KINEMATIC DATA GATHERING SYSTEM FOR DETERMINING HUMAN MOTION IN ZERO GRAVITY.

RESEARCH IS TO BE DONE ON A THREE DIMENSIONAL ACCELEROMETER BASED KINEMATIC DATA GATHERING SYSTEM. IT IS ENVISIONED THAT FIVE SUCH ACCELEROMETER UNITS WILL BE PLACED AT KEY POINTS ON THE HUMAN BODY AND INTERCONNECTED TO ALLOW STICK PERSON MEASUREMENTS OF MOTION IN THREE DIMENSIONS, AS WELL AS ESTIMATES OF ENERGY EXPENDITURES. FOUR OF THE ACCELEROMETER UNITS WILL BE IN WRIST-WATCH FORM FOR ATTACHMENT AT THE WRIST AND ANKLES, AND THE LAST UNIT WILL BE BELT ATTACHABLE AT THE SUBJECT'S WAIST. ALL UNITS WILL CONTAIN SENSORS AND SENSOR ELECTRONICS. THE BELT UNIT WILL GATHER, PROCESS AND STORE DATA FROM THE LIMB UNITS FOR TRANSMISSION BY TELEMETRY OR HARD WIRE MEANS.
