Abstract: A walk simulation apparatus usable for walk training of crippled persons or for a simulator of virtual reality. By the apparatus participants can experience simulations of walking horizontally and on slopes and steps with full reality at the same position. The apparatus is of use also in quantitatively evaluating quality of performances of artificial legs for patients who lost legs. The apparatus comprises a head mounted display showing a participant programmed images in the form of three-dimensional images, a walk surface mechanism having a function of performing simulations of horizontal walk and walk on slopes and steps, a control device, walk plates, and load sensors detecting loads applied on the walk plates individually. The control device has a function of comparing data detected by the load sensors with standard data to analyze a state of walk of the participant.
