Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Mechanism of display processing of the present invention]

  Usually, in a map display system, the user first obtains rough information by looking at the entire screen, and then scrolls the object of interest (for example, POI (Point of Interest) icon, label, landmark, etc.). It is thought that there are many usage forms that are displayed in the center of the screen. For this reason, it is considered that a form in which more information is obtained on the entire screen and accurate information is obtained near the center of the screen is preferable.

Therefore, in the present embodiment, a real parameter “object height” is newly assigned to each object. The “object altitude” is a value unrelated to the actual altitude such as a landmark arranged in the map data. Hereinafter, in order to avoid redundant description, “object altitude” is abbreviated as “altitude”.
Then, as if the altitude is higher, the object at a position away from the center of the screen is apparently shifted to the outside of the screen as if it was taken with a camera from the map. Here, the displacement of the display position is set to 0 (reference position information) near the center of the screen, and increases as the distance from the center of the screen increases. That is, the display position is determined according to the following equation (1).
Display position = original display position + (deviation of the original display position from the center of the screen x altitude)
... (1)

  By applying the above formula (1), the original position of the object can be accurately displayed near the center of the screen. Here, the original position of the object means a position where the latitude and longitude information defined in the object and the latitude and longitude information on the map data match and are displayed. On the other hand, if the object of interest is moved to the outside of the screen by scrolling, the object that overlaps in the vicinity of the center of the screen can be displayed outside the screen in a state where the overlap is eliminated due to the shift. The altitude is 0 on the map surface and a positive value on the front side of the screen. Further, although the vicinity of the center of the screen is determined as the reference position information, it is of course possible for the user to arbitrarily determine it.

Next, an example in which an object is displayed while being shifted by scrolling will be described with reference to FIG. FIG. 1A shows a display example of the map before scrolling, and FIG. 1B shows a display example of the map after scrolling.
Note that user operations such as scrolling operations are performed by a device having a display via a mouse, keyboard, numeric keypad, etc. (in addition to a personal computer, a portable terminal, a mobile phone, a smartphone, a TV, a game machine or recorder connected to the display) Etc.), and any device having a display with a touch panel may be input to the computer via the touch panel. A device having a display inputs, as an input event, a physical event that a user performs through an input device by a function of a basic program such as an OS, and realizes processing based on the input event by a function of a program unique to the present invention.

  For example, in the map display example shown in FIG. 1A, it is assumed that the heights of the objects A1 and A2 are set higher than the objects A3 and A4. When the user scrolls the map screen shown in FIG. 1A upward, the display transitions as shown in FIG. That is, the object A1 and the object A2 apparently move downward as compared with the object A3 and the object A4 having a low altitude, so that the object A3 and the object A4 buried in the map of FIG. 1A can be seen. .

  2A is a schematic diagram when the display example of the map of FIG. 1A is viewed from the side, and FIG. 2B is the schematic view of the map display example of FIG. FIG. As can be seen from these figures, as shown in FIG. 2A, before scrolling, a map as if it was taken with a camera is displayed almost vertically. can not see. On the other hand, as shown in FIG. 2B, after scrolling, a map as if it was taken with a camera from an oblique direction is displayed, and the objects 3 and 4 having a low altitude can be seen.

  As described above, the user can obtain accurate position information of an object at the center of the screen, and at the same time, can obtain information that has been buried by scrolling the screen even when there are overlapping objects.

  In the present embodiment, the object includes a label (keyword) representing the characteristics of the store and a rectangular icon surrounding the label.

[How to set the altitude]
Next, a method for setting an altitude for an object will be described.
(How to set altitude using random numbers)
The altitude can be set for each object using a random number. While this method is simple and can execute processing at high speed, in many cases, good results can be obtained. However, when almost the same altitude is assigned to the overlapping objects, the overlapping objects cannot be seen even if the screen is scrolled.

(How to set altitude while stacking objects)
Arrange the objects so that they are stacked on the map in chronological order of registration. Then, when placing the altitude, the altitude is set so as to take a distance greater than or equal to a predetermined value from an object below or near the object. Specifically, as shown in FIG. 3, margins (blanks) are set for the arranged objects in the screen depth direction and the horizontal direction, and the lowest altitude that does not touch the margins of other objects is assigned.

