There is a mechanism to place an icon of an evacuee (pedestrian) in a building on a map and perform an evacuation simulation in which the icon is moved toward an evacuation area assuming that a disaster has occurred.

For example, Patent Document 1 describes tsunami damage prediction data and a simulation technique for evacuating a pedestrian object to an evacuation destination according to the walking speed of each pedestrian.

Japanese Unexamined Patent Publication No. 2007-20803

During an evacuation simulation, you may want to check the route that a pedestrian walked. Therefore, we want to display the movement route on the walking area of pedestrians.

On the other hand, in the evacuation simulation, pedestrians may be moving even though they are not walking. For example, there is a warp area that warps an evacuated pedestrian to another position, and it is used when the pedestrian is moved to a floor and moved to a drawing on another floor.

In the case of a complicated map / blueprint, it is difficult to understand which warp area the pedestrian has moved from to which warp area only by displaying the movement locus on the walking area.

Further, it is desired to display a locus indicating from which warp region the pedestrian has moved to which warp region, but this locus is different from the movement locus in which the pedestrian actually walked and moved. Therefore, for example, a simple diagram with a small warp area may not be displayed.

An object of the present invention is to provide a mechanism that makes it possible to easily display the evacuation position of an evacuee according to the information of the position history.

In the present invention, in order to perform an evacuation simulation of an evacuee, a first determination means for determining the next position of the evacuee according to the information of the evacuee and the evacuee have reached a predetermined point. An information processing apparatus including a second determining means for determining the next position of the evacuee according to the information of the predetermined point, the first determining means and the second determining means. From the position before the next position is determined by the first determination means to the next position determined by the first determination means, which is specified based on the history of the position of the evacuees determined by It is characterized by comprising a control means for controlling the display of the first section, which is the section of the above.

According to the present invention, it is possible to provide a mechanism capable of easily displaying the evacuation position of an evacuee according to the information of the position history.

The information processing apparatus 100 includes CAD software 110 (drawing function unit) and evacuation simulation software 120 (simulation function unit) that functions as a plug-in of CAD software 110.

The information processing device 100 in the present embodiment is a PC, and the CAD software 110 is CAD (Computer-Aided Design) application software installed in the information processing device. Further, the evacuation simulation software 120 is software that functions as a plug-in of CAD application software, performs evacuation simulation using CAD figures (objects), and stores and manages the results.

The evacuation simulation software 120 includes a simulation engine. The evacuation simulation software 120 uses the simulation engine to create a pedestrian icon (walking) placed in a walking area (an object in which the pedestrian icon indicates an area where walking is permitted) on the map created by the CAD software 110. Performs simulation processing to evacuate a person's object) to an evacuation site (evacuation destination) on the map.

More specifically, the evacuation simulation software 120 advances the time on the simulation from the start of the simulation at regular intervals, and performs a simulation process of moving the pedestrian icon toward the evacuation site with the passage of time. ..

The evacuation simulation software 120 can perform evacuation simulation assuming the occurrence of various disasters. For example, the evacuation simulation software 120 can perform an evacuation simulation assuming the occurrence of a water disaster such as a tsunami, a flood, or a flood of a river, a fire, or a landslide disaster. The above is the description of FIG.

Next, an example of the hardware configuration of the information processing apparatus 100 and the like in the embodiment of the present invention will be described with reference to FIG.

The information processing apparatus 100 includes a CPU 201, a ROM 202, a RAM 203, an input controller 205, a video controller 206, a memory controller 207, and a communication I / F controller 208. The CPU 201, ROM 202, RAM 203, input controller 205, video controller 206, memory controller 207, and communication I / F controller 208 are connected to each other via the system bus 204.

The CPU 201 is a central processing unit that collectively controls each device and controller connected via the system bus 204. The ROM 202 is a storage device that stores various programs such as BIOS (Basic Input / Output System), which is a control program of the CPU 201, and various data.

The RAM 203 is a storage device that functions as a main memory, a work area, or the like of the CPU 201. The CPU 201 realizes various operations by loading a program or the like necessary for executing the process from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

The input controller 205 is a controller that controls the input from the input device 209. The input device 209 is an input device such as a pointing device such as a keyboard (KB) or a mouse. The video controller 206 is a controller that controls the display on the display device 210. The display device 210 is a display device such as a CRT display (CRT). The display device 210 may be not only a CRT but also another display such as a liquid crystal display.

The memory controller 207 is a controller that controls access to the external memory 211. The external memory 211 is a storage device such as a hard disk (HD) for storing an operating system program (hereinafter, OS), various setting information, and a flexible disk (FD). Further, the external memory 211 stores a boot program, programs of various applications, font data, user files, editing files, various data, and the like. The memory controller 207 can also control access to an external memory 211 such as a flash memory type memory card connected to the PCMCIA card slot via an adapter.

The communication I / F controller 208 is a controller used for connection / communication with an external device via a network such as a LAN or the Internet, and executes communication processing via the network. The communication I / F controller 208 can communicate with an external device using TCP / IP, for example.

The CPU 201 enables display on the display device 210 by, for example, executing an outline font expansion (rasterization) process in the display information area in the RAM 203. Further, the CPU 201 can receive a user's instruction via a mouse cursor or the like on the display device 210.

It is assumed that the various programs for realizing the processing of the present embodiment are stored in the external memory 211, but they may be stored in the ROM 202. Further, although it is assumed that the definition file and various information tables used when the above program is executed are also stored in the external memory 211, they may be stored in the ROM 202.

The display device 210 is an example of an output unit that displays and outputs an object generated by the CAD software 110 (for example, an object of a new road connecting a building and a road) in response to an instruction from the evacuation simulation software 120. The above is the explanation of FIG.

By executing the process based on the program stored in the ROM 202 or the external memory 211, the CPU 201 realizes the function of the information processing apparatus 100 described later in FIG. 3 and the process of the flowchart of each figure described later.

FIG. 3 is a diagram showing an example of the functional configuration of the information processing apparatus 100. The information processing apparatus 100 includes CAD software 110 (CAD drawing function unit) and evacuation simulation software 120 (evacuation simulation function unit).

The object generation unit 311 generates an object which is a CAD figure in response to a user operation on the CAD software 110 or an instruction from the evacuation simulation software 120.

The object storage management unit 312 is a functional unit that stores and manages the generated objects in an external memory. An example of the object is shown in the object information 400 of FIG.

