Abstract

PROBLEM TO BE SOLVED: To certainly discriminate an abnormal state if a gun-type controller is in the abnormal state impossible to normally detect a point appearing in a picture on a display. SOLUTION: In a light receiving sensor 11 in the gun-type controller 6 receives a raster point at the point of coordinates (X, Y), the coordinates position (X, Y) is operated by a position arithmetic circuit 13 based on the light receiving signal, and the position information is transmitted to the CPU 17 of a control unit 8. The position arithmetic circuit 13, if the light receiving sensor 11 receives a continuous light which is not a raster point or if a light is not received continuously in a scanning period for one frame, operates and outputs a trouble information signal instead of the position information (X, Y). That the controller 6 is in an abnormal state impossible to direct a position in the picture 7a is discriminated by this trouble information signal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position indicating device for indicating a position on a screen of a video display device such as a CRT display. The invention also relates to a shooting simulation device using such a position pointing device.

[0002]

2. Description of the Related Art Heretofore, there has been known a shooting simulation device including a video display device such as a CRT display and a controller formed by imitating a gun.
In this shooting simulation device, an appropriate image including a target is projected on a screen of an image display device, and a player holding a gun-type controller operates a trigger lever of the gun-type controller aiming at the target image. When the player operates the trigger lever, if the position on the screen that the gun-type controller is aiming for matches the position where the target image is projected on the screen, it is determined that the target has been shot down by the gun Then, arithmetic processing corresponding to the successful shooting is performed. On the other hand, when the trigger lever is operated, if the position in the screen targeted by the gun-type controller does not match the position where the target image is projected in the screen, it is determined that the shooting has failed. The arithmetic processing corresponding to the shooting failure is performed.

In the shooting simulation device, in order to perform the above-described processing, it is necessary to detect which position in the screen of the video display device the gun-type controller indicates. As a device for performing such position detection processing, the following device has been conventionally known. That is, as shown in FIG.
An appropriate image is displayed on the screen 7a of the T display 7,
The player having the gun-type controller 6 plays while standing in front of the screen 7a. The gun type controller 6 is provided with a light receiving sensor and a position calculation circuit in advance. CRT
When the electron beam scans and moves within the screen to display an image on the screen of the display 7, if a bright spot of the electron beam is detected by the light receiving sensor, the coordinates of the detected bright spot in the display screen are displayed. The position is calculated by the position calculation circuit.

[0004]

However, the conventional position pointing method has the following problems. That is, when the gun-type controller 6 faces the wall 3 around the display 7 as shown in FIG. 5B, or when the gun-type controller 6 faces the fluorescent lamp 4 as shown in FIG.
When facing the light bulb 5 as in (D), or facing sunlight as in (E), it is not possible to indicate the desired position on the screen 7a of the display 7 as a matter of course. , It was not clear which direction the gun-type controller 6 was pointed. In this case, a normal simulation operation cannot be performed.

[0005] When the controller 6 is directed to the screen of the display 7, but the fluorescent lamp 4, the light bulb 5 or the sunlight is present near the display 7, the controller 6 has a relatively strong continuous light. Therefore, a bright spot for which raster scanning is being performed cannot be detected, and thus, a normal position indication cannot be performed in this case. In addition, when the light receiving sensor has a failure and does not output a normal signal, conventionally, the player cannot know the fact, and thus may not be able to perform a normal simulation. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been described in which a position pointing device such as a gun-type controller cannot normally detect a bright spot appearing on a screen of a video display device such as a CRT display. An object of the present invention is to make it possible to reliably determine an abnormal state when the apparatus is in a state.

[0007]

The position calculating means outputs a position information signal of the bright spot based on a signal indicating that the light receiving sensor has received the bright spot, and the light receiving sensor does not receive light during at least one frame scanning period. A failure information signal is output based on the signal indicating

The first position pointing device and the second position pointing device are different from each other in that the light receiving sensor receives continuous light and that the light receiving sensor does not receive light. According to each of these position pointing devices, when an abnormal state in which a bright spot appearing in the screen of the video display device cannot be normally detected, a fault information signal is output from the position calculating means,
The abnormal state can be reliably detected. For example, when the position indicator faces a dark place other than the image display device, or when the position indicator receives continuous light from a place other than the image display, this can be easily determined. Further, even when the light receiving sensor cannot output a normal signal due to a failure, it can be easily determined.

