  It should be noted that any combination of the above-described constituent elements and a representation of the present invention converted between a method, an apparatus, a system, etc. are also effective as an aspect of the present invention.

  According to the present invention, a user interface with better operability can be provided.

It is a figure which shows the example of the game screen controlled by the game device which concerns on embodiment. It is a figure which shows the structure of the game device which concerns on embodiment. It is a figure which shows the external appearance of a controller.

  In the embodiment, a display device using an input device including an interface capable of inputting a direction, such as an analog stick or a direction key, and a sensor such as an acceleration sensor or a gyroscope for detecting a position or a posture. A technique for moving targets such as characters, objects, and gun sights displayed on the screen will be described. In the present embodiment, an example of moving the gun aim displayed on the screen in a game of shooting a character with a gun will be described.

  FIG. 1 shows an example of a game screen controlled by the game device according to the embodiment. On the game screen, a game field in which the character 174 is arranged and a gun sight 180 operated by the player are displayed. The player operates the controller to move the aim 180 up, down, left and right within the game screen, shoot the gun with the aim 180 aligned with the character 174, and defeat the character 174.

  FIG. 2 shows a configuration of the game apparatus 10 according to the embodiment. The game apparatus 10 includes a controller 20, a control unit 40, a game data holding unit 60, and a display device 68. The controller 20 includes an input interface 30, a three-axis acceleration sensor 32, and a three-axis gyro sensor 34. The control unit 40 includes a first reception unit 41, a second reception unit 42, a movement control unit 43, a game control unit 44, and a screen generation unit 66. In terms of hardware components, these configurations are realized by a CPU of a computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are illustrated. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  FIG. 3 shows the external appearance of the controller 20. On the upper surface of the controller 20, as an input interface 30, a button 22 including a direction key 21, a Δ button, a □ button, a ○ button, and an X button and analog sticks 23 and 26 are provided. Further, an L1 button 24a, an L2 button 24b, an R1 button 25a, and an R2 button 25b are provided on the side surface of the controller 20 as the input interface 30. In the present embodiment, the analog stick 23 is assigned a function of moving the aim in the input direction, and the button 22 is assigned a function of shooting a gun.

  The triaxial acceleration sensor 32 incorporates a weight designated by the beam, and detects the acceleration in the XYZ triaxial directions of the controller 20 by detecting a change in the position of the weight due to the acceleration. The triaxial acceleration sensor 32 may be a mechanical, optical, or semiconductor acceleration sensor. Since the triaxial acceleration sensor 32 can detect the relative angle between the direction of gravity acceleration and the XYZ triaxial directions of the controller 20, the attitude of the controller 20 can be calculated. Further, the speed can be calculated by integrating the accelerations in the directions of the three axes, and the movement amount can be calculated by further integrating.

  The triaxial gyro sensor 34 detects the angular velocities of the controller 20 in the XZ plane, the ZY plane, and the YX plane. The three-axis gyro sensor 34 may be a rotary or vibration type mechanical gyro sensor, or may be a fluid type or optical gyro sensor. By integrating the angular velocities around the three axes detected by the three-axis gyro sensor 34, the amount of rotation around the three axes can be calculated. The input signal received by the input interface 30 and the sensor signals detected by the triaxial acceleration sensor 32 and the triaxial gyro sensor 34 are transmitted to the game apparatus 10 at a predetermined cycle.

  The game control unit 44 executes a game program based on the input signal and sensor signal received from the controller 20 operated by the player, and controls the game. The game data holding unit 60 holds game field data and data such as characters and objects arranged in the game field. The screen generation unit 66 generates a game screen controlled by the game control unit 44 and causes the display device 68 to display the game screen.

  The first receiving unit 41 receives an input of the direction and speed for moving the aim from the analog stick 23. The first accepting unit 41 accepts the direction in which the analog stick 23 is tilted as a direction for moving the aim, and accepts the angle in which the analog stick is tilted as the speed for moving the aim. The movement control unit 43 moves the aim in the direction in which the analog stick 23 is tilted at a speed corresponding to the tilted angle.

  The second receiving unit 42 receives information regarding the position or orientation of the controller 20 from the triaxial acceleration sensor 32 and the triaxial gyro sensor 34. The second reception unit 42 receives the direction in which the controller 20 has been moved or tilted as the direction in which the aim is moved, and receives the amount of change in the position or angle of the controller 20 as the amount of movement of the aim. The movement control unit 43 moves the aim in the direction in which the controller 20 is moved or tilted by an amount corresponding to the amount of change in position or angle.

