Abstract: A locomotion platform is composed of a platform main body, a waist holding device, a signal fetching circuit, and a monitoring system. The platform main body consists of a platform structure body, a perforated platform face plate, position sensors, and balls located over the position sensors. The waist holding device consists of a waist ring for catching the waist of a user, and a fastening member for fastening the waist holding device with the platform structure body. The signal fetching circuit is intended to fetch the signals generated by the position sensors. The monitoring system is intended to receive the output signals of the signal fetching circuit and is provided with a software for computing the displacement generated by the strolling of the user on the platform main body. The results of computation are exhibited on a monitor.
