Abstract:
A tracking sensor integration system presented herein collects sensor data obtained for each time frame by a plurality of sensors attached to a wearable garment placed on a user's hand. A controller coupled to the tracking sensor integration system calculates a measurement gain based at least in part on collected sensor data, and determines prediction for a pose of the user's hand for the current time frame using the collected sensor data and a plurality of estimation parameters for the current time frame. The controller then updates the estimation parameters for the current time frame, based in part on the measurement gain and the prediction for the pose of the user's hand. The controller determines an estimated pose for the user's hand, based in part on the updated estimation parameters and the collected sensor data.
