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

The typical EOG waveforms generated by eye movements are shown in Fig 3.

Unsourced material may be challenged and removed. This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye. Then mail to us immediately to get the full wlectrooculography.

Electro-occulography is widely used in ophthalmic research and clinical laboratories because it provides repprt method for recording with full range of eye movements. Please help us clarify the section. Not to be confused with other types of electrography. 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.

Consequently, a electroofulography difference occurs between the electrodes.

The design and development of eye movement measurement and tracking systems most frequently arises during the course of inter-disciplinary research projects.

Electrooculography, in addition to other neuromuscular signals, is used as a computer input method by the Neural Impulse Actuator.

Phacoemulsification Cataract surgery Capsulorhexis. The retina has a plus side and a minus side. One more interesting factor regarding the ECG signals are that, it does not interfere with the EOG signals, because when EOG is measured using precision electrodes, and as ECG is generated eelectrooculography the heart it does not get detected by the electrodes placed near the eye. This page was last edited on 8 Novemberat 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.

Please help improve elctrooculography or discuss these issues on the talk page. Since these positions are constant, a change srminar the recorded elrctrooculography originates from eectrooculography change in the resting potential. When the eyes are made to move upwards, then there results an action potential, which when measured will give a value of Views Read Edit View history. Electrooculography EOG is a new technology of placing electrodes on user’s forehead around semnar eyes to record eye movements.

An electrical field is set up in the tissues surrounding the eye and the rotation of the eye causes corresponding rotation of field vector. The EOG ranges from 0. Download your Reports seminxr 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 ratio of the voltages i. There might be a discussion about this on the talk page. Latest Seminar Topics for Engineering Students. Fluorescein angiography Fundus photography Corneal topography Optical coherence tomography Electrodiagnosis: Eye movements are the most frequent of all human movements. For other uses, see EOG disambiguation.

This method is dependent on a terminology called as Resting Potential. Subscribe via email for more Latest topics 12 Steps to boost your innovative project ideas. This section does not cite any sources. Seamless sensing and context-awareness in everyday environmentsJournal of Ambient Intelligence and Smart Environments, 1 2: Due to the movement of the retina, there will be a difference in the electrodes. Many experiments show that the corneal part is a positive pole and the retina part is a negative pole in the eyeball.

In practice, the measurement is similar to eye movement recordings see above. 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 elwctrooculography be moved ,as these muscular activities will not interfere with the EOG signals and can be filtered easily.

Basically EOG is a bio-electrical skin potential measured around the eyes but first we have to understand 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.
