The Gait Sensing Disc - A Compact Locomotion Device for the Virtual Environment
نویسندگان
چکیده
The locomotion device is an input interface, which can sense the walking pace and direction of the user, for the virtual reality system. This paper presents a new type of locomotion device called Omni-direction Ballbearing Disc Platform(OBDP), which allows the user to walk naturally inside the virtual environment. Instead of using the 3D tracker, arrays of ball-bearing sensors on a disc are used to detect the pace and an orbiting frame to identify the walking direction. No other sensor, except the head tracker to detect the user’s head rotation, is required on the user’s body. In addition, the ball-bearing on the sensor slips the user’s foot back to the center position of the disc. A prototype of the overhead crane training simulator that fully explores the advantage of the OBDP is also designed and introduced in this paper.

Locomotion is an virtual reality interface that enables the user to walk inside the virtual environment in any directions over a long distance without actually leaving the physical device. In order to enable the user to freely navigate the virtual world and get fully immersed into the virtual environment accordingly, a locomotion device must fulfill the following two distinct requirements. Firs...
