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.

The design and development of eye movement measurement and tracking systems most frequently arises during the course of inter-disciplinary research projects. Since these positions electrooculogrpahy constant, a change in the recorded potential originates from a change in the resting potential.
Electrooculography – Wikipedia
The EOG is one rlectrooculography 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 Ambient Intelligence and Smart Environments, 1 2: Please help improve this article by adding citations to reliable sources. Primary applications are in ophthalmological diagnosis and in recording eye movements.

Please include ” Reference: There might be a discussion about this on the talk page. When the doctor asks the patient to see one electrode, the portion of the retina facing that position is electrooculogrraphy plus side and the portion away from that electrode is the minus side. Please help improve it or discuss these issues on the talk page.
Electro-occulography is widely used in ophthalmic research and clinical laboratories because it provides the method for recording with full range of eye movements.
Are you interested in any one of this Seminar, Project Topics. In the process of detection, the electrodes act as a transducer converting the ion current obtained at the skin to electron current.
Electrooculography was used by Robert Zemeckis and Jerome Chenthe visual effects supervisor in the movie Beowulfto enhance the performance capture by xeminar animating the eye movements of the actors.
Electro-occulography is recording technique that allows the standing potential between the cornea and the posterior pole of the eye tube recorded.
Eye movements are the most frequent of all human movements. Please help improve this section by adding citations to reliable sources. When the eyes are stationary or when the eyes are looking straight ahead, there is no considerable change in potential and the amplitude of signal obtained is approximately zero.
One more interesting factor regarding the Electroiculography signals are that, it does not interfere with the EOG signals, because when EOG is measured using precision electrodes, and as ECG is generated by the heart it does not get detected by the electrodes placed near the eye.
Enucleation of the eye. Teport typical EOG waveforms generated by eye movements are shown in Fig 3. This page was last edited on 8 Novemberat For other uses, see EOG disambiguation. We prepared and published this seminar abstract for final year engineering students seminar research.
This article needs additional citations for verification. 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.
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. Positive or negative pulses will be generated when the eyes rolling upward or downward.

Electrooculography Seminar Report, Abstract
If the eye moves from center position toward one of the two electrodes, this electrode “sees” the positive side of the retina and the opposite electrode “sees” the negative side of the retina. Then mail to us immediately to get the full report. Download your Reports for Electrooculography Eye movement measurement has long been an area of intense interest teport researchers in a multitude of fields ranging from medicine to psychology and from advertising to computing.
Not to be confused with other types of electrography.
Latest Seminar Topics for Engineering Students. You should do your own research additional to this information before presenting your seminar. An electrical field is set up in the tissues surrounding the eye and the rotation of the eye causes corresponding rotation of field vector.
Electrooculography EOG is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye.
Because this biological signal is proportional to the rotational angle of eye this technique permits a wide range of rotational angles to be recorded, allows documenting of eye movements when the eyelids are closed and unable the recording in the dark places.
Due to the movement of the retina, there will be a difference in the electrodes. This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye.
Electrooculography, in addition to other neuromuscular signals, is used as a computer input method by the Neural Impulse Actuator.