Next, as one embodiment of the first position pointing device, the position calculating means is operated as follows, ie, when the light receiving sensor receives continuous light within the vertical blanking period, predetermined fault information is obtained. A signal can be generated and the fault information signal can be continued when the light receiving sensor receives continuous light even during a scanning period following the vertical blanking period.

Next, as one embodiment of the second position indicating device, the position calculating means is operated as follows, that is, when the light receiving sensor does not receive light within the vertical blanking period, predetermined fault information is obtained. A signal may be generated, and the fault information signal may be continued even when the light receiving sensor does not receive light even during a scanning period following the vertical blanking period.

Next, in the first and second position pointing devices, the video display device may be, for example, a raster scanning type video display device. The above-mentioned fault information signal can be generated by a dedicated signal generation circuit, but is preferably formed by assigning a specific value to the coordinate position information signal. In this case, as long as a circuit configuration for generating the coordinate position information signal is prepared, no other special circuit is required. Further, various measures can be considered as to what to do when the above-described trouble information signal is output. For example, a display for calling attention to the player is displayed on the screen of the video display device. be able to.

Next, a first shooting simulation apparatus according to the present invention comprises: a video display device for displaying a video; a position specifying means for specifying a position in a screen of the video display device; And a control unit for controlling an image displayed on the image display device based on the output information of the shooting simulation device. The image display device displays an image in the screen by visually combining the bright spots in the screen. The position indicating means has a position indicator directed to a position in the screen, a light receiving sensor disposed on the position indicating body, and a position calculating means for performing an arithmetic process by receiving an output signal of the light receiving sensor. . And
The position calculating means outputs a position information signal of the bright spot based on a signal indicating that the light receiving sensor has received a bright point, and a failure information signal based on a signal indicating that the light receiving sensor has received continuous light. Is output.

[0014] A second shooting simulation apparatus according to the present invention comprises: a video display device for displaying a video; a position specifying means for specifying a position in a screen of the video display device; Control means for controlling an image displayed on the image display device based on output information. The image display device displays an image in the screen by visually combining the bright spots in the screen. The position indicating means has a position indicator directed to a position in the screen, a light receiving sensor disposed on the position indicating body, and a position calculating means for performing an arithmetic process by receiving an output signal of the light receiving sensor. . And
The position calculating means outputs a position information signal of the bright spot based on a signal indicating that the light receiving sensor has received the bright spot, and a signal indicating that the light receiving sensor does not receive light during at least one frame scanning period. And outputs a fault information signal based on.

The difference between the first and second shooting simulation apparatuses is that the light receiving sensor of the first shooting simulation apparatus receives continuous light with respect to the position indicating means. Thus, in the second shooting simulation device, the light receiving sensor does not continuously receive light, that is, the non-light state continues. According to each of these shooting simulation devices,
When the position indicator is in an abnormal state in which the luminescent spot that scans and moves on the screen of the video display device cannot be normally detected, a fault information signal is output from the position calculation means, so that the abnormal state can be reliably determined. For example, when the position indicator faces a dark place other than the image display device, or when the position indicator receives continuous light from a place other than the image display, this can be easily determined. Further, even when the light receiving sensor cannot output a normal signal due to a failure, it can be easily determined.

In each of the above-described shooting simulation apparatuses, the position support can be formed in the shape of a gun.

[0017]

And a position calculation circuit 13 connected to one output terminal. The casing 9 has an appearance simulating a gun, and includes a grip portion 9a for a player to grip with a hand. The grip 9a is provided with a trigger lever 14 corresponding to a trigger of a gun, and a trigger switch 16 is connected to the trigger lever 14.

The above-mentioned control device 8 is a CPU (central processing unit) 17 for controlling the entire shooting simulation device.
And a video control circuit 18 for driving the CRT display 7. The CPU 17 is provided with a ROM 19 storing program software for realizing the operation of the shooting simulation, and a RAM 21 used as a work area when performing various calculations performed by the CPU 17. The gun-shaped casing 9 is connected to the control device 8 via a flexible cable 22. The video control circuit 18 transmits an image signal to the position calculation circuit 13 through the flexible cable 22. This image signal includes the same signal as the image signal transmitted to the CRT display 7. The output signals of the position calculation circuit 13 and the trigger switch 16 are transmitted to the input port of the CPU 17 through the flexible cable 22. The position calculation circuit 13 can be provided inside the control device 8 instead of inside the gun-shaped casing 9.

