Description

  The present invention relates to a map information display program.

  2. Description of the Related Art Conventionally, an application program for a mobile terminal device that uses a GPS function or an electronic compass function of a mobile terminal device to provide a navigation (hereinafter abbreviated as “navigation”) function using map information to a destination (hereinafter referred to as “navigation”). Hereinafter, it is abbreviated as “application”).

  In the conventional navigation application, the user sets the destination, calculates the route that can be moved in the shortest distance or the shortest time based on the information of the current position obtained from the positioning by GPS, displays the moving route on the map, At the start of navigation, the map was scrolled while guiding the user while positioning the current location as needed to guide the user.

  Here, since the storage capacity of the mobile terminal device varies depending on the model or the memory expansion situation of the user, the map information is stored in a server connected via a communication line, and the mobile terminal device The map information that is scroll-displayed according to the situation such as the current position has been acquired via a communication line as appropriate.

  In the conventional navigation application, the direction is always displayed on the upper side of the map by measuring the direction from the electronic compass or GPS information and rotating the map so that the user can easily understand the route. In some cases, a stereoscopic image of a building or the like that the user should be able to see from the current position is displayed.

  However, even if the above-mentioned display is performed, the user needs to move while always paying attention to the moving direction on the map by comparing the shape of the road on the map and the shape of the building with the actually visible landscape. For users who are not good at reading maps, it may be difficult to trace correctly while moving the route displayed on the map.

  In addition, there is also a problem that it is difficult to see the map displayed on the display unit in the bright outdoors.

  Further, frequent communication of map information slows down the map display depending on the communication status, and stresses the user, and also increases the communication fee due to an increase in the amount of communication.

  Due to the above problems, the conventional navigation application is not necessarily suitable for the purpose of enjoying the movement itself while looking at the scenery like walking around the city.

  Therefore, for example, the navigation program described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-3654) can display only the compass direction from the current position and the longitude and latitude of the destination without displaying a map. It is disclosed.

  Further, in the image distribution apparatus described in Patent Document 2 (Japanese Patent Laid-Open No. 2009-110462), it is disclosed that the direction to proceed from the current position and destination of the client apparatus is displayed as an arrow on the distributed image information. Have

JP-A-2005-3654 JP 2009-110462 A

  However, in the navigation program described in Patent Document 1, since only the direction is displayed, the road condition is not known at all, and there are cases where the moving user is anxious.

  Further, in the image distribution apparatus described in Patent Document 2, the direction is displayed only for a portion where the image information on the route exists, and does not indicate a rough direction to which the user should proceed.

  When walking around a city in an unguided place, many users purchase travel information magazines, etc., first search for the place they want to go to, and then the approximate travel route, for example, a map attached to the information magazine Look for it. However, the purpose is not to trace the exact route, but to enjoy walking around the city itself, and it is not assumed that the user wants to walk or detour freely on the small path that he wants to walk in the field. Conventional navigations that require walking while groping are inappropriate for such applications.

  Therefore, the present invention has been made in view of the problems in the conventional map information display program described above, and it is an object of the present invention to perform minimum map display for a user and navigation that does not require map reading. And

In view of the above problems, a map information display program according to the present invention includes a map information storage unit that stores map information, a current position acquisition unit that acquires a current position at a predetermined interval, an azimuth acquisition unit that acquires an azimuth, and a display. A map information display program executed by an information display terminal having means,
Destination setting function to set the destination,
Based on the current position acquired at a predetermined interval by the current position acquisition means, a surrounding map acquisition function for acquiring a surrounding map of the current position from the map information stored in the map information storage means,

In the first display mode,
A map information display program, comprising: a highlighting function for highlighting the symbol by superimposing a symbol indicating a traveling direction to the destination on the surrounding map.
It is characterized by that.

  According to the embodiment of the present invention, the user can easily confirm the current position and roughly travel to the destination by performing the minimum necessary map display and performing navigation that does not require map reading. Can understand.

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

  FIG. 1 is an example showing a display screen in a first display mode in a map information display program executed by the map information display device.

  Here, the first display mode is a display mode for performing navigation from the current position to the set destination.

  In FIG. 1, the center of the display screen always represents the current position of the user, and the destination is set in the direction indicated by the dotted line from the center of the display screen.

