옴니 풀리 기반 전방향 트레드밀 개발

다국어 초록 (Multilingual Abstract)

Locomotion interface with a virtual reality environment can enhance immersiveness of a user due to the increased proprioception and real energy consumption. An Omni-Directional Treadmill (ODT) is considered as one of these devices; it can facilitate human movements such as walking, running and turning. It can provide 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. Besides, their significant limitation is slow acceleration and deceleration; which makes them inadequate for applications such as gaming and training of soldiers in virtual environment. Therefore, this paper suggests a novel design of a Fast Omni-Directional Treadmill (F-ODT). The proposed system is simpler, lightweight and produces a high power transmission efficiency based on the suggested Omni-pulley mechanism. Dynamic analysis of the design is performed using simulation program ADAMS® to calculate the drive power, and the required drive motor are selected accordingly. Furthermore, prototype of the F-ODT system is developed according to the proposed design and the capability of the system to provide rapid acceleration is validated. The proposed F-ODT system will be used as a locomotion interface platform in various virtual reality environments such as training of soldiers, gaming, educational experiences and gait rehabilitation. Future task is integration of the F-ODT with a motion capture system and a display system for immersive virtual reality experience.
