Description

  The present invention relates to an arrangement information detection system, a game system, a program, an information storage medium, and an arrangement information detection system control method.

Conventionally, there has been known a shooting game apparatus in which a player can enjoy a pseudo shooting using a gun-type controller.
JP-A-8-71252

  In the above document, light emitters are arranged at four locations so as to surround a video screen, a CCD camera is provided on the barrel of a shooting gun, and an image including the four light emitters is photographed. Is recorded in the video RAM, and the relative position, rotation angle and inclination of the gun with respect to the video screen are calculated based on the image position information of the four light emitters recorded in the video RAM.

  According to the above method, it is not necessary to change the screen to a single color for a moment, you can play with the gun freely in your hand, and you can detect the direction, position, and tilt of the gun even if there is a black part in the game image At the same time, the distance between the screen and the gun, the rotation of the gun, and the position of the gun in the three-dimensional space can be detected.

  However, the above method has a problem that the processing load increases because it is necessary to detect the position coordinates of the light emitter from the image taken by the CCD camera.

  There is also a problem that it is difficult to detect the position of the light emitter due to the brightness of the screen.

  The present invention has been made in view of the problems as described above, and the object of the present invention is to allow the user to play the pointing device freely in his / her hand and to point and rotate the pointing device relative to the screen with a small calculation load. Another object of the present invention is to provide an arrangement information detection system, a game device, a program, and an information storage medium that can detect a tilt and an inclination.

(1) The present invention is an arrangement information detection system that detects relative arrangement information related to at least one of the position, orientation, and rotation of a pointing device and a predetermined surface,
A plurality of light emitters configured to be installed or installable near an outer periphery of a predetermined surface, and emit light of a predetermined wavelength with a time difference;
The position, orientation, and rotation of the pointing device are changed in conjunction with the position, orientation, and rotation of the pointing device to receive light from the point direction of the pointing device and to receive light of a predetermined wavelength emitted from the light emitter on the light receiving surface. A two-dimensional light position detection unit that detects a detection value for specifying a position for each light emitter;
An arrangement information calculation unit that calculates the relative arrangement information of the pointing device and the screen based on the detection value of the two-dimensional optical position detection unit;
It is characterized by including.

  The present invention also relates to a program that causes a computer to function as each of the above-described units. The present invention also relates to a computer-readable information storage medium that stores (records) a program that causes a computer to function as each unit. The present invention also relates to a method for controlling an arrangement information detection system that functions as each of the above-described units.

  The pointing device may be any device that indicates a position on a predetermined surface (or a target in the screen) or the like, and may be a shooting device such as a gun-type controller.

  The light emitter is configured to be installed or installable near the outer periphery of a predetermined surface, emits light of a predetermined wavelength such as infrared rays, and can be configured by a light source or a light emitting element of a predetermined wavelength.

  In the present invention, at least two light emitters are used. When two light emitters are used, they may be arranged at two corners located on a rectangular diagonal line on the outer periphery of the predetermined surface.

  When three or more light emitters are installed, they may be arranged on the same plane as the predetermined plane or on the same plane as the plane arranged parallel to the predetermined plane.

  Each light emitter emits light with a slight time difference so as not to emit two or more lights in a time-sharing manner in order to distinguish and recognize light emission for each light emitter. The minute time difference is, for example, a time that is obtained by time-division of 1/60 seconds in which an image of one frame is displayed by the number of light emitters, and is set as a time in which the two-dimensional light position detection unit can receive light.

The two-dimensional optical position detector uses a two-dimensional PSD (Position Sensitive) as a pointing device.
It can be realized by installing with a Detector.

  The two-dimensional PSD is located at a position where a light receiving surface (a two-dimensional plane specified by a first axis (for example, the X-axis direction) and a second axis (for example, the Y-axis direction)) hits a light having a predetermined wavelength. A voltage is generated. A two-dimensional position coordinate (X, Y) of the light receiving point is specified by using the voltage drop caused by this.