As shown in FIG. 2, the position calculation circuit 13

Subsequent to the counting control unit 26, there are provided respective counting units of an X coordinate counting unit 27, a first Y coordinate counting unit 28, and a second Y coordinate counting unit 29. Also,
An X coordinate register 31 is provided downstream of the X coordinate counting section 27. An averaging circuit 32 and a Y coordinate register 33 are provided downstream of the first Y coordinate counting section 28 and the second Y coordinate counting section 29.

As shown in FIG. 3, the counting control unit 26 of the above circuits includes an OR circuit 34 for receiving a light receiving signal,
An AND circuit 36 provided at a subsequent stage, a second raster extraction circuit 37 for receiving a light receiving signal, and a gate circuit 3
8 is provided.

Each of the coordinate counting units 27, 28, 2
9 includes a counter 39 and a latch circuit 41 as shown in FIG. In the X coordinate counting section 27, a clock signal for counting is input to a clock terminal of the counter 39, and a horizontal synchronization signal HS is input to a clear terminal. First Y coordinate counting unit 2
8 and the second Y coordinate counting unit 29, the counter 39
, A horizontal synchronizing signal HS enters the clear terminal and a vertical synchronizing signal VS enters the clear terminal. Further, an S signal or an E signal, which is an output signal of the count control unit 26, is transmitted to the trigger terminal of the latch circuit 41.

Hereinafter, the operation of the shooting simulation device having the above configuration will be described. When the simulation is started, the image information is transmitted to the image control circuit 18 by the CPU 17 in FIG. 1, and the electron beam is horizontally and vertically scanned on the screen 7a of the CRT display 7 based on the image information to form a raster. Forming
This raster shines according to the brightness of each pixel,
The image is displayed. This image includes a target to be fired. The above video information is transmitted to the position calculation circuit 1
3 includes the same signal as the image signal transmitted to the third signal.

A player standing in front of the display 7 while holding the casing 9 of the gun type controller 6 in his hand turns the tip of the gun type casing 9 toward the screen 7a while watching the image projected on the screen 7a of the display 7. . The position in the screen 7a to which the gun-type controller 6 faces is XY where the horizontal direction of the screen is the X coordinate and the vertical direction is the Y coordinate.
Can be displayed as coordinate values.

The mutual positional relationship between the gun-type controller 6 and the display 7 is as follows: (1) When the gun-type controller 6 normally faces the screen 7a of the display 7 as shown in FIG. When the gun type controller 6 faces a dark place other than the display 7 as shown in FIG.
(3) As shown in FIGS. 5 (C) to 5 (E), when the gun-type controller 6 faces a bright place other than the display 7 and continuous light enters it, or the gun-type controller 6 faces the screen 7a. However, there may be a case where a light source such as a fluorescent lamp is placed near the screen and continuous light enters the controller 6. Hereinafter, individual cases will be considered.

(1) When the gun-type controller normally faces the screen of the display The gun-type controller 6 normally turns the screen 7a of the display 7
, At least one raster luminescent spot is always received by the light receiving sensor 11 in the controller 6 every scanning period of one frame. And in this case, FIG.
In, an image signal is transmitted from the video control circuit 18 of the control device 8 to the position calculation circuit 13 of the gun-type controller 6. This image signal is separated into a horizontal synchronizing signal HS and a vertical synchronizing signal VS by the sync separation section 23 in FIG. Then, as shown in FIG. 6, the timing generation section 24 calculates a vertical blanking period based on the horizontal synchronization signal HS and the vertical synchronization signal VS.

Further, as shown in FIG. 7, the timing generation section 24 sets the
A reset A signal and a reset B signal, which are two kinds of signals, are generated based on the horizontal synchronization signal HS and the vertical synchronization signal VS. If you are thinking now, that is, if the gun-type controller 6 normally faces the screen 7a of the display 7,
The S signal and the E signal generated in the vertical blanking period as described above have no special meaning. These signals are meaningful at the time of abnormality such as when light from a raster bright point does not enter the gun-type controller 6 or when continuous light other than the raster bright point enters.
Details will be described later.

