BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face orientation discriminating device which is applied to a window outside visual field switching device of a simulated visual field device.

[0002]

2. Description of the Related Art In a simulated visual field device, it is necessary to detect the visual line direction or the face orientation in order to generate a simulated visual field outside the window. There is an eye camera as a conventional line-of-sight direction detection device, but this is unnatural unlike people who see the scenery in a natural state because the device is installed in front of the face, and wiring for extracting the detection signal Was needed.

There has never been a device that allows a person to wear the device in a natural state and has no external wiring.

[0004]

In the conventional device, it is necessary to mount the device in front of the face or connect it by external wiring. In the former case, the movement of the person becomes unnatural, and in the latter case, The wiring is entangled in the human body,
There was a problem such as cutting.

The present invention aims to solve the above-mentioned problems.

[0006]

SUMMARY OF THE INVENTION A face orientation discriminating apparatus of the present invention is a reflector provided on a rear portion of a helmet, and is provided at a constant interval between the reflector and the reflector. It is characterized in that a projector for irradiating light and a light receiver for receiving reflected light from the reflecting plate are provided and a photoelectric switch for outputting a detection signal of light is provided.

[0007]

In the above, when the trainee wearing a helmet swings his or her face, the helmet and the reflector plate rotate accordingly, and when the rear part of the helmet faces directly behind, the reflector plate is on the optical axis of the photoelectric switch. Then, it becomes a state of forming an angle close to 90 ° with the optical axis. At this time, the photoelectric switch outputs a detection signal (hereinafter referred to as "ON"), and at other positions, the photoelectric switch does not output a detection signal (hereinafter referred to as "OFF").

From the above, in the direction of the rear part of the helmet,
Since the output of the photoelectric switch is turned on and off, it is possible to determine whether or not the trainee to be trained using the simulated visual field device is oriented in the same direction as the optical axis of the photoelectric switch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. This embodiment shown in FIGS. 1A and 1B is
Reflector 3 provided on the rear part of helmet 5, and a projector 6 for irradiating the reflector 3 with light at a constant interval and the reflected light from the reflector 3. A light receiver 7 for receiving light is provided, and a photoelectric switch 4 for outputting a light detection signal is provided.

In the above description, the reflection plate 3 attached to the helmet 5 is on the optical axis of the photoelectric switch 4, and only when the angle formed by the optical axis and the optical axis is about 90 °.
Outputs a detection signal.

When a trainee or the like wearing the helmet 5 shakes his / her face, the helmet 5 and the reflection plate 3 rotate accordingly, and at a certain position, the reversal plate 3 causes the photoelectric switch 4 to move.
On the optical axis of, the optical axis and the optical axis form an angle close to 90 °.
At this time, the photoelectric switch 4 outputs the detection signal, and at other positions, the photoelectric switch 4 does not output the detection signal.

According to the above, the output of the photoelectric switch is turned on and off depending on the direction of the rear part of the helmet, so whether or not the trainee is facing the same direction as the optical axis of the photoelectric switch, such as when training using a simulated vision device. Can be determined.

The case of controlling the simulated visual field apparatus using this embodiment will be described with reference to FIGS. 2 (a) and 2 (b). 2 (a) and 2 (b), 1 and 2 are monitors to be trained by the trainee, the monitor 1 is installed for the field of view outside the window in front of the trainee, and the monitor 2 is the field of view outside the window on the right front side. It is installed for. The monitors 1 and 2 are for displaying an out-of-window view by computer graphics.
The images displayed on 2 need to display different views depending on the respective directions, but both monitors 1 and 2 are supposed to display only images in one direction in order to simplify the simulated field of view device. In this system, it is determined which monitor the trainee is looking at and the corresponding image is displayed on both monitors 1 and 2. That is, when the trainee is looking at the front monitor 1, a front window view image is displayed on the monitors 1 and 2, and when the trainee is looking at the right front monitor 2, the right front window view image is displayed. It is displayed on the monitors 1 and 2.

In the above apparatus, the reflector 3 is on the optical axis of the photoelectric switch 4 when the trainee is looking out of the front window, and is arranged so as to form an angle of about 90 ° with the optical axis. At this time, the photoelectric switch is turned on and this signal is sent to the simulated field-of-view device, and the device displays a front window outside view image on both monitors 1 and 2. Also, when looking in other directions, the photoelectric switch is turned off due to the reflection plate deviating from the optical axis or the angle with the optical axis deviating by more than 90 °, and the simulated field-of-view device that receives this signal is trained. The person determines that he is looking at the monitor 2 in front of the right side, and the above-mentioned device displays the outside view image of the window in front of the right side on both monitors 1 and 2.

A second embodiment of the present invention is shown in FIG. In the present embodiment shown in FIG. 3, a plurality of photoelectric switches 4 in the first embodiment are arranged, and it is possible to cope with the vertical and horizontal changes in the position of the trainee.

A third embodiment of the present invention is shown in FIG. In this embodiment shown in FIG. 4, the photoelectric switch 4 in the first embodiment is installed at two places, and the orientations of the face in three directions can be discriminated. The photoelectric switch 4 may be arranged in a spherical shape centered on the head of the trainee, so that the arbitrary direction can be determined.

[0017]

According to the face orientation discriminating device of the present invention, the reflection plate provided on the rear portion of the helmet reflects the light from the projector provided on the photoelectric switch, and when the reflection plate has a predetermined angle, the reflection is performed. Light is incident on the light receiver, and the photoelectric switch outputs a light detection signal to determine whether the trainee or the like to be trained using the simulated visual field device is oriented in the same direction as the optical axis of the photoelectric switch. It is possible to realize a device that does not require external wiring.
