Abstract
In this work, a MATLAB-based graphical user interface is proposed for the visual examination of several eye movements. The proposed solution is algorithm-based, which localizes the area of the eye movement, removes artifacts, and calculates the view trajectory in terms of direction and orb deviation. To compute the algorithm, a five-electrode configuration is needed. The goodness of the proposed MATLAB-based graphical user interface has been validated, at the Clinic of Child Neurology of University Hospital of Ostrava, through the EEG Wave Program, which was considered as “gold standard” test. The proposed solution can help physicians on studying cerebral diseases, or to be used for the development of human-machine interfaces useful for the improvement of the digital era that surrounds us today.
Highlights
Eye is source of electrical bio-potentials, which were first discovered by Du Bois Reymond in the previous century (1848) [1]
We propose an EOG-based graphical user interface (GUI) able to display and recognize several types of eye movements
The developed MATLAB-based GUI allows the remote analysis of the eye movements through the acquisition of four EOG signals
Summary
Eye is source of electrical bio-potentials, which were first discovered by Du Bois Reymond in the previous century (1848) [1]. It is possible to determine the values of amplitude, slope, and period of the signal, as well as the trajectory of motion, which is useful to calculate the rate of eye movement changes. If this value is less than 600 ms, the time interval corresponds to the detected eye movement.
