20080223131 | System and Method for Motion Capture in Natural Environments - A system captures motion data in natural environments. A set of sources and a set of sensors are arranged on an object such as a human body. Each source emits ultrasonic signals detected by the sensors. A driver module is also arranged on the body. The driver module generates the ultrasonic signals for the set of sources and timing signals for the set of sensors. Distances between the set of sources and the set of sensors are measured based on a time of flight of the ultrasonic signals. Three dimensional locations of the set of sources and the set of sensors are determined from the distances. The distance measurements are refined using inertial components that provide rotation rates and accelerations. All these measurements together yield poses or configurations of the object. | 09-18-2008 |
