  • Saw a new system

    I happened to be watching Dateline NBC last night and saw a motion recording
    system that blew me away. The system consisted of sensors taped to various
    points on a dancers body (looked like duct tape - no mention of what type of
    sensors), then attached to an overhead cable system which was connected to a
    large bank of input devices of some type called a "flock of birds". From there
    the signal was somehow relayed and processed so that it produced instantaneous
    real time motion in a wire frame figure on the computer monitor. The story was
    about somone who was using this system to animate gas pumps for commercials. I
    was blown away thinking about the uses of such a system in biomechanics. It
    involved no video, simply sensors, cables and someone in motion. Does anyone
    out there know any more about this type of system? What is it's true potential?
    Are similar systems being used for research somewhere? How much odes a thing
    like this cost? What sort of devices are in the "flock of birds" set-up? What
    sort of sensors are being used? What type of software is required? Would
    appreciate any info you have.
