That is why we hope that using this acoustic information will provide an additional tool for movement learning. But setting computer-processed video recordings to music provides only indirect access to an athlete's movements. The device is a metal plate of roughly 40 by 40 centimeters, sunk into the floor of the gym. It converts pressure on its surface into electrical charges. But we do try to find systematic structures, e.g. by varying the breadth or the pitch of the tones dependent on muscle mass and body measurements.
Rehabilitation is also all about re-learning basic movement patterns.
There are patients who are no longer able to communicate verbally. The sports scientists are now converting gymnastic dance to sound. For the first time, after listening to the tone-setting of simple ball hits, of straight jumps and steps, we are now hearing the forces expressed by a lengthy sequence of widely divergent movement processes.
