The stickers don't seem to be working too well for motion tracking. Their color values are so fickle and highly dependent on lighting. I did anticipate the lighting to give me trouble, but I'm really questioning the worth of dealing with this trouble. I think having a light in the curved space will ruin the ambiance of the projection. I am thinking of buying small LED flashlights and clipping them on a headband (much like Luke's headband, except I plan to buy pre-made LED lights, rather than wiring my own- see the picture. And, Luke, if you are interested, they make infrared LED flashlights exactly like these.) I think this will alleviate several concerns with the tracking. I still plan to use color tracking, and this way I can keep the area dark, I don't have to worry about what colors the viewers are wearing, and the color values I am tracking should stay fairly constant since they are their own source of luminance.
