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.

Electrooculography Full Seminar Report, abstract and Presentation download
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. You should do your own research additional to this information before presenting your seminar.
Please help improve this section by adding citations to reliable sources. To measure eye movement, pairs of electrodes are typically placed either above and below the eye or to the left and right of the eye. The result was an improvement over the technique used for the film The Polar Express.
This article needs additional citations for verification.

Views Read Edit View history. 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. Seamless sensing electrooculogra;hy context-awareness in everyday environmentsJournal of Ambient Intelligence and Smart Environments, 1 2: The placement of the electrodes is up and down or right and left. Hello Haritha, Welcome to Collegelib!
Phacoemulsification Cataract surgery Capsulorhexis. 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. Please help improve this article by adding citations to reliable sources. Scientists use this method to help disabled individuals control wheelchairs, help them operate elwctrooculography etc.
Positive or negative pulses will be generated when the erport rolling upward or downward.
Because this biological signal is proportional to the electrooculoggaphy 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 semianr in the dark places. Please help improve it or discuss these issues on the talk page. 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.

The EOG is one of the very few methods of recording eye movements that does not require a direct attachment to the eye itself. Harada—Ito procedure Strabismus surgery Botulinum toxin therapy of strabismus.
The resulting signal is called the electrooculogram. The EOG is used to assess the function of the pigment epithelium. Electrooculography EOG is a new technology of placing electrodes on user’s forehead around the eyes to record eye movements. Similarly a downward movement of the eyes will give a similar voltage with opposite polarities to that obtained due to the left movement. December Learn how and when to remove this template message.

Resting potential refers to the difference between two points in the retina from its center position.
To measure, the positive and negative repoort of the retina, Doctors make the use of electrodes. Unsourced material may be challenged and removed. The important factor regarding the EOG signal is that elecyrooculography 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.
Unlike the electroretinogramthe EOG does elwctrooculography measure response to individual visual stimuli. Please refer to our Seminar PPT preparation guide for a better quality seminar. This potential is commonl y known as electrooculogram. The advantage of EOG eye gaze interface is reoprt simple configuration: As it can be seen from the above figure, four to five electrodes are required for the detection of the EOG signals. It is now accepted that the generated electrical potential arises due to the permanent potential difference 10 to 30mV that exists between the cornea and ocular fundus.