Each object has the object ID 401 which is the identification information of the object and the information of the vertex coordinates 402 of the object (X and Y coordinates on the CAD file (drawing)). The shape of the vertices connected in order is the shape of the object.

Further, as shown in the attribute 403, an attribute indicating what the object is is stored in association with the attribute. Attributes include, for example, roads, buildings, obstacles, walking areas, pedestrians, walking speed, and the like.

The area indicated by the object to which the attribute of the walking area is given indicates that the area can be walked by a pedestrian (evacuee) in the evacuation simulation. Objects with building attributes (building objects) indicate buildings. An object with a road attribute (road object) indicates a road.

For example, 601 in FIG. 6 is an object indicating one floor of one building, and has an attribute of a walking area. Further, it is assumed that 603 and 606 are objects having the attribute of the stairs, and the attribute of the walking area is given. Reference numeral 606 is an object created to confirm the movement of pedestrians on the stairs between each floor.

An object to which an obstacle attribute is given (obstacle object) indicates an obstacle that defines an area that pedestrians cannot pass through. When the objects in the walking area are in contact with each other or overlap with each other, the pedestrian can freely move between the objects in contact with each other or overlap with each other.

If the obstacle object and the pedestrian icon overlap, the pedestrian icon shall be immovable and fixed at the position where it overlaps with the obstacle object. An example of an obstacle object is a tsunami object whose shape is determined from the data of the inundation area of the tsunami. In addition, rubble that falls due to the collapse of buildings is also an object of obstacles.

Attribute 403 = The pedestrian object is a pedestrian icon. In the present embodiment, it is assumed that the pedestrian icon is already arranged on the drawing (initial position is registered) as shown in 602 of FIG.

The drawing referred to here is a CAD file that can be expanded by the CAD software 110, and is a file in which a figure (object) is arranged. The evacuation simulation software 120 executes an evacuation simulation using, for example, a drawing developed by the CAD software 110.

The center position of the pedestrian icon can be specified from the coordinates of the pedestrian icon. The central position is the initial position of the pedestrian icon before evacuation.

The speed (m / sec) of the pedestrian icon is the moving speed at which each pedestrian icon moves toward the destination in the evacuation simulation.

The object having the warp ID in the attribute 403 is an object indicating the warp area (warp area itself). In the present embodiment, it is assumed that two objects having the same warp ID are created for each warp ID, and the objects having the same warp ID are created and stored as objects having the same shape.

The evacuation simulation software 120 warps another warp area having the same warp ID as the warp area when the pedestrian icon overlaps the object in one warp area, that is, when the pedestrian reaches the warp area. Specify as the previous warp area. Then, the same position in the warp area of the warp destination as the position in the warp area reached by the pedestrian icon is determined as the next position (warp destination position) of the pedestrian icon. An example of an object in the warp area is shown in FIGS. 604, 607, and the like.

It is also assumed that the evacuation destination is already generated and arranged on the drawing as an object having the attribute of the evacuation destination. An example of the destination object is shown in FIGS. 605, 608, 609 and the like.

Further, the attribute 403 includes a color setting and a transparency setting of each object. The above is the description of the object information 400.

Returning to the description of FIG. The object display setting unit 313 stores, updates, and changes the settings related to the display of the object. For example, some or all of the objects instructed by the evacuation simulation software may be hidden or the color settings may be changed.

The object display unit 314 arranges and outputs objects on the drawing according to the color and transparency set by the object display setting unit 313, and displays them on the display screen.

The simulation execution unit 321 is a processing unit that performs a simulation of evacuating a pedestrian icon for an evacuation purpose. For example, the position of the next destination of the pedestrian is determined from the position and speed of the pedestrian itself at predetermined time intervals (for example, every 0.1 seconds from the start of the simulation), and the simulation is performed.

The simulation is performed from the start of the simulation to a predetermined time. It is assumed that the information at the predetermined time is stored in the external memory in advance.

When a pedestrian enters the warp area, the other warp area paired with the warp area is specified, and a predetermined position on the other warp area is set as the next destination of the pedestrian icon. Determine the position of. Then, the history of the positions of these pedestrians is output as a simulation result.

The position history storage unit 322 stores the pedestrian position history information output from the simulation execution unit 321 from the start to the end of the simulation. An example of the position history information is shown in the route data 410 of FIG.

The route data 410 is newly generated every time the evacuation simulation is executed and stored in the external memory.

The date and time 411 indicate the recording date and time of the data. Time 412 is the elapsed time from the start of the simulation. The position 414 is the position (X, Y coordinates on the drawing) of the pedestrian icon of the icon ID 413 at the date and time 411 and the time 412.

The normal section specifying unit 323 specifies, for example, a walking section in which the pedestrian icon has moved according to the attribute information of the pedestrian icon itself. When the pedestrian icon moves to the position of another warp area due to, for example, the pedestrian icon entering the warp area, the warp section specifying unit 324 specifies the section at the position before and after the movement as the warp section.

Specifically, when the distance between two consecutive positions of one pedestrian is a predetermined distance (eg, 1.5 m) or more, the section between these two positions is specified as a warp section. .. If the distance is less than 1.5 m, the section between these two positions is specified as a normal section.

Here, a distance of 1.5 m is given as an example of a predetermined distance. Drawings with different floors are often drawn at regular distance intervals (for example, at distance intervals of 1.5 m or more), so when the straight line distance of one section is 1.5 m or more, the floors are used between the warp areas. This is because it is considered to be moving. Further, from the setting of the movement speed of the pedestrian in the evacuation simulation of the present embodiment, it is unlikely that the pedestrian icon walks 1.5 m in 0.1 seconds, so 1.5 m is set as a reference value. is doing.

The value of the predetermined distance can be arbitrarily set / changed on the setting screen (not shown) of the evacuation simulation software 120, and the set value / changed value is stored in the external memory 211.

The object display control unit 325 is a control unit that instructs the CAD software 110 to create and display an object in a normal section and an object in a warp section, and controls the display of the object.

For example, the CAD software is instructed to display only the normal section, or the object in the normal section and the object in the warp section are instructed to be distinguished and displayed. The above is the explanation of FIG.

Next, with reference to FIG. 5, the flow of simulation execution in the embodiment of the present invention will be described.

In step S501, the CAD software 110 is activated in response to an operation by the user via the input device 209.

