FIG. 8 is a diagram illustrating the dependence of the suppression coefficient on the amount of approach;

1. Overview FIG. 1 is a diagram illustrating a virtual space 50 in the present embodiment. In this example, the virtual space 50 is a two-dimensional virtual space. The virtual space 50 has an object 52. The object 52 is a virtual object arranged in a virtual space, for example, an icon, a character (a person, an animal, a monster, etc.), a building (a house, a tower, a castle, etc.), a natural object (a mountain, a river, a tree, a rock, etc.). Etc.) and at least one representing a workpiece (car, block, etc.) that does not settle in the field. In the example of FIG. 1, a plurality of objects 52 each representing an icon are arranged.

  A virtual camera (not shown) is provided in the virtual space 50, and an image virtually captured by the virtual camera is displayed on a display device. The virtual camera itself may be inside the virtual space 50 or outside the virtual space 50. The region 53 represents a region photographed by the virtual camera, that is, a region displayed on the display device. The area 53 moves according to a user's operation input. That is, the image displayed on the display device scrolls according to the operation input. A free movement range 54 is set for the area 53. The area 53 moves freely in response to an operation input if it is inside the free movement range 54, but outside the free movement range 54, the movement of the area 53 is compared with the case where it is inside the free movement range 54. And be restricted. Note that, in this example, the region 53 cannot exceed the free movement range 54 at all. Under certain restrictions, at least a portion of the area 53 may go outside the free movement range 54.

  FIG. 2 is a diagram illustrating a state in which the region 53 moves within the free movement range 54 in the comparative example. In the comparative example, the region 53 moves in a range that does not protrude outside the free movement range 54. Now, consider an example in which the speed V is applied to the region 53 from the position shown in FIG. 2A in the lower right direction (oblique direction), and the region 53 moves. When the right end of the area 53 moved in the lower right direction moves to a position where it comes into contact with the right end of the free movement range 54 (FIG. 2B), the area 53 cannot move further to the right. In this state, if the moving speed in the lower right direction (calculated or virtual) is not zero (for example, when an operation input for moving the area 53 to the lower right is given), If both the directional component and the downward component are not zero, the region 53 cannot move to the right, and therefore moves only downward (FIG. 2C). In this case, the area 53 may be moving in a direction not intended by the user.

  FIG. 3 is a diagram illustrating a state in which the region 53 moves within the free movement range 54 in the present embodiment. FIGS. 3A and 3B are the same as FIGS. 2A and 2B. In the state of FIG. 3B, that is, when the area 53 moves to the right end of the free movement range 54, if the area 53 has a moving speed of a lower right direction, the area 53 moves downward. At this time, the amount of downward movement is suppressed more than in the case of FIG. Further, at this time, the area 53 also moves to the right under the determined restriction (FIG. 3C). The area 53 goes out of the free movement range 54 and then returns to the free movement range 54 (FIG. 3D). That is, when the moving speed V becomes zero, the area 53 finally moves to a position that falls within the free movement range 54. According to this example, movement of the region 53 in a direction not intended by the user can be suppressed. Hereinafter, the configuration and operation of an apparatus that provides such a user interface will be described.

2. Configuration FIG. 4 is a diagram illustrating a functional configuration of the information processing apparatus 1 according to the embodiment. The information processing device 1 includes a receiving unit 11, a display control unit 12, and a movement control unit 13. The accepting unit 11 accepts an operation input by a user for moving an area 53 that is a part of a predetermined area (in this example, the virtual space 50). The display control means 12 causes the display means 20 to display the image of the area 53. The display unit 20 is a function provided by an external device different from the information processing device 1 in this example, and displays at least one of a character and an image. The movement control means 13 moves the area 53 based on the operation input. When the region 53 has a predetermined positional relationship with the virtual space 50, the movement control unit 13 suppresses movement in a predetermined direction and moves the display region. In this example, the predetermined positional relationship is a positional relationship in which the region 53 is going to go out of the free movement range 54. The predetermined direction is a direction that intersects the direction in which the region 53 is going to go out of the free movement range 54.

