Description

  The present invention relates to a technique for an operator to specify a position on a screen by moving an operating device.

  Japanese Laid-Open Patent Publication No. 11-305935 discloses a game device for a shooting game in which a player holds a simulated gun, moves the aiming position on the screen by changing the direction of the simulated gun, and performs virtual firing at the aiming position. Has been. As a method for detecting the aiming position of a shooting game, the first and second methods are widely known. In the first method, a light receiving element is provided in the muzzle of a simulated gun, and a display that scans the screen and displays an image is scanned with high brightness for a period of one screen (one frame period). This is a method of measuring the time from when the output level of the light receiving element becomes high until the time when the output level of the light receiving element becomes high, and specifying the aiming position based on the measured time. In the second method, a simulated gun is provided with a camera that captures an image in the same direction as the muzzle, a sign is placed near the screen, and the captured image is analyzed using the sign as a clue to aiming position It is a method to specify.

  In the game apparatus using the first method, it is necessary to frequently display an image (frame) in which the entire screen has high brightness, which makes the player feel annoying. Further, the first method has a drawback that the number of times the aiming position is detected per second does not exceed the frame rate. On the other hand, the game apparatus using the second method has the following drawbacks. Generally, in a shooting game, a large acceleration is often applied to a simulated gun. When a large acceleration is applied to the simulated gun, in the second method, problems such as blurring occur in the captured image. In other words, the second method has a drawback in that the accuracy of detecting the aiming position decreases as the acceleration of the simulated gun increases. The above-described drawbacks may occur not only when each method is applied to a game device, but also when the operator applies an arbitrary device that specifies a position on the screen by moving an operating machine such as a simulated gun.

  Therefore, the present invention provides an accuracy that does not depend on the acceleration applied to the operating device without causing the operator to feel visual inconvenience in any device in which the operator moves the operating device to specify the position on the screen. An image indicating the designated position is displayed at the designated position at a sufficiently short time interval.

Therefore, according to this image processing apparatus, it is possible to detect the position on the screen with a sufficiently short time interval with an accuracy that does not depend on the acceleration applied to the operating device, without causing the operator to feel visual inconvenience. . By the way, since it is the position, not the direction of the operating device, that is detected by the position detection unit, the normal position on the screen cannot be obtained by moving the operating device. Therefore, in this image processing apparatus, a straight line passing through the position detected by the position detection unit and a predetermined reference position is obtained, and an intersection position on the screen where the straight line intersects the screen is calculated, and the calculated intersection position is calculated. By displaying an image indicating an intersection, an image indicating the position is displayed at a specified position on the screen by moving the controller. Therefore, this image processing apparatus is an apparatus in which the operator moves the operating device to specify the position on the screen, and does not depend on the acceleration applied to the operating device without causing the operator to feel visual inconvenience. An image indicating the designated position can be displayed at the designated position with a sufficiently short time interval with accuracy.
The reference position may be a fixed position determined in advance or a dynamic position determined according to the operator. For example, if the operating device is held by the operator, the position between the shoulders of a general operator may be used as the reference position, or the position between the shoulders of each operator may be specified. The specified position may be used as the reference position.

  In the above image processing apparatus, the main body may further include a screen inside / outside determination unit that determines whether or not the straight line intersects the screen. According to the image processing apparatus of this aspect, since the screen inside / outside determination unit determines whether or not the straight line intersects with the screen, an image indicating the designated position is to be displayed at a position outside the screen.

In the game apparatus of this aspect, for example, the same operation machine is used for the action of causing the player's own character in the virtual space to shoot the enemy character with a shooting device such as a gun and the action of causing the enemy character to be beaten. In such a computer game, when the operating device is moved outside the screen on which the enemy character is displayed, the player's movement at this time is It can be determined that the movement is not an instruction to make the character move. For example, when a player plays a boxing game with one hand holding one operating device and the other hand holding another operating device, one arm remains in the guard state and the other arm Punching is often done, but if the player twists the body to punch with the other arm, one arm will also move, and it will be judged as if each arm is punching In the game device of this aspect, there is a possibility that such a determination is made using the fact that a straight line passing through the position of the controller and the reference position does not cross the screen in the guard state. Can be eliminated. As is clear from the above description, in the above game device, the game is a game in which the object displayed on the screen is shot with a shooting device, and the image indicating the intersection is a shooting device.

The play of the specific game starts when one or a plurality of predetermined coins having a value corresponding to the charge for one play of the specific game are inserted into the insertion slot 5 and then the start button 6 is pressed. . That is, the game apparatus 1 is a so-called arcade game machine.

