Abstract
A head-mounted device may have a head-mounted housing. The head-mounted housing may have displays that overlap a user's eyes and/or speakers that provide sound to the user's ears. The head-mounted housing may have transparent lenses that overlap the eyes of the user or may have opaque structures that prevent ambient light from reaching the user's eyes. The head-mounted device may have a geographic location sensor such as a satellite navigation system sensor and may include an orientation sensor such as an inertial measurement unit. The direction of a user's gaze relative to the head mounted device may be measured using an electrooculographic sensor. Electrodes in the electrooculographic sensor may measure signals resulting from the standing potential between the retina and cornea in the eye. Facial expressions and eye blinks may affect the signals detected with the electrodes and can be monitored during operation.