  FIG. 5 is a diagram illustrating a hardware configuration of the information processing apparatus 1. In this example, the information processing device 1 is a game device for executing a video game. The information processing device 1 is a computer device having a CPU 101, a memory 102, an external memory IF 103, an input / output IF 104, and a communication unit 105. The controller 2 is used for operating the information processing device 1. Further, the information processing device 1 is connected to the display device 4. The display device 4 is a device that displays information including at least one of an image and a character, and includes a display (a liquid crystal panel, an organic EL (Electro-Luminescence) panel or the like), and a drive circuit. In this example, the information processing device 1 is a so-called stationary game device, and does not include the display device 4. The display device 4 is an external device, for example, a television receiver. Note that the information processing device 1 may include the display device 4.

  The CPU 101 is a device that controls each unit of the information processing device 1 and performs various calculations. The memory 102 is a storage device that stores programs and data, and has, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory). The external memory IF 103 is an interface that reads and writes programs and data from and to an external memory 3 (for example, an optical disk, a magnetic disk, or a semiconductor memory) that stores a program (for example, a game program) and data. The input / output IF 104 is an interface that mediates signals with an input / output device (the display device 4 in this example). The communication unit 105 is a device that communicates with the controller 2, and has, for example, an antenna and an amplifier. By executing a program (for example, a game program) stored in the external memory 3 or the memory 102, a function (for example, a video game) related to the program is realized in the information processing device 1.

  The controller 2 is a device for inputting an instruction to the information processing device 1. In this example, the controller 2 further has a function of displaying an image according to a signal transmitted from the information processing device 1. The controller 2 has a CPU 201, a touch screen 202, and a communication unit 203. The CPU 201 is a device that controls each unit of the controller 2 and performs various calculations using a memory (not shown). The touch screen 202 is a device having both a function of displaying information and a function of inputting an instruction, and includes, for example, a display and a driving circuit, and a touch sensor provided on a surface of the display. The communication unit 203 is a device that communicates with the information processing device 1, and has, for example, an antenna and an amplifier.

  In this example, an image of the area 53 in the virtual space 50 is displayed on at least one of the display device 4 and the touch screen 202 by a program (game program, system software, or a combination thereof) stored in the external memory 3 or the memory 102. Is provided. The area 53 moves in the virtual space 50 according to an operation input via the controller 2. The CPU 101 executing this program is an example of the receiving unit 11, the display control unit 12, and the movement control unit 13. At least one of the display device 4 and the touch screen 202 is an example of the display unit 20.

3. Operation FIG. 6 is a flowchart showing the operation of the information processing apparatus 1. Before the flow of FIG. 6 starts, a program for displaying an image of the area 53 in the virtual space 50 is executed. Here, an example will be described in which an image of the area 53 is displayed on the touch screen 202, and an instruction corresponding to an operation input by a user on the touch screen 202 is input to the information processing apparatus 1. In this example, the process of FIG. 6 is repeatedly executed at a predetermined cycle (for example, 16.7 milliseconds corresponding to 60 Hz). The unit period of this processing is called a “frame”.

  Operations on the touch screen 202 include “drag” and “flick”. The drag is an operation of tracing the touch screen 202 with a finger, that is, an operation of moving a touch position while maintaining a touched state. A flick is an operation of quickly touching the touch screen 202 with a finger, that is, an operation of dragging the touch screen 202 at a speed higher than a predetermined reference value and then releasing the finger from the touch screen 202. The moving speed of the region 53 is determined according to these operations, and an image of the region 53 that has moved according to the determined moving speed is displayed.

  In step S101, the CPU 101 receives an operation input. Details are as follows. The signal indicating the user's operation input (hereinafter, referred to as “operation input signal”) transmitted from the controller 2 includes the coordinates of the position touched on the touch screen 202 (hereinafter, referred to as “real coordinates”). When the touch screen 202 is not touched in the current frame, the operation input signal includes a null value. The CPU 101 converts the real coordinates into coordinates indicating a position in the virtual space 50 (hereinafter referred to as “virtual coordinates”, and a point indicated by the virtual coordinates is referred to as “virtual point”).