Further, the CAD software 110 reads drawing data from the external memory 211 or the like in response to an operation by the user via the input device 209, expands the read drawing data information on the RAM 203, and stores it. For example, it is assumed that drawing data, which is a set of objects as shown in the object information 400, is read.

Then, the CAD software 110 displays an object (a drawing including the object) corresponding to the drawing data stored in the RAM 203 in the display screen of the CAD software 110 displayed on the display device 210.

For example, as shown in 600 of FIG. 6, the drawing is displayed on the window displayed by the CAD software. In 600 of FIG. 6, the CAD software 110 reads out the information of the drawing (for example, the object information 400) into the RAM 203 and arranges it on the screen of the CAD software 110 displayed on the display device 210 according to the value of the vertex coordinates 402. is doing.

In step S502, the CAD software 110 activates the evacuation simulation software 120 in response to a user operation via the input device 209. If the evacuation simulation software 120 has already been started, the CAD software 110 responds to the user's operation via the input device 209 with respect to the started evacuation simulation software 120 on the setting screen of the evacuation simulation software 120. Instruct the display.

In step S503, the evacuation simulation software 120 is activated by the start instruction from the CAD software 110 in step S503, and the setting screen of the evacuation simulation software 120 is displayed on the display screen displayed by the CAD software 110.

Specifically, when "evacuation simulation" is selected in the button list 610 displayed by the CAD software 110 by accepting the pressing of the tool tab of the CAD software 110, the CAD software 110 instructs the evacuation simulation software 120 to start. Is issued. Then, the evacuation simulation software 120 that has received the activation instruction displays the setting screen 620 (shown in FIG. 6) in step S503.

In step S504, the evacuation simulation software 120 receives an evacuation simulation execution instruction (start instruction) based on the user's operation via the screen displayed on the display device 210 or the input device 209.

For example, the evacuation simulation software 120 accepts an evacuation simulation execution instruction by accepting the selection of the "execute" button on the setting screen 620 based on the user's operation via the input device 209.

In step S505, the evacuation simulation software 120 acquires information on the pedestrian icon arranged on the drawing opened by the CAD software 110. For example, the CAD software 110 is requested to list the icon IDs of the pedestrian icons included in the drawing (object information 400) being developed.

The CAD software 110 that has received the request acquires the ID list of the pedestrian icon in the drawing being developed from the memory and transmits it to the evacuation simulation software 120, and the evacuation simulation software 120 receives and acquires the ID list.

In step S505, the evacuation simulation software 120 applies the processes of steps S506 to S512 to all unfixed (not overlapping with obstacles) pedestrian icons every 0.1 seconds.

In step S506, the evacuation simulation software 120 acquires one pedestrian icon to which the process has not been applied. Then, it is determined whether or not the pedestrian icon overlaps with an obstacle object (for example, a tsunami object).

Specifically, using the API of the CAD software 110, a list of obstacle objects is requested from the CAD software 110 and acquired, and within the frame of the obstacle object specified from the apex coordinates 402 of the obstacle object, When the apex coordinates 402 of the pedestrian icon being processed overlap, it is determined that the pedestrian icon overlaps with the obstacle object.

If it is determined that the pedestrian icon being processed overlaps with the obstacle object, the pedestrian icon that overlaps with the obstacle object is identified as a pedestrian (evacuee) who has delayed escape (failed to evacuate). Then, the position of the pedestrian icon is fixed until the simulation is completed (step S512).

Specifically, until the simulation is completed, the position of the pedestrian icon at the time when the pedestrian icon overlaps the obstacle object is recorded at the position 414 of the pedestrian icon at each time 412 in the route data 410. Continue to do. That is, the position is continuously memorized until the end of the simulation.

If it is determined in step 507 that the pedestrian icon does not overlap with the obstacle object, the process proceeds to step S508.

In step S508, the evacuation simulation software determines whether the pedestrian icon being processed is located in the warp area. Specifically, using the API of the CAD software 110, a list of objects having a warp ID in the attribute 403 (objects in the warp area) is requested from the CAD software 110 and acquired.

Then, when the vertex coordinates 402 of the pedestrian icon being processed overlap within the frame of the object in the warp area (inside the warp area) specified from the vertex coordinates 402 of the object in the warp area, the pedestrian icon is in the warp area. Judged to be located inside.

When the evacuation simulation software 120 determines that the pedestrian icon being processed is located in the warp area, the evacuation simulation software 120 shifts the processing to step S509. If it is determined that the pedestrian icon being processed is located outside the warp area, the process proceeds to step S510.

Even if it is determined that the current position of the pedestrian is in the warp area, if the position immediately before it is in the same warp area, for example, the warp is made after already warping from another warp area. It is determined that the pedestrian is walking to get out of the area, and the process is shifted to step S510. As a result, it is possible to omit the useless process of warping to the other warp area each time the pedestrian enters the warp area and then moves to the next position. Therefore, even when creating an object for a movement route, which will be described later, it is possible to create and present an object with a clear movement trajectory without creating and displaying a useless movement trajectory that reciprocates in the same warp area.

In step S509, the evacuation simulation software 120 identifies an object in the warp area where the pedestrian icon is located, and identifies another object having the same warp ID as the object in the warp area as an object in the warp area of the warp destination. ..

The objects in the warp area having the same warp ID are paired (paired) areas that are the source and destination of the pedestrian icon. It is assumed that the objects in the paired warp area have the same shape.

In step S511, the evacuation simulation software 120 determines the position in the warp area of the warp destination, which is the same as the position in the warp area where the pedestrian icon is located, as the position of the next movement destination of the pedestrian icon, and RAM. The position (X, Y) on the drawing of the moving destination is stored above.

Specifically, when the route data 410 for the evacuation simulation currently being executed is not generated on the RAM, a new route data 410 for the evacuation simulation is newly generated on the RAM, and 0 seconds after the start. Insert the initial position of the pedestrian icon in the data. Then, a record of the pedestrian icon being processed is added to the data at the next time (example: 0.1 seconds later) of the route data 410, and the position in the warp area of the warp destination is inserted into the position 414. Remember. If the route data 410 for the evacuation simulation already exists in the RAM, the process of adding the record to the route data 410 and storing the position is performed. According to the drawing of FIG. 6, since the warp area is created larger than the destination, the pedestrian icon moving toward the destination is the warp area before reaching the destination on each floor. Will enter and warp to another warp area at the warp destination.

