Electrooculography (EOG) is a technique for detecting electrical signals from the extra-ocular muscles. The EOG precise method quantifying eye movements, including drowsiness-induced closure, and also promising technology its potential use as contributing mechanism brain–computer interface applications. Despite fact that change humans move their eyes, it still difficult to monitor movement patt...

The ability of an intelligent system to recognize the user’s emotional and mental states is of considerable interest for human-robot interaction and human-machine interfaces. This paper describes an automatic recognizer of the facial expression around the eyes and forehead based on electrooculographic (EOG) signals. Six movements of the eyes, namely, up, down, right, left , blink and frown, are...

The aim of this study is to present electrooculogram signals that can be used for human computer interface efficiently. Establishing an efficient alternative channel for communication without overt speech and hand movements is important to increase the quality of life for patients suffering from Amyotrophic Lateral Sclerosis or other illnesses that prevent correct limb and facial muscular respo...

Let RT (n), ED(n) and EOG(n) be the number of labelled regular tournaments, labelled loop-free simple Eulerian digraphs, and labelled Eulerian oriented simple graphs, respectively, on n vertices. Then, as n →∞, RT (n) = (2n+1 πn )(n−1)/2 n1/2e−1/2 ( 1 + O(n−1/2+ ) ) (n odd), ED(n) = ( 4 πn )(n−1)/2 n1/2e−1/4 ( 1 + O(n−1/2+ ) ) , and EOG(n) = (3n+1 4πn )(n−1)/2 n1/2e−3/8 ( 1 + O(n−1/2+ ) ) , for...

This paper presents a new method to control and guide mobile robots. In this case, to send different commands we have used electrooculography (EOG) techniques, so that, control is made by means of the ocular position (eye displacement into its orbit). A neural network is used to identify the inverse eye model, therefore the saccadic eye movements can be detected and know where user is looking. ...

The manuscript proposes and evaluates a real-time algorithm for estimating eye gaze angle based solely on single-channel electrooculography (EOG), which can be obtained directly from the ear canal using conductive ear moulds. In contrast to conventional high-pass filtering, we used an algorithm that calculates absolute eye gaze angle via statistical analysis of detected saccades. The estimated ...

Background. To report a case of acute zonal occult outer retinopathy (AZOOR) with atypical electrophysiology findings. Case Presentation. A 23-year-old-female presented with visual acuity deterioration in her right eye accompanied by photopsia bilaterally. Corrected distance visual acuity at presentation was 20/50 in the right eye and 20/20 in the left eye. Fundus examination was unremarkable. ...