  The memory 102 sequentially stores the virtual coordinates in each frame in a past predetermined period (for example, from the frame where the ongoing drag or the ongoing flick is started to the latest frame). The CPU 101 writes the virtual coordinates in this frame into the memory 102.

  In step S102, the CPU 101 calculates the moving speed of the area 53. In this example, the CPU 101 calculates the moving speed of the area 53 using at least a part of the plurality of virtual coordinates stored in the memory 102. The moving speed may be specifically calculated by any method. For example, the moving speed is calculated by multiplying the accumulated operation input by a coefficient. Alternatively, the moving speed may be calculated using a vector sum of the vector obtained by multiplying the moving speed in the previous frame by a vector from the starting point of the drag to the target point and the moving speed in the previous frame. Further alternatively, the moving speed may be calculated by another method.

  In step S103, the CPU 101 calculates the position of the area 53 after the movement (correctly, a candidate for the position after the movement). The current position of the area 53, the moving speed, and the frame period are used to calculate the position after the movement. The position of the region 53 is represented by the position of a representative point (for example, the upper left vertex).

In step S104, the CPU 101 determines whether the area 53 after the movement and the free movement range 54 satisfy a predetermined positional relationship. In this example, the predetermined positional relationship is such that the end of the area 53 after the movement protrudes from the free movement range 54. The CPU 101 is, for example,
x1 <xmin ... (1)
x2> xmax (2)
y1 <ymin ... (3)
y2> ymax (4)
It is determined whether at least one of the conditions is satisfied. Note that x1 and x2 indicate the x coordinates of the left end and the right end of the area 53 after the movement, respectively. y1 and y2 indicate the y coordinates of the lower end and the upper end of the area 53 after the movement. xmin and xmax indicate the x coordinates of the left end and the right end of the free movement range 54, respectively. ymin and ymax indicate the y coordinates of the lower end and the upper end of the free movement range 54, respectively. In this example, the rightward direction is the positive direction of the x-axis, and the upward direction is the positive direction of the y-axis. When it is determined that the area 53 and the free movement range 54 satisfy any of the predetermined positional relationships (1) to (4) (S104: YES), the CPU 101 shifts the processing to step S106. . When it is determined that the area 53 and the free movement range 54 do not satisfy the predetermined positional relationship (S104: NO), the CPU 101 shifts the processing to step S105.

  In step S105, the CPU 101 moves the area 53 to the position calculated in step S103. When the processing in step S105 is completed, the CPU 101 shifts the processing to step S108.

  In step S106 and step S107, the coordinates of the specific direction and the direction other than the specific direction (hereinafter, referred to as “non-specific direction”) are determined. That is, only the coordinates in the specific direction are determined in step S106, and only the coordinates in the non-specific direction are determined in step S107. In step S106, the CPU 101 suppresses movement in a direction (hereinafter, referred to as a “specific direction”; an example of a predetermined direction) according to the positional relationship satisfied in step S104. The direction according to the positional relationship is a direction different from the direction in which the end of the area 53 after the movement protrudes, in this example, a direction orthogonal to the direction in which the end protrudes. For example, when the condition of Expression (1) or (2) is satisfied, the y direction is the specific direction, and when the condition of Expression (3) or (4) is satisfied, the x direction is the specific direction. When both the formula (1) or (2) and the formula (3) or (4) are satisfied, no specific direction exists (neither the x direction nor the y direction is a specific direction).

The CPU 101 suppresses movement in a specific direction according to, for example, the following equation (5).
pr (j) -p (j-1) = k {pc (j) -p (j-1)} (5)
By solving equation (5) for pr (j), the following equation (6) is obtained.
pr (j) = k · pc (j) + (1−k) · p (j−1) (6)
The CPU 101 determines the coordinates calculated by Expression (6) as the coordinates of the area 53 in the specific direction. Here, pr (j) indicates the position after the suppressed movement of the j-th frame (current frame). pc (j) indicates the position after the movement calculated in step S103 of the j-th frame. p (j-1) indicates the position in the (j-1) th frame (the immediately preceding frame). k is a coefficient (hereinafter, referred to as “suppression coefficient”) indicating the degree of movement suppression. In this example, the coefficient k is determined according to the distance between the area 53 and the free movement range 54 in the non-specific direction. This correction is not performed for directions other than the specific direction.

