i would go (went) with active trackers. <br>IR leds powered by a 3v watch battery like those led throwies. <br>ir leds are out there don't get the ones for remote but the high brightness ones. its cheap and it work.<br>
*but* (most common, halogen) theatre lights also give infrared, and will null your efforts. consider and experiment. <br>neon is IRfree, but ugly.<br><br><div class="gmail_quote">On Tue, Apr 1, 2008 at 6:05 AM, kevin <<a href="mailto:deerwolf@gmail.com">deerwolf@gmail.com</a>> wrote:<br>

Hi there, I'm looking to track a small point on a performer's instrument in a low lit space. I simply want to have the x/y values for this point. I've thought about tracking color but imagine the low light might make this difficult. So I've been more inclined to use infrared tracking, using a small infrared reflector and bathing the stage in infrared light, or just placing a small infrared emitting LED on the performer. Either solution would be fine, I am just concerned with cost and mostly simplicity - I need to get the tracking system up and running asap. Any thoughts would be much appreciated. Thanks for any help!<br>
