We are having a problem with the calibration of our Polhemus patriot tracking device running through Vizard as per 'SekulerExperiment.py' that you wrote for us. We started PiMGR, set up the hemisphere tracking, and closed it again, and run the experiment file in Vizard. We keep the orientation sensor in the same place every time, and calibrate with the glove in the same position. Yet every time we do that, the glove starts in a different position on the screen. This is with the same subject in the same location, same arm length and position, and everything. Any clues as to why this happens? Has anyone else experienced this in their testing?