  The displayed surrounding map is rotated and displayed by the electronic compass so that the user's facing direction is always on the display screen. The electronic compass is displayed in the upper right, indicating that the orientation has been measured. Thereby, the user can visually recognize the correspondence between the north indicated by the compass, the map on the display screen, and the traveling direction on one screen.

  In the first display mode, an arrow-shaped representation composed of three arrow heads extending in eight directions from the center of the screen is displayed.

  In the direction from the current position to the destination, the one arrow that is closest in angle is highlighted by coloring.

  Here, the shape of the representation is desirably a shape that can be imaged by the user as the traveling direction. In addition to the illustrated shape, for example, shapes such as an arrow, a triangle, and a pointing mark are conceivable.

  Further, as a method for emphasizing the representation, it is desirable to use an emphasis method that can guide the user intuitively like a turn signal of a car, such as lighting display by coloring, blinking display, and sequential lighting display.

  With this display of symbols, you can enjoy walking around the city with the minimum necessary information such as “the direction of this place” in the same way as when asking people for directions in the city.

  Furthermore, the symbol that blinks may be only one symbol closest to the direction to the destination. For example, if the angle between the direction of the destination and the adjacent symbol is within a certain range, the direction of the destination Depending on the angle created by the symbol and the symbol, both colors may be flashed by changing the intensity of the color.

  These shapes and operations of the representation may be set by the user.

  In the first display mode, the map is displayed with reduced brightness.

  By this map display, the flashing of the above-mentioned symbol superimposed on this map can be made conspicuous even in bright outdoors, and the user can be made unaware of the map. However, this map scrolls as it moves, and you can see that it rotates every time you change the direction of your body, so you can feel that you are being guided on the map, and you are moving with peace of mind. be able to.

  In the first display mode, the accompanying information of the destination can also be displayed superimposed. The map information includes accompanying information regarding a registration point that can be selected as a destination, and for example, the photograph data of the destination can be displayed as shown in the figure. It is also possible to display neighboring information other than the destination. Furthermore, by touching the displayed photograph, other information such as the business hours of the destination store may be displayed, or detailed information may be displayed in a pop-up.

  FIG. 2 is an example showing a display screen in the second display mode in the map information display program executed by the map information display device.

  Here, the second display mode is a display mode until the destination is set. Compared to the dark display of the map in the first display mode, the map display is performed with the normal brightness in the second display mode.

  In FIG. 2, a mark indicating the current position is displayed on the display screen. In the second display mode, the user performs general map operations such as moving, enlarging / reducing the displayed map by performing operations such as dragging, flicking, pinching in / pinching out on the display screen. be able to.

  In the second display mode, a plurality of pieces of information registered at the lower part of the display screen are displayed together with the distance from the current position.

  The user can tap one destination and select “view details” and “go here”. Here, when “go here” is tapped, navigation to the destination in the first display mode described above can be started.

  FIG. 3 is an example showing a display screen of the detailed information of the destination in the second display mode.

  In the second display mode, when a destination is tapped and then "View details" is tapped, the details of the destination shown in FIG. 3 are popped up. FIG. 3 is an example of displaying detailed information of a store. The detailed information displayed here is composed of a plurality of accompanying information for the destination.

  In FIG. 3, this detailed information displays accompanying information such as a destination name, a photograph, an introduction, and an address. The accompanying information displayed in the first display mode described with reference to FIG. 1 may be photographic data or an introduction sentence.

  These accompanying data can be included in the map information downloaded from the map server from the beginning, and can also be obtained separately from the Internet. For example, the introduction text of the old place mark may be included in the map information from the beginning because the update frequency is relatively low. For example, the parking space availability may be updated from the Internet as appropriate.

  In the second display mode, information published in a travel information magazine is digitized and provided to the user. The user can obtain the same effect as scraping information published in a travel information magazine based on the current position. The user can obtain detailed information on the destination in the second display mode, and at the same time, can move to the first display mode with a simple operation and enjoy walking around the city.

  The user can return to the display screen shown in FIG. 2 again and start navigation by tapping the “Close” button in the upper right.

  FIG. 4 is an example showing a display screen for explaining the second navigation method.

