Abstract: A portable, miniaturized, lightweight ocular-vestibular testing unit with sensors in a head-mounted unit and processor and battery units either incorporated into the head-mount or on other parts of the body, such as a waist belt and connecting to one or more displays via wireless local network. A digital camera for each eye and multiple sensors are configured for ocular and vestibular system testing in a wide variety of positions and locations of a user. The unit records data from the digital cameras and sensors locally to the unit. Recorded data may be viewed via a wireless local network data connection on external displays.
