Adjusted the dimensions in the software from default to the closest number I could determine on the model. In either case, I see all three points on the screen, but when I move my head the skull does not track properly. For instance: When I turn my head to my right, the skull spins and turns upward. When I turn my head to my life, the skull barely moves at all. When I turn my head up, the skul spins and turns upward like when I turn my head to the right. When I turn my head down, the skull 'zooms' in closer and points up in the air. The webcam is above the top point of the cap by at least a few inches, and is about a foot and a half away.

Measure them precisely and set them up in the "3 Points Cap" section under "Model Dimensions" in mm. Don't forget the Model position set-up either: Edited by Steph on 08/11/2012 at 10h25.

Perhaps I'll try the 'clip' model again as I had more success with that, except it wouldn't track me turning my head to the right... I'm guessing because the middle LED would be blocked by my head.
