Sb. Bortolami et al., NUMERICAL DIFFERENTIATION OF TRACKING DATA OF HUMAN MOTION - THE VIRTUAL ACCELEROMETER, Journal of dynamic systems, measurement, and control, 119(2), 1997, pp. 355-358
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
.