  The display unit 12 has the screen 3 described above, and displays an image represented by the image data supplied from the processor 16 on the screen 3. Specifically, the display unit 12 is a display such as a CRT (Cathode Ray Tube). It is. Note that this embodiment may be modified so that a video projector is used instead of the display. The sound generation unit 13 is connected to the main body 100 and includes the speakers 4 and 4 described above. The sound generation unit 13 causes the speakers 4 and 4 to generate sound represented by the acoustic data supplied from the processor 16. That is, the display unit 12 and the sound generation unit 13 are output units that output information to the outside of the game apparatus 1.

  The operating device 8 is movable as described above. In addition, the operating device 8 can exchange signals with the main body 100. Furthermore, the operating device 8 is held by a player of a specific game, and can detect the physical motion of the player. Specifically, the operating devices 8AL and 8AR are held by being held by the player A, the operating devices 8BL and 8BR are held by being held by the player B, and each operating device 8 is held by its acceleration sensor 86. Thus, it is possible to detect the body motion of the player holding the operating device 8.

  The operating device 8 includes the grip unit 81, the operation buttons 82 and 83, the light emitting unit 84, the acceleration sensor 86, and the transmission unit 87. Each of the operation buttons 82 and 83 outputs a unique signal when pressed. The acceleration sensor 86 detects acceleration and outputs a signal indicating the detected acceleration (value).

That is, the operating device 8 functions as an operating device including an acceleration sensor that detects acceleration, a light emitting unit that emits light, and a transmission unit that transmits a value detected by the acceleration sensor to the main body side. Specifically, the light source 85 is an LED. The light emission frequency of the light source 85 is a frequency that does not interfere with external light, and is specifically about 170 KHz. This is because the external light in the game field hardly contains light having a frequency of about 170 KHz.

  The configuration of the controller 8 is determined so that the light emitted from the light emitting unit 84 can be easily received by the light receiving units 9L and 9R.

  The light receiving unit 9 has three infrared sensors. Each infrared sensor has a light receiving surface, can receive light emitted from the light source 85, and outputs a signal indicating the intensity of the received light. That is, the light receiving unit 9 functions as a light receiving unit that receives light emitted from the light emitting unit and detects the intensity of the received light. Among the above three infrared sensors, an infrared sensor having a light receiving surface perpendicular to the x axis is an x sensor 91, an infrared sensor having a light receiving surface perpendicular to the y axis is a y sensor 92, and a z axis. An infrared sensor having a simple light receiving surface is the z sensor 93. Signals output from these three infrared sensors are respectively supplied to the processor 16. Note that the three light receiving surfaces of the light receiving unit 9 are arranged so that perpendiculars passing through the center points of the respective light receiving surfaces intersect at one point. Hereinafter, this single point position is referred to as a “light receiving position”.

  FIG. 7 is a conceptual diagram for explaining a procedure for detecting the position of the controller 8. A rectangular parallelepiped space whose length in the x-axis direction is W, length in the y-axis direction is H, and length in the z-axis direction is D is a position detection range. The position detection range is a range in which the position of the operating device 8 can be detected in a specific game among the ranges in which the operating device 8 can move. The rectangular parallelepiped space is located in front of the screen 3, and one of the six surfaces includes the screen 3. The lengths of the upper and lower sides of the surface including the screen 3 are both W, and one end of the upper side is at the light receiving position PL of the light receiving unit 9L, and the other end is at the light receiving position PR of the light receiving unit 9R. In the present embodiment, the screen 3, the light receiving unit 9L, and the light receiving unit 9R are arranged so that W = H = 2m. In this embodiment, D = 2m, and the position detection range is a cubic space with a side of 2 m. The origin of the coordinate system of this space is at the light receiving position PL, and its coordinates are (0, 0, 0). In this coordinate system, the x coordinate increases toward the light receiving position PR, the y coordinate increases toward the floor of the game field, and the z coordinate increases as the distance from the screen 3 increases. The coordinates of the light receiving position PR of the light receiving unit 9R are (W, 0, 0).

  Here, as an example, a procedure for detecting the position of the light emission position PAL of the controller 8AL will be described. The “light emission position” is the position of the controller 8 that emits the light received by the light receiving units 9L and 9R. First, the light emitted from the controller 8AL is received by the light receiving units 9L and 9R. Then, three output signals are output from the light receiving unit 9L. Among these output signals, the output signals from the x sensor 91 and the y sensor 92 indicate weak received light intensity, and the output signal from the z sensor 93 indicates strong received light intensity. Therefore, the incident direction of light to the light receiving position PL can be specified based on these output signals. Similarly, the incident direction of light to the light receiving position PR can be specified based on the three output signals from the light receiving unit 9R. Therefore, the light emission position PAL can be obtained by the same principle as triangulation.

