My lab currently houses a ProReflex Motion Tracker. I'm anxious to find a large (55'') touchscreen to display visual stimuli for simple reaching experiments. However, the touchscreen I've tested gives off huge reflections, which interfere with the motion tracking. These reflections occur when the hands approach the touchscreen, so are presumably not caused by ambient light, but rather the reflections off the screen from the IR of the ProReflex. Has anyone else had similar problems, or managed to find a good visual display that doesn't reflect badly?

Re: Touchscreen surfaces compatible with optoelectronic tracking systems
I have had similar problems for reflections off the floor when markers get too close. Messing with the camera positions, gains, and strober power can often help, but will probably not completely eliminate it. Have you looked into non-reflective films or screen protectors you could cover the screen with? A matte-finish privacy filter, window film, or even lots of smartphone screen protectors tiled across the screen may help reduce these reflections further. Just make sure that your touchscreen will work through it.