On the other hand, in step S510, the evacuation simulation software 120 acquires information on the moving speed of the pedestrian icon being processed, and calculates the position of the pedestrian after a predetermined time.

For example, the passing point to be passed to the evacuation destination is calculated, a straight line calculated from the current position of the pedestrian icon to the passing point is virtually created, and the speed of the pedestrian icon (eg: 1 m / sec). ), The position X at the next time (after a predetermined time / eg, after 0.1 seconds) when the vehicle is moved toward the passing point on the straight line is calculated as the position of the pedestrian.

In step S511, the evacuation simulation software 120 determines the calculated next position as the next position of the pedestrian icon and stores it in the memory. For example, a record of the pedestrian icon is added to the data of the time 412 next to the route data 410 on the RAM, and the position X, which is the next position, is stored in the position 414.

The method of calculating the next position of a pedestrian is not limited to this. The calculation method of the next position differs depending on the calculation method of the simulation engine. However, in the present embodiment, the next position of the pedestrian when the process is shifted from step S510 to S511 shall be calculated and determined based on the movement speed of the pedestrian himself acquired in step S510.

The processes of steps S506 to S512 for each pedestrian icon are processed in parallel as much as possible. The evacuation simulation software 120 applies the processes from steps S506 to S512 to all the pedestrian icons, and shifts the processes to step S513.

In step S513, the evacuation simulation software 120 determines whether the simulation end condition is satisfied. The simulation end condition is, for example, a condition such as whether or not a predetermined time (here, 300 seconds in the simulation) has elapsed after the start of the simulation.

In the present embodiment, it is determined that the simulation end condition is satisfied when 300 seconds have elapsed from the start of the simulation.

The simulation end condition is not limited to time. For example, it may be determined that the end condition is satisfied when all the pedestrian icons reach the evacuation destination and the end condition is satisfied when all the pedestrian icons reach the evacuation destination.

If the end condition is not satisfied, the process proceeds before step S505, and the process of moving the pedestrian icon (process of evacuation simulation) is continued. When the end condition is satisfied, the process shown in FIG. 5 is terminated and the evacuation simulation is completed. Then, the evacuation simulation software 120 stores the route data 410 stored in the RAM in the external memory 211 in association with the ID newly assigned for each evacuation simulation. The above is the explanation of FIG.

Next, with reference to FIG. 7, the flow of the root object creation process in the embodiment of the present invention will be described.

The route object is an object that shows the movement trajectory of a pedestrian, and is an object that shows the history of the position of each pedestrian in the evacuation simulation.

In step S701, the CAD software 110 accepts a user operation. For example, the screen 600 shown in FIG. 9 accepts a user operation. The 600 in FIG. 9 is the same screen as the screen 600 in FIG.

In step S702, the CAD software 110 determines whether the received user operation is a command execution operation for plotting the movement locus.

Specifically, when the operation of selecting the button of the walking locus plot command is accepted from the menu of the CAD software 110 shown in 610 of FIG. 9, it is determined that the command execution operation of the plot of the moving locus is performed.

There are other operations that the CAD software 110 can accept. For example, an object selection operation. For example, by accepting a mouse click operation while the mouse cursor is placed on the object, the CAD software 110 accepts the operation of selecting / deselecting the object, and determines / stores the selected state of the object according to the operation.

For example, by accepting an operation of moving the mouse cursor to an arbitrary pedestrian icon and clicking it, the selection of the clicked pedestrian is accepted and the pedestrian icon is set to the selected state. The selected pedestrian icon is stored in a list of selected objects (not shown) stored in the memory, and the selected pedestrian object is managed.

In step S703, the CAD software 110 gives a command execution instruction to the evacuation simulation software 120. In step S704, the evacuation simulation software 120 receives a command execution instruction.

In step S705, the evacuation simulation software 120 receives the command execution instruction and displays a selection screen for a route creation target (not shown). On the selection screen, the route data stored at the completion of the simulation of FIG. 5 is displayed in a list in parallel with the ID of the evacuation simulation. The evacuation simulation software 120 accepts a user operation of selecting the route data of the target for which the route object is created on the selection screen from the route data displayed in the list.

Then, the selected route data is read out on the RAM, and the selected route data is used to execute the subsequent process of creating a route object related to the past position of the pedestrian icon. In the description of this figure, it is assumed that the root data 410 is selected, read out on the RAM, and stored.

After accepting the selection of the route data 410, the evacuation simulation software 120 displays a dialog as shown in 900 in FIG. 9 on the display screen.

In step S706, the evacuation simulation software 120 accepts the user operation on the dialog 900.

In step S707, it is determined whether the operation received in step S706 is an execution operation for creating a root object. Specifically, when the operation of selecting the "OK" button 901 in the dialog is accepted, it is determined that the execution operation of creating the root object has been performed.

If it is determined that the execution operation for creating the root object has been performed, the process proceeds to step S708. If the operation received in step S706 is not an execution operation for creating a root object, for example, if it is a selection operation of the "Cancel" button, the process ends.

When it is determined in step S707 that the execution operation for creating the route object has been performed, the evacuation simulation software 120 performs determination processing and storage processing for the pedestrian to be created for the route object.

For example, in the evacuation simulation software 120, the operation received in step S706 is an operation in which only the pedestrian (pedestrian icon) selected on the drawing of the CAD software 110 is targeted for creating a route object, or all pedestrians are selected. Determine if it is the target operation.

Specifically, when the "OK" button 901 is pressed, the check state of the "draw only selected person" check box 902 in the dialog 900 is confirmed. The evacuation simulation software 120 accepts a click operation of the check box 902 to perform a check / uncheck process.

The evacuation simulation software 120 creates a route object only for the selected pedestrian when the operation of pressing the "OK" button 901 is accepted while the check box 902 of "Draw only selected person" is checked. It is determined that the operation to create and execute the target object has been performed.

When the operation for processing only the selected pedestrian is performed, the evacuation simulation software 120 asks the CAD software 110 whether there is a selected pedestrian. Specifically, the CAD software 110 is requested to search for the pedestrian selected on the CAD software 110, and the information on the presence or absence of the selected pedestrian is acquired from the CAD software 110.

When there is a selected pedestrian icon, the CAD software transmits a list of object IDs of the selected pedestrian icon to the evacuation simulation software 120 as information on the selected pedestrian. If there is no selected pedestrian icon, an empty object ID list is transmitted to the evacuation simulation software 120 as information without the selected pedestrian.

