IRs and motion tracking


    Mar 20 2006 | 5:23 am
    hello all,
    we are doing a project for the end of semester, and what I am looking
    for is an advice about the approach I should take in this scenario.
    The setup will be a IR camera and back-side projection and IR leds
    that is reflected on a sheet, so when the user puts his hand on the
    other side of the sheet, I am assuming it will intersect the the
    reflection of the IR and stand out from the background. So it will
    be a black/white screen where the user touches will be going to the
    opposite color than the rest. What kind of approach should I take for
    this? Is there any externals that make my job easier?
    Thanks in advance
    ilteris.
