JP 2019-12430 A

The movement speed may change depending on the situation when a person moves. For example, it slows down because it is muddy and difficult to walk, or because it is difficult to walk due to an uphill slope. Also, for example, there is a downhill slope and the speed increases. Also, in the movement of a wheelchair or the like, the speed is slow at the start of movement, and then gradually accelerates. In order to simulate such a change in speed, there is a method of arranging a variable speed region that changes the speed of the moving object and changing the speed of the moving object that passes over it. When the movement speed changes depending on the situation when moving, it is natural that the speed does not change suddenly but changes smoothly. Conventionally, in order to smoothly change the speed of a moving object, it has been necessary to set a plurality of speed change areas that divide the speed from the current speed to the target speed, and move the object over these. However, there is a problem in that creating a plurality of shift areas one by one is a laborious operation requiring many operations.

SUMMARY OF THE INVENTION In view of at least one of the above problems, it is an object of the present invention to provide a technique that allows setting a smooth change in speed of a moving object with better operability.

The electronic device of the present invention comprises acquisition means for acquiring a set value relating to speed between a first position and a third position input by a user operation; Setting for setting the set value related to the velocity of the position 2 based on the set value of the first position and the set value of the third position acquired by the acquisition means, without the user inputting the set value. means for moving the moving object at a velocity based on a velocity setting value set for each position when the moving object moves through the first position, the second position, and the third position; each of the first to third positions corresponds to one of a plurality of segmented regions included in a specific divided figure. do.

It is possible to set the event that triggers the appearance of the shifting area grid (trigger, condition) and the event that causes the shifting area grid to disappear. is. For the initial state, it is possible to set either "appearing" or "not appearing" of the shift area grid as a set value. When "fixed" is set as the appearance method, the analysis process (simulation) is controlled so that the shift area grid always appears. When "Variable (time)" is set as the appearance method, in the analysis process (simulation), it is controlled so that the shift area grid appears according to the setting value of the appearance time, and the speed is changed according to the setting value of the disappearance time. Controlled to make the region grid disappear. When "variable (event)" is set as the appearance method, in the analysis process (simulation), the shifting area grid is controlled to appear and disappear according to the occurrence of the event with the setting value of the event to appear. The shift area grid is controlled to disappear in response to the occurrence of the event of the set value of the event.

Returning to FIG. 4 , in step S<b>405 , the CPU 101 receives input of setting values for each setting item of the pop-up dialog 330 according to the user's operation of the operation unit 106 .

In step S<b>406 , CPU 101 determines whether or not “speed” has been set as the setting value of the shifting method of pop-up dialog 330 according to the user's operation of operation unit 106 . If "speed" is set as the set value of the shift method, the process proceeds to step S407. , the process proceeds to step S408.

For example, the CPU 101 sets the speeds of a plurality of segmented regions divided according to the set value of the number of divisions, based on bilinear interpolation using the set values of the upper left, lower left, upper right, and lower right end points of the speed setting. calculate. For example, if the number of divisions in the horizontal direction is m and the number of divisions in the vertical direction is n, the rectangle indicating the range of the shifting area grid is divided into (m×n) divided areas. . It is also assumed that the upper left setting value is Lt, the lower left setting value is Lb, the upper right setting value is Rt, and the lower right setting value is Rb. In this case, the segmented area containing the upper left corner point is the first segmented region in the horizontal direction and the first segmented region in the vertical direction (1, 1), and the segmented region containing the lower right corner point is the mth segmented region in the horizontal direction and the first segmented region in the vertical direction. Assuming that the n-th segmented area (m, n), the set value V(i , j) are calculated by the following (Equation 1).

In step S411, the CPU 101 calculates the range of each segmented area of the transmission area grid based on the horizontal and vertical set values of the size of the rectangle indicating the range of the transmission area grid and the number of divisions. For example, the CPU 101 determines the coordinates of the four vertices of each segmented region for a plurality of segmented regions within a rectangle divided according to the set number of divisions, and stores the coordinates in the memory 102 .

Returning to FIG. 2 , in step S<b>217 , the CPU 101 determines whether or not there is an instruction to save the file in accordance with the user's operation on the operation unit 106 . If there is an instruction to save the file, the process proceeds to step S218, and if there is no instruction to save the file, the process proceeds to step S219.

In step S<b>218 , the CPU 101 saves the edited drawing file (including various setting values recorded in the memory 102 ) in the nonvolatile memory 103 . The saved file can be read in step S203. After that, the process returns to step S202.

In step S<b>219 , the CPU 101 determines whether or not there is an instruction to execute analysis (execute simulation) according to the user's operation of the operation unit 106 . If there is an instruction to perform analysis, the process proceeds to step S220, and if there is no instruction to perform analysis, the process proceeds to step S221.

In step S<b>220 , the CPU 101 performs drawing analysis processing and controls the display 105 to display a simulation in which the moving objects 303 and 304 move toward the destination object 302 . After that, the process returns to step S202.

In step S221, the CPU 101 determines whether or not there is an instruction to end the processing of the flowchart in FIG. If there is an instruction to end, the CPU 101 ends the processing of the flowchart in FIG. 2, and if there is no instruction to end, the process returns to step S202.

Here, the analysis processing (simulation) in step S220 of FIG. 2 will be described. When the analysis processing (simulation) is started, the CPU 101 moves at a moving speed set for each moving object to a set destination (destination) along a route that does not pass through objects such as obstacle objects and wall objects that hinder the movement of moving objects. object) to initiate movement of the moving object. A moving object is, for example, a person (pedestrian) or a wheelchair. Also, this simulation is a simulation of moving a moving object on a drawing, such as a simulation of the movement of people in a building, or a simulation of the movement of people attending an event such as a concert venue. Alternatively, for example, an evacuation simulation in which a moving object moves to a destination such as an evacuation area or an evacuation exit may be used.