  FIG. 7 is a diagram illustrating a distance between the area 53 and the free movement range 54. In this example, the distance between the region 53 and the free movement range 54 is the distance between the ends, and more specifically, the portion of the region 53 that protrudes from the free movement range 54. This is the difference between the maximum value (or minimum value) of the coordinates in the coordinate axis direction and the maximum value (or minimum value) of the coordinates in the coordinate axis direction for the free movement range 54. In the example of FIG. 7A, the region 53 protrudes in the positive x-axis direction of the free movement range 54, and the difference between the maximum value of the x coordinate of the region 53 and the maximum value of the x coordinate of the free movement range 54 is different. , The distance d between the area 53 and the free movement range 54. FIG. 7B shows an example in which the shape of the free movement range 54 is not rectangular. In this example, the region 53 protrudes in the negative y-axis direction of the free movement range 54, and the difference between the minimum value of the y coordinate of the region 53 and the minimum value of the y coordinate of the free movement range 54 This is the distance d from the moving range 54. In the following example, the distance between the area 53 and the free movement range 54 is referred to as “entrance amount” from the viewpoint that the area 53 has entered the outside of the free movement range 54.

  FIG. 8 is a diagram illustrating the dependence of the suppression coefficient on the amount of approach. The vertical axis indicates the suppression coefficient k, and the horizontal axis indicates the approach amount d in the non-specific direction. In this example, the coefficient k has a value in the range of 0 <k <1, and a smaller value indicates that movement is suppressed. In this example, the larger the amount of entry in a non-specific direction (for example, the x direction), the more the movement in a specific direction (for example, the y direction) is suppressed. In this example, since the coefficient k is less than 1, the region 53 and the free movement range 54 are located at a predetermined position more than the movement distance in a specific direction when the region 53 and the free movement range 54 are not in a predetermined positional relationship. The movement in the specific direction is suppressed so that the movement distance in the specific direction in the relationship is smaller. Further, in this example, since the coefficient k is larger than 0, the area 53 moves in a specific direction even after being suppressed (that is, the movement amount is not zero).

  FIG. 6 is referred to again. In step S107, the CPU 101 determines the position after the movement in the non-specific direction (that is, determines the amount of movement). As the position after the movement in the non-specific direction, the position calculated in step S103 is used in principle. However, when the approach amount d exceeds the threshold value (upper limit) thd, the CPU 101 determines the position after the movement so that the approach amount d does not exceed the threshold value thd. For example, when the approach amount d exceeds the threshold thd, the CPU 101 corrects the position calculated in step S103 so that d = thd. In this example, the threshold value thd of the approach amount (that is, the allowable approach amount) is determined according to the moving speed (more specifically, the non-specific component of the moving speed) calculated in step S102. More specifically, CPU 101 increases the value of threshold thd as the moving speed increases.

  When the end of the area 53 is out of the free movement range 54, the CPU 101 performs a process for producing an effect of reducing the moving speed as compared with the case where the area 53 is within the free movement range 54. The process of producing the effect of reducing the moving speed is, for example, a process of changing the coefficient used in the formula for calculating the moving speed in a direction in which the moving speed decreases, a process of providing a virtual operation input for reducing the moving speed, or Including these combinations.

  In step S108, the CPU 101 outputs a signal for drawing the image of the area 53 at the position corresponding to the coordinates stored in the memory 102 on the touch screen 202. The touch screen 202 draws an image according to the signal received via the communication unit 105 and the communication unit 203. When the next frame is reached, the CPU 101 executes the processing of steps S101 to S108 again.

  As described above, according to the present embodiment, when the area 53 is moved near the boundary of the free movement range 54, the area 53 in a direction not intended by the user is suppressed.
