Abstract
A method allowing the synchronizing collection of motion and ground reaction forces data at the start of a sporting event which are received from motion and force sensors embedded in insoles worn in the user's footwear. Furthermore, this method allows synchronization of said data with video or television transmission, and if used during, for example, during ski racing, provides information of skis' pitch, roll and heading in a 3-D space, as well as linear and angular velocity, g-forces, and the location and distribution of pressure points and ground reaction forces transferred to the user's feet in a numerical or a graphical form.
Claims10
A system to synchronize the collection of motion and ground reaction force vectors received from a motion and force analysis system embedded in footwear with the start of a user's physical activities, wherein said motion and force analysis system comprising:
- motion processing element comprising a three-axis accelerometer, a three-axis gyroscope and a three-axis magnetometer;
- force processing element comprising multiplicity of force sensors;
- personal area network (PAN) radio interface to communicate with motion and force processing elements and external synchronization means;
- wide area network (WAN) radio interface to communicate with a remote computer server;
- GPS radio interface to obtain location coordinates;
- and
- a smart-phone based analysis application in communication with the motion and force processing elements and the remote server;
- is designed to analyze motion and balance of the user by estimating location of Center of Pressure (COP), timing of the COP location change, and the user's motion in relation to ground reaction force and wherein said motion and COP vectors and the GPS coordinates synchronized with the start of the user's activities are sent to the remote computer server.
