This paper presents a new locomotion interface device for walking about in virtual space. Traveling on foot is the most intuitive way for locomotion. An infinite surface driven by actuators is an ideal device for creating a sense of walking. We selected a torus-shaped surface to realize the locomotion interface. The locomotion platform employs twelve sets of treadmills. These treadmills are connected side-by-side and driven in perpendicular direction. The effect of infinite surface is generated by the motion of the treadmills. The walker can go in any direction while his/her position remains localized in the real world. The device is applied to study human performance on spatial recognition tasks.
