Method and system for tracking movement of a person with wearable sensors

Abstract

Methods and systems for tracking movement of a person, includes: arranging sensors of a motion tracking system on a person; tracking movement with the sensors at least while the person performs a movement; digitally estimating, with a computing device, a position of the first joint or the sensor on the second body member, wherein the position of the first joint is estimated using measurements of the first sensor and its position is estimated using measurements of the first sensor and the sensor arranged on the second body member. The position is estimated while the movement is tracked. The method further includes digitally computing, an acceleration of the estimated position while movement is tracked; digitally computing a first comparison between the computed acceleration of the estimated position and acceleration measurements of the sensor arranged on the second body member; and digitally determining the movement performed based on the first comparison.
