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.

In the process of detection, the electrodes act as a transducer converting the ion current obtained at the skin to electron current.
Electrooculography Seminar Report, Abstract
Please help us clarify the section. 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 electroocklography retina. In practice, the measurement is similar to eye movement recordings see above.
Retrieved from ” https: This method is dependent on a terminology called as Resting Potential. The doctor will then measure the center position and this difference is the measurement of the position of the eye.
Download your Reports for Electrooculography 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 computing.
The advantage of EOG eye gaze interface is its simple configuration: There might be a discussion about this on the talk page.
For this reason, it is possible to detect eye movement with the appropriate placement of electrodes on seminwr skin surrounding the eyes.
Latest Seminar Topics for Engineering Students. Electrooculography EOG is a new technology of placing electrodes on user’s forehead around the eyes to record eye movements.
Please help improve this article by adding electroocuulography to reliable sources. 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.
The EOG ranges from 0. 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. Similarly a downward movement of the eyes will give a similar voltage with opposite polarities to that obtained due to the left movement.

Eye movement research is of great interest in the study of neuroscience. When the doctor asks the patient to see one electrode, the portion of the retina facing that position is the plus side and the portion away from that electrode is the minus side.
This page was last edited on 8 Novemberat From Wikipedia, the free encyclopedia. Electrodiagnosis Eye procedures Electrophysiology Neurophysiology Neurotechnology. This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye.
We prepared and published this seminar abstract for xeminar year engineering students seminar research. The detection takes place as shown below. EOG is a very small electrical potential that can be detected using electrodes.
Seamless sensing and context-awareness in everyday environmentsJournal of Ambient Intelligence and Smart Environments, 1 2: When light is switched on, a substantial increase of electroochlography resting potential occurs “light peak”which drops off after a few minutes when the retina adapts to the light.
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.
Electrooculography EOG is a technique rsport measuring the corneo-retinal standing potential that exists between the front and the back of the human eye.
Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate erport movement, specifically the movement of the retina.
Phacoemulsification Cataract surgery Capsulorhexis. Electrooculography Seminar Report, Abstract. 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. The retina has a plus side and a minus side.
Electrooculography – Wikipedia
Resting potential refers to the difference between two points in the retina from its center position. Due to the movement of the retina, there will be a difference in the electrodes. Scientists seminat this method to help disabled individuals control wheelchairs, help them operate computers etc.
