I have acquired a pair of the Vuzix VR920 iwear video glasses with head tracking ability. They connect right away with the ez-software. My Roll seems to be my Yaw. I have to roll the glasses in order to move the red dot sideways and the yaw has no effect. The settings do not have any items to adjust for this. Any ideas on how to adjust the script to fix this problem? In my calibration program and demos the glasses work great. Only in the ez-software is a problem. Using Win7 and the original ez-software with ez-b v3. Downloaded the newest software but wasn't compatible with my v3 (bluetooth and firmware errors) for some reason. Hate to just throw out a $100 board I haven't had a year just because of a software and hardware upgrade by the mfg.
