Analysis of electrooculogram signals from students before and after exam

Abstract

Electrooculogram is record of eye movement using surface electrodes. EOG signals are analyzed in many areas using various methods. In this study, EOG signals were recorded from male and female volunteer university students before and after exam to examine capability of following visual stimulant. Volunteers followed visual test program on computer. In the meantime EOG signals were recorded simultaneously. Zero-crossings of the EOG signals were examined in order to analyze the ratio of following success. As a result, zero-crossing number that calculated from EOG signals, created significant difference in women after exam.
