PhaseSpace Inc., a leader in the Motion Capture/Motion Tracking industry, is bringing motion capture out of the laboratory and into the field, using combinations of state-of-the-art sensors placed on the body, and collecting motion data onto a data storage device. Up to eight hours of physical activity can be collected for later downloading into a skeletal frame animation software to show, for instance, differences in pace, lift, reaction time, etc. over the course of various field exercises. Being able to measure fatigue effects can help in planning unit tasks, and can also provide information on individual readiness. Tracking motion is the first step, but the same methods of data collection and storage can be used to add other physiological data (heart rate, body temperature, etc.).
