Abstract

We aim to provide an interactive and entertaining environment for users to better enjoy and stay motivated during indoor training. We are now developing a virtual treadmill-based training system that will allow users to experience walking or running around various real scenes. The images are displayed according to the user´s speed. We use a set of key frame 360-degree panoramic images on a grid to synthesize, in real-time, an omnidirectional movie for any possible path the user takes. The playback smoothness of the synthesized movie depends on the separation (grid pitch) between key frames. Preliminary experimental results help us determine the largest playback grid pitch without compromising the playback smoothness.