  FIG. 8 is a conceptual diagram for explaining the procedure for detecting the aiming position. As described above, the aiming position is determined for each operating device 8, and the aiming position of a certain operating device 8 is a straight line passing through the reference position of the player holding the operating device 8 and the position of the operating device 8. And the screen 3 position. The reference position of the player is the position of the midpoint of the line segment connecting both shoulders when the player faces the screen 3. Specifically, as shown in FIG. 8, the coordinates of the reference position PA of the player A are (W / 4, h, D), and the coordinates of the reference position PB of the player B are (3W / 4, h, D). ). h is a fixed value representing the height of the shoulder. It should be noted that the present embodiment may be modified so that the player can set h, or the game apparatus may automatically set h by measuring physical information such as the height and shoulder width of the player. Good.

Here, as an example, a procedure for detecting the aiming position PAAL of the controller 8AL will be described. First, in accordance with the procedures described, the light emitting position PAL operation unit 8AL (coordinates (x1, y 1, z1) ) obtained. Next, a straight line L1 passing through the obtained light emission position PAL and the reference position PA (coordinates are (W / 4, h, D)) of the player A holding the controller 8AL is obtained. Next, the aiming position PAAL (coordinates are (AALx, AALy, AALz)), which is the position of the intersection between the obtained straight line L1 and the screen 3, is obtained. Since the screen 3 and the light receiving unit 9L are both fixed and the positional relationship between the screen 3 and the light receiving unit 9L is known, the coordinates of the vertices that define the range of the screen 3 (for example, the vertex PS1 closest to the origin point) The coordinates (SX1, SY1, 0) and the coordinates (SX2, SY2, 0) of the diagonal vertex PS2 are also known.

  By the way, the type of the light source 85 is the same among the light emitting units 84. Therefore, when the plurality of light emitting units 84 emit light simultaneously, it becomes difficult to detect the light emitting position. Therefore, in the game apparatus 1, the light emission control signals supplied to the respective light emitting units 84 are made different so that the light sources 85 of the respective light emitting units 8 emit light when the light sources 85 of the other operating devices 8 are not emitting light. Yes. Specifically, the controller 8AL is supplied with a light emission control signal aAL, the controller 8AR is supplied with a light emission control signal aAR, the controller 8BL is supplied with a light emission control signal aBL, and the controller 8BR is supplied with a light emission control signal aBR. The The supply source of these light emission control signals is the processor 16. That is, the processor 16 causes the light emitting unit of each operating device to emit light when the light emitting units of other operating devices are not emitting light.

  FIG. 9 is a diagram for explaining the light emission control of the operating devices 8AL, 8AR, 8BL, and 8BR. As shown in this figure, in the play of a specific game, the position of the same controller 8 is periodically detected at a period T (for example, 16 ms). Then, when this period T is divided into four unit sections having a length of Δt, only the light emission control signal aAL in the first unit section, and only the light emission control signal aAR in the second unit section, Only the light emission control signal aBL is turned on in the unit section, and only the light emission control signal aBR is turned on in the fourth unit section. Therefore, in each cycle, only the controller 8AL is operated in the first unit section, only the controller 8AR is operated in the second unit section, only the controller 8BL is operated in the third unit section, and only the controller 8BL is operated in the fourth unit section. Only the machine 8BR emits light. That is, the operating devices 8AL, 8AR, 8BL and 8BR emit light in a time division manner.

  FIG. 10 is a diagram showing a memory map of the RAM 14. This memory map is for playing a specific game. The RAM 14 is a storage unit that stores a history of positions (positions of the operation devices 8 (light emission positions of the light emitting units 84)) detected by a position detection unit described later. An area MAL corresponding to 8AL, an area MAR corresponding to the operating device 8AR, an area MBL corresponding to the operating device 8BL, and an area MBR corresponding to the operating device 8BR are included.

  Each area includes an operation mode area in which data indicating the operation mode is held, a light emission position area in which data indicating the light emission position of the light emitting unit 84 is held, an aiming position area in which data indicating the aiming position is held, and a guard state And a trajectory buffer capable of holding a plurality of data indicating positions are secured. The operation modes include a punch mode for operating one hand of the player character who does not have a gun, and a shooting mode for operating one hand holding a gun. When data indicating the punch mode is written in the operation mode area, the operation mode is set to the punch mode. The light emitting position of the light emitting unit 84 is used as the position of the operating device 8 having the light emitting unit. The “guard” in the guard state is a guard in the sense of boxing. The trajectory buffer is used for punch detection, and holds data indicating a plurality of coordinates in the detection order as illustrated in the figure. In particular, the data stored at the head of the trajectory buffer indicates the position of the starting point (origin) of the punch trajectory. Hereinafter, this position is referred to as “punch origin position”.

