Abstract
A method based on the Kalman Filter for deriving whole-body segment ac celerations from position tracking data is described. Such a procedure is experimentally calibrated and qualified as a Virtual Accelerometer supplying a resolution of 0.2 m/s(2) and a relative accuracy of bette r than 10 percent rms within 0-8 Hz bandwidth. Results are finally com pared to accelerometer performances reported by previous investigators .