  For example, both ends in the X-axis direction are X1 and X2, and both ends in the Y-axis direction are Y1 and Y2. When a resistor is provided between X1 and X2 and Y1 and Y2, assuming that the coordinates of the light receiving point (X, Y), the voltage drops at both ends X1 and X2 in the X-axis direction in proportion to the distance between XX1 and XX2. A voltage (or current) value is output. Therefore, it can be determined how far away from the middle of X1X2 the voltage drop has occurred, based on the voltage (or current) difference between XX1 and XX2. The same applies to Y.

  Thus, since the voltage value and the current value are returned as the detection value, the coordinate value of the light receiving position (X, Y) can be obtained by comparing the returned voltage value with the initial value.

  Here, the two-dimensional PSD can detect the position coordinates of the spot light in two dimensions. For example, the optical system of the light receiving unit may be configured such that the light that has reached from the light emitter becomes spot light on the two-dimensional PSD. .

  The relative arrangement information of the pointing device and the screen includes at least one of the position, orientation, and rotation of the pointing device and the screen, and any one or two of these may be detected, or all three are detected. It may be the case.

  According to the present invention, a plurality of light emitters are caused to emit light one by one with a slight time difference. Since the system can grasp the light emission timing, the light emission history, the light emission order, and the light emission time (light emission information) of each light emitter, the light emitter corresponding to each light receiving point can be specified.

  For example, when the light is always emitted with a slight time difference, information on the light emitters emitted at time t1 may be acquired and specified based on information about the light emission order of a plurality of light emitters held in advance. .

  Alternatively, the light emission may be started by a predetermined event (for example, a shooting event), and the light receiving points may be associated with the light emitters in time series according to the light emission order.

  In general, when multiple light emitters always emit light, the light receiving points and the light emitters are associated from the shape drawn by the detected light receiving points. In this case, however, the calculation algorithm becomes complicated and the calculation load is increased. Will also increase.

  However, according to the present invention, it is possible to easily associate light receiving points and light emitters in a predetermined two-dimensional plane with a small calculation load by providing light emission with a slight time difference so that two or more light emitters do not emit light simultaneously. Can be done.

  Therefore, an arrangement information detection system, game device, program, information storage medium, and arrangement information that can be played with the pointing device freely in hand and can detect the point position, rotation, inclination, etc. with respect to the screen of the pointing device with a small calculation load A control method of the detection system can be provided.

(2) In the present invention, relative arrangement information relating to at least one of the position, orientation, and rotation of a predetermined surface and a pointing device in which a plurality of light emitters emitting light of a predetermined wavelength with a time difference are disposed in the vicinity of the outer periphery is obtained. An arrangement information detection system for detecting,
The position, orientation, and rotation of the pointing device are changed in conjunction with the position, orientation, and rotation of the pointing device to receive light from the point direction of the pointing device and to receive light of a predetermined wavelength emitted from the light emitter on the light receiving surface. A two-dimensional light position detection unit that detects a detection value for specifying a position for each light emitter;
An arrangement information calculation unit that calculates the relative arrangement information of the pointing device and the screen based on the detection value of the two-dimensional optical position detection unit;
It is characterized by including.

(3) The arrangement information detection system, game device, program, information storage medium, and arrangement information detection system control method of the present invention include:

The arrangement information calculation unit includes:
Relative arrangement information between the pointing device and the predetermined surface is calculated based on the detection value of the two-dimensional light position detection unit and the reference value.

  Here, the reference value may be a voltage value or a current value output from the two-dimensional light position detector when in a predetermined arrangement state, or a light receiving point (light emitter) in a two-dimensional plane obtained from the voltage value or the current value. The coordinate value of (detection position) may be used.

  For example, the detection result of the two-dimensional light position detection unit may be compared with the reference value, and the relative arrangement information of the pointing device and the screen may be calculated based on the comparison result.

  The reference value may be set by an initial setting input or may be set as a default value.

For example, the reference value information storage unit
As the reference value, reference light receiving position information relating to light receiving positions of light emitted from the plurality of light emitters in a predetermined two-dimensional plane when the pointing device is in a predetermined arrangement state is stored,
The arrangement information calculation unit is
Based on the detection value of the two-dimensional light position detector, the light receiving position of the light emitted from the plurality of light emitters on the light receiving surface is calculated,
The relative arrangement information between the pointing device and the predetermined surface may be calculated based on the reference light receiving position and the detected light receiving position.