  In FIG. 6 again, the ROM 15 stores the written data to store information indicated by the data, and stores a computer program P to be executed by the processor 16. When a power supply (not shown) is turned on, the processor 16 reads the computer program P from the ROM 15 and executes it. By this execution, the processor 16 performs a game process for causing the player to play the specific game.

<2. Operation>
FIG. 11 is a flowchart showing the flow of the game process. In the game process, the processor 16 first determines whether or not the play start condition is satisfied (SA1). Specifically, based on a signal from the storage unit 11 and a start signal from the start button 6, one or more coins having a value corresponding to the charge for one play of a specific game are inserted into the slot 5. It is determined whether or not the start button 6 has been pressed after being inserted. If this determination result is "NO", the process returns to Step SA1.

  If the determination result in step SA1 is “YES”, the processor 16 performs initialization prior to the start of play (SA2). Specifically, first, the operation mode is set to the punch mode. Secondly, one controller 8 (for example, controller 8AL) is set as a processing target. Third, a unit time timer is started. The unit time timer is a timer that times out when the time Δt elapses from the start, and is realized by the processor 16, for example.

  Next, the processor 16 performs a play process to advance the specific game using the display unit 12 (SA3). That is, the processor 16 functions as a game execution unit capable of progressing a specific game using the display unit 12. In the play process, the processor 16 performs the light emission control process for performing the light emission control shown in FIG. 9, the display process for generating and displaying the image, the operation process for the content according to the operation of the player, and the position of the operating device 8. The position detection process to be detected, the process of performing the attacked process every time an enemy character hits, and the process of repeatedly determining whether or not the play end condition is satisfied (step SA4: NO) are executed in parallel. To do. The operation process is executed for each controller 8. The attacked process is executed for each player. As will be described in detail later, in the position detection process, the processor 16 functions as a position detection unit that performs a process of detecting the position of the controller 8 based on the received light intensity detected by each of the light receiving units 9. The play process ends when the determination result in step SA4 is “YES”. The play end condition is satisfied when the remaining physical strengths of the players A and B become zero or less. Next, the processor 16 causes the display unit 12 to display the play result. The result of play is, for example, the number of defeated enemies. Thereafter, the process returns to step SA1.

  FIG. 12 is a flowchart showing the flow of display processing. In the display process, the processor 16 repeatedly executes a process of generating an image to be displayed on the display unit 12 (SB1) and a process of displaying the generated image on the display unit 12 (SB2). In the process of generating an image, a process of generating a projection image and a process of combining the generated projection image with another image are performed in order. Indicators IA and IB are always included as other images. The process of generating the projected image is performed after the player's character's fist is placed in the projected virtual space when the player performs a turning motion. In addition, the other images can include at least one of the aiming images AAL, AAR, ABL, and ABR. Specifically, among these aiming images, only those whose aiming position is within the screen 3 are included in the other images. Whether the aiming position is inside or outside the screen 3 is determined by the processor 16 based on the coordinates of the aiming position. Specifically, the processor 16 determines that the aim position is outside the screen 3 when the coordinates of the aim position stored in the aim position area of the RAM 14 are (0, 0, 0). In this case, it is determined that the aiming position is within the screen 3b.

  FIG. 13 is a flowchart showing the flow of operation processing. The operation process is executed in parallel for each controller 8. In the operation process, the processor 16 first determines whether or not a specific operation has been performed on the operation target machine 8 (SC1). If the determination result is “NO”, the process returns to Step SC1. If the determination result in step SC1 is “YES”, the subsequent processing differs depending on the specific operation performed.

  When the specific operation performed is pressing of the operation button 82, the processor 16 switches the operation mode of the controller 8 to be processed (SC2). Thereafter, the process returns to step SC1. When the specific operation performed is pressing of the operation button 83, the processor 16 determines whether or not the operation mode of the processing unit 8 to be processed is the shooting mode (SC3). Only when the determination result is “YES”, the processor 16 starts a firing process for causing the character to shoot a gun for the processing unit 8 to be processed (SC4). Thereafter, the process returns to step SC1.

  When the specific operation that is performed is an operation that causes the processing unit 8 to generate an acceleration toward the screen 3 that is equal to or greater than a predetermined reference value, the processor 16 sets the punch origin position ( SC5). Specifically, the trajectory buffer corresponding to the processing unit 8 to be processed is cleared, and the position stored in the light emission position area of the operating unit 8 when the acceleration occurs is added to the trajectory buffer. Adding a position to the trajectory buffer means adding data indicating the coordinates of the position to the trajectory buffer. However, the processor 16 stops the punch detection timer by stopping the punch detection timer in step SC5 if the punch detection timer for detecting punches is being timed for the processing unit 8 to be processed. After stopping the punch detection timer process corresponding to the timer, the position is added to the trajectory buffer. As will be described in detail later, the punch detection timer process is a process of starting the corresponding punch detection timer and clearing the corresponding locus buffer when the time measurement by the punch detection timer ends. Accordingly, the position added to the trajectory buffer in step SC5 is the punch origin position. Note that the punch detection timer is realized by the processor 16, for example. Next, the processor 16 starts punch detection timer processing (SC6). Thereafter, the process returns to step SC1.

