In this paper, the construction of a wheelchair training system in virtual space was studied. In the system, the motion equation was made on a four-wheel model, and the model was constructed for the wheelchair in a computer. The motion of wheelchair was calculated from the force applied to the hand rim. The calculated results were combined with inner sensors to give force and visual presentations. In inner force sense presentation, the resistance received from the road surface was controlled with a motor, and manipulation senses such as traverse traveling on slope and passing over step can he obtained through the operator's body. In visual sense presentation, information support was carried out by showing the operator information such as risk of collision and the way to avoid it, in addition to various training environments. From the above, the training reality was improved towards high efficiency and effectiveness.
