碩士 === 國立政治大學 === 資訊科學系 === 107 === Recently, improvisational performance using wearable devices combined with virtual reality (VR) or interactive technology has become a new type of digital art performing. Our previous research results have developed a platform that can “capture” the body gesture using wearable devices to render appearance of virtual objects for art performance. However, it still need the real-time position tracking of the performer to make the performance smoothly and naturally. Previous related works regarding the positioning techniques mostly focused on the error distances. They cannot be directly adopted in the practical performing art due to unsatisfactory real-time position tracking. The goal of the research is to achieve acceptable tracking performance using only IMU wearable sensors. We inspired from many methods by lots of experiments, a real-time positioning with “foot-step” and “direction-judge” tracking algorithm is proposed to solve this problem. The experiment results are satisfactory with very good feasibility. We hope the platform can enrich the performing patterns in digital arts, and empower the cultural innovation and integration capability of software and hardware industry in Taiwan.
