I'm considering using one of these to build a multi touch screen. I have a few questions.
I see in the TrackerIR4 has a higher resolution, but it seems to be just additional widescreen space. I'm going to be building a 3x4 and need to make sure that the viewing angle is in proportion. I'm guessing that the Tracker3 might be closer to this.
Also, anyone know what the resolution is for the c120?
Last, anyone build a java jni to the api yet?
THANKS!

Re: TrackerIR3 / IRTrackerIR4 / C120 sizes
C120 - Resolution: 355 x 288
The camera resoultion difference would be a reflection of how acurate the camera itself is, and has nothing to do in relation to the screen size or aspect ratio of the monitor used.

Some additional information :
The TrackIR 4 and the OptiTrack FLEX:C120 have the same base resolution of 355 x 288. Both cameras use 2x horizontal sub-sampling to increase the horizontal resolution. They both have the same effective resolution, but it is represented differently. An additional benefit of the FLEX:C120 that is really helpful in tracking applications is the ability to adjust the electronic exposure and IR LED brightness.
