ELECTROOCULOGRAPHY SEMINAR REPORT PDF

Electrooculography is a technique for measuring the resting and action potential of the retina. The resulting signal is called the electrooculogram. Usually, pairs. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically.

Basically EOG is a bio-electrical skin potential measured around the eyes but first we have to understand eye itself:. In cases of extensive brain damage, where the person is unable to communicate verbally or physically, doctors can use this method to track brain activity.

Electrooculography Seminar Report, Abstract

Positive or negative pulses will be generated when the eyes rolling upward or downward. Electrodiagnosis Eye procedures Electrophysiology Neurophysiology Neurotechnology. Scientists use this method to help disabled individuals control wheelchairs, help them operate computers etc.

The ratio of the voltages i. Articles needing additional references from December All articles needing additional references Articles needing additional references from November Wikipedia articles needing clarification from November All Wikipedia articles needing clarification Articles with multiple maintenance issues.

We do not prepare a PPT for your seminar, how ever we can help you providing ideas, please do your own research on the topic and prepare a seminar PPT Electrooculography. During dark adaptationresting potential decreases slightly and reaches a minimum “dark electrooculograhpy after several minutes. November Learn how and when to remove this template message. Eye movement measurement has long been an area of intense interest for researchers in a multitude of fields ranging from medicine to psychology and from advertising to reporh.

The resulting signal is called the electrooculogram.

This page was last edited on reporg Novemberat Electro-occulography is widely used in ophthalmic research and clinical laboratories because it provides the method for recording with full range of eye movements.

Not to be confused with other types electropculography electrography. Views Read Edit View history. Unlike the electroretinogramthe EOG does not measure response to individual visual stimuli. Consequently, a potential difference occurs between the electrodes.

When light is switched on, a substantial increase of the resting potential occurs “light peak”which drops off after a few minutes when the retina adapts to the light.

The amplitude of pulse will be increased with the increment of rolling angle, and the width of the positive negative pulse is proportional to the duration of the eyeball rolling process. Eye movement research is of great interest in the study of neuroscience.

In practice, the measurement is similar to eye movement recordings see above. The EOG is one of the very few methods of recording eye movements that does not require a direct attachment to the eye itself.

Seamless sensing and context-awareness in everyday environmentsJournal of Elecrrooculography Intelligence and Smart Environments, 1 2: The typical EOG waveforms generated by eye movements are shown in Fig 3. Similarly a downward movement of the eyes will give a similar voltage with opposite polarities to that obtained due to the left movement.

For other uses, see EOG disambiguation. Since eye movement can be electrooculoraphy to some degree and track by modern technology with great speed and precisionthey can now be used as a powerful input device and have many practical applications in human computer interactions.

This section may be confusing or unclear to readers. The result was an improvement over the seminarr used for the film The Polar Express.

This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye. Electrooculography Published on Nov 23, The EOG is used to assess the function of the pigment epithelium. Many experiments show that the corneal part is a positive pole and the retina electroocluography is a negative pole in the eyeball. To measure, the positive and negative points of the retina, Doctors make the use of electrodes.
