INTERPRETATION OF EOG DATA IN ORDER TO OBSERVE EYE MOVEMENTS

摘要

This paper deals with the possibilities of observing eye movements from EOG recordings. First the setup for the recording of eye movements, then the EOG method, which is used to obtain eye movements in the experimental context, are explained. The first recordings resulted in the detection of eye movements within the EOG data and the results were put into relation to the gaze points gained from the eye tracking system. In addition to these subjective observations a first attempt at quantification of the dependency between EOG signal and gaze points is presented. Though faced with a few problems, it was possible to put numerical values for distances in relation to signal amplitudes of the EOG.
