Move Your Wheelchair with Your Eyes
International Journal of Applied Mathematics, Advanced Technology and Science Electronics and Computers ISSN:2147-82282147-6799 www.atscience.org/IJAMEC Original Research Paper Move Your Wheelchair with Your Eyes Gökçen ÇETİNEL*1, Sevda GÜL2, Zafer TİRYAKİ3, Enes KUZU4, Meltem MİLLİGÜNEY5 Accepted : 12/05/2017 Published: 21/08/2017 DOI: 10.18100/ijamec.2017Special Issue30462 Abstract: In the proposed study, our goal is to move paralyzed people with their eyes. Otherwise, use this document as an instruction set. Paper titles should be written in uppercase and lowercase letters, not all uppercase. For this purpose, we use their Electrooculogram (EOG) signals obtained from EOG goggles completely designed by the authors. Through designed EOG goggles, vertical-horizontal eye movements and voluntary blink detection are verified by using 5 Ag-AgCl electrodes located around the eyes. EOG signals utilized to control wheelchair motion by applying signal processing techniques. The main steps of signal processing phase are pre-processing, maximum-minimum value detection and classification, respectively. At first, pre-processing step is used to amplify and smooth EOG signals. In maximum-minimum value detection we obtain maximum and minimum voltage levels of the eye movements. Furthermore, we determine the peak time of blink to distinguish voluntary blinks from involuntary blinks. Finally, at classification step k-Nearest Neighbouring (k-NN) technique is applied to separate eye movement signals from each other. Several computer simulations are performed to show the effectiveness of the proposed EOG based wheelchair control system. According to the results, proposed system can communicate paralyzed people with their wheelchair and by this way they will be able to move by their selves. -
Electroretinography 1 Electroretinography
Electroretinography 1 Electroretinography Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells. Electrodes are usually placed on the cornea and the skin near the eye, although it is possible to record the ERG from skin electrodes. During a recording, the patient's eyes are exposed to standardized stimuli and the resulting signal is displayed showing the time course of the signal's Maximal response ERG waveform from a dark adapted eye. amplitude (voltage). Signals are very small, and typically are measured in microvolts or nanovolts. The ERG is composed of electrical potentials contributed by different cell types within the retina, and the stimulus conditions (flash or pattern stimulus, whether a background light is present, and the colors of the stimulus and background) can elicit stronger response from certain components. If a flash ERG is performed on a dark-adapted eye, the response is primarily from the rod system and flash ERGs performed on a light adapted eye will reflect the activity of the cone system. To sufficiently bright flashes, the ERG will contain an A patient undergoing an electroretinogram a-wave (initial negative deflection) followed by a b-wave (positive deflection). The leading edge of the a-wave is produced by the photoreceptors, while the remainder of the wave is produced by a mixture of cells including photoreceptors, bipolar, amacrine, and Muller cells or Muller glia.[1] The pattern ERG, evoked by an alternating checkerboard stimulus, primarily reflects activity of retinal ganglion cells. -

ISSN (Print) : 2319-5940 ISSN (Online) : 2278-1021 International Journal of Advanced Research in Computer and Communication Engineering Vol. 2, Issue 11, November 2013 An Overview of “Electrooculography” Uzma Siddiqui1, A.N Shaikh2 EC Department, Savitribai Phule Women’s Engineering College, Aurangabad MH, India 1 EC Department, Savitribai Phule Women’s Engineering College, Aurangabad MH, India 2 Abstract: This paper brings out a new technology of placing electrodes on user’s forehead around the eyes to record eye movements which is called as Electrooculography (EOG. This technology is based on the principle of recording the polarization potential or corneal-retinal potential (CRP), which is the resting potential between the cornea and the retina. This potential is commonly known as electrooculogram. is a very small electrical potential that can be detected using electrodes which is linearly proportional to eye displacement. EOG serves as a means of control for allowing the handicapped, especially those with only eye-motor coordination, to live more independent lives. This is a low cost assistive system for disabled people. The total command control based on EOG permits users to guide it with a enough degree of comfort ability. Keywords:AnalogDigitalConverter(ADC),Electroencefalogram(EEG),Electromyalgy(EMG),Electrooculography (EOG), Rapid Eye Movement(REM),Slow eye movement(SEM). I. INTRODUCTION Electrooculography is a technique for measuring the resting potential of the retina. The resulting signal is called the electrooculogram. An electrooculograph is a device that measures the voltage between two electrodes placed on the face of a subject so it can detect eye movement. Today the use of computers is extended to every field. -

It is not intended to be a comprehensive text on ophthalmic emergencies, but rather provide reasonable guidelines for acute management and referral. The first sections give advice on how and when to refer patients, how to deal with patients who have perviously been seen by an ophthalmologist, and contact details for the ophthalmologists who take call.

Eye Movement Analysis for Activity Recognition Using Electrooculography
IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE, - PREPRINT - 1 Eye Movement Analysis for Activity Recognition Using Electrooculography Andreas Bulling, Student Member, IEEE, Jamie A. Ward, Hans Gellersen, and Gerhard Troster,¨ Senior Member, IEEE Abstract—In this work we investigate eye movement analysis as a new sensing modality for activity recognition. Eye movement data was recorded using an electrooculography (EOG) system. We first describe and evaluate algorithms for detecting three eye movement characteristics from EOG signals - saccades, fixations, and blinks - and propose a method for assessing repetitive patterns of eye movements. We then devise 90 different features based on these characteristics and select a subset of them using minimum redundancy maximum relevance feature selection (mRMR). We validate the method using an eight participant study in an office environment using an example set of five activity classes: copying a text, reading a printed paper, taking hand-written notes, watching a video, and browsing the web. We also include periods with no specific activity (the NULL class). Using a support vector machine (SVM) classifier and person-independent (leave-one-person-out) training, we obtain an average precision of 76.1% and recall of 70.5% over all classes and participants. The work demonstrates the promise of eye-based activity recognition (EAR) and opens up discussion on the wider applicability of EAR to other activities that are difficult, or even impossible, to detect using common sensing modalities. Index Terms—Ubiquitous computing, Feature evaluation and selection, Pattern analysis, Signal processing. F 1 INTRODUCTION ties have the potential to reveal much about the activities themselves - independently of what we are looking at.