The evacuation simulation software 120 refers to the information on the presence or absence of pedestrians acquired from the CAD software 110, and determines whether or not there is a pedestrian icon being selected. If there is a selected pedestrian icon, the object ID list of the selected pedestrian icon is stored in the RAM as a list of pedestrians to be processed.

If there is no selected pedestrian icon, all pedestrians will be processed. Specifically, the object ID list of all pedestrian icons included in the route data 410 is read out and stored in the RAM as a list of pedestrians to be processed.

In addition, when the operation of pressing the "OK" button 901 is accepted when the check box 902 of "Draw only selected person" is not checked, the object creation execution that targets all pedestrians as the root object is executed. It is determined that the operation has been performed. The term "all pedestrians" as used herein means all pedestrian icons included in the route data 410.

When an operation targeting all pedestrians is performed, the evacuation simulation software 120 reads and stores the object ID list of all the pedestrian icons in the RAM as a list of pedestrians to be processed.

In step S708, the evacuation simulation software 120 identifies the route data 410 on the RAM selected by the user. That is, the route data of all times is acquired.

The evacuation simulation software 120 repeats the following processing for all pedestrian icons included in the route data 410.

In step S709, the evacuation simulation software 120 acquires one object ID of the pedestrian icon to which the process of step S711 has not been applied (unprocessed) from the route data 410. If there is no unprocessed pedestrian icon, the process proceeds to step S716.

In step S710, the evacuation simulation software 120 determines whether the acquired pedestrian object ID is the ID of the pedestrian icon to be created and processed for the route object.

The ID list of the pedestrian whose route object is to be created is determined and stored in the above-mentioned determination process and storage process of the pedestrian whose route object is to be created. The evacuation simulation software 120 is said to be included in the case where the pedestrian object ID acquired in step S709 is included in any of the object IDs in the pedestrian ID list to be processed. It is determined that the pedestrian icon is the pedestrian to be processed.

If it is determined that the pedestrian is the processing target, the processing is shifted to step S711, and if it is determined that the processing target is not the pedestrian, the processing of steps S710 to S715 for the pedestrian is skipped and the processing is performed. Return to step S709.

In the following description of FIG. 7, only the pedestrian selected on the CAD software 110 is selected as the root object creation target and is stored in the RAM.

If the object ID of the pedestrian icon acquired in step S709 is the ID of the pedestrian to be processed for creating the route object, the evacuation simulation software 120 shifts the processing to step S711. Here, the process proceeds to step S711 when the object ID of the pedestrian icon selected on the CAD software 110 is used.

In step S711, the evacuation simulation software 120 determines whether or not the acquired pedestrian icon object group exists, and if not, instructs the CAD software 110 to create an object group for the pedestrian's movement route. do.

The group of pedestrian objects is a data format shown in FIG. 830, for example, in which all the objects created from the route data 410 of a pedestrian are collectively managed for each pedestrian. In other words, it is a group related to the movement route of pedestrians.

In the group of objects, for example, the evacuation simulation software 120 moves the pedestrian icon based on the attributes set in the pedestrian icon itself and additional information (speed stored in the attribute 403 in FIG. 4, etc.). It is a group of route objects showing sections and route objects of sections where evacuation simulation software has moved pedestrian icons based on other factors that do not depend on the attributes of pedestrian icons or additional information.

The other factor referred to here is, for example, that the pedestrian icon has reached the warp area. When the pedestrian icon reaches a certain warp area and moves to another warp area, the section between the two warp areas is called a warp section.

The warp area is an area on the drawing particularly required when performing an evacuation simulation on a two-dimensional drawing, and is used as a pair of a warp source area and a warp destination area. In the case of a two-dimensional drawing, for example, the drawings of the rooms on the first floor and the room on the second floor are drawn and created separately.

To move the pedestrian icon from the 1st floor to the 2nd floor and from the 2nd floor to the 1st floor, for example, set a warp area on the object of the stairs in the drawing of each floor, and set the pedestrian icon that has reached the warp area to the other. Need to move to the drawing of the floor where the warp area is located.

This is an example of the case where the evacuation simulation software moves the pedestrian icon based on other factors that do not depend on the attributes of the pedestrian icon or additional information.

Also, especially in drawings with many floors and many stairs, the pedestrian icon is which warp to make it easier to understand which warp area on which stairs the pedestrian has moved to. It is possible to clarify which warp area was moved (position changed / updated) from the area by displaying it as a root object.

In addition, by grouping the objects of these movement routes into one group, a plurality of objects created from the movement history of one pedestrian can be collectively selected and operated for each pedestrian on the CAD software 110. Will be able to.

An example of a group is shown in group information 830 (FIG. 8). The group ID 831 is an identification ID of a group of travel routes for each pedestrian. The evacuation simulation software 120 inserts the object ID of the pedestrian icon of the route object belonging to the group into the group ID 831, and instructs the CAD software 110 to create and store the group.
That is, the group ID 831 is an ID indicating which pedestrian group the object of each object ID 832 belongs to.

1732 is an ID of an object created from the route data of the corresponding pedestrian. As shown in FIG. 8, the group information 830 is created for each pedestrian and stored in the external memory.

Reference numeral 833 is a set of coordinates of one section of the vertices constituting the object. In the case of a route object, the coordinates of two vertices of a line object (or polygonal object) indicating the movement trajectory of the pedestrian, which is specified from the history of the position of the pedestrian, are inserted.

834 is an attribute of one vertex section of the object. In the case of a root object, for example, the RGB value and transparency of the color of the object are inserted in 834.

In step S719, the CAD software 110 receives an instruction to create a group of pedestrian movement routes.

In step S720, the CAD software 110 creates a group of pedestrian travel routes. For example, when the group creation instruction of the pedestrian icon of the object ID = U00001 is received, the group of the movement route of the pedestrian U00001 in 830 of FIG. 8 is newly created, and the value of U00001 is inserted into 831. At this point, the data from 832 to 834 are empty.

The evacuation simulation software 120 acquires all route data 410 of pedestrians determined to be processed in step S710. Then, the processes from steps S712 to S715 are executed for all route data 410 of the pedestrian.

In step S712, the evacuation simulation software 120 identifies and acquires a route for one section of a pedestrian. A route in one section is a set of two positions in which the recording time (time 412 or date and time 411) of one pedestrian is continuous.

