 30X as shown in Figures 3(b) and (c). If, after the guidance point list has been displayed, the user touches the list button 27b without touching any of the guidance point plates 60, the display screen returns to the state before the guidance point list was displayed.

[0051] Next, the route display processing according to this embodiment will be described. Figure 5 is a flowchart of the route display processing. This processing is achieved by the control unit 17 of the mobile terminal 100 executing a program stored in the memory unit 13. It is assumed that the guidance route to the destination has been determined and that route guidance is currently being performed.

[0052] During route guidance, the control unit 17 basically displays the current location in the mode as shown in Figure 3(a) (step S10). The control unit 17 determines whether the mobile terminal 100 has arrived at the destination (step S11), and if it has arrived at the destination (step S11: Yes), it terminates the process.

[0053] If the destination has not been reached (Step S11: No), the control unit 17 monitors touch input to the touch panel 120 and determines whether the user has touched the guidance plate 20 (Step S12). If the user has not touched the guidance plate 20 (Step S12: No), the process returns to Step S10, and the display in current location mode continues.

[0054] On the other hand, if the user touches the guidance plate 20 (step S12), the control unit 17 ends the display in current location mode and starts the display in guidance point mode as illustrated in Figures 3(b) and (c) (step S13). The control unit 17 then determines whether or not an instruction to change the guidance point to be displayed has been given (step S14). Specifically, the control unit 17 determines whether the user touches the left button 24 or the right button 25, or whether the guidance plate 20 is flicked left or right. If no instruction to change the guidance point has been given (step S14: No), the process proceeds to step S16.

[0055] On the other hand, if an instruction to change the guidance location is given (step S14: Yes), the control unit 17 changes the guidance location to be displayed (step S15). That is, the guidance location specified by the touch or flick operation described above is displayed in the guidance location mode as shown in Figures 3(b) and (c).

[0056] Next, the control unit 17 determines whether the user has instructed the display of the guide point list (step S16). Specifically, the control unit 17 determines whether the user has touched the list button 27a or flicked the guide plate 20 downwards. If the display of the guide point list has not been instructed (step S16: No), the process proceeds to step S20.

[0057] If the user is instructed to display the guide location list (step S16: Yes), the control unit 17 displays the guide location list as illustrated in Figures 4(a) and (b) (step S17). Next, the control unit 17 determines whether the user has selected a guide location or instructed the user to exit the guide location list (step S18). Specifically, the control unit 17 determines whether the user has touched any of the guide location plates 60 in the guide location list or touched the list button 27b. If the user has neither selected a guide location nor instructed the user to exit the guide location list (step S18: No), the process returns to step S17.

[0058] If the user selects a guidance point or instructs the system to exit the guidance point list (step S18: Yes), the control unit 17 terminates the display of the guidance point list and displays the currently selected guidance point in guidance point mode as shown in Figures 3(b) and (c) (step S19).

[0059] Next, the control unit 17 determines whether the user has given an instruction to end the guidance point mode (step S20). Specifically, the control unit 17 determines whether the user has touched the current location button 42. If the user has not given an instruction to end the guidance point mode (step S20: No), the process returns to step S14, and the display in guidance point mode continues. On the other hand, if the user has given an instruction to end the guidance point mode (step S20: Yes), the process returns to step S10, and the control unit 27 displays the current location mode.

[0060] As explained above, in this embodiment, the name of the intersection and the direction of travel for the next guidance point are displayed during route guidance, and a list of guidance points is displayed in response to user input. Therefore, the amount of information that needs to be displayed on a single screen is reduced, and a display that is easy to see even on a small screen is possible.

[0061] [Differentiation] (Variation 1) As shown in Figure 4(b), if the number of guide points is greater than the number of guide points that can be displayed on one screen of the guide point list, the guide point list can be scrolled by flicking up or down. Generally, when a user flicks, the length of the scroll on the display screen is determined according to the strength and length of the input, and scrolling continues for a while due to inertia even after the user lifts their finger from the screen (this is called "scrolling by inertia"). Here, if a guide point of interest (hereinafter referred to as "guide point of interest") is included among the multiple guide points to the destination, the control unit 17 may stop scrolling when the guide point of interest is included in the display range. That is, if the user flicks with a certain strength, and there is no guide point of interest in the direction of the scroll display, scrolling will be performed for a length corresponding to that strength, but if there is a guide point of interest, scrolling will be forcibly stopped at the position of that guide point of interest. This prevents scrolling by inertia from continuing past the guide point of interest and ensures that the guide point of interest is displayed on the guide point list.

[0062] In this case, points of interest may be displayed in a different manner from other points of interest. For example, points of interest may be highlighted more than other points of interest by changing their color or surrounding them with a thick border. Points of interest are locations that users particularly need to check, such as congested intersections or intersections corresponding to entrances and exits to toll roads.

[0063] (Modification 2) In the above embodiment, the mobile terminal 100 performs route searching to the destination, but instead, a server device connected via the network may perform route searching.

[0064] Figure 6 shows an example of the system configuration related to a modified example. As shown in Figure 6, the mobile terminal 100 is connected to the server device 200 via the network 150. The mobile terminal 100 then provides route guidance by receiving necessary information from the server device 200.

[0065] Specifically, the mobile terminal 100 transmits the user-specified destination, stops, and the mobile terminal 100's current location to the server device 200. Based on this information, the server device 200 performs a route search to determine a route including guidance points and transmits this information to the mobile terminal 100. The mobile terminal 100 provides route guidance according to the route received from the server device 200. [Explanation of Symbols]
