Visualization of Human Motion via Virtual Reality Interface and Interaction based on It.

This paper presents the concept of ecological sports training and the initial developments based on biomechanics analysis, VR technologies, and visualization of interaction. Computation algorithms in robotics have been applied to biomechanics analyses including muscle force estimation. These technologies are widely used for the self-biomechanics training, in which an athlete accesses and evaluates the analyzed results on his/her own motions and will necessarily move toward the ecological training that considers interactions with the counterpart and the environment in a sport game. We develop a VR visualization system of musculoskeletal analysis that provides a realistic experience of the interactions to an athlete. We also report an initial evaluation of the interactions with the virtual counterpart in the virtual environments through the VR system.