For example, it is a set of positions where the elapsed time of U00001 in FIG. 4 is 0 seconds and 0.1 seconds.

In step S713, the evacuation simulation software 120 determines whether the route of one section acquired in step S712 is a warp section.

Specifically, it is determined whether the straight line distance of the one section is equal to or more than a predetermined distance. For example, when the distance is 1.5 m or more, it is determined that the route of one section acquired in step S712 is the route between the warp regions. If it is less than 1.5 m, it is determined to be a normal section (a pair of positions indicating that the pedestrian icon is walking and moving based on its own attribute).

This is, for example, the distance on the two-dimensional drawing of CAD displayed in 600 in FIG. Drawings with different floors are often drawn at regular distance intervals (for example, at distance intervals of 1.5 m or more). Therefore, in the present embodiment, when the linear distance of one section is 1.5 m or more, the section is concerned. Is determined to be a warp section, but the predetermined distance is not limited to 1.5 m.

For example, it is possible to set / change to an arbitrary distance by accepting a user operation on a predetermined distance setting screen (not shown) provided by the evacuation simulation software 120. It is assumed that the value of the predetermined distance is stored in the external memory 211.

If one section acquired in step S712 is not a warp section but a normal section, the process shifts to step S714. If the route of one section acquired in step S712 is a warp section, the process shifts to step S715.

In step S714, the evacuation simulation software 120 stores the route data (position pair) of one section acquired in step S712 in the RAM as the route of the normal section. For example, a new number 811 is assigned to 812 in the normal section 810 of FIG. 8 and stored.

In step S715, the evacuation simulation software 120 stores in the RAM the route of one section acquired in step S712 as the route of the warp section. For example, a new number 821 is assigned to 822 in the warp section 820 of FIG. 8 and stored.

The evacuation simulation software 120 applies the processing up to step S714 or S715 to all the route data of the pedestrian icon determined to be the pedestrian to be processed in step S710, and then shifts the processing to step S716.

In step S716, the evacuation simulation software 120 passes the position information of the normal section 810 and the warp section 820 stored in the RAM in step S714 to the CAD software 110, and connects the position data as vertices in chronological order. Instruct to draw a figure (polygon object).

In addition, the color of the polygonal figure is instructed to be gray 1. Further, the first class on the CAD software of the polygon is set as the object ID of the pedestrian icon being processed (for example, "U00001"), and the second class is instructed to be set as the "normal section".

At the same time, the information on the position of the warp section 820 stored in the RAM in step S715 is passed to the CAD software 110, and the vertices at the position of the warp section among the vertices of the polygon are made transparent (transparency is set to 100%). Instruct to do.

A class is one of units on which a plurality of objects can be collectively selected and displayed and displayed on the CAD software 110. For example, when an operation of selecting an object of the "normal section" class is accepted on the CAD software 110, the CAD software 110 receives all "normal sections" managed by itself regardless of which pedestrian group of objects it has. You can select objects of the class of "" at once.

In step S717, the evacuation simulation software 120 passes the position information of the warp section 820 stored in the RAM in step S715 to the CAD software 110, and draws a line segment (line segment object) having the position data as the apex for each section. Instruct to do.

In addition, the color of the line segment is instructed to be gray 2. Further, the first class on the CAD software of the line segment is set as the object ID of the pedestrian icon being processed (for example, "U00001"), and the second class is instructed to be set as the "warp section".

In step S721, the CAD software 110 receives an object creation instruction. Then, in step S722, the polygon of the normal section is created according to the instruction for creating the object of the received normal section. Then, in the polygon of the normal section, the space between the vertices of the warp section is made transparent and displayed on the display screen. In addition, a line segment of the warp section is created and displayed according to the instruction for creating the object of the received warp section.

Specifically, a new object as shown in the object information 420 of FIG. 4 is added to the object information 400 to update the display.

In step S718, the evacuation simulation software 120 instructs the CAD software 110 to register the object created in steps S716 and S717 in the group of pedestrian icons being processed acquired in step S709. The instruction includes the object ID of the pedestrian icon.

In step S723, the CAD software 110 accepts the instruction. In step S724, the CAD software 110 adds and stores the polygon and line segment objects created in step S722 to the group of pedestrians as shown in 830 of FIG. That is, the process of grouping the objects for each pedestrian is performed. The above is the explanation of FIG.

FIG. 10 shows an example of a screen in which a route object of a warp section and a normal section is created and displayed. 1001 and 1002 are root objects of the normal section. 1003 and 1004 are root objects of the warp section.

As shown in 1010 of FIG. 10, the CAD software 110 accepts a click operation of the root object in the warp section of 1003, so that the first class of the selected object (the class that takes precedence over the second class). Batch select objects of the same class as.

That is, it is possible to collectively select an object related to the position history, for example, a route object for each pedestrian.

The priority of the class can be changed and set in any order on the class order change screen (not shown) of the CAD software 110.

In addition to grouping as an object of one pedestrian, it is also possible to collectively select objects for each of the normal section and the warp section by assigning different classes to the normal section and the warp section.

That is, the evacuation simulation software 120 makes it possible to separately select the route object of the normal section and the route object of the warp section by instructing the CAD software to generate separate route objects for the normal section and the warp section. I am in control. In addition, control is performed so that display / non-display can be switched at once.

For example, as shown in FIG. 11, the CAD software 110 displays the class display setting screen as shown in 1101 and 1111 according to the user operation.

Then, as shown in 1200 of FIG. 12, by accepting the right-click operation of the mouse on the display of the normal section, the "selection" button shown in 1201 is displayed, and the pressing of the "selection" button 1201 is accepted. , Select only objects of class in normal interval. The selection frame is shown in 1202.

Further, as shown in 1210 of FIG. 12, by accepting the right-click operation of the mouse on the display of the warp section, the "selection" button shown in 1211 is displayed, and the pressing of the "selection" button 1211 is accepted. , Select only objects of class in the warp interval. The selection frame is shown in 1212.

In addition to grouping as a single pedestrian object, by assigning different classes to the normal section and the warp section, it is possible to switch between display and non-display for each normal section and warp section at once. Become.

For example, as shown in FIG. 11, the CAD software 110 accepts a click operation on the display / non-display switching check box corresponding to each class on the class display setting screen as shown in 1101 and 1111 to turn the check ON / The OFF state is switched, and only the objects of the checked class are displayed on the drawing.

