OVERVIEW |
EYE MOVEMENT
Eye tracking is a technique for measuring natural eye movement. Different areas of the brain are involved in producing these movements, and abnormalities that occur can be linked to dysfunction in certain areas. As a result, measuring the physical parameters of eye movements (such as latency and speed) can provide: - diagnostic indicators for functional exploration, for health professionals (such as neurologists, psychiatrists and ophthalmologists); - keys to understanding brain function, for researchers. Using oculomotor tests to target certain brain structures, it is now possible to study eye movement with greater precision. Results obtained from these tests can help determine whether a disorder is supranuclear, nuclear or infranuclear in nature (for more information, see www.EyeBrainPedia.com). OCULOMOTOR MEASUREMENT, OR EYE TRACKING Eye movement measurement (or oculomotor measurement, or eye tracking) is performed using a video eye tracker. This device uses a camera to record eye movements which are then processed by an analysis application. The program extracts relevant information regarding eye movement parameters. The resulting data can be compared with normal readings, revealing abnormalities associated with certain diseases.
e(ye)BRAIN has developed a video-oculography technique which is user-friendly, non-invasive, fast, sensitive, and conducive to automatic supervised analysis of recorded results. |