  Some users prefer a display close to a paper map with north fixed over the navigation in the first display mode described above. In that case, the second navigation method shown in FIG. 4 can be selected by setting.

  In FIG. 4, the map is not rotated around the current position of the user, but a radial display is rotated in the direction of the destination. In this navigation, since the traveling direction does not match the upper direction of the map on the display screen, it is assumed that the user walks while viewing the map, and the map is not displayed darkly as in the first display mode.

  Next, a hardware configuration, a software configuration, and an operation flow for providing the display screen as described above will be described below.

  FIG. 5 is an example showing an overall system diagram including a map information display device on which the map information display program according to the present invention is mounted.

  In FIG. 5, the system 1 includes a plurality of mobile base stations 20 (20a, 20b, 20c, etc.), a network 30, a map server 40, and a GPS satellite 50, including the map information display device 10.

  The map information display device 10 includes a CPU 1001, a RAM 1002, a ROM 1003, a main control unit 100, a GPS positioning unit 101 that performs positioning by supplementing a signal from a GPS (Global Positioning System) satellite 50, and an azimuth measuring unit 102 that measures an orientation. , Operation / display means 103 for providing a user interface, voice input / output control means 104 for controlling voice input / output, communication control means 105 for controlling communication with a terrestrial base station, communication by a wireless LAN (Local Area Network) A wireless LAN control unit 106 for controlling, a call control unit 107 for controlling a call, an external memory control unit 108 for controlling an external memory card, a camera control unit 109, and a non-contact communication control unit 110 are provided.

  The main control means 100 includes a CPU 1001, a RAM 1002, and a ROM 1003, and controls the entire apparatus including the above-described various means in the apparatus and execution of an application described later.

  The GPS positioning means 101 supplements radio waves from a plurality of GPS satellites 50 orbiting the earth, can calculate the distance from each satellite from the difference in reception time of radio waves from each satellite, and measures the current position. be able to.

  The communication control means 105 controls communication with a plurality of base stations 20. Each base station 20 is connected to the Internet, and the communication control means 105 also performs data communication control via the Internet 30. This communication includes communication of positioning information from the base station 20 in addition to data communication. The positioning information from the base station 20 is measured by the distance from each base station, separately from the radio wave from the GPS satellite.

  The wireless LAN control means 106 controls wireless LAN communication at the access point 21 of the wireless LAN. Each access point is assigned a unique address, and radio waves including this unique address can be supplemented even if the Internet cannot be connected through the access point. The current position can be specified. It can be used even when the GPS radio wave cannot be supplemented in an underground shopping center.

  The call control unit 107 controls outgoing calls and incoming calls when the map information display device 10 is used as a mobile phone for a voice call.

  The external memory control unit 108 controls a memory card that can be attached to and detached from the map information display device 10. The memory controlled by the external memory control unit 108 can be mounted by a non-volatile memory card 1081 such as a flash memory. However, the usage method is the same as the ROM used in the main control means 100, and is the difference between the internal memory and the external memory. Therefore, for example, both map information can be stored in the memory.

  The camera control unit 109 controls the camera 1091 provided in the map information display device 10. Image processing of still images or moving images taken by the camera is performed, for example, two-dimensional barcode recognition processing is performed.

  The non-contact communication control unit 110 controls an IC chip that performs non-contact communication. In addition to being used as a payment function using a non-contact type IC chip, for example, it can also be used as an information input function instead of map information or the above two-dimensional barcode.

  For positioning of the current position, in addition to independent positioning for positioning the current position by supplementing the signal from the GPS satellite 50 with the GPS positioning means 101, communication of positioning information with the base station 20 by the communication control means 105 and wireless LAN An assist type GPS that measures the current position by the control means 106 may be used.

  You may make it select a positioning system with the map information display program mentioned later. For example, the assisted GPS can be used in a range where radio waves from a base station or a wireless LAN reach, and single positioning can be used in a place where radio waves from the base station or the wireless LAN do not reach.

  There are a plurality of base stations 20 (20a, 20b, 20c, etc.), and each communicates with the map information display device 10 through the communication control means 105. The base station is connected to the map server 40 via the Internet 30.