(1) When controlling the moving object to move toward the destination object, the CPU 101 determines for each moving object whether or not the coordinates of the current position of the moving object are included in the shifting area that has already appeared. When the coordinates of the current position of the moving object are included in the shifting area that has already appeared, the CPU 101 changes the moving speed of the moving object to the moving speed corresponding to the shifting area and controls the moving object to move. . The moving speed corresponding to the variable speed region is (moving speed set for each moving object×speed magnification) or (absolute speed) defined in the variable speed region. If the coordinates of the current position of the moving object are not included in the variable speed area that has already appeared, the CPU 101 controls the moving object to move at the moving speed set for each moving object.

(2) When controlling the moving object to move toward the destination object, the CPU 101 determines whether or not the current time in the simulation is the time when the shifting area appears or disappears. When the current time in the simulation is the time at which the shift area appears or disappears, the CPU 101 causes the target shift area to appear if there is a shift area to appear, and if there is a shift area to disappear, the target shift area disappears. Let

(3) When controlling the moving object to move toward the destination object, the CPU 101 determines whether or not an event that causes the shifting area to appear or disappear has occurred. When an event that causes a shift area to appear or disappear occurs, the CPU 101 causes the target shift area to appear if there is a shift area to appear in response to the occurrence of the event, and if there is a shift area to disappear in response to the occurrence of the event. Disappears the target shift area.

The CPU 101 repeats the control of (1) to (3) until the analysis ends or the movement of all the moving objects to the last destination (destination object with the largest destination number) is completed. Control to move toward the destination object.

In the execution of the above-described analysis processing (simulation), examples of places where the shifting area grid is arranged from the beginning include the movement start point of the moving object, entrances and exits, and inclined portions. This is because the moving object does not normally move at full speed from the beginning at the movement start point or the doorway, and the part with a slope is generally faster on a downward slope and slower on an upward slope. Also, examples of events that cause the shifting area grid to appear include the occurrence of flooding and the occurrence of fire. This is because when a flood occurs, it becomes difficult to walk due to mud or the like, and when a fire occurs, it becomes difficult to walk due to a posture to avoid smoke, or because the operation of a sprinkler makes it difficult to walk. Examples of events that cause the shift area grid to disappear include completion of drainage, fire extinguishing, stoppage of sprinklers, etc., contrary to events that cause the shift area grid to appear.

In the above description, the shifting area grid and its partitioned areas are assumed to be rectangular areas, but the shifting area grid can be arranged in a desired form by performing the following operations on the generated shifting area grid. be. For example, in the shifting area grid, by overlapping an obstacle object (obstacle graphic) on the part to be trimmed (the part not to be walked), it is possible to prevent the moving object from moving in that part, and the desired shape of the shifting area can be obtained. It can be a grid. In addition, after releasing the group of the transmission area grid and making each divided area into a single object, by directly processing with the notch function of CAD software etc. to change the shape, the desired shape of the transmission can be obtained. It can be a region grid.

Next, effects will be described. If the user sets the speed or speed multiplier for the end regions of the variable speed region grid, the CPU 101 automatically calculates and sets the speed setting values for the regions between them so as to change smoothly. A smooth speed change can be easily set with a small number of operations.

In addition, when the speed change area grid is displayed on the drawing, the gradation display is used so that smooth speed changes can be seen visually, so the user can intuitively understand what kind of speed setting is being made. can be presented to

By combining a plurality of speed change area grids, it is possible to control the moving speed of the moving object to change from increasing to decreasing or from decreasing to increasing. For example, as shown in FIG. 6(b), a speed change area grid 601 is created in which the speed setting value is symmetrical to the speed change area grid 501, and the speed change area grid 601 is placed on the right side of the speed change area grid 501 so as to be in contact with the speed change area grid 601. Place them side by side. By combining multiple shifting area grids in this way, it is possible to create shifting areas where the change in speed is neither monotonically increasing nor monotonically decreasing. For example, according to the combination of the shifting area grid 501 and the shifting area grid 601 shown in FIG. 6B, it is possible to simulate the movement of mud that is deeper and harder to walk (the speed decreases) toward the left-right center.

In the above description, the user sets the speed setting values in the four divisional areas of the shifting area grid, namely, the upper left, the lower left, the upper right, and the lower right, and interpolates the speed setting values of the other divisional areas of the shifting area grid. An example of automatically calculating and setting by is described above. However, it is not limited to this, and in addition to the four ends of the upper left, lower left, upper right, and lower right, the central segmented area (horizontal center, vertical center, horizontal and vertical centers, respectively) ) can be set by the user, and the set values for the speeds of the other divided areas of the shift area grid may be automatically calculated and set by interpolation. In this way, the shift area grid using the shift area grid 501 and the shift area grid 601 shown in FIG. can be reduced further.

In addition, although the setting of the speed change when simulating the movement of the moving object using the simulation software has been described, the present invention is not limited to this. For moving objects that move on the screen or in the virtual space, any method can be applied as long as it is possible to set the shift region grid as described in the present embodiment on the moving path of the moving object. For example, in the production of a game, a variable speed region grid such as that of the present embodiment is applied when a plurality of variable speed regions for changing the speed of a moving object such as a character or a vehicle are set side by side along a movement path to smoothly change the speed. It is possible.
