This paper presents a locomotion interface system using a type of the treadmill called Ball array treadmill (BAT), which consists of a walking board, a belt conveyer and a turntable. Balls on the board rotate with the belt conveyer and the turntable changes belt conveyer direction. The two-dimensional sensor array is embedded under the walking board to detect the walker position. When a person walks in 2D direction on the board, sensors under the board detect the walker foot positions and the ball rotation draws him back to the center of the board. The system with the PID control of foot positions was constructed and it was made clear that a walker on the board remains within the board area while it walks on the board two-dimensionally. This walk cancellation realizes an infinite 2D walk-through environment in virtual worlds. The mechanical structure of this device is simple and suits the practical use well.