(4) The arrangement information detection system, game device, program, information storage medium, and arrangement information detection system control method of the present invention include:
It further includes a reference value setting unit that sets the reference value based on the detection value of the two-dimensional light position detection unit.

  For example, an instruction for placing the pointing device in the predetermined arrangement state is output to the player, and the detection value of the two-dimensional optical position detection device when the pointing device is arranged in response to the instruction is set as a reference value. The detected light receiving position of the light emitted from the plurality of light emitters on the light receiving surface may be calculated based on the detected value, and the detected light receiving position may be set as a reference value. .

  In this way, subtle errors for each device can be absorbed.

  In the present invention, a plurality of light emitters are caused to emit light one by one with a slight time difference. Since the system can grasp the light emission timing, light emission history (transition of light emission position), light emission order and light emission time, it corresponds to the light receiving position (each light receiving point) detected for each light emitter. It is possible to specify the illuminant to be used.

  For example, when the light is always emitted with a slight time difference, information on the light emitters emitted at time t1 may be acquired and specified based on information about the light emission order of a plurality of light emitters held in advance. .

  Alternatively, the light emission may be started by a predetermined event (for example, a shooting event), and the light receiving points may be associated with the light emitters in time series according to the light emission order.

And a means for controlling to start light emission control for causing the plurality of light emitters to emit light one by one at a time difference when a pointing event is input by a user input.

  According to the present invention, since the light emission order can be grasped in advance, the light receiving points and the light emitters can be associated in time series according to the light reception order.

(7) The arrangement information detection system, game device, program, information storage medium, and arrangement information detection system control method of the present invention include:
The plurality of light emitters emit light in a predetermined order with a time difference for a predetermined period.

  For example, when applied to a game, a slight time difference may always be provided from the start of the game to the end of the game so that a plurality of light emitters emit light one by one in a predetermined order.

  In this way, there is less influence on the fixed predetermined surface than when light is emitted when there is a shooting event. Further, since the light is always emitted at a constant interval, a game environment that is not affected by shooting events of other players can be provided even when a plurality of players play a game on the same screen.

  In this embodiment mode, a plurality of light emitters are caused to emit light one by one with a slight time difference as shown in FIG. Since the system can grasp the light emission information related to the light emission timing, light emission history, light emission order, and light emission time of each light emitter, the light emitters corresponding to the light receiving points 2a, 2b, 2d, and 2c in FIG. It can be specified.

  For example, in the case 1, the information on the light emitters emitted at time t1 is acquired, and 2a, 2b, 2d, and 2c are 2A → 2B → 2D → based on the information on the light emission order of the plurality of light emitters held in advance. You may specify that it is a light-receiving point corresponding to 2C.

  In the case 2, since the order of light emission is known in advance by the system, the two light receiving points 2a, 2b, 2d, and 2c may be associated with the light emitters according to the light emission order in time series.

  In general, when multiple light emitters always emit light, the light receiving points and the light emitters are associated from the shape drawn by the detected light receiving points. In this case, however, the calculation algorithm becomes complicated and the calculation load is increased. Will also increase. Moreover, if the four light emitters 2A to 2D arranged in a rectangular shape always emit light, the position of the light emitter may not be associated with the detection position, for example, when rotated by 180 degrees.

  However, in this embodiment, it is possible to easily associate light receiving points and light emitters in a predetermined two-dimensional plane by emitting light with a slight time difference so as not to emit two or more light emitters at the same time. it can.

  In a state where a plurality of light emitters always emit light, it is difficult to detect the tilt and rotation of the shooting device unless the number of light emitters is four or more. This is because, when the pointing device is tilted, the polygonal shape specified by the detection position of the illuminant is deformed, so that it is difficult to associate.

  Further, when the pointing device is rotated at a predetermined angle, it is difficult to associate the polygonal shapes specified by the detection positions of the light emitters.

  FIGS. 5A and 5B and FIGS. 6A to 6E are diagrams for describing the case where two light emitters are configured in this embodiment.

  When detecting the arrangement of the pointing device with respect to the screen 1 using the two light emitters 2A and 2B, the two light emitters 2A and 2B are arranged near the two corners located on the diagonal line 250 on the outer periphery of the rectangular screen. The light is emitted one by one with a slight time difference, and the position is detected.