  FIG. 14 and FIG. 15 are flowcharts showing the flow of the position detection process connected at the connection points α and β. In the position detection process, the processor 16 determines whether or not the unit time timer has timed out (SD1). The unit time timer is realized by the processor 16, for example. If this determination result is "NO", the process returns to step SD1. If the determination result in step SD1 is “YES”, the processor 16 starts a unit time timer (SD2).

  Next, the processor 16 detects and stores the position of the operation device to be processed (for example, the operation device 8AL) (SD3). Specifically, a total of three signals supplied from the x sensor 91, y sensor 92, and z sensor 93 of the light receiving unit 9L, and a total of the signals supplied from the x sensor 91, y sensor 92, and z sensor 93 of the light receiving unit 9R. Based on the three signals, the light emission position of the target operating device is detected, and the coordinates are written in the area of the RAM 14 corresponding to the operating device. In the following description, the operation device to be processed is referred to as a “target operation device”.

  Next, the processor 16 detects and stores the aiming position (SD4). Specifically, a straight line passing through the position detected in step SD3 and the reference position of the player holding the target operating machine is calculated, and an intersection position on the screen 3 where this straight line intersects with the screen 3 is calculated, and its coordinates Is written in the area of the RAM 14 corresponding to the operating device 8. In this way, the processor 16 functions as an intersection position calculation unit that calculates an intersection position on the screen where a straight line passing through the position of the controller detected by the position detection unit and a predetermined reference position intersects the screen. . This intersection position is the same as the above-mentioned aiming position. That is, the aiming image is also an image indicating that it is the intersection of the straight line and the screen. Further, as described above, in step SB2 of FIG. 12, the generated projection image and the aiming image whose aiming position is in the screen 3 are combined to generate an image to be displayed on the screen 3. This synthesis is performed so that the aiming image is displayed at the aiming position. Therefore, the processor 16 functions as a display control unit that controls the display unit so that an image indicating an intersection is displayed at the intersection position on the screen. In step SD4, when the straight line and the screen 3 do not intersect, the processor 16 sets the coordinates of the origin (0, 0, 0) as the coordinates of the aiming position and writes them in the aiming position area of the RAM 14. That is, the processor 16 functions as a screen inside / outside determination unit that determines whether or not a straight line intersects the screen. Further, as described above, considering that it is determined whether the aiming position is outside or inside the screen 3 depending on whether or not the coordinates of the aiming position are (0, 0, 0). The processor 16 functions as a storage control unit that stores the determination result of the screen inside / outside determination unit in the storage unit.

  Next, the processor 16 determines whether or not the arm of the player holding the target operating device is in a guard state (SD5). The determination result is “YES” when the position of the target operating device is within a predetermined range from the reference position of the player holding the operating device and the coordinates of the aiming position are (0, 0, 0). And “NO” in other cases. When the determination result is “YES”, the processor 16 sets a guard flag corresponding to the target operating device (SD6), and when it is “NO”, the processor 16 clears the guard flag (SD7).

  Next, the processor 16 determines whether or not the operation mode of the target operating device is the punch mode (SD8). When the determination result is “NO”, the processor 16 sets the next operating device 8 (for example, the operating device 8AR) as the target operating device (SD9). Conversely, if the determination result in step SD8 is “YES”, the processor 16 determines whether or not the punch detection timer corresponding to the target operating machine is counting time (SD10). If the determination result is “NO”, the process proceeds to step SD9.

  On the other hand, when the determination result of step SD10 is “YES”, the processor 16 adds the position of the target operating device to the trajectory buffer corresponding to the target operating device (SD11). Next, the processor 16 refers to the trajectory buffer corresponding to the target operating machine and determines whether or not a punch has been hit (SD12). At this time, the coordinate buffer indicating the trajectory of the target operating device from the punch origin is lined up in the trajectory buffer of the target operating device, and the determination result in step SD12 shows that this alignment satisfies a predetermined condition. “YES”, otherwise “NO”.

