ABSTRACT:
A virtual reality simulation apparatus providing participants with simulations of horizontal walk and walk on slopes and steps with full reality in their feelings in their bodies. The apparatus comprises a walk surface mechanism including a pair of walk plates supporting a participant's feet, a foot bottom-position detecting device for detecting positions of feet-bottoms of the participant moved away from the walk plates, and a walk-plate horizontally-driving device, which horizontally shifts the walk plate, correspondingly to movements of the participant's feet, to cause the foot-bottom to be contacted on the walk plate and keep the participant's trunk in a fixed position. The apparatus has a miniature space and camera mechanism including a miniature space and a camera device which is movable in the miniature space to be placed in a direction imitating a view of the participant and take an image in the miniature space. A control device mixes a previously programmed image and an image taken by the miniature space and camera mechanism to transmit the composite image to an image display and show it to the participant, and controls the walk surface mechanism while causing the same to correspond to the images.