  In FIG. 5A, two light emitters 2A and 2B arranged near the two corners of the outer periphery of the rectangular screen emit light one by one in the order 2A → 2B with a slight time difference from time t1 → t2. Is shown.

  For example, a minimum time difference may be provided at all times for a predetermined period even if at least a light emitter is provided, and a plurality of light emitters may be caused to emit light one by one in a predetermined order (case 1), or when a shooting event occurs due to user input In addition, the plurality of light emitters may emit light one by one with a slight time difference (case 2).

  FIG. 5B shows the transition 2a → 2b of the light receiving point in a predetermined two-dimensional plane detected by the two-dimensional light position detector at time t1 → t2.

  In this embodiment mode, a plurality of light emitters are caused to emit light one by one with a slight time difference as shown in FIG. Since the system can grasp the light emission information regarding the light emission timing, light emission history, light emission order, and light emission time of each light emitter, it is possible to identify the light emitter corresponding to each light receiving point 2a, 2b in FIG. it can.

  For example, in case 1, the information on the light emitters emitted at time t1 is acquired, and 2a and 2b are light receiving points corresponding to 2A → 2B based on the information on the light emission order of a plurality of light emitters held in advance. May be specified.

  In case 2, the order of light emission is known in advance by the system, so that the light receiving points 2a and 2b may be associated with the light emitters in time series in accordance with the light emission order.

  In general, when two light emitters always emit light, the light receiving points are associated with the light emitters from the polygonal shape drawn by the detected light receiving points. For example, as shown in FIG. Thus, when two light receiving points 260 and 270 are detected, the case where the muzzle 280 is in the normal position as shown in FIG. 6B and the case where the muzzle 280 is in the normal position as shown in FIG. In this case, the case may be rotated 180 degrees.

  In the case of FIG. 6B, the correspondence between the light receiving point and the light emitter is as shown in FIG. 6D), and in the case of FIG. 6C, the correspondence between the light receiving point and the light emitter is shown in FIG. become that way.

  In this case, since the light emitter cannot be specified only by the light receiving point information, it cannot be specified whether the case is the case of FIG. 6B or the case of FIG.

  However, in the present embodiment, by causing a plurality of light emitters to emit light with a slight time difference so that two or more light emitters are not simultaneously emitted, the correspondence between a light receiving point and a light emitter in a predetermined two-dimensional plane even when there are two light emitters. Can be easily attached. Therefore, according to the present embodiment, the rotation of the pointing device can be detected even when there are two light emitters.

  Next, a method for obtaining the arrangement relationship of the shooting device with respect to the screen from the light receiving points on a predetermined two-dimensional plane of a plurality of light emitters will be described with reference to FIGS.

  FIGS. 7A to 7C are explanatory views showing changes in the light emitter detection position accompanying the parallel movement of the gun in the left-right direction with respect to the screen.

  FIG. 7A is a diagram showing the positional relationship between the screen and the light emitter, and FIG. 7B is a view of the muzzle GC-1 to GC-7 of the gun-type controller and the screen 1 as viewed from the Y-axis direction (XZ It is a figure showing the positional relationship (plan view) in a plane.

  FIG. 7C shows the transition of the detection position of the light emitter on the predetermined two-dimensional plane 20 corresponding to the transition of the muzzle position in the left-right direction of the gun-type controller.

  When the gun muzzle GC-1 to GC-7 move in the horizontal direction with respect to the screen 1 as shown in FIG. 7B, the positional relationship of the gun muzzle with respect to the light emitter also changes.

  Therefore, the detection positions 2a to 2d of the light emitters in a predetermined two-dimensional plane (virtual two-dimensional plane corresponding to the position of the two-dimensional optical position detection device) 20 are also 20-1 to 20-7 in FIG. It changes as follows. For example, when the gun muzzle is gradually translated in the right direction (see 30 in FIG. 7B), the detection positions 2a to 2d of the illuminant gradually move to the left in a predetermined two-dimensional plane (FIG. 7C 36)). Conversely, when the gun is translated leftward (see 32 in FIG. 7B), the detection positions 2a to 2d of the light emitter gradually move to the right within a predetermined two-dimensional plane (FIG. 7C). 38).