  The movement control unit 43 holds a coordinate value on the game screen indicating the current position of the aim, and each time the screen generation unit 66 generates one frame of the screen, calculates the position of the aim in the frame. Update the current position. First, when the analog stick 23 is tilted, the movement control unit 43 calculates a first vector indicating the movement amount of the aim for each frame and adds the first vector to the coordinate value of the aim. The direction of the first vector is the direction in which the analog stick 23 is tilted, and the magnitude of the first vector is a size corresponding to the angle at which the analog stick 23 is tilted. The movement control unit 43 further indicates the amount of movement of the aim for each frame when the position or angle of the controller 20 has changed by a predetermined amount or more during the immediately preceding one frame or a predetermined number of frames. The second vector is calculated and added to the aiming coordinate value. The direction of the second vector is a direction in which the position or angle of the controller 20 has changed, and the magnitude of the second vector is a magnitude corresponding to the amount of change in the position or angle of the controller 20. Thereby, the position of the aim in the next frame is calculated.

  The movement control unit 43 may calculate the amount of change in the relative position from the reference position using the position of the controller 20 at a predetermined timing as the reference position. Similarly, the movement control unit 43 may calculate the amount of change in the relative angle from the reference posture with the posture of the controller 20 at a predetermined timing as the reference posture. The predetermined timing is, for example, when the game apparatus 10 or the controller 20 is turned on, or when the game executed by the game control unit 44 is started, by the game control unit 44 by the reference position or reference posture of the controller 20. When calibration is performed, when the operation mode is changed in the game control unit 44, when a predetermined operation input to the input interface 30 of the controller 20 is performed, an operation input to the input interface 30 is predetermined. It may be when the position or posture of the controller 20 has not been changed for a predetermined period or longer. In the real world, the movement control unit 43 may calculate the angle of the controller 20 with respect to the horizontal plane, with the posture in which the top surface of the controller 20 shown in FIG.

  As described above, in this embodiment, the player can move the target position by operating the analog stick or by changing the position or posture of the controller. When operating the analog stick, while the analog stick is tilted, the object continues to move in the tilted direction, but when changing the position or posture of the controller itself, the controller is changed from the reference position or reference posture. Only move the target. Therefore, the player may use an analog stick to move the object greatly, and change the position or orientation of the controller to move the object small and finely adjust the position. Thus, in order to move the position of the same object, a user interface with good operability can be provided by preparing a plurality of operation methods with different sensitivities. In addition, when moving the aim by changing the position or posture of the controller, the aim can be moved by an amount corresponding to the amount of change in the position or posture regardless of the speed at which the position or posture is changed. It is possible to provide a user interface that can be finely adjusted.

  Since the movement control unit 43 does not move the target position when the position or posture of the controller 20 does not change by a predetermined amount or more during a predetermined period, the movement of the player is excessively reflected in the target position. Can be suppressed. By adjusting the threshold of the change in the position or orientation of the controller 20 for moving the target, it is possible to reflect the camera shake of the player in the change in the target position to some extent. Thereby, it is possible to produce an effect that the player actually has a gun. The movement control unit 43 may move the viewpoint position of the camera when rendering the game field. In this case, it is possible to produce a camera shake effect as if the player actually has a camera.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to each component and combination of processing processes, and such modifications are within the scope of the present invention.

  In the embodiment, the position and orientation of the controller are detected using the 3-axis acceleration sensor and the 3-axis gyro sensor, but the position or orientation of the controller may be detected using any known technique. For example, the position or orientation of the controller may be detected by imaging the controller with a camera.

  In the embodiment, the example in which the sight displayed on the game screen is moved by the input of the analog stick and the change in the position or posture of the controller has been described. However, in another example, the sight is fixed at a predetermined position on the screen. Then, the line-of-sight direction or viewpoint position when generating the game screen may be changed. Also in this case, the line-of-sight direction or the viewpoint position may be greatly changed by an input from an analog stick or the like, and the line-of-sight direction or the viewpoint position may be changed small by a change in the position or posture of the controller. The line of sight direction may be changed by inputting an analog stick or the like, and the viewpoint position may be changed by changing the position or posture of the controller, or conversely, the viewpoint position may be changed by inputting an analog stick or the like. The line-of-sight direction may be changed by changing the position or posture. Also, the direction of the line of sight or the viewpoint position may be changed by inputting an analog stick or the like, and the position of the target on the game screen may be changed by changing the position or posture of the controller. Thus, the position of the target on the game screen may be changed, and the line-of-sight direction or the viewpoint position may be changed by changing the position or posture of the controller.