In the scanning period of one frame following the vertical blanking period, the raster luminescent spot scans the screen 7a horizontally and vertically. When the raster luminescent spot passes through the position designated by the gun-type controller 6, the luminescent spot is detected by the light receiving sensor 11 in the controller 6, and as shown in FIG. Occur. These light receiving signals “0” are sent to the count control unit 26 in FIG.

As shown in FIG. 6, the counting controller 26 converts the received light receiving signal "0" into an S signal and an E signal. The E signal is a signal obtained by sampling the light receiving signal, and is substantially the same as the source signal. On the other hand, the S signal is a signal obtained by further processing the E signal to transmit the light until the next raster timing of the raster in which the light reception signal indicates light reception. Such processing is realized by the circuit configuration shown in FIG. By the above processing, the rising edge of the S signal indicates the start point of light reception, and the last rising edge of the E signal indicates the end point of light reception.

As described above, the counting control unit 26 executes S
When the signal and the E signal are generated, in FIG. 2, based on the S signal and the E signal, the X coordinate counting unit 27, the first Y coordinate counting unit 28, and the second Y coordinate counting unit 29 determine the raster luminescent point. The coordinate position, that is, the position indicated by the gun type controller 6 is calculated.

More specifically, the X coordinate counting section 27
In FIG. 8, the HS signal is used as a counting start signal, the S signal is used as a counting stop signal, and the counting clock signal is counted. As a result, the X coordinate value which is the horizontal light receiving start position of the CRT display 7 is calculated. Count. The figure illustrates a state where “9” is counted as the coordinate value. The above processing is realized by the circuit configuration shown in FIG.

On the other hand, the first Y coordinate counting section 28 in FIG. 2 counts the HS signal in FIG. 9 with the VS signal as the counting start signal and the S signal as the counting stop signal. Also,
The second Y coordinate counting section 29 counts the HS signal using the VS signal as a count start signal and the E signal as a count stop signal. The average value of the count values of the first Y coordinate counting unit 28 and the second Y coordinate counting unit 29 is calculated by using the averaging circuit 32 of FIG. 2 to determine the light receiving center position of the CRT display 7 in the vertical direction. A Y coordinate value is determined. The above processing is also realized by the circuit configuration shown in FIG.

As described above, the position specified by the gun-type controller 6 is specified by the (X, Y) coordinate value. These coordinate data are respectively stored in the X coordinate register 31 and the Y coordinate register 33 of FIG.
The position information (X, Y) thus stored is output to the control device 8 (FIG. 1) at an appropriate timing, for example, at an appropriate timing in a vertical blanking period following the scanning period. Further, if the player operates the trigger lever 14 of the gun-type controller 6 in the direction of the arrow A during the scan period being considered, the position calculation circuit 13 outputs the position information (X, Y). , And outputs a trigger signal, which is a signal indicating that the trigger lever 14 is pulled, to the control device 8. These signals can be transmitted in the form of, for example, 6 bytes of serial data. For example, appropriate bits in the first 2 bytes of the 6 bytes are assigned to a trigger signal, and the next 2 bytes are assigned to an X coordinate value. , And the last two bytes can be assigned to the Y coordinate value.

In FIG. 1, the CPU 17 in the control device 8 having received the position information (X, Y) and the trigger signal,
According to the program stored in the OM 19, it is determined whether or not the timing at which the trigger signal is generated matches the coordinate position (X, Y). When they match, an operation for displaying a successful shooting is performed, and when they do not match, an operation for displaying a shooting failure is performed. Thus, the simulation of the shooting operation is executed.

(2) When the gun-type controller faces a dark place other than the display, as shown in FIG. 5B, when the gun-type controller 6 faces a dark place other than the display 7, for example, the wall 3 Since the screen 6 does not face the screen 7a of the display 7, a normal simulation cannot be performed.
In this case, the light receiving sensor 11 in the controller 6
Does not detect a raster luminescent spot, but always detects a non-light state in which no light is detected.

In such a situation, the timing generator 24 in FIG. 2 obtains a vertical blanking period based on the horizontal synchronizing signal HS and the vertical synchronizing signal VS as shown in FIG. Further, as shown in FIG. 7, the timing generator 24 resets the reset A based on the horizontal synchronization signal HS and the vertical synchronization signal VS within the obtained vertical blanking period.
And a reset B signal. These signals are
Each signal is a binarized signal indicating a specific timing.