  FIGS. 8A to 8C are explanatory views showing changes in the light emitter detection position accompanying the parallel movement of the gun in the vertical direction with respect to the screen.

  FIG. 8A is a diagram showing the positional relationship between the screen and the light emitter, and FIG. 8B is a view of the muzzle GC-1 to GC-7 of the gun-type controller and the screen 1 from the X-axis direction (YZ It is a figure showing the positional relationship (side view) in a plane.

  FIG. 8C shows the transition of the detection position of the light emitter on the predetermined two-dimensional plane 20 corresponding to the transition of the muzzle position in the vertical direction of the gun-type controller.

  When the gun muzzles GC-1 to GC-7 move in the horizontal direction with respect to the screen 1 as shown in FIG. 8B, the positional relationship of the gun muzzle with respect to the light emitter also changes.

  For this reason, the detection positions 2a to 2d of the light emitters on a predetermined two-dimensional plane 20 (virtual two-dimensional plane corresponding to the position of the two-dimensional optical position detection device) 20 also change as shown in FIG. For example, when the gun muzzle is gradually translated downward (see 40 in FIG. 8B), the light emitter detection positions 2a to 2d gradually move upward in a predetermined two-dimensional plane (FIG. 8B 46)). Conversely, when the gun is translated upward (see 42 in FIG. 8B), the detection positions 2a to 2d of the light emitters gradually move downward in a predetermined two-dimensional plane (FIG. 8C 48)).

  As shown in FIGS. 7A to 7C and FIGS. 8A to 8C, when the gun muzzle is moved up, down, left and right within a plane arranged parallel to the screen, a predetermined two-dimensional Since the detection positions 2a to 2d of the illuminant on the plane 20 and the muzzle position of the gun-type controller (positions related to the XY axes) have a predetermined functional relationship, they are based on the detection positions 2a to 2d of the illuminant on the predetermined two-dimensional plane 20. The position of the gun muzzle (position with respect to the XY axes) can be specified.

  Therefore, a reference value corresponding to the detection value of the two-dimensional light position detection unit when the gun muzzle (pointing device) is in a predetermined arrangement state is stored in advance as reference value information, and the two-dimensional light position detection unit Based on the detected value and the reference value, the relative arrangement information of the gun muzzle (pointing device) and the screen may be calculated.

  Here, the reference value may be a voltage value or a current value output from the two-dimensional light position detector when in a predetermined arrangement state, or a light receiving point (light emitter) in a two-dimensional plane obtained from the voltage value or the current value. The coordinate value of (detection position) may be used.

  For example, by reading the vertical and horizontal displacements of the light receiving points 2a to 2d from the displacement of the coordinate value of the light receiving point (detection position of the light emitter) in the two-dimensional plane obtained from the voltage value and the current value, The amount of movement to the left and right can be detected.

  Here, the reference position is calculated by calculating the vertical and horizontal shifts of the light emitter detection positions 2a to 2d in, for example, a predetermined two-dimensional plane at the reference position, and based on the calculation result, the gun is moved vertically and horizontally. The amount may be detected.

  The reference position may be a predetermined position that hits the front with respect to the center of the screen.

  The detection positions 2a to 2d of the illuminant in a predetermined two-dimensional plane at the reference position may be set as default values, for example, or as an input for initial setting for each player prior to play, for example, with respect to the center of the screen You may set the detection position 2a-2d of a light-emitting body when shooting the center of a screen from the predetermined position which hits the front. In this way, subtle errors for each device can be absorbed.

  FIGS. 9A to 9C are explanatory diagrams showing changes in the light emitter detection position accompanying movement in the depth direction with respect to the screen.

  9A is a diagram showing the positional relationship between the screen and the light emitter, and FIG. 9B is a view of the muzzle GC-1 to GC-3 of the gun-type controller and the screen 1 from the X-axis direction (YZ It is a figure showing the positional relationship (side view) in a plane.

  FIG. 9C shows the transition of the detection position of the light emitter on the predetermined two-dimensional plane 20 corresponding to the transition of the muzzle position in the depth direction of the gun-type controller.

  As shown in FIG. 9B, when the gun muzzle GC-1 to GC-3 move in the depth direction with respect to the screen 1 (move in the direction perpendicular to the screen), the position of the gun muzzle with respect to the light emitter The relationship also changes.

