Abstract

PROBLEM TO BE SOLVED: To reduce attachments to a head part for enabling the presentation of an image in almost all directions by a TV set connected to a chair, moved by the rotation of the chair on a rail circularly laid and interlocked with a tilt pedal to move vertically. SOLUTION: An operator 20 rotates a chair 10 in the desired direction when he wants to move the image presenting direction or the direction of a camera 40 on a camera bed 41 in the horizontal direction and operates the image presenting direction and camera direction by pedalling a pan-pedal 11 when the wants the vertical movement of the camera. When the pan-pedal 11 is pedalled on the front, the image presenting direction and the camera 40 direction are moved upward and when the pan-pedal is pedalled on the rear, these directions are moved downward. Thus, the image can be presented horizontally in all directions and since the picture face of TV is always in the front of the operator, a stereo-image is liable to be presented.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image presentation direction and camera direction operation device in a remote operation system using a virtual reality or visual system.

[0002]

2. Description of the Related Art Generally, an HMD (Head Mounted Disp) is used as an image display device when experiencing virtual reality or performing remote operation with a high sense of presence.
lay) has been used. What is HMD?
As disclosed in Japanese Patent No. 923, a stereoscopic image is reproduced by presenting images corresponding to the eyes in front of the left and right eyes of an operator, and camera direction operation is performed using a visual direction detection sensor or a head posture sensor. It is a device.

Such an HMD is capable of presenting an image in all directions of 360 ° in accordance with the viewing direction, and has a feature that, in remote control, the camera can be operated in the direction of a remote location in real time.

As a remote control device that does not use an HMD, there is a robot control device using a stereoscopic projector disclosed in Japanese Patent Laid-Open No. 2-83194. This device is an operation panel fixed to the operator's feet and operates the image presentation direction and the camera direction.

[0005]

At the present time, the HMD having a high screen resolution has a heavy weight and is difficult to wear for a long time, and the light weight has a lack of a resolution. There is a problem that the operator may feel unstable because the surroundings cannot be seen because it is covered by the presentation surface.

Further, in the robot operating device disclosed in Japanese Patent Laid-Open No. 2-83194, since the operation panel is fixed, H
There are problems that it is not possible to present an image of 360 ° in the horizontal direction like MD, and that the operation in the image presentation direction and the camera direction cannot be intuitively performed due to the panel operation.

In order to solve such a problem, the present invention provides an image direction and camera direction operation device that reduces the amount of head wear, can display images in almost all directions, and allows more intuitive direction operation. The purpose is to provide.

[0008]

According to the present invention, the direction of image presentation and the operation of the camera can be controlled by rotating a chair and a tilt pedal attached to the chair, a pan pedal and a tilt pedal attached to the chair, a posture of a head, a chair. Do either in the rotation and the direction of the line of sight. Also, the image presentation method is performed by any of a stereoscopic television, a stereoscopic projector, and a combination of a stereoscopic projector and a wide-angle projector.
The TV stand and the projector stand may be connected to a chair and move together with the chair, or may be connected to a chair and move by itself.
