An assembly of mains electricity (AC-powered) devices designed to measure, evaluate and record the movement of the eyes. The device is intended to measure ocular dynamics, typically measuring both horizontal and vertical eye movements. This device can include a stimulus source (e.g., a light bar), a sensing device (e.g., video or infrared cameras), a computer, and a recorder. Some systems may include cameras and/or eyelid trackers mounted on spectacles or headbands.
