An accurate data collection method for spatial motion using a sonic digitizer.
An accurate collecting method for spatial displacement data utilizing a sonic digitizer which works electronically and acoustically is described. The sequence of the operation of the digitizer system is explained. As an application, the study of elbow flexion-extension is presented. Finally, operational precautions for using this system are discussed.