  Specifically, when the distance between the position in the trajectory buffer and the punch origin is set as the determination distance, the determination distance related to the latest position in the trajectory buffer is shorter than the determination distance related to the immediately preceding position. And when the determination distance which concerns on the said position immediately before is a predetermined reference distance (for example, 700 mm) or more, said determination result will be "YES". For example, in the example of FIG. 10, the latest coordinates (1410, 460, 980) in the trajectory buffer corresponding to the operating device 8AL are closer to the punch origin than the immediately preceding coordinates (1400, 460, 950), In addition, since the distance between the immediately preceding coordinate (1400, 460, 950) and the punch origin is 700 mm or more, the above determination result is “YES” when the reference distance is 700 mm.

  In this manner, the processor 16 functions as an operation determination unit that determines whether or not the operator has performed a turning operation from the position history of the operating device and the detection value of the acceleration sensor. The operation determination unit uses the position of the position detected by the position detection unit immediately before the acceleration sensor detects an acceleration equal to or higher than a predetermined reference value as the origin, and the position detected by the position detection unit after the origin detection. The first determination distance related to the first position detected by the position detection unit at a certain point in time with the distance from the origin as the determination distance, and the second determination related to the second position detected by the position detection unit immediately before From the relationship with the determination distance, it is determined whether or not a turning operation has been performed. Further, the motion determination unit is configured such that the first determination distance related to the first position is shorter than the second determination distance related to the second position, and the second determination distance related to the second position is When the distance exceeds a predetermined reference distance, it is determined that the turning operation has been performed.

  However, in step SD12, the processor 16 does not determine that the punch has been hit and the punch has been hit when the coordinates of the aim position stored in the aim position area of the RAM 14 are (0, 0, 0). Judge that there was no. That is, if the determination result stored in the storage unit is negative as the operation determination unit, the processor 16 determines that the operator has not performed a predetermined operation. Thereby, for example, when the player performs an operation of turning the controller 8 out of the screen 3 in an attempt to guard, a situation in which this operation is erroneously detected as a punch can be avoided.

  If the determination result of step SD12 is “NO”, the process proceeds to step SD9. On the other hand, if the determination result is “YES”, the processor 16 starts punching processing for punching the character (SD13). Thereafter, the process proceeds to step SD9. When step SD9 ends, the process returns to step SD1. As described above, the processor 16 cyclically repeats the above-described processing for the operating devices 8AL, 8AR, 8BL, and 8BR as a position detection unit.

  FIG. 16 is a flowchart showing the flow of the firing process. In the firing process, the processor 16 determines whether or not the bullet fired by the operation of the corresponding controller 8 hits the enemy character (SE1). Specifically, it is determined whether or not a straight line passing through the position of the corresponding controller 8 and the aiming position intersects the enemy character in the virtual space. That is, the processor 16 advances a specific game based on the intersection position on the screen 3 and the signal from the operating device 8 as a game execution unit. This determination method is arbitrary. For example, the area occupied by the enemy character on the screen 3 may be obtained, and it may be determined whether or not the straight line passes through the area, or the straight line is extended into the virtual space, and the straight line is You may make it determine whether it crosses with a character. When the determination result is “YES”, the processor 16 performs a bullet hit process (SE2).

  Specifically, the enemy character (the enemy character E3 in FIG. 5) hit by the bullet and the location of the hit are identified, and the enemy character is damaged according to the identification result to reduce the remaining physical strength of the enemy character. The effect processing according to the specific result is performed using the display unit 12 and the sound generation unit 13. For example, in the example of FIG. 5, the firing sound is generated from the speakers 4 and 4, and an image in which the enemy character E3 hitting the left hand is damaged and the gun is removed from the left hand is displayed. On the other hand, when the determination result of step SE1 is “NO”, the processor 16 performs a bullet removal process (SE3). Specifically, the sound generation unit 13 is caused to generate a firing sound. When the process of step SE2 or SE3 ends, the firing process ends.

  FIG. 17 is a flowchart showing the flow of the punch detection timer process. The punch detection timer process is executed every time an acceleration toward the screen 3 that is equal to or greater than the reference value occurs for each operating device 8. In a punch detection timer process, the processor 16 first starts a punch detection timer corresponding to the punch detection timer process (SF1). Next, the processor 16 determines whether or not the punch detection timer is counting time (SF2). If the determination result is “YES”, the process returns to step SF2. On the other hand, if the determination result of step SF2 is “NO”, the processor 16 clears the trajectory buffer corresponding to the punch detection timer process (SF3), and ends the punch detection timer process.

