Abstract

Motion tracking has shown promise as a powerful technique to improve interaction function in Virtual Reality (VR). Users can interact naturally with virtual environment by using body motion as the interface. This paper presents a design of a telescope-style interaction system combined with an inertial/magnetic motion tracking unit for users' interacting with the virtual environment and a near-to-eye display system supplying visual virtual environment to users. Since the movement acceleration will cause the error of accelerometer measurement, users will feel uncomfortable and cannot interact well with the virtual environment because of pictures' jitter. To enhance the user's immersion in the virtual environment, a Kalman filter is designed to ensure the accuracy of users' motion information. Performance of the estimation's precision is shown in the experiments and results.
