1. Apparatus for motion tracking comprising:

  • a hand-held device comprising at least one accelerometer adapted to provide a first set of samples including multi-axis acceleration information;

    computational circuitry adapted to employ examination of at least part of the first set of samples for providing a second set of samples indicating a motion information included in the first set of samples, wherein examination of samples associated with a first axis uses at least one different parameter than used for examination of samples associated with a second axis; and

    hand motion tracking circuitry adapted to use the second set of samples for providing motion tracking output indication.
