ELECTROOCULOGRAPHY SEMINAR REPORT PDF

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 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. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically the movement of the retina. 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.

Latest Seminar Topics for Engineering Students. Scientists use this method to help disabled individuals control wheelchairs, help them operate computers etc. Similarly a downward movement of the eyes will give a similar voltage with opposite polarities to that obtained due to the left movement.

Enucleation of the eye. 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.

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. Hello Haritha, Electroculography to Collegelib! Electrooculography Seminar Report, Abstract. By using this site, you agree to the Terms of Use and Privacy Policy. 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.

In other projects Wikimedia Commons. Positive or negative pulses will be generated when the eyes rolling upward or downward. 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. Electromyography Facial electromyography Nerve conduction study. Are you interested in this topic.

Electro-occulograph can be used in ophthalmology for diagnosis and prognosis of several eye ailments. Eye movement research is of great interest in the study of neuroscience. Electrooculography, in addition to other neuromuscular signals, is used as a computer input method by electrooculogrqphy Neural Impulse Actuator.

The result was an improvement over the technique used for the film The Polar Express. In the process of detection, the electrodes act as a transducer converting the ion current obtained at the skin to electron current. Please help improve this section by adding citations to reliable sources. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically the movement of the retina.

In practice, the measurement is similar to eye movement recordings see above. Due to the movement of the retina, there will be a difference in the electrodes. Resting potential refers to the difference between two points in the retina from its center position.

Consequently, a potential difference occurs between the electrodes. The advantage of EOG eye gaze interface is its simple configuration: Unsourced material may be challenged and reort. We prepared and electrooculograpuy this seminar abstract for final year engineering students seminar research. The EOG is one of the very few methods of recording eye movements that does not require a direct attachment to the eye itself.

Please refer to our Seminar PPT preparation guide for a better quality seminar. Electrooculography There might be a discussion about this on the talk page. This section does not cite any sources. Seamless sensing and context-awareness in everyday environmentsJournal of Ambient Intelligence and Smart Environments, 1 2: Electro-occulography is recording technique that allows the standing potential between the cornea and the posterior pole of the eye tube recorded.

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.

For this reason, it is possible to detect eye movement with the appropriate placement of electrodes on the skin surrounding the eyes. TOP Related Posts.

The eye is a complex optical system which collects light from the surrounding environment, regulates its intensity and focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain. The new advancements in the field of biomedical electronics and in the field of electronics and communication system have changed the perception of eye from an ordinary sense organ which enables us to see , in to, an organ which generates trigger pulses to activate and control various electronic devices. The new methods of efficient human machine interfaces by using the eye movements and eye blinks are realized by using a very new bio-electric signal processing technique called as Electrooculography EOG. Electrooculography is a technique for measuring the resting and action potential of the retina. The resulting signal is called the electrooculogram.

Nekasa 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. 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. Subscribe via email for more Latest topics 12 Steps to boost your innovative project ideas The best Seminar Topics for Semunarbig list with abstracts Previous year, collection of ECE Seminar topics with abstracts 2 harithaveluri 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 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.
