Detachable Wireless Motion System for Human Kinematic Analysis

摘要

A system for determining user kinematic characteristics includes a detachable motion sensor, a processing system, and a wireless transceiver. The motion sensor may be coupled with a user's footwear in order to generate one or more signals corresponding to the motion of the user's foot/feet. The processing system is in communication with the motion sensor and is programmed to use the one or more signals to determine one or more kinematic parameters. The present invention measures various parameters about each individual stride. The stride based kinematic characteristics may include, but are not limited to, pitch, roll, yaw, vertical position, horizontal position, horizontal velocity, vertical velocity, distance traveled, foot strike, foot strike classification, toe off, contact time, stride rate, stride length, rate of pronation, maximum pronation, rate of plantarflexion and dorsiflexion, swing velocity, and pitch-roll signature.

主权项

1. A detachable wireless measurement device capable of determining stride kinematics in each of a plurality of strides, comprising:
a detachable receptacle which securely holds the kinematic sensor to the user's footwear; a kinematic sensor which is comprised of a three-axis accelerometer and a three-axis gyroscope; said kinematic sensor calculating the orientation from the accelerometer and gyroscope readings, then further determining stride kinematic metrics.