  FIG. 18 is a flowchart showing the flow of punch processing. The punching process is a process performed when it is determined in step SD12 in FIG. 15 that a punch has been hit. In the punching process, the processor 16 first stops the punch detection timer for the target operating device (SG1). Next, the processor 16 specifies the punch direction, the arrival point, and the type (SG2). Specifically, referring to the trajectory buffer corresponding to the target operating device, the point farthest from the punch origin is the arrival point, and the direction of the straight line passing through this arrival point and the punch origin is the punch direction. If this direction is within the first direction range starting from the punch origin, then “hook”; if the direction is within the second direction range starting from the punch origin, “upper cut”; If it does not fall in any direction range, it will be “straight”. Note that the first and second direction ranges are determined in advance.

  As described above, the processor 16 is a type specifying unit that specifies the type of the turning operation from the subsequent position history from the origin when the operation determining unit determines that the turning operation has been performed. 16 is a turning operation based on this direction and a predetermined direction range when the position farthest from the origin is the arrival point and the direction of the straight line passing through the arrival point and the origin is the direction of the turning operation. It functions as a type specifying unit that specifies the type of the. Further, the processor 16 functions as a direction calculating unit that calculates the direction of a straight line passing through the origin and the second position when the operation determining unit determines that the turning operation has been performed.

  Next, the processor 16 clears the trajectory buffer corresponding to the target operating device (SG3). The subsequent processing differs depending on the identified punch type. If the identified punch type is a hook, the processor 16 determines whether or not this hook hits an enemy character (SG4). Specifically, it is determined whether or not the fist trajectory determined based on the direction, reaching point, and type specified in step SG2 intersects with the enemy character in the virtual space. If this determination result is "YES", the processor 16 performs hook hit processing (SG5).

  Specifically, an enemy character (the enemy character E1 in FIG. 4) hit by the hook and a hit location are specified, and the enemy character is damaged according to the specified result to reduce the remaining physical strength of the enemy character. On the other hand, an effect process according to the specific result is performed using the display unit 12 and the sound generation unit 13. For example, in the example of FIG. 4, a sound effect indicating that the punch has hit is generated from the speakers 4 and 4, and the fist FAR of the right hook moves in the virtual space and hits the enemy character E 1. An image is displayed in which E1 is damaged and loses posture. On the other hand, when the determination result of step SG4 is “NO”, the processor 16 performs a hook removal process (SG6). Specifically, the display unit 12 displays an image of the right hook fist FAR moving in the virtual space. When the process of step SG5 or SG6 ends, the punching process ends.

  When the identified punch type is an upper cut, the processor 16 determines whether or not this upper cut hits an enemy character (SG7). If this determination result is "YES", the processor 16 performs an upper cut hit process (SG8). Specifically, the enemy character (the enemy character E1 in FIG. 5) and the hit location hit by the upper cut are specified, and the enemy character is damaged according to the specified result to reduce the remaining physical strength of the enemy character. On the other hand, an effect process according to the specific result is performed using the display unit 12 and the sound generation unit 13. For example, in the example of FIG. 5, a sound effect indicating that the punch has hit is sounded from the speakers 4 and 4, and the left upper-cut fist FAL moves in the virtual space and hits the enemy character E 1. An image is displayed in which the character E1 is damaged and loses his posture. On the other hand, when the determination result of step SG7 is “NO”, the processor 16 performs an upper cut removal process (SG9). Specifically, the display unit 12 displays an image in which the left upper-cut fist FAL moves in the virtual space. When the process of step SG8 or SG9 ends, the punching process ends.

  When the identified punch type is straight, the processor 16 performs the processes of steps SG10 and SG11 or steps SG10 and SG12. Since these processes are clear from the above description regarding the hook and the upper cut, the description thereof will be omitted.

  FIG. 19 is a diagram illustrating the flow of the attacked process. The attacked process is executed when an attack from an enemy character hits the player character. In the attacked process, the processor 16 specifies a guard flag corresponding to the character hit and the type of attack hit (SH1). For example, if the attack hit is a punch to the left half of the character of the player A, a guard flag corresponding to the operating device 8AL is specified.

  Next, the processor 16 determines whether or not the identified guard flag is set (SH2). When this determination result is “NO”, that is, when the effective guard is not performed, the processor 16 sets normal damage to the hit character and reduces its remaining physical strength (SH3). On the other hand, when the determination result in step SH2 is “YES”, that is, when effective guarding is performed, the processor 16 sets mitigation damage to the hit character and reduces its remaining physical strength (SH4). Normal damage is damage that is taken when effective guard is not performed, mitigation damage is damage that is received when effective guard is performed, and mitigation damage is lighter than normal damage. Therefore, the amount of decrease in the remaining physical strength is small when the mitigation damage is set, and increases when the normal damage is set. When the process of step SH3 or SH4 ends, the attacked process ends.