  In the example of FIG. 3, five objects A1 to A5 are arranged, and a schematic diagram when they are viewed from the side is shown. For example, the height of the object A1 is set to a value obtained by adding a screen depth direction margin to the highest height among the objects A2 to A5 overlapping the object A1, that is, the heights of the objects A2 and A3. As a result, as shown in FIG. 3, a gap corresponding to the margin in the screen depth direction is generated between the object A1 and the objects A2 and A3.

  Here, the horizontal margin is indispensable for setting an appropriate interval. For example, as shown in FIG. 4, when a margin is not set in the horizontal direction, an altitude that is one step lower is assigned to the object A1 that is at the top in FIG. This is because A5 is buried and visibility is lowered.

  Note that the margin to be allocated is not a fixed length, but a predetermined ratio (%) with respect to the smaller size of the size of the object in the vertical direction and the horizontal size of the screen. That is, since an object having a large size has a large margin, an altitude sufficiently separated from the lower object is set, and it is possible to prevent the lower object from becoming difficult to see.

  As described above, in the method of setting the altitude while stacking objects, the display order can be maintained in the order in which the objects are registered, and an appropriate interval from other objects can be ensured. Therefore, when the screen is scrolled, the buried object is easy to see. This embodiment will be described in detail using a method of setting the altitude while stacking these objects.

[Embodiments of the present invention]
FIG. 5 is a diagram showing a configuration example of an information display system as an embodiment of the present invention.

  As shown in FIG. 5, the information display system is configured by connecting a mobile terminal 1 and a map distribution server 2 to each other via a network 3. In addition, the number of the portable terminals 1 is arbitrary, and it is of course possible to provide a plurality.

The mobile terminal 1 has a CPU (Central
Processing Unit), ROM (Read Only
Memory), RAM (Random Access)

  The control unit 11 includes a CPU that executes a program, and a RAM, ROM, and the like that store program instructions or data. The control unit 11 controls each unit according to a program stored in the storage unit 12 or the like.

  The storage unit 12 stores a program executed by the control unit 11, data necessary for program execution, an OS (Operating System), and the like. The storage unit 12 stores map data received from the map distribution server 2 and information related to objects registered by the user on the map. The information regarding the object includes a label (a name representing the characteristics of the store), a label size (an area of an icon determined from the number of characters in the label), and registered position information of the label.

  The operation reception unit 13 receives an operation by a user using the input unit, and transmits the operation content to the map distribution server 2 via the communication control unit 15. The operation content includes, for example, a map browsing request, screen scroll, object registration, and the like as shown in FIG.

  The object registration is, for example, when a user wants to register on the map, the user sets (registers) an object including icons and labels and its position information (location) for the store. The icon has a rectangular shape surrounding a label (keyword) representing the characteristics of the store. In addition, a plurality of types of tags (for example, ramen, pasta, bread, liquor, vegetables, meat, etc.) relating to the store are prepared in advance in the mobile terminal 1, and the user selects a tag imaged from the tags. The label can be given to the store. Thereby, the “city characteristics” imaged by the user can be reflected on the map.

  Note that the object registration is not only performed by the user, but may be automatically given by the map distribution server 2 by analyzing restaurant information posted on a gourmet site, for example. The object registration method is not particularly limited.

  The display control unit 14 reads map data from the storage unit 12 and displays the map data on the display screen in response to a map browsing request from the user received by the operation receiving unit 13.

  The communication control unit 15 includes a communication control device, a communication port, and the like, and is a communication interface that mediates communication between the portable terminal 1 and the network 3. Between the portable terminal 1 and the map distribution server 2 via the network 3. Control communication.

  The mobile terminal 1 is, for example, a smartphone, an iPhone (registered trademark), a mobile phone with a camera, an ipad (registered trademark), a portable personal computer, or the like.

  The map distribution server 2 is a computer on which a CPU, ROM, RAM, HDD, etc. are mounted, and has at least the functions of a control unit 21, a map data storage unit 22, an altitude calculation processing unit 23, a database 24, and a communication control unit 25. Have.

  The control unit 21 includes a CPU that executes a program, a RAM, a ROM, and the like that store program instructions or data. The control unit 21 controls each unit according to a program stored in a ROM or a storage unit (not shown).