1100 in FIG. 11 shows an example of a state in which only the root object of the normal section is displayed. 1110 shows an example of a state in which only the root object of the warp section is displayed.

That is, the evacuation simulation software 120 makes it possible to separately select the route object of the normal section and the route object of the warp section by instructing the CAD software to generate separate route objects for the normal section and the warp section. I am in control.

Also, by instructing the root object of the normal section and the root object of the warp section to have different colors, different colors can be set for the root object of the normal section and the root object of the warp section, and the route of the normal section. Control is performed to display the object and the root object of the warp section in an identifiable manner.

Also, by making the line of the warp section transparent among the polygonal root objects of the normal section, the object of the warp section and the object of the normal section do not appear to overlap, so the user can see which section is the warp section. It has the effect of making it easier to recognize.

As described above, according to the first embodiment of the present invention, it is possible to provide a mechanism capable of easily displaying the evacuation position of an evacuee according to the information of the position history.

For example, the normal section and the warp section can be selected separately, and information on the evacuation position of the evacuees can be generated.

In addition, the display of the normal section and the warp section can be switched at once, and it can be used as information on the position where the difficult person is evacuated.

In addition, the normal section and the warp section can be displayed so as to be recognizable.

<Second embodiment>
Evacuation simulation is generally performed for multiple pedestrians at once. Therefore, pedestrians may become clogged depending on the location of evacuation. If the pedestrian is clogged, the pedestrian who came later cannot move forward, so the evacuation simulation software 120 stops the pedestrian icon that came later on the spot.

In addition, when a plurality of pedestrians change their angles and move, and the icon of a pedestrian who comes later comes into contact with the icon of another pedestrian, for example, the pedestrian icons do not overlap with each other. The position of the pedestrian icon that came later may be retracted (pushed back).

When the process of retracting the pedestrian icon is performed near the warp area, for example, as shown in 1310 of FIG. 13, after the pedestrian icon 1313 moves to the warp area from 1311 to 1312 and exits from the warp area 1312, As shown in 1320, the pedestrian icon may return to the warp area 1312.

Then, the evacuation simulation software 120 determines that a pedestrian has newly entered the warp area, and moves the pedestrian icon 1313 to the warp area 1311. That is, pedestrians make a round trip in the same warp area.

Further, in order to move the pedestrian icon 1313 to the warp area 1312 again, it is necessary to once move the pedestrian icon out of the warp area 1311 and re-enter the warp area 1311. It is unlikely that it will move like this, and the accuracy of the evacuation simulation will decrease (by taking a pedestrian out of the warp area and re-entering it). Therefore, it is conceivable that a pedestrian who has stayed in the same warp area for a certain period of time (for example, 1 second) or more will be warped again to the other warp area that is paired with the warp area. The longer you stay, the more round trips between the warp areas. As a result, when a route object is created according to the simulation result, an unnecessarily large number of route objects indicating reciprocating movement between warp regions are generated and displayed as shown in 1301 of FIG. Since the route object between the warp areas is for confirming which warp area the pedestrian icon is moving from to which warp area, one for each pair of warp areas is sufficient.

In the second embodiment, it is an object to provide a mechanism for appropriately displaying the root object of the warp section.

The processing, data, and screen description common to the first embodiment will be omitted.

When the evacuation simulation software 120 determines in step S713 of FIG. 7 that the section acquired in step S712 is a warp section, the evacuation simulation software 120 requests CAD to acquire an object list of the warp area and stores it in the RAM. Then, it is determined by referring to the warp section 820 whether or not there is a warp section that spans the same warp area as the two warp areas where the coordinates of both ends of the warp section are located within the past predetermined time (for example, within 1 second). ..

If there is a warp section that spans the same warp area, that is, a section that indicates that the section acquired in step S712 is moving again between two warp areas that have been warped in the past and the same warp area (warp). In the case of the return route or the second outward route in the round trip between the regions, the information of the section acquired in step S712 is discarded without being stored in the warp section 820, and the process shifts to step S712.

This process can reduce the possibility of creating multiple root objects by going back and forth between the same warp areas.

Therefore, it is possible to provide a mechanism that enables the root object of the warp section to be appropriately displayed, for example, as shown in 1000 of FIG. 10, without creating and displaying a complicated object as shown in 1300.

<Third embodiment>
Evacuation simulation is generally performed for multiple pedestrians at once. Therefore, although it is possible to move at a normal walking speed depending on the place, the walking speed may decrease in a place where pedestrians are clogged.

Possible causes of pedestrian clogging include narrow roads, door size / design, and moving conductors. The user of the evacuation simulation software may check the result of the evacuation simulation and consider the design of the building or the road so as to improve these factors such as the narrowness of the road.

In the third embodiment, it is an object of the present invention to provide a mechanism capable of easily displaying the evacuation position of an evacuee according to the speed information specified from the position history.

Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 14 and 15. The description of the processes, data, and screens common to the first embodiment and the second embodiment will be omitted.

The evacuation simulation software 120 executes the process of FIG. 14 instead of the step S716 of FIG.

In step S1401, the evacuation simulation software 120 acquires the unprocessed head data (data having the earliest elapsed time from the start of the simulation) in the normal section 810.

In step S1402, the evacuation simulation software 120 specifies the speed of a pedestrian who has moved the length of the acquired section. For example, the speed of a pedestrian when moving in the section within 0.1 seconds is specified. Then, it is determined whether the speed of the pedestrian in the section is equal to or higher than the predetermined speed. The predetermined speed is assumed to be the normal movement speed of the pedestrian. When the speed of the pedestrian in the section is equal to or higher than the predetermined speed, the process proceeds to step S1403.

The section data indicates the positions of the movement source and the movement destination per unit time (for example, per 0.1 second). That is, the determination of whether or not the moving speed of the pedestrian in the section is higher than the normal moving speed of the pedestrian is the distance that the pedestrian moves when the distance in the section moves at the normal moving speed. It is a judgment of the above. If the distance is shorter than the distance traveled when the pedestrian travels at a normal travel speed, it means that the pedestrian has traveled the section at a speed slower than the normal travel speed.

In step S1403, the evacuation simulation software 120 determines the data of the section as the data of the section in which the pedestrian has moved at a speed higher than the normal moving speed (first speed) and stores it in the RAM. For example, it is stored in the section information list of the first speed group (not shown).

