ABSTRACT
Normal subjects are able to change voluntarily and continuously their head-eye latency together with their compensatory eye movement gain. A continuous spectrum of intentlatency modes of the subject’s coordinated gaze through verbal feedback could be demonstrated. It was also demonstrated that the intent to counteract any perturbation of the head-eye movement, i.e., the mental set, permitted the subjects to manipulate consciously their vestibular ocular reflex (VOR) gain. From our data we infer that the VOR is always “on.” It may be, however, variably suppressed by higher cortical control. With appropriate training, head-mounted displays should permit an easy VOR presetting that leads to image stabilization, perhaps together with a decrease of possible misjudgments.