  The map data storage unit 22 stores data for drawing a map. The drawing data includes terrain drawing data for drawing terrain, road drawing data for drawing roads, road-related information drawing data for drawing detailed information about roads (for example, intersection information, signal information, etc.), etc. including.

  Under the control of the control unit 21, the altitude calculation processing unit 21 executes an altitude calculation process for the object based on the information related to the object transmitted from the mobile terminal 1, and registers the processing result in the database 24.

  The database 24 stores a label ID, a label name, label position information, and altitude information in association with each other.

  The label ID is information that can uniquely identify the label included in the object from the information related to the object transmitted from the mobile terminal 1, and is automatically given by the map distribution server 2. The label name is a label indicating the characteristics of the store included in the information related to the object transmitted from the mobile terminal 1. The position information of the label is registered position information of the object on the map (for example, upper left coordinates and lower right coordinates of the rectangle) included in the information related to the object transmitted from the mobile terminal 1. The registered position information of the object is latitude / longitude information acquired using the GPS function of the mobile terminal 1 or position information designated by the user on the map displayed on the mobile terminal 1. The altitude information is information indicating the altitude of the object (label) calculated by the altitude calculation processing unit 23.

  The communication control unit 25 includes a communication control device, a communication port, and the like, and is a communication interface that mediates communication between the map distribution server 2 and the network 3, and the map distribution server 2 and the mobile terminal 1 are connected via the network 3. Control communication between the two.

  The network 3 is a network such as the Internet or a local area network (LAN), and wired or wireless is not particularly limited.

  Next, the altitude calculation process executed by the map distribution server 2 will be described with reference to the flowchart of FIG.

  This altitude calculation process is performed every time the user registers an object in the mobile terminal 1. That is, when an object is registered in the portable terminal 1, information about the object is transmitted to the map distribution server 2 via the network 3, and stored in the database 24 as label ID, label name, and label position information. . Then, using the flowchart of FIG. 6, altitude information for associating with information (label ID, label name, and label position information) stored in the database 24 is calculated.

  In step S1, the altitude calculation processing unit 23 defines a horizontal margin rate, a screen depth direction margin rate, and a list of input labels as parameters (input variables). In step S2, the altitude calculation processing unit 23 sets initial values in list variables called placed label sets. Is set, and variable i = 1 is set in step S3. The input label list is a list of data stored in the database 24.

  In step S4, the altitude calculation processing unit 23 substitutes the i-th element of the input list into a variable called a label. In step S5-1, the altitude calculation processing unit 23 performs horizontal margin calculation processing.

  Here, the details of the horizontal margin calculation processing in step S5-1 in FIG. 6 will be described with reference to the flowchart in FIG.

  In step S21, the altitude calculation processing unit 23 defines the label and the horizontal margin rate as parameters.

  In step S22-1, the altitude calculation processing unit 23 calculates the horizontal size of the label (object) of interest. For example, as shown in FIG. 8, the horizontal size is obtained by calculating the difference between the lower right coordinate (X coordinate) of the circumscribed rectangle of the object and the upper left coordinate (X coordinate) of the circumscribed rectangle of the object. In step S22-2, the altitude calculation processing unit 23 calculates the vertical size of the label of interest. For example, as shown in FIG. 8, the vertical size is obtained by calculating the difference between the lower right coordinate (Y coordinate) of the circumscribed rectangle of the object and the upper left coordinate (Y coordinate) of the object rectangle.

  In step S23, the altitude calculation processing unit 23 selects the horizontal size of the label obtained as a result of the calculation in step S22-1 and the vertical size of the label obtained as a result of the calculation in step S22-2. A value obtained by multiplying the small size by the value of the horizontal margin rate is assigned to a variable called a horizontal margin.

  In step S24, the altitude calculation processing unit 23 adds the horizontal margin to the left side of the label circumscribing rectangle and adds the horizontal margin to the right side of the label circumscribing rectangle as shown in FIG. Further, as shown in FIG. 8, the altitude calculation processing unit 23 adds the horizontal margin to the upper side of the label circumscribing rectangle and adds the horizontal margin to the lower side of the label circumscribing rectangle. Then, the altitude calculation processing unit 23 returns the circumscribed rectangle of the label with the horizontal margin as a return value.

