The camera hand-tracker has some advantages over gloves other than the
obvious one of convenience to the user:

    It doesn't need to be calibrated to produce useful flexure information
    for the fingers; the light fiber sensors on the Dataglove (tm?)do have
    to be calibrated at least everytime you put them on if you want any
    degree of precision in the measurements.

    If the cameras can be automatically swivelled to follow the user, the
    operating volume is much larger than for the Polhemus sensor in the
    Dataglove.

    You can get information on the position and orientation of the arms.

One thing that you could do with the cameras is wave your hands as if
conducting an orchestra, or playing an instrument.
