[Embodiment]
Hereinafter, a first embodiment of the present invention will be described using FIGS. 1 to 5.

  FIG. 1 shows a system configuration diagram of a map display system 10 including a terminal device 200 in which a control program (hereinafter referred to as a map display application) according to the present embodiment is installed. As shown in FIG. 1, the information processing apparatus 100 and the terminal device 200 (collectively, the terminal devices 200A to 200D are referred to as the terminal device 200) are set to be mutually communicable via the network 300 such as the Internet or a dedicated line. The map display system is configured by In this map display system, distribution of various applications such as a map display application is performed from the information processing apparatus 100 to the terminal device 200.

  FIG. 2 is a block diagram of the information processing device 100 and the terminal device 200.

  The information processing apparatus 100 is a server computer, and as shown in FIG. 2, a control unit 110 including a CPU (not shown) and a memory (not shown), a communication unit 140 for connecting to the network 300, and information. An input unit 120 for receiving an operation from the manager of the processing apparatus 100, and a storage unit 130 storing an application to be distributed, map information, content data, and the like are provided.

  Map information means information for drawing a map. For example, the map information includes map images, information of latitude and longitude, and the like. Content data refers to information displayed superimposed on a map. For example, content data includes event information, store information, facility information, traffic regulation information, icons, note information, and the like. Further, the content data is preferably information linked to the mesh.

  A mesh is a plurality of divided areas obtained by dividing a map based on latitude and longitude. In the present embodiment, although the mesh is described as a square area, the present invention is not limited to this, and the shape and size of the mesh divided area can be appropriately set according to the specification and design. For example, the shape of the mesh can be an area surrounded by a polygon such as a quadrangle, a hexagon, a rhombus, or a curve such as a circle. Also, the size of the mesh may not be constant. For example, the size of the mesh can be set large if the user wants to specify a mesh frequently staying, while the size of the mesh can be set small if it is desired to specify a store or the like frequently visited by the user. Also, for example, the mesh in the urban area may be made smaller (more finely). In addition, the size of the mesh may be changed for each area according to the demographic information (for example, the mesh of the area with a large population may be reduced), or the size may be set based on the classification of municipality, residential area type, etc. .

  The information processing apparatus 100 includes the distribution unit 111 as a functional unit in the control unit 110, and upon receiving a download request from the terminal device 200, authenticates the request source and distributes an appropriate application from the distribution unit 111. Is desirable.

  The terminal device 200 is a portable terminal device that can be carried by the user and has a function of uploading, at a predetermined time interval or based on the user's input, the position information at which the current position has been measured. Specifically, for example, a mobile phone, a smartphone, a notebook PC, a PDA and the like can be mentioned. In the present embodiment, the user is described as using the drive recorder application using the terminal device 200. However, the terminal used by the user does not necessarily have to be portable. Good.

  As shown in FIG. 2, the terminal device 200 includes a main control unit 210, an input unit 220, a storage unit 230, a communication unit 240, and a display unit 250.

The main control unit 210 includes an arithmetic processing unit 211 such as a CPU and an MPU, and a memory (not shown).
Is equipped. The arithmetic processing unit 211 operates various functional units by executing a program stored in a memory (not shown) based on various inputs. This program may be stored in an external memory such as microSD, or may be distributed via the network 300 and installed in the terminal device 200. The memory (not shown) stores data and the like required for processing by the system of the terminal device 200, including an operating system (OS).

  The input unit 220 receives an instruction for moving the map information displayed on the display unit 250. Specifically, the input unit 220 indicates a button, a touch panel, a mouse, a keyboard, and the like, and is configured to receive an operation from the user.

  The storage unit 230 is configured by a storage medium such as a RAM, and is for storing data related to an application downloaded by the user, an image file, an audio file, and the like. Storage unit 230 is not limited to one incorporated in terminal device 200, and may be, for example, an external memory such as microSD.

  The communication unit 240 refers to one for connecting the terminal device 200 to the network 300, and the display unit 250 refers to a liquid crystal screen or the like that displays an image on the terminal device 200.

  The map display application can be installed in the arithmetic processing unit 211 to function as an acquisition unit 2111 and a determination unit 2112.

  The acquisition unit 2111 acquires content data related to the map information included in the first display area displayed on the display unit 250. For example, the acquiring unit 2111 desirably acquires content data in mesh units. Specifically, the acquisition unit 2111 is configured to acquire, from the information processing apparatus 100, content data related to a mesh having a portion overlapping the first display area. For example, when transmitting the content data acquisition request to the information processing apparatus 100, the acquisition unit 2111 selects the minimum latitude longitude and the maximum latitude longitude among the latitude longitudes corresponding to the coordinates included in the first display area. It is desirable to send together. Thus, the information processing apparatus 100 calculates the first display area from the received minimum and maximum latitude and longitude, and specifies a mesh having a portion overlapping the area. The information processing apparatus 100 can transmit content data related to the identified mesh to the acquisition unit 2111.

  The acquiring unit 2111 preferably acquires map information from the information processing apparatus 100 before acquiring content data. Acquisition of map information can be performed using existing technology.

