Patent attributes
A human gesture tracking system includes a sensor device with at least one sensor unit, where the sensor unit is configured to measure at least one of position in three dimensions of a portion of an operator's limb and orientation in three dimensions of the portion of the operator's limb, a processor configured to receive information from the sensor device so as to determine orientation and position displacement in six degrees of freedom of the operator's limb, and an activator that is coupled to communicate with the processor and is further actuated by the operator to designate a start time and an end time in which position and orientation displacements of the portion of the operator's limb are determined by the processor. During system operation, the processor determines position and orientation displacements of the portion of the operator's limb in tracking sessions, each tracking session is defined as a time period between the start time and the end time as designated by the activator. The processor further determines an initial position and orientation of the portion of the operator's limb at the start time of each tracking session and determines position and orientation displacements of the portion of the operator's limb during each tracking session in relation to the initial position and orientation for the tracking session.
