A head-mounted device for measurement of pointing to visual targets without seeing the pointing arm.

A mobile, head-mounted device is introduced, which allows the presentation of visual targets and the measurement of pointing movements to these targets in visual open loop (i.e. blind pointing without seeing the pointing arm). This microcomputer-controlled, easy-to-operate device offers a variety of applications both in basic research and for clinical diagnosis in ophthalmology, neurology, and otolaryngology.