More specifically, in FIG. 7, the first to twentieth lines of the image signal indicate a vertical blanking period. During this vertical blanking period, the "0" pulse of the HS signal is counted after the VS signal becomes state "1", and a "0" pulse is generated at an arbitrary count number, and this pulse is reset A Signal. This arbitrary count number is set to fall within the vertical blanking period.
Further, a “1” pulse is generated during a period from when the VS signal changes to the state “1” to when a “0” pulse of the reset A signal is output, and this pulse is used as a reset B signal.

These reset A signal and reset B signal are sent to the count control unit 26 in FIG. The counting control unit 26 inputs a light receiving signal in addition to the reset A signal and the reset B signal. However, in the case where it is considered now, that is, when the gun type controller 6 is facing a dark place other than the display 7, the light receiving signal is input. The signal is always "1" (no light).

In this case, as shown in FIG. 10, the counting control section 26 combines the light receiving signal "1" with the reset A signal to generate the S signal and the E signal at predetermined timing.
These signals are sent to the X-coordinate counter 27, the first Y-coordinate counter 28, and the second Y-coordinate counter 29 in FIG. Now, considering the first Y coordinate counting section 28, this counting section counts the HS signal in FIG. 10 using the VS signal as a count start signal and the S signal as a count stop signal. In the case of the figure, "9" is obtained as a specific value instead of the Y coordinate value as a result of this counting. On the other hand, the X-coordinate counting section 27 counts the counting clock signal based on the HS signal and the S signal, thereby similarly obtaining the X signal.
A specific value instead of a coordinate value is obtained. Now, assuming that this specific value in place of the X coordinate is “a”, a fault information signal (a, 9) is obtained as specific information in place of the position information by the processing in the vertical blanking period described above.

When the processing in the vertical blanking period is completed as described above, the video processing shifts to the scanning period of one frame. Since the situation in which the gun-type controller 6 faces a dark place other than the screen 7a is considered now, even if the raster luminescent spot scans and moves within the screen 7a during the scanning period, the luminescent spot remains in a gun-shaped manner. Light receiving sensor 11 in controller 6
Cannot be detected. Therefore, the output signal of the light receiving sensor 11, that is, the light receiving signal always remains "1" (no light).

In the state shown in FIG. 10, after the fault information signal (a, 9) is generated in the section 1, a light receiving signal "0" pulse is generated at an appropriate timing in the section 2. This situation is a normal situation in which the gun-type controller 6 faces the screen 7 a of the display 7.
It is considered that this is the case where a raster luminescent spot is detected by the light receiving sensor 11 in the above. In this case, a new counting process is executed based on the newly generated light receiving signal “0” pulse, and thus the vertical The fault information signal “9” obtained during the blanking period is replaced with a new count result “Y”. The same applies to the X coordinate. Therefore, the position information output from the position calculation circuit 13 (FIG. 1) during the next vertical blanking period is position information indicating the coordinates of the raster luminescent spot, and thus the failure information signal (a, 9) has no special meaning.

On the other hand, in the situation where the light receiving signal always remains "1" (no light) within the scanning period of one frame, as is now considered, a fault occurring during the vertical blanking period is generated. The information signal (a, 9) is continuously output from the position calculation circuit 13 (FIG. 1). Then, the CPU 17 (FIG. 1) that has received the failure information signal, according to the program stored in the ROM 19, controls the gun type controller 6
Recognizes that the screen 7a does not face the screen 7a normally, and executes a predetermined calculation corresponding thereto. For example, a notice such as "The muzzle is not facing the screen" is displayed on the screen 7a. Upon seeing this, the player can correct the gun-type controller 6 to a normal state facing the screen 7a, so that a stable shooting simulation can be continued.

(3) Continuous light enters the gun-type controller As one specific example of this case, the gun-type controller 6
May be facing a bright place other than the screen 7a. In this case, naturally, the controller 6 cannot indicate a position in the screen 7a. As another specific example, a situation in which the gun-type controller 6 faces the screen 7a but continuous light coming from another place enters the controller 6 can be considered. In this case, since the raster luminescent spot cannot be detected due to the disturbance of the continuous light, a normal position cannot be specified.

