Abstract: Assessing function of vestibular and oculomotor systems based on data output by a videonystagmography system and a force platform. A system includes a videonystagmography headset comprising an image sensor, wherein the image sensor outputs a video stream comprising a plurality of images of eyes of a user captured when the user wears the videonystagmography headset for a gaze test duration. The system includes a force platform comprising a load cell, wherein the force platform outputs a data stream indicating a plurality of tilt positions of the force platform captured when the user stands on the force platform for a balance test duration.