  For this reason, the detection positions 2a to 2d of the light emitters on a predetermined two-dimensional plane 20 (virtual two-dimensional plane corresponding to the position of the two-dimensional optical position detection device) 20 also change as shown in FIG. For example, when the gun muzzle is gradually moved away from the screen 1 (see 60 in FIG. 9B), the rectangles having the vertexes at the four detection positions 2a to 2d of the illuminant are within a predetermined two-dimensional plane. The rectangle gradually becomes a similar rectangle (see 66 in FIG. 9C). On the other hand, when the gun muzzle is moved in the direction closer to the screen (see 42 in FIG. 9B), the rectangles having the vertexes of the four detection positions 2a to 2d of the light emitter are within a predetermined two-dimensional plane. It gradually becomes a rectangle with a larger similarity (see 68 in FIG. 9C).

  When moved in the depth direction with respect to the screen as shown in FIGS. 9A to 9C, the size of the rectangle having the vertexes at the four detection points 2a to 2d of the illuminant on the predetermined two-dimensional plane 20 is shown. Since the muzzle position (position with respect to the Z axis) of the gun-type controller has a predetermined functional relationship, the position of the gun muzzle (position with respect to the Z axis) can be specified based on the detection positions 2a to 2d of the light emitters. it can.

  FIGS. 10A to 10C are explanatory views showing changes in the light emitter detection position accompanying a change in direction in the left-right direction with respect to the screen.

  10A is a diagram showing the positional relationship between the screen and the light emitter, and FIG. 10B is a view of the muzzle GC-1 to GC-7 of the gun-type controller and the screen 1 viewed from the Y-axis direction (XZ It is a figure showing the positional relationship (plan view) in a plane.

  FIG. 10C shows the transition of the detection position of the light emitter on the predetermined two-dimensional plane 20 corresponding to the change in the direction of the muzzle of the gun-type controller in the left-right direction.

  When the orientation of the gun muzzle GC-1 to GC-7 with respect to the screen 1 changes in the left-right direction as shown in FIG. 10B, the arrangement relationship of the gun muzzle with respect to the light emitter also changes.

  For this reason, the detection positions 2a to 2d of the light emitters in a predetermined two-dimensional plane (virtual two-dimensional plane corresponding to the position of the two-dimensional optical position detection device) 20 also change as shown in FIG. For example, when the gun is tilted so that the tip of the gun gradually turns rightward with the gun placed directly in front of the screen 1 (see 70 in FIG. 10B), the detection positions 2a to 2d of the light emitters are predetermined two-dimensional planes. At the same time, the distance between the detection positions 2b and 2d on the right side gradually decreases (see 76 in FIG. 10C). When the tip of the gun is tilted gradually to the left (see 72 in FIG. 10B), the images 2a to 2d of the illuminant gradually move to the right within a predetermined two-dimensional plane, and at the same time the images on the left The interval between 2a and 2c is gradually narrowed (see 78 in FIG. 10C).

  FIGS. 11A to 11C are explanatory diagrams showing changes in the light emitter detection position accompanying a change in the vertical direction with respect to the screen.

  11A is a diagram showing the positional relationship between the screen and the light emitter, and FIG. 11B is a view of the muzzle GC-1 to GC-7 of the gun-type controller and the screen 1 viewed from the X-axis direction (YZ It is a figure showing the positional relationship (plan view) in a plane.

  FIG. 11C shows the transition of the detection position of the light emitter on the predetermined two-dimensional plane 20 corresponding to the change in the vertical direction of the muzzle of the gun-type controller.

  As shown in FIG. 11B, when the orientation of the gun muzzle GC-1 to GC-7 with respect to the screen 1 changes in the vertical direction, the arrangement relationship of the gun muzzle with respect to the light emitter also changes.