Under such circumstances, as shown in FIG. 6, the timing generator 24 in FIG. 2 calculates the vertical blanking period based on the horizontal synchronizing signal HS and the vertical synchronizing signal VS. During the vertical blanking period, a reset A signal and a reset B signal are generated based on HS and VS, and these reset A signal and reset B signal are transmitted to the count control unit 26 in FIG. Can be

Since we are considering a situation where continuous light enters the gun-type controller 6, the light receiving signal entering the counting control unit 26 is always "0" (light receiving). Therefore, in this case, as shown in FIG. 11, the counting control unit 26 combines the light receiving signal “0” with the reset B signal to generate the S signal and the E signal at predetermined timings different from those in FIG. . These signals are shown in FIG.
7. It is sent to the first Y coordinate counting section 28 and the second Y coordinate counting section 29.

Now, considering the first Y coordinate counting section 28, this counting section in FIG. 11 uses the VS signal as a counting start signal, the S signal as a counting stop signal, and
Count the signal. In the case of the figure, “4” is obtained as a specific value instead of the Y coordinate value as a result of this counting. On the other hand, regarding the X-coordinate counting unit 27, a specific value instead of the X-coordinate value is similarly obtained by counting the counting clock signal based on the HS signal and the S signal. Now, assuming that the specific value relating to the X coordinate is “b”, a fault information signal (b, 4) as specific coordinate information is obtained by the above processing within the vertical blanking period.

When the processing in the vertical blanking period is completed as described above, the video processing shifts to a scanning period of one frame. Since the situation currently considered is a case where continuous light is incident on the gun-type controller 6, even if the raster luminescent spot scans and moves within the screen 7a during the scanning period, the luminescent spot remains within the gun-type controller 6. Can not be detected by the light-receiving sensor 11, and the output signal of the light-receiving sensor 11,
It always remains "0" (light reception). As a result, the fault information signal (b, 4) generated within the vertical blanking period
Is continued as it is and output from the position calculation circuit 13 (FIG. 1). Then, the CP receiving the failure information signal
U17 (FIG. 1) recognizes that continuous light is incident on the gun-type controller 6 and cannot perform a normal position indication according to a program stored in the ROM 19, and executes a predetermined operation corresponding thereto. . For example, a notice such as "Please remove continuous light" is displayed on the screen 7a. The player who sees this can correct the gun-type controller 6 to a normal state facing the screen 7a, or move the light emitting source near the screen 7a away from the screen 7a, thereby providing a stable shooting simulation. Can be continued.

As is clear from the description in each of the above situations, in the present embodiment, different reset signals are combined with the light receiving signal in accordance with the binary state of the light receiving signal during the vertical blanking period. A specific coordinate value corresponding to the binary state of the light receiving signal is generated. As a result, when light does not always enter the gun-type controller 6 or when light continues to enter the gun-type controller 6, a specific value can be assigned as the position information signal. Therefore, judging from this specific value, it can be easily and reliably recognized that the gun-type controller cannot operate normally. In addition, since a method of assigning a specific value to the position information signal is employed, no special determination operation is required, so that the circuit structure can be extremely simplified. In addition, a failure of the light receiving sensor can be determined.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the embodiments, and can be variously modified within the technical scope described in the claims. For example, the position pointing device according to the present invention is not limited to the shooting simulation device, as long as it is a video display device of a type that displays an image in the screen by visually synthesizing a bright spot in the screen, It can be used to indicate a desired arbitrary position on the screen. Further, the external shape of the position indicator is not limited to the shape imitating a gun, but may be any other shape as necessary.

According to the position pointing device according to the first aspect and the shooting simulation device according to the eighth aspect, the position indicator such as a gun-shaped casing or the like is used to determine a luminescent spot appearing on the screen of a video display device such as a CRT display. An abnormal state that cannot be detected normally, specifically, an abnormal state in which the luminescent spot cannot be detected because continuous light is received, or an abnormal state in which the position indicator points to a bright place other than the screen. Sometimes, these abnormal states can be reliably detected. Further, when such an abnormal state is caused by a failure of the light receiving sensor, the failure can be determined.

The position pointing device according to claim 2 and claim 9
According to the shooting simulation apparatus described above, an abnormal state in which a position indicator such as a gun-type casing or the like cannot normally detect a bright spot appearing on a screen of a video display device such as a CRT display or the like, specifically, the position indicator is displayed on a screen.
