A simple approach to detect eye movements

Eye movements are tracked mainly using electrooculography (EOG), video-oculography (VOG) and electronystagmography (ENG) for detection of nystagmus and other balance related problems. Here is a method to detect eye movements from Electroencephalography (EEG) recording. The study was started considering vertigo patients and similarity was observed in the waveform of ENG and single channel EEG recording. The signals obtained were processed and peaks were found by using first derivative. A simple aspectis built to trace the eye movements whether it is center gaze, right gaze or left gaze. Results observed were accurate when the gaze started from center gaze position. This method can also be used to track eye movements during sleep. Eye movements from beginning were ranked in order. The total time taken to display the order of eye movement was about 0.7981 sec.
