Patent attributes
Techniques for capturing and analyzing motion made by a person performing activities are described. According to one aspect of the present invention, sensing devices are attached to different parts of a body. As a person makes moves, the sensor modules, each including at least one inertial sensor, produce sensing data that are locally received in one designated sensing device that is in communication with an external device either remotely or locally. Relying on the resources on the external device, the combined sensing data received from the these sensing devices are processed and analyzed to derive the motions made the person. Depending on applications, various attributes of the motion can be derived from the combined sensing data, where the attributes can be incorporated into an application running on a mobile device for 3D graphics rendering into a human avatar animation and motion chart analysis.