  The map server 40 includes a map database 400. A plurality of pieces of map information are stored in the map database 400, and various map data can be provided in response to an acquisition request from the map information display device 10. Note that the map server 40 may include an authentication unit and a billing unit (not shown). The map server 40 can provide information only to the map information permitted by the authentication means or the billing means, or only to the permitted map information display device 10.

  FIG. 6 is an example showing an overall view of the software configuration of the map information display device in which the map information display program is installed.

  In FIG. 6, the software 6 of the map information display device is hierarchized into layers, and includes layers of a kernel 61, a library 62, a framework 63, and an application 64.

  The kernel 61 is a core part of an operating system (OS) that performs memory management and overall system monitoring.

  The library 62 is a part of a program that allows a specific function of the map information display device 10 to be used from the upper layer application 64, and is used as a part of the application 64 when the application 64 is executed.

  The framework 63 is a template part for developing an application, and general functions such as the operation of the display operation unit executed by the application and the function using the library 62 are collectively provided as an API (Application Program Interface). To do. This framework can increase the efficiency of application development.

  The application 64 is various applications developed using the framework 63, and is installed and used by the user as appropriate.

  FIG. 7 is an example showing the layer details of the application 64.

  In FIG. 7, the map information display program 7 of the present invention belongs to this layer. In addition to this, a plurality of applications such as application A, application B, and application C can be mounted on this layer.

  Application installation, uninstallation, activation, and the like can be performed in units of applications, and the map information display program according to the present invention can be installed by, for example, downloading from an application server (not shown).

  Although the software configuration described above may vary depending on the model of the map information display device, a configuration capable of mounting an application is required.

  FIG. 8 is an example showing details of the map information display program 7.

  In FIG. 8, the map information display program 7 includes a map information acquisition function 71, a destination setting function 72, a surrounding map information acquisition function 73, a rotation function 74, and a highlight display function 75.

  The operation of the map information acquisition function 71 will be described with reference to FIG.

  FIG. 9 is an example of a flowchart for explaining the operation of the map information acquisition function 71.

  In FIG. 9, the user reads a two-dimensional barcode published in the purchased travel information magazine with the camera 1091 (S100).

  For example, when the name of the travel magazine is “walking around Kamakura Koto”, the map information to be acquired is specified by this two-dimensional barcode. The two-dimensional barcode can be associated with a unique standardized book number so as to correspond one-to-one with a travel magazine. In that case, even for the same magazine name, the data to be acquired can be changed for each publication year, and it becomes possible to provide a service linked to the purchase of the magazine.

  Next, the communication control means 105 accesses the map server 40 via the Internet 30. The two-dimensional barcode specifies map information of the corresponding “walk around Kamakura Koto” from a plurality of map data stored in the map server 40, downloads it (S101), and stores it in the memory card 1081. (S102) A list of saved maps is displayed so as to be selectable (S103).

  Next, operations of the destination setting function 72 and the surrounding map information acquisition function 73 in FIG. 8 will be described with reference to FIG.

  FIG. 10 is an example of a flowchart illustrating operations of the destination setting function 72 and the surrounding map information acquisition function 73.

  In FIG. 10, a plurality of map information downloaded from the menu upon activation of the application is listed (S200). For example, the “Kamakura ancient city walk” downloaded earlier is displayed in a list on the display screen together with “Kyoto walking”, “Tokyo underground walk”, “Yakushima trekking”, etc. that have already been downloaded.

  When the user selects “walk around Kamakura Koto” here and displays a map (S201), the surrounding map information acquisition function 73 is measured by the GPS positioning means 101, the communication control control means 105, or the wireless LAN control means. The current position is notified from the main control means 100 (S202), and it is checked whether or not the current position is within the display range in the selected map information (S203).

  If it is within the display range, a map around the current position is acquired from the memory card 1081 storing the map information, and a map centered on the current position is displayed on the display screen (S204). After the display, the process proceeds to A described in FIG.

  On the other hand, if it is outside the display range, a notification that the current position could not be acquired is sent (S205), and a map of the set initial position is displayed (S206). This initial position may be, for example, a railway station or a bus stop.

  The display screen displayed in step S204 is the second display mode described with reference to FIG.

