While the video-based measurement of eye movements, also referred to as "video-oculography" (VOG), has many advantages, it also suffers from a serious disadvantage which has not been solved yet: using images of the eye, how can we distinguish between a movement of the eye-in-the-head on the one hand, and a movement of the camera with respect to the head on the other? To distinguish between the two, we need additional information about the orientation and position of the camera with respect to the head.
