Abstract:
Methods and apparatus for incremental prediction of input device motion. In one embodiment, the input device comprises one or more sensors adapted to output motional data of the input device as measured at a certain period. A prediction of input device motion is generated based upon the last prediction and a weighted error in estimate determined by the sensory output. According to one embodiment, the weight is calculated as a Kalman gain. In one embodiment, once the prediction has been generated, it is provided to a display update algorithm adapted to orient a navigational object upon an associated display screen.