  Next, operations of the rotation function 74 and the highlight display function 75 in FIG. 8 will be described with reference to FIG. 11 together with FIG.

  FIG. 11 is an example of a flowchart illustrating operations of the rotation function 74 and the highlight display function 75.

  In FIG. 11, it continues from the flowchart displayed by A of FIG. In A, the display is centered on the current position or the initial position where the current position is not displayed, but the subsequent operations are the same.

  It is determined whether or not “go here” in FIG. 2 has been tapped and selected (S300). If selected, the display shifts to the first display mode shown in FIG. Is darkened, and eight-direction arrows “front, rear, left, right, left front, right front, left rear, right rear” are superimposed on the map and displayed on the display screen (S301).

  Next, the current position is measured from the measurement result of the GPS positioning means 101 and the like, the orientation measurement result by the orientation measurement means 102 is acquired (S302), and the map is rotated according to the earned orientation (S303). At this time, as shown in FIG. 1, the compass in the upper right of the display screen is aligned with the correct orientation, and a dotted auxiliary line is displayed in the destination direction. In the case of FIG. 1, assuming that the user has the map display device 10 substantially horizontally in front of the body, the user is facing substantially east and the traveling direction of the destination is approximately west-northwest. Thus, the arrow in the “left” direction closest to west-northwest blinks like a blinker, indicating the direction in which the user should proceed (S304).

  It is determined whether an interval time for measuring the azimuth or the like has elapsed (S305), and the processing of S207 to S209 is performed at a predetermined interval.

  The navigation in the first display mode is terminated by arrival at a destination (not shown) or by a stop instruction in the middle. For example, when “Menu” in FIG. 1 is pressed, the screen may return to FIG. 2 or may return to a map selection screen (not shown).

  As described above, the current position is determined by the GPS satellite 50 using the GPS positioning unit 101, the base station 20 using the communication control unit 105, or the access point using the wireless LAN control unit 106. Or, assist type positioning combining them is possible, but the positioning means can be changed by selecting a map. For example, if the selected map is “Tokyo underground walk”, the radio wave from the GPS satellite 50 cannot be supplemented, but positioning using the base station 20 or a wireless LAN access point is possible, and many When “Yakushima Trekking”, which is the so-called “out of mobile range”, is selected, only positioning by the GPS satellite 50 is possible, so the positioning method may be switched when the map is selected.

  Note that the current position measurement and azimuth measurement use measurement means such as an electronic compass built in the map information display device 10, so that battery consumption increases. For this reason, for example, by setting a wide measurement interval, battery consumption can be suppressed.

  If “go here” is not selected in S205, the detailed information depends on whether or not the details of the destination are viewed in the second display mode, as shown in FIGS. 2 and 3 (S310). Is displayed (S311), and when it is closed (S312), the display returns to the display of FIG.

  In FIG. 1, only the “left” arrow is blinked. For example, the “left front” arrow is blinked lighter than the “left” arrow, and the traveling direction is slightly forward than the “left” direction. You may display as there is. In that case, if the destination is directed to the middle position between the “left” and “front left” arrows, it may blink at the same brightness to express the middle direction that cannot be compensated for in the eight directions. good.

  FIG. 12 is an example showing details of accompanying information included in map information.

  In FIG. 12, the map information of “walking around Kamakura Koto” includes accompanying information registered on the map data. For example, “registered location name”, “latitude and longitude”, “address”, “phone number” , “Guidance text”, “Current information”, “Photo data”, and the like. This accompanying information may be added by the user as appropriate. For example, it is possible to add information indicating that the user has already visited, a comment, and a photo. In addition, the registration point itself can be newly registered by the user.

  Further, the accompanying information can be stored in a server (not shown) through the network as information dedicated to the user.

  Furthermore, you may link this application with other SNS (social networking service). For example, user reviews and food photos are shared.

  The destination shown in FIG. 2 may be selected and displayed by selecting the distance from the current position, the direction, the category, and the like.

  In FIG. 1, a photograph of the selected destination is displayed during navigation, but for example, an introduction sentence other than the photograph may be displayed. Information other than the destination, for example, on the navigation route or around the destination may be displayed. Further, the introduction sentence may be output as voice through the voice input / output control means.
