Description

[0001]
TECHNICAL FIELD OF THE INVENTION

[0002]
[Prior art]
Research on virtual space systems includes CAVE of the University of Illinois and CABIN of the University of Tokyo, which consist of a large screen with at least the front and left and right walls connected to each other. There is a room where you can work freely. As described above, in the conventional virtual space system, an image is projected on a wall surface, a ceiling surface, and a floor surface of a room, and an observer in the room views the movement of the image to experience the virtual space. Since these spaces are fixed, the observer does not feel a sense of acceleration, a sense of speed, or a sense of movement, and cannot sufficiently obtain a sense of reality as a virtual space.

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0006]
<B> Movable virtual space system The movable virtual space system allows the observer to observe the image projected on the display unit and experience the virtual space. The observer can move and move with the display unit. System. The observer performs movements such as front and rear, left and right, up and down, rotation, twisting, tilting, and vibration with and on the display, and experiences a virtual space having a sense of acceleration, a sense of speed, and a sense of movement. it can. The image may be any image displayed on the display unit, and includes an image, a moving image, and the like.
[0007]
As shown in FIG. 1, for example, a movable virtual space system 1 includes a VDO projector 21 for projecting an image, a reflecting mirror 22, a display unit 2 for displaying a screen, a moving body 3 on which an observer can ride, and a display unit. The display unit 2 includes a frame 23 that supports the display unit 2 and the like, a driving unit 4 that moves the display unit 2 and the moving body 3, and a control unit 5 that controls an image on the display unit 2 and the driving unit 4. The movable virtual space system 1 can be represented by a block diagram, for example, as shown in FIG. The display unit 2 and the moving body 3 are exercised by the driving unit 4, and the image on the display unit 2 and the driving unit 4 are controlled by the control unit 4. Thus, the control unit 4 can integrally control the movement of the display unit 2 and the moving body 3 and the image on the display unit. This control method can be performed using a conventional technique.
[0008]
<B> Display section The display section 2 displays an image and can be viewed by an observer. The display unit 2 includes, for example, a screen, a liquid crystal display, a cathode ray tube, a plasma display, and the like. In FIG. 1, the VDC projector 21 irradiates an image toward a mirror 22 and projects the image reflected by the mirror 22 onto a screen. Thus, a large image can be displayed on the screen even in a small space.
[0009]
The display unit 2 only needs to give an observer a feeling of immersion, and it is possible for one display surface to be relatively large. However, it is preferable that the display unit 2 has a plurality of surfaces, or a viewing angle of 180 degrees or more. For personal use, a head mounting display having a wide viewing angle is possible, but a projection type screen having a viewing angle of 180 degrees or more is desirable. In particular, a high-definition lens having a wide viewing angle that covers the entire field of view of the observer is desirable.
[0010]
It is preferable that there be sound together with the video, and the sound device may be two-dimensional. However, it is more preferable to use three-dimensional sound because the sense of presence is enhanced.
[0011]
<C> Athletic body The athletic body 3 may be anything as long as the observer rides and exercises. , Vehicles such as airplanes, and the like. It is preferable that the moving body 3 can move such as forward / backward, left / right, up / down movement, forward / reverse clockwise rotation, and vibration in each direction. As described above, the moving body 3 may be one-dimensional, two-dimensional, or three-dimensional, and may be a parallel movement, a rotating movement, a combined movement of parallel and rotation, or a movement of four or more axes. .
[0012]
Instead of the moving body 3, a walking person may be a moving body, and a system that can provide a virtual space, such as the display unit 2 and the control unit 5, may be attached to the attachment, and the user may exercise the virtual space by himself while carrying. As the display unit 2, a head mounting display having a wide viewing angle is suitable.
[0013]
<D> Drive Unit The drive unit 4 exercises both the display unit 2 and the moving body 3 or exercises only the moving body 3. In the case of FIG. 1, the driving unit 4 includes wheels at the lower part like a cart of the moving body 3, and the wheels rotate so that the display unit 2 and the moving body 3 move or rotate on the floor. Can be granted. The drive unit 4 is controlled by the control unit 5.
[0014]
<E> The control unit control unit 5 controls the image displayed on the display unit 2 or controls the driving unit 4 or links the image on the display unit 2 and the driving unit 4 with each other. It is controlled integrally. The control unit 5 can use a computer such as a personal computer to set the video and the movement of the driving unit by a program.
[0015]
<F> Application examples of the movable virtual space system There are many application examples of the movable virtual space system, and any combination of video and motion may be used. For example, vehicles in a theme park, games (shooting, hunting, athletics) (Skis, bobsled, yachts, etc.), car racing, etc.), vehicle driving practice (special work vehicles with limited field of view and operating means such as airplanes, helicopters, ships, tanks, etc.), simulations, vast buildings Simulated experience (factory, theater, exhibition hall, stadium, etc.), simulated experience of micro world, verification of design plan, etc.
[0016]
<G> Control Example of Motion of Video and Moving Body The control unit 5 allows the observer to experience a virtual space with a sense of realism without driving by performing full-automatic driving. In particular, if the driving such as speed and acceleration is completely linked with the image on the display unit, a virtual space with a sense of reality can be realized. Further, the control unit 5 controls the chair on which the observer is sitting, and tilts the chair back and forth, left and right, and twists it clockwise and counterclockwise in accordance with the image of the virtual space to increase the sense of realism. Can be enhanced. For example, when increasing the acceleration, the chair can be tilted backward to instantly increase the sense of acceleration. When climbing a slope, the chair is tilted backward to move the surrounding image downward and backward. When going down a hill, the chair is tilted forward to move the image upward and backward.
[0017]
When using the head mounting display mounted on the observer's head, the control unit 5 detects the left-right direction, the elevation angle, and the depression angle facing the observer, and the image cannot be recognized by a human according to the display direction. By linking in a short time, the display unit can be used efficiently.
[0018]
【The invention's effect】
According to the present invention, the following effects can be obtained.
<A> The present invention can provide a virtual space system with a sense of reality.
<B> Further, the present invention can provide a virtual space system that is close to reality, such as a feeling of speed, a feeling of acceleration, and a feeling of movement.
