Abstract
Techniques for establishing a biomechanical model of a user performing motion are described. A plurality of sensor modules corresponding to a set of designated body parts (e.g., arms or legs) of the user generate sensing signals when the user performs a pose. Sensing data including accelerometers and/or gyroscopes data generated from the sensing signals is analyzed to detect a medio-lateral direction of each of the designated body parts to infer the pose from the captured motion of the user.
Claims15
A method for establishing a biomechanical model through motion capture, the method comprising:
- obtaining a set of sensing data in a computing device, the sensing data generated via a plurality of sensor modules, sensor modules respectively corresponding to designated body parts of a user, each of the sensor modules including one or more of inertial sensors generating a sensing signal representing a movement of one of the designated body parts;
- estimating respective sensor-to-segment (STS) quaternions of the designated body parts from the sensing data;
- estimating a medio-lateral direction of each of the designated body parts;
- and
- finalizing the medio-lateral direction using some or all of the sensing data from the sensor modules.
