Position Tracking Question/Inquiry

Hello all,

I am looking for a simple and effective way to gather X and Y data from a moving person(s) for a master’s project. I have dabbled in reactivsion and TUIO a little and found troubles in losing the fiducial marker. I am working on a mac and I have a small number of kinects at my disposal.

Does anyone mind offering any experiences with such endeavors or possibly a direction to look into? I would be eternally grateful!
