@greg I have a suggestion on how to increase calibration process of PSMove in dimension. By pressing START button head camera recalibrates in the center, but if you hold the button then it’s center can be fixed in real time.
If holding SELECT button and change controllers position in real dimension, in virtual space controllers will change starting point. Usually hands (d4vr controllers) not too far from the center of the SteamVR room, but for calibration i have to come to PC and blindly change Driver absolute offset parameters. For example X-135, Y-30, Z-77, but this parameters become irrelevant the next time you start Driver4VR
