Development of feedback system of motor imagery and performance

We developed a feedback system of motor imagery and actual performance. For the visualization of motor imagery, we used a puppet-type motion-capture system with 3D animation software. To create computer graphics from actual movement, we captured the actual movement by digital video and analyzed the movement using motion-analysis software. We converted the kinematics of the movement to the BVH format to create computer graphics of actual movements. The movements of dart throwing were examined using this system, and learners of the game could compare their own motor imagery to their actual performance. This feedback system should be useful in motor-learning processes.
