Applying Virtual Reality for In-Door Jogging

We propose an "In-place Virtual Tour" system that generates the smart virtual environment adapting to a user\´s activities when jogging. Our proposed system automatically detects the main region of frames captured from a regular camera, analyses the difference in foreground in the main region of consecutive frames to estimate the user\´s intensity level, then renders virtual scene with appropriate speed. The system does not require any special devices as existing interactive fitness games. Experimental results demonstrate the effectiveness and the realtime manner of the proposed system. Our proposed method can also be applied to develop various exciting interactive games to stimulate excitement for users when doing in-door fitness exercises or to create virtual environment for museums where visitors just stay in place to explore scenes in museums.
