Abstract
The Gait Master is a locomotion interface that creates sense of walking on uneven surface. The device employs a turntable on which two motion platforms are mounted. The motion platforms trace the feet and carry them back to the neutral position. The user an physically walk in a virtual space while the position is maintained.The motion platforms move vertically, which simulates uneven surface. The walker can climb up or go down a virtual stair case while the position is maintained. The turntable rotates the motion platforms, so that the walker can walk in any direction. We have developed two prototypes and evaluated them through user studies.