When the speed of the pedestrian in the section is lower than the normal movement speed of the pedestrian (first speed), the data of the section is obtained at a speed slower than the normal movement speed of the pedestrian (second speed). It is determined as the data of the section moved by (speed of) and stored in the RAM. For example, it is stored in the section information list of the second speed group (not shown) (step S1404).

In step S1405, the evacuation simulation software 120 passes the position information of the first speed section, the position information of the second speed section, and the position information of the warp section 820 to the CAD software 110 in chronological order. Instruct to draw one polygonal figure (polygonal object) connected with the position data as vertices in order.

Also, set the color to gray 3, set the pedestrian ID in the first class, set the "normal section" in the second class, and set the "first speed" in the third class. Instruct.

In addition, among the line segments in the polygon, an instruction is given to set the transparency of the line segments of the second section and the warp section to 100%.

The CAD software 110 receives the instruction in step S721, creates and displays the route object of the first section according to the received instruction (step S722).

In step S1406, the evacuation simulation software 120 passes the position information of the first speed section, the position information of the second speed section, and the position information of the warp section 820 to the CAD software 110 in chronological order. Instruct to draw one polygonal figure (polygonal object) connected with the position data as vertices in order.

Also, set the color to gray 4, set the pedestrian ID in the first class, set the "normal section" in the second class, and set the "second speed" in the third class. Instruct. After that, the process is performed in step S717 of FIG.

In addition, among the line segments in the polygon, an instruction is given to set the transparency of the line segments of the first section and the warp section to 100%.

The CAD software 110 receives the instruction in step S721, creates and displays the route object of the first section according to the received instruction (step S722).

By the processing of step S1405 and step S1406, the route object corresponding to the pedestrian icon is created so as to be separately selectable according to the moving speed (walking speed) of the pedestrian.

In addition, the route object corresponding to the pedestrian icon can be identified and displayed according to the moving speed (walking speed) of the pedestrian.

Therefore, the user of the evacuation simulation software can easily confirm the place where the speed of the pedestrian has decreased and the place of the normal speed as a result of the evacuation simulation in the design study.

FIG. 15 shows an example of creating and displaying an object for each speed. For example, 1501 is the root object of the first velocity group and 1502 is the root object of the second velocity group.

As described above, according to the third embodiment of the present invention, there is provided a mechanism that makes it possible to easily display the evacuation position of an evacuee according to the speed information specified from the position history. can do.

As described above, according to the present invention, it is possible to provide a mechanism that makes it possible to easily display the evacuation position of an evacuee according to the information of the position history.

<Other embodiments>
In the above-described embodiment, the evacuees = pedestrians have been described, but the evacuees are not necessarily limited to pedestrians. For example, when a person's icon is placed on a vehicle and moved, the person's icon appearing on the vehicle indicates an evacuee.

Further, in the above-described embodiment, in consideration of reducing the time and effort for selecting the object, the root object of the normal section is generated as a polygon and the warp section is made transparent. You may divide the polygon into warp sections and generate multiple polygons. Specifically, the evacuation simulation software 120 passes only the data of the normal section 810 to the CAD software 110 in step S716, and instructs the CAD software 110 to create (plural) polygons by connecting the continuous sections. This makes it possible to omit the process of making only the line segment of the warp section transparent.

Further, in the above-described embodiment, the object ID of the pedestrian icon, the normal section, and the warp section class are instructed to be set for each route object, but for example, the selection and display of each object using a layer are used. It may be easy to switch between hiding. Specifically, the evacuation simulation software 120 instructs the CAD software 110 to create a layer of the "normal section" for the drawing in step S716, and the route object of the normal section is added to the layer of the created "normal section". Instruct the CAD software 110 to belong to. Further, in step S717, the CAD software 110 is instructed to create a layer of the "warp section" for the drawing, and the CAD software 110 is instructed to belong the root object of the warp section to the layer of the created "warp section". do. The CAD software 110 creates an object and each layer according to the instruction, and stores each root object in association with each layer. CAD software 110 provides a function to switch the display / non-display of objects for each layer, and a function to select only objects belonging to a specific layer at once. Users can use this function to create root objects for normal sections. , The root object of the warp section can be selected separately. In addition, the root object of the normal section and the root object of the warp section can be displayed / hidden at once.

In addition, the route object in the warp section indicates from which warp region the pedestrian moved to which warp region, which is different from the movement locus in which the pedestrian actually walked and moved. Therefore, for example, a simple diagram with a small warp area may not be displayed.

Therefore, for example, the root object of the warp section may be hidden at first. Specifically, the evacuation simulation software 120 instructs the CAD software 110 to hide the route object of the created warp section in step S717, and the CAD software 110 does not hide the route object of the warp section according to the instruction. Display only the root object of the normal section. In the CAD software 110, it is possible to select a class for selecting a root object in a warp section and to switch between display and non-display. This makes it possible for the user to confirm that there are two different sections, one is a section in which the pedestrian is not walking and the other is a section in which the pedestrian has walked.

Further, in the case of a simple diagram in which the number of root objects in the warp section is small, that is, the number of warp areas is small, the root object in the warp section may be hidden. Specifically, the evacuation simulation software 120 counts the number of objects in the warp section instructed to be created in step S717, and determines whether the number is equal to or less than a predetermined number. It is assumed that the predetermined number of values are stored in the external memory in advance (for example, 10). When the number of route objects in the warp section instructed to be created is less than or equal to a predetermined number, the evacuation simulation software 120 instructs the CAD software 110 to hide the route objects in the created warp section, and the CAD software 110 is concerned. According to the instructions, hide the root object of the warp section and display only the root object of the normal section. When the number of root objects in the warp section instructed to be created is larger than the predetermined number, the CAD software 110 is instructed to display the root objects in the created warp section. The CAD software 110 displays the root object of the warp section according to the instruction.

The present invention can be implemented as, for example, a system, an apparatus, a method, a program, a storage medium, or the like, and specifically, the present invention may be implemented as a system composed of a plurality of devices, or may be mounted as a single device. It may be mounted as a device consisting of.

For example, in the above-described embodiment, the evacuation simulation software 120 performs the processing of steps S503 to 513 in FIG. 5, the processing of steps S704 to S718 in FIG. 7, and the processing of FIG. 14, for example, CAD software 110. And the evacuation simulation software 120 are integrated, and the CAD software 110 may execute all the processes of FIGS. 5, 7, and 14.

Further, for example, the present invention can be implemented as the following information processing system.
