Video-oculography examination in progress. Video-oculography (VOG) is a non-invasive, video-based method of measuring horizontal, vertical and torsional position components of the movements of both eyes (eye tracking) using a head-mounted mask that is equipped with small cameras. VOG is usually employed for medical purposes.
Eye tracking on the International Space Station. The eye-tracking device (ETD) is a headmounted device, designed for measurement of 3D eye and head movements under experimental and natural conditions. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and optionally head movement (six degrees of freedom).
Scientists track eye movements in glaucoma patients to check vision impairment while driving. Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the ...
Virtual reality headset. A virtual reality headset (or VR headset) is a head-mounted device that uses 3D near-eye displays and positional tracking to provide a virtual reality environment for the user. VR headsets are widely used with VR video games, but they are also used in other applications, including simulators and trainers.
The Integrated Helmet and Display Sight System (IHADSS) 30 mm M230 chain gun turret on a Boeing AH-64 Apache being aimed with a helmet-mounted sight. A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes. [1][2][3] It provides visual information to the user where head ...
Oculometer. Oculometer is a device that tracks eye movement. [1] [2] The oculometer computes eye movement by tracking corneal reflection relative to the center of the pupil. [3] An oculometer, which can provide continuous measurements in real time, can be a research tool to understand gaze as well as cognitive function.
Head-mounted display. A head-mounted display (HMD) is a display device, worn on the head or as part of a helmet (see helmet-mounted display for aviation applications), that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). HMDs have many uses including gaming, aviation, engineering, and medicine.
SensoMotoric Instruments (SMI)[1] was a German provider of dedicated computer vision applications with a major focus on eye-tracking technology. SMI was founded in 1991 as a spin-off from academic and medical research at the Free University of Berlin. The company has its headquarters in Teltow near Berlin, Germany, offices in Boston ...