  Returning to the description of FIG. In step S6, the altitude calculation processing unit 23 performs a superimposed label calculation process.

  Here, the details of the superimposed label calculation process in step S6 of FIG. 6 will be described with reference to the flowchart of FIG.

  In step S31, the advanced calculation processing unit 23 defines a label set that has been placed and a label as parameters, and in step S32, sets an initial value for a list variable called a superimposed label set.

  In step S33, the advanced calculation processing unit 23 determines whether or not the margined circumscribed rectangle of the arranged label and the margined circumscribed rectangle of the label of interest overlap, and the margined circumscribed rectangle of the arranged label, If it is determined that the circumscribed rectangle including the margin of the label of interest overlaps, the process proceeds to step S34.

  In step S34, the altitude calculation processing unit 23 adds the arranged label to the superimposed label set. In step S35, the advanced calculation processing unit 23 determines whether or not all elements included in the arrangement label set have been processed, and if it is determined that there is an element that has not been processed yet, the process proceeds to step S33. Returning to the above-described process repeatedly.

  In step S35, when the altitude calculation processing unit 23 determines that all elements included in the arrangement label set have been processed, the process proceeds to step S36, where the superimposed label set is returned as a return value.

  Returning to the description of FIG. In step S7, the altitude calculation processing unit 23 performs maximum altitude calculation processing.

  Here, with reference to the flowchart of FIG. 10, the detail of the maximum height calculation process of step S7 of FIG. 6 is demonstrated.

  In step S41, the altitude calculation processing unit 23 defines a superimposed label set as a parameter, and in step S42, initializes a variable called maximum altitude.

  In step S43, the altitude calculation processing unit 23 determines whether or not the maximum altitude is less than the superimposed label altitude. If it is determined that the maximum altitude is less than the superimposed label altitude, the process proceeds to step S44, and the value of the superimposed label altitude is set. Substitute into a variable called maximum altitude. On the other hand, if the altitude calculation processing unit 23 determines in step S43 that the maximum altitude <the superimposed label altitude is not satisfied (the maximum altitude ≧ the superimposed label altitude), the process of step S44 is skipped and the process proceeds to step S45.

  In step S45, the altitude calculation processing unit 23 determines whether or not all elements included in the superimposed label have been processed. If it is determined that there is an element that has not yet been processed, the process returns to step S43. The above-described processing is repeatedly executed.

  In step S45, when the altitude calculation processing unit 23 determines that all elements included in the superimposed label have been processed, the altitude calculation processing unit 23 proceeds to step S46 and returns the maximum altitude as a return value.

  Returning to the description of FIG. In step S5-2, the altitude calculation processing unit 23 performs a screen depth direction margin calculation process. The process of step S5-2 is performed in parallel with the process of step S5-1.

  Details of the screen depth direction margin calculation processing in step S5-2 in FIG. 6 will be described with reference to the flowchart in FIG.

  In step S51, the altitude calculation processing unit 23 defines the label and the screen depth direction margin rate as parameters.

  In step S52-1, the altitude calculation processing unit 23 calculates the horizontal size of the target label (object). This process is the same as the process described in step S22-1 in FIG. In step S52-2, the altitude calculation processing unit 23 calculates the vertical size of the label of interest. This process is the same as the process described in step S22-2 in FIG.

  In step S53, the altitude calculation processing unit 23 selects the horizontal size of the label obtained as a result of the calculation in step S52-1, and the vertical size of the label obtained as a result of the calculation in step S52-2. A value obtained by multiplying the small size by the value of the screen depth direction margin rate is substituted into a variable called the screen depth direction margin. This screen depth direction margin is attached only to the back side of the screen with respect to the label (object) as shown in FIG.

  In step S54, the altitude calculation processing unit 23 returns the screen depth direction margin as a return value.

  Returning to the description of FIG. After the maximum altitude calculation process in step S7 and the screen depth direction margin calculation process in step S5-2, the process proceeds to step S8, and the altitude calculation processing unit 23 sets the maximum altitude + screen depth direction margin to a variable called label altitude. substitute.

  In step S9, the altitude calculation processing unit 23 adds the label of interest to the arranged label set. In step S10, the altitude calculation processing unit 23 increments the variable i by 1. In step S11, the altitude calculation processing unit 23 determines whether or not processing has been performed on all elements included in the input label list, and processing is still performed on all elements included in the input label list. If it is determined that the process has not been performed, the process returns to step S4 and the above-described process is repeatedly executed.

