First Claim
Patent Images
1. A motion analysis system for analyzing the motion of an individual moving an object from a first position to a second position, said system comprising:
- a first sensor attached to a first portion of an individual for detecting the position and orientation of said first portion of said individual and producing a signal representative of said position and orientation;
an analyzer for receiving said signal from said first sensor, wherein said analyzer calculates a moment of said first portion of said individual based upon said received signal; and
an indicating mechanism that produces a sensory signal that is representative of the magnitude of said calculated moment.