  FIG. 3 is a diagram schematically showing the range of map information related to the content data acquired by the acquisition unit 2111. As shown in FIG.

Region R60 schematically shows a part of the map information divided into meshes.
The area R611 is an area of the map displayed on the display unit 250. A point P13 corresponds to the minimum latitude and longitude included in the area R611, and a point P12 corresponds to the maximum latitude and longitude included in the area R611.

  The acquisition unit 2111 transmits an acquisition request for content data to the information processing apparatus 100. At this time, the acquisition unit 2111 also transmits the latitude and longitude corresponding to the point P12 and the point P13. The information processing apparatus 100 that has received the acquisition request calculates a region R611 displayed on the display unit 250 from the latitude and longitude of the point P12 and the point P13. Then, the information processing apparatus 100 transmits a content data by specifying a mesh having a portion overlapping with the region R611. In the example of FIG. 3, the meshes 53 to 56, 68 to 71, 83 to 86, 98 to 101, 113 to 116, 128 to 131, and 143 to 146 have mesh portions overlapping with the first display region R611. It is. The information processing apparatus 100 transmits the content data related to these meshes to the acquisition unit 2111.

  The acquisition unit 2111 further relates to the map information included in the second display area displayed on the display unit 250 after the movement when the determination unit 2112 described later determines that the input of the movement instruction is completed. Reacquire content data.

  The determination unit 2112 determines whether the input of the movement instruction has been completed. Specifically, the determination unit 2112 completes the input of the movement instruction when the further movement instruction is not received until the predetermined period elapses after the input unit 210 receives the movement instruction from the user. It is determined that For example, when the user inputs an instruction using a mouse, the user can move the display range of the map by dragging (mouse down) the map using the mouse and moving the cursor while dragging. Move the display range (mouse move) and drop the map when any point is displayed (mouse up). A series of operations from this drag to the drop are taken as one movement instruction. The user inputs this movement instruction until the display range of the map moves to the place where the user wants to display it. A plurality of movement instructions can be input until the input of movement instructions is completed.

  The determination unit 2112 measures an elapsed time from the drop (mouse-up), and determines whether the measured time (hereinafter referred to as a timer value) exceeds a threshold. If the user drags the map again and mouse-down occurs before the timer value exceeds the threshold, the timer value is reset. When the timer value exceeds the threshold, the determination unit 2112 determines that the input of the movement instruction has been completed.

  Also, for example, when the user inputs an instruction using the touch panel, the user taps a finger on the touch panel, and moves the display range of the map by moving the finger in contact with the touch panel. The determination unit 2112 determines whether the timer value after the user's finger has left the touch panel has exceeded a threshold. The timer value is reset when the user taps a finger on the touch panel again and a movement instruction is input before the threshold value is exceeded. Also in the case of the input by the touch panel, the determination unit 2112 determines that the input of the movement instruction is completed when the timer value exceeds the threshold.

  Furthermore, it is desirable that the determination unit 2112 determine this threshold based on the line speed of the network 300 to which the terminal device 200 is connected.

  For example, it is possible to set in advance a target value from the completion of the input of the movement instruction until the content data is displayed on the display unit 250. It is desirable that this target value be a time for which the user can wait without stress until content is displayed, for example, about 3 seconds. The determination unit 2112 calculates a standby time from the target value and the line speed, and uses the standby time as a threshold.

  Specifically, the communication unit 240 detects the current type of communication line, and notifies the determination unit 2112 of the detected result. Examples of the line type include a 3G line, an LTE line, and an optical line. The determination unit 2112 calculates the threshold by weighting the target value based on the notified type of line.

  For example, a case where the target value is 3 seconds is taken as an example. In the case of LTE or an optical line, since the line speed is high, even if the standby time is long, content data can be acquired and displayed before the time that is the target value passes. Therefore, for example, it is possible to set the weighting to 0.23 and set the threshold value to 0.69 seconds, which is the product of the target value 3 seconds.

  On the other hand, in the case of the 3G line, the line speed is slower than that of the LTE line and the optical line, and therefore the standby time needs to be short in order to acquire and display content data before the time as the target value passes. Therefore, the threshold value is 0.3 seconds, which is the product of the target value and a value smaller than 0.23, for example, 0.1. The threshold value for each line may be calculated in advance and held in the table of the storage unit 230. In this case, the determination unit 2112 can select a threshold according to the type of line by referring to the table. The function of the determination unit 2112 can also be provided on the information processing apparatus 100 side.

  As described above, only the map information is displayed while the movement instruction is input, and the acquisition of the content data is not performed, whereby the communication amount can be suppressed. On the other hand, it is desirable to acquire map information each time there is a movement instruction of the map range from the user. This makes it possible to grasp which map the user is currently displaying, even while moving the map.

  FIG. 4 is a view schematically showing the state when the display range of the map is moved by the operation of the user. In FIG. 4, a region R60 schematically shows the map information divided into meshes. An area R611 indicates a first display area, and an area R612 indicates a second display area.