  In step S <b> 11, if the altitude calculation processing unit 23 determines that all elements included in the input label list have been processed, the process ends.

  As described above, every time a user registers an object in the mobile terminal 1, the map distribution server 2 can calculate the altitude set for the object. The map distribution server 2 stores the altitude information as the calculation result in the database 24 and transmits the altitude information of the object to the mobile terminal 1 via the network 3. The mobile terminal 1 can display overlapping objects on a map based on the received altitude information.

  Next, display control processing executed by the mobile terminal 1 will be described with reference to the flowchart of FIG. This process is started when display of map data is instructed by the user.

  In step S61, the display control unit 14 of the mobile terminal 1 reads the map data stored in the storage unit 12 and displays it on the screen. At this time, the control unit 11 receives the altitude information of the object registered on the map data from the map distribution server 2 via the network 3 and supplies it to the display control unit 14. The display control unit 14 displays the objects in a predetermined order (object registration order) based on the altitude information of the object from the control unit 11.

  In step S62, the operation reception unit 13 of the mobile terminal 1 determines whether or not a screen scroll operation has been received from the user. If it is determined that the screen scroll operation has been received from the user, the process proceeds to step S63. Screen scrolling is performed using a touch panel or a mouse. On the other hand, if it is determined in step S62 that the screen scroll operation has not been received from the user, the operation reception unit 13 skips the processes in steps S63 and S64 and proceeds to step S65.

  In step S63, the control unit 11 calculates the moving distance of the object based on the screen scroll amount and the altitude information of the object registered on the map data. The calculated moving distance becomes longer when the altitude information is high, and becomes shorter when the altitude information is low.

  In step S64, the display control unit 14 changes the display position of the object based on the movement distance calculated in the process of step S63. In step S65, the operation reception unit 13 determines whether or not a display end operation has been received from the user. If it is determined that the display has not ended yet, the operation reception unit 13 returns to step S61 and repeats the above-described processing.

  In step S65, if the operation reception unit 13 determines that the display is to be ended, the process ends.

[Effects of the embodiment of the invention]
1. As described above, it is possible to display overlapping objects on the map based on the altitude information of the objects. Further, an object buried under the overlap can be displayed by a simple screen scrolling operation.

  2. Further, since the objects are arranged so as to be stacked on the map in the order of registration of the objects, the objects registered recently by the user can be arranged at the top of the overlap. Thereby, it can display in the order of information which a user is more interested.

[Modification]
1. In the above description, the objects are arranged so as to be stacked on the map in the order of registration of the objects. However, the present invention is not limited to this, and it is possible to change the display of the label designated by the user to the top. For example, when the user wants to find a ramen shop, the store can be easily searched by changing the display so that the object having the ramen label is displayed at the top.

  2. Alternatively, the priority order of labels may be set in advance, and the overlap of objects may be updated based on the priority order each time the user registers an object.

  3. The altitude information of the object calculated by the altitude calculation processing unit 23 of the map distribution server 2 is managed by the database 24. However, the present invention is not limited to this, and the mobile terminal 1 receives the information and stores it in the storage unit 12 (management). You may make it do.

  4). Although the altitude calculation processing unit 23 is provided in the map distribution server 2, the present invention is not limited to this, and the map data and the registered position information of the object are stored in the storage unit 12 of the mobile terminal 1, and the altitude calculation processing unit 23 is stored in the mobile terminal. 1, the altitude information of the object may be calculated on the mobile terminal 1 side and stored in association with the information related to the object stored in the storage unit 12. In this case, the map distribution server 2 is not particularly required.

5. In the embodiment of the present invention, an object on map data is targeted, but map data is merely an example. In addition to map data, the present invention can also be applied to design drawing data such as buildings and devices, correlation diagram data indicating relationships between persons and objects, and the like. In the case of design drawing data, each member of a building, each part of an apparatus, and the like are objects. In the case of correlation diagram data, a person or an object is an object.
As described above, the present invention can be widely applied to object arrangement data in which a plurality of objects are arranged and position information of the objects is defined.

  The preferred embodiments of the information display system and the like according to the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention. Understood.
