ABSTRACT
Precise control of eye movements is crucial for accurate perception of the outside world. Eye movements enable the visual system to acquire information by scanning relevant aspects of the environment. Object recognition, discrimination, and other information intake by the visual system are accomplished mostly through unconscious scanning eye movements. The major part of processing the new information takes place when the eyes make brief pauses. The process of measuring eye movements in different environmental contexts is called electrooculography (EOG). The EOG technique is concerned with measuring changes in electrical potential that occur when the eyes move. The EOG has been useful in a wide range of applications from the rapid eye movements measured in sleep studies to the recording of visual fixations during normal perception, visual search, perceptual illusions, and in psychopathology. Studies of reading, eye movements during real and simulated car driving, radar scanning, and reading instrument dials under vibrating conditions have been some of the practical tasks examined with eye movement recordings.
