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 Seminar Report, Abstract

In the process of detection, the electrodes act as a transducer converting the ion current obtained at the skin to electron current. This technology is based on the principle of recording the polarization potential or corneal-retinal potential CRPwhich is the resting potential between the cornea and the retina.

Seamless sensing and context-awareness in everyday environmentsJournal of Ambient Intelligence and Smart Environments, 1 2: Assuming that the resting potential is constant, the feport potential is a measure of the eye’s position. During dark adaptationresting potential decreases slightly and reaches a minimum “dark trough” after several minutes. Despite the recent technological improvements, eye trackers remain very much a high cost research and academic tool requiring specially trained personnel to set-up and operate the systems.

Consequently, a potential difference occurs between the electrodes. Electrooculography Published on Nov 23, The resulting signal is called the electrooculogram.

Many experiments show that the corneal part is a positive pole and the retina part is a negative pole in the eyeball. Please help improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed.

Electro-occulography is recording technique that allows the standing potential between the cornea and the posterior pole of the eye tube recorded. The important factor regarding the EOG signal is that it does not fall in the amplitude or frequency range of the EMG signal ,thus during the process of measurement of the EOG signals ,the head or other parts of the body can be moved ,as these muscular activities will not interfere with the EOG signals and can be filtered easily.

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. This section may be confusing or unclear to readers. The EOG is one of the very few methods of recording eye movements that does not require a direct attachment to the eye itself. Similarly a downward movement of the eyes will give a similar voltage with opposite polarities to that obtained due to the left movement.

In cases of extensive brain damage, where the person is unable to communicate verbally or physically, doctors can use this method to sekinar brain activity.

Electrooculography Seminar Report, Abstract

Resting potential refers to the difference between two points in the retina from its center position. To measure, the positive and negative eeminar of the retina, Doctors make the use of electrodes. Electro-occulography is widely used in ophthalmic research and rfport laboratories because it provides the method for recording with full range of eye movements. December Learn how and when to remove this template message. An electrical field is set up in the tissues surrounding the eye and the rotation of the eye causes corresponding rotation of field vector.

When the eyes are made to move upwards, then there results an action potential, which when measured will give a value of Scientists use weminar method to help disabled individuals control wheelchairs, help them operate computers etc.

Since these positions are constant, a change in the recorded potential originates from a change in the resting potential. The derivation of the EOG is achieved placing two electrodes on the outer side of the eyes to detect horizontal movement and another pair above and below the eye to detect vertical movement.