  A point P13 corresponds to the minimum latitude and longitude included in the region R611, and a point P12 corresponds to the maximum latitude and longitude included in the region R611. Furthermore, a point P23 is a point corresponding to the minimum latitude and longitude included in the region R612, and a point P22 is a point corresponding to the maximum latitude and longitude included in the region R612.

  An arrow T indicates a time axis. The time t1 indicates the time when the user U starts inputting an instruction to move the display range of the map by tapping a finger on the touch panel. The time t2 indicates the time when the user U releases the finger from the touch panel, the time t3 indicates the time when the user U again taps the finger on the touch panel, and the time t4 indicates the time when the user U again removes the finger from the touch panel. Furthermore, time t5 indicates a time obtained by adding a threshold to time t4.

  A period from time t1 to time t2 and a period from time t3 to time t4 indicate a moving period while the finger of the user U is in contact with the touch panel. Further, a period from time t2 to time t3 indicates a period shorter than the threshold.

  At time t2, when the finger is separated from the touch panel, the determination unit 2112 measures a timer value from time t2 and determines whether a threshold is to be passed. In this example, since the user U again taps the finger on the touch panel before the timer value passes the threshold (time t3), the determination unit 2112 determines that the movement instruction is not completed, and resets the timer value. Do. Next, at time t4, when the finger is separated from the touch panel again, the determination unit 2112 measures a timer value from time t4 and determines whether or not the threshold value is exceeded. In this example, since there is no tap from the user U again until time t5 when the timer value passes the threshold value, the determination unit 2112 determines that the move instruction is completed. At this time, the acquiring unit 2111 transmits the coordinates of the point P23 and the point P22 corresponding to the minimum and maximum latitude and longitude of the second display area R612 after movement to the information processing apparatus 100, and reacquisition of content data Do. The arithmetic processing unit 211 superimposes the reacquired content data on the map information included in the second display area, and causes the display unit 250 to display the same.

  As described above, when the determination unit 2112 determines that the move instruction is not completed, the reacquisition of the content data by the acquisition unit 2111 is suppressed, so that the content data is reacquired each time the move instruction is issued. It is possible to reduce the amount of communication between the information processing apparatus 100 and the terminal device 200.

  Next, the flow of the map display process of the terminal device 200 will be described with reference to FIG. Note that each processing step included in the flow of processing described below can be arbitrarily changed in order or can be executed in parallel, as long as no contradiction occurs in the processing content. Step may be added. In addition, while the steps described as one step can be divided into a plurality of steps and executed for convenience, those described into a plurality of steps for convenience can be grasped as one step.

  The user operates the terminal device 200 to activate the map display application. When the application is started, the arithmetic processing unit 211 sets a flag to 1 (S100).

  Next, in order to display a map on the display unit 250, the acquisition unit 2111 first transmits an acquisition request for map information to the information processing apparatus 100, and receives map information from the information processing apparatus 100 (S101). . Next, the acquisition unit 2111 confirms the value of the flag (S102). If the flag is 0 (S102: YES), the acquisition unit 2111 does not acquire content data, and displays a map on the display unit 250 using already acquired content data (S104).

  On the other hand, when the flag is 1 (S102: NO), the acquisition unit 2111 transmits an acquisition request for content data for the first acquisition target area to the information processing apparatus 100, and acquires content data (S103). ). At this time, the acquisition unit 2111 transmits the acquisition request together with the minimum latitude longitude and the maximum latitude longitude among the latitude and longitude corresponding to the coordinates included in the first display area.

  The information processing apparatus 100 having received the content data acquisition request calculates the range of the first display area from the received minimum latitude and longitude and the maximum latitude and longitude, and identifies a mesh having a portion overlapping with the range. , Send content data related to the identified mesh.

  When the content data transmitted by the information processing apparatus 100 is received, the content data is superimposed on the map information received in advance by the arithmetic processing unit 211, and the map is displayed on the display unit 250 of the terminal device 200 (S104). If the user moves the display range of the map by further operating the terminal device 200 (S106: NO) without ending the application (S105), the determination unit 2112 measures the timer value and whether the threshold value has passed It is determined whether the input of the movement instruction has been completed based on (S107). If it is determined that there is a move instruction further and the input of the move instruction is not completed before the threshold is exceeded (S107: NO), the arithmetic processing unit 211 sets the flag to 0 and recursates in S101. . On the other hand, when there is no move instruction until the threshold is passed, and the determination unit 2112 determines that the input of the move instruction is completed (S107: YES), the arithmetic processing unit 211 sets a flag to 1, and recursive in S101. Do.

  The processes from S101 to S109 are repeatedly executed until the user ends the application (S105: YES).

  By this, when the map display application is activated, the flag is set to 1, so that content data is acquired. On the other hand, when the display range of the map is moved by the operation of the user, the value set in the flag differs depending on whether the timer value exceeds the threshold. Therefore, when a move instruction is further issued before the threshold has elapsed, the flag is set to 0, and thus the content data is not reacquired. On the other hand, when the threshold value has passed, the flag is set to 1, so that content data is re-acquired.

  As described above, it is possible to reduce the amount of communication by not acquiring content data again until the input of an instruction for moving the display range of the map from the user is completed.