  For this reason, the detection positions 2a to 2d of the light emitters in a predetermined two-dimensional plane (virtual two-dimensional plane corresponding to the position of the two-dimensional optical position detection device) 20 also change as shown in FIG. For example, when the gun is tilted so that the tip of the gun gradually turns upward with the gun placed directly in front of the screen 1 (see 80 in FIG. 11B), the detection positions 2a to 2d of the light emitters are predetermined two-dimensional planes. At the same time, the distance between the upper detection positions 2a and 2b gradually decreases (see 86 in FIG. 11B). When the gun is tilted downward (see 82 in FIG. 11B), the detection positions 2a to 2d of the illuminant gradually move upward in a predetermined two-dimensional plane, and at the same time, the interval between the lower images 2c and 2d is increased. It becomes gradually narrower (see 88 in FIG. 11C).

  As shown in FIGS. 10A to 10C and FIGS. 11A to 11C, when moving in the vertical and horizontal directions with respect to the screen, the detection positions 2a to 2d of the light emitters in a predetermined two-dimensional plane 20 are shown. The shape and position of the quadrangle having the four points at the apex has a predetermined functional relationship with the inclination of the muzzle of the gun-type controller. Can be specified.

  12A to 12C are explanatory diagrams showing changes in the light emitter detection position accompanying changes in the rotation of the muzzle relative to the screen.

  FIG. 12A is a diagram showing an arrangement relation (plan view) of the screen, the light emitters 2A to 2D, and the muzzle of the gun-type controller GC as viewed from the Z-axis direction (in the YZ plane).

  FIG. 12B is a diagram showing rotation angles θ1 to θ5 with respect to the reference position K of the gun type controllers GC-1 to GC-5, and FIG. 12C is a rotation angle θ1 to θ5 of the muzzle of the gun type controller. The transition of the detection position of the light emitter in the predetermined two-dimensional plane 20 corresponding to the change of When the gun is gradually rotated clockwise about its axis with the gun's muzzle facing right in front of the screen 1 at right angles to the screen (90 in FIG. 12 (A), FIG. 12 (B) 94), the detection positions 2a to 2d of the light emitter rotate counterclockwise with respect to the outer frame within a predetermined two-dimensional plane (see 97 in FIG. 12C). On the other hand, when the gun is gradually rotated counterclockwise about its axis (see 92 in FIG. 12A and 96 in FIG. 12B), the detection positions 2a to 2d of the light emitters are predetermined two-dimensional. It rotates in the clockwise direction with respect to the outer frame in the plane (see 98 in FIG. 12C).

  When the gun muzzle is rotated with respect to the screen as shown in FIGS. 12A to 12C, the quadrangle having the four points of the light emitter detection positions 2a to 2d on the predetermined two-dimensional plane 20 as vertices is obtained. Since the two-dimensional plane 20 reversely rotates at the same angle with respect to the outer frame, the rotation of the gun muzzle (position with respect to the Z axis) can be specified based on the detection positions 2a to 2d of the light emitters.

  As described above, the positions of the detection positions 2a to 2d of the illuminant in the predetermined two-dimensional plane 20 change corresponding to the relative position, inclination, and rotation of the gun (two-dimensional optical position detection device) with respect to the screen 1. By performing a predetermined calculation based on the detection position, it is possible to detect the relative position, inclination, rotation amount, etc. of the gun with respect to the screen 1.

  FIG. 13 is a flowchart for explaining the processing flow of the present embodiment.

  If there is a trigger input from the gun-type controller, the following processing is performed (step S10).

  First, a light emitter (for example, an infrared light source) that emits light is specified (step S10). Next, the two-dimensional light position detection sensor senses light having a predetermined wavelength (for example, infrared light) (step S30).

  Next, a detection value (current value or voltage value) returned by the two-dimensional optical position detection sensor is measured (step S40).

  Next, a position on a predetermined two-dimensional plane (virtual coordinates in the two-dimensional optical position detection sensor) is determined based on the detection value (current value or voltage value) (step S50).

  The processes in steps S20 to S50 are repeated until the processes are completed for all the light emitters (step S60). That is, the processes in steps S20 to S50 are repeated for the number of light emitters, and the position of each light emitter on a predetermined two-dimensional plane (virtual coordinates in the two-dimensional light position detection sensor) is determined.

  Based on the obtained position data of all the light emitters, the placement information of the gun-type controller with respect to the screen is calculated (step S70).

  Then, a hit check calculation with the target of the game space is performed based on the arrangement information on the screen of the gun-type controller (step S80).