  As is clear from the above description, the game apparatus 1 includes an operation determination device (not shown) for determining whether or not a turning operation has been performed, a display unit 12 connected to the fixed main body 100, and the main body 100. It is grasped | ascertained as a game device which has the game execution part (processor 16) which is provided and can advance a specific game using the display part 12. FIG. The game execution unit is configured to execute predetermined instructions (various hit processes or various missed processes) when it is determined by the motion determination unit that the hitting operation has been performed. The motion determination device includes a main body 100 and a movable controller 8 that is held by the player, detects the physical motion, and can exchange signals with the main body 100. The operating device 8 includes an acceleration sensor 86 that detects acceleration, a light source 85 that emits light, and a transmission unit 87 that transmits a value detected by the acceleration sensor 86 to the main body 100 side. The light receiving units 9L and 9R disposed at two locations for receiving the light emitted from the light 85 and detecting the light receiving intensity, and the position of the controller 8 based on the light receiving intensity detected in each of the light receiving units 9L and 9R A position detection unit (processor 16) that repeatedly performs the process of detecting the position, a RAM 14 that stores a position history of the operating device 8 detected by the position detection unit, a position history of the operating device 8, and a detected value of the acceleration sensor 86. And a motion determination unit (processor 16) for determining whether or not the player has performed a scolding motion. Therefore, the game device 1 is a device that should perform processing according to the motion when the player performs a predetermined motion, and determines whether or not the player has performed a scolding motion. Accordingly, processing corresponding to the turning operation can be performed. In this example, the turning operation is determined by the processor 16, but a predetermined operation may be determined.

  Further, acceleration generated when a predetermined motion is performed and information (for example, movement distance) obtained from the position of the operating device 8 are stored in the ROM 15 as motion patterns, and the processor 16 actually matches the motion patterns. The detected acceleration may be compared with information obtained from the position to determine whether or not a predetermined operation has been performed. Thereby, for example, an operation of quickly swinging the operating device 8 with a small amplitude (a large acceleration and a small moving distance) or an operation of slowly swinging the operating device 8 with a large amplitude (a small acceleration and a large moving distance). It becomes possible to discriminate.

  In addition, when an acceleration equal to or higher than a predetermined reference value is detected by the acceleration sensor, the processor 16 performs a predetermined operation by referring to the position history stored in the RAM 14 using this as a trigger. It may be determined whether or not. In this aspect, since the determination of the predetermined motion is performed only when the player moves the operating device 8 with an acceleration equal to or higher than the reference value, it is not necessary to always perform the motion determination, thereby reducing the processing load. it can. In addition, one of the predetermined motion conditions is that the player's arm is moved at an acceleration equal to or higher than the reference value. Even if the player is conscious not to move the arm, the player moves slightly. When an instruction is input by a predetermined action, a delicate action does not reflect the player's intention and needs to be eliminated. In this aspect, since it is possible to set one of the predetermined motion conditions that the acceleration equal to or higher than the reference value is detected, it is possible to input an instruction accurately.

  Further, as described above, the game apparatus 1 is provided in an image processing apparatus (not shown) that displays an image indicating the designated position at a position designated by the player, and the fixed main body 100. The display device 12 is used as a game device having a game execution unit (processor 16) capable of progressing a specific game. The image processing apparatus includes a main body 100, a light source 85 that emits light, a movable operation device 8 that is held by a player, a screen 3, and a fixed display unit 12. The main body 100 receives light emitted from the light source 85 of the operating device 8 and detects the received light intensity, and includes at least two light receiving units, the light receiving units 9L and 9R, and the light receiving units 9L and 9R. A position detection unit (processor 16) that repeatedly performs the process of detecting the position of the operating device 8 based on the received light intensity, and the position of the operating device 8 detected by the position detecting unit and a predetermined reference An intersection position calculation unit (processor 16) for calculating an intersection position on the screen 3 where a straight line passing through the position intersects with the screen 3, and an image indicating that it is an intersection is displayed at the intersection position on the screen 3 A display control unit (processor 16) for controlling the unit 12. The operating device 8 can detect a player's body movement and can exchange signals with the main body 100, and the game execution unit can play a specific game based on the intersection position on the screen 3 and a signal from the operating device 8. Make it progress. Therefore, the game apparatus 1 is an apparatus in which the player moves the operating device 8 to specify a position on the screen 3, and does not depend on the acceleration applied to the operating device 8 without causing the player to feel visual inconvenience. An image indicating the designated position (intersection point) can be displayed at the designated position (intersection position) with a sufficiently short time interval with accuracy.

<3. Modification>
The present invention is not limited to the above-described embodiment, and may include modifications listed below.
In the above-described embodiment, the player can select the use / nonuse of the gun as appropriate, but this may be modified. For example, the specific game may be a computer game having a plurality of stages, and the use of a gun may be prohibited in a certain stage and the use of a punch may be prohibited in another stage.
