Abstract
In recent years, extensive research and development have been carried out for devices and software that interact with the virtual reality environment. Omni-directional treadmill (ODT) lies among such devices; it simulates a human locomotion such as walking and running. It provides a two-dimensional locomotion interface function for interacting an avatar in the virtual environment and the user in the real environment. Existing Omni-directional treadmills are heavy, complex and exhibit low power transmission efficiency. Their substantial drawback is limitation of rapid acceleration and deceleration, which make them inadequate for applications that require high acceleration and deceleration, such as training of soldiers in virtual environment. Therefore, this paper suggests a novel design of Omni-directional treadmill. Our proposed system is simpler, lightweight and produces a high power transmission efficiency based on the suggested Omni-pulley mechanism. Besides, we performed the dynamic analysis of our design using simulation program ADAMS® and calculated the drive power, and selected the required drive motor based on the results. Furthermore, we developed and drove a prototype of the designed system, and could discover a capability of system. The proposed device will be used as locomotion interface platform in various virtual reality environments such as training of soldiers, gaming/educational experiences and gait rehabilitation. Future task is implementation of the whole system based on suggested design.
