Updated 12-22-03 BSL PRO Lesson H15: Electrooculography (EOG): Ocular Fixations While Viewing an Image Derived from original work created by Pr Jean-François Lambert and Nicole Chantrier, Institut d'Enseignement à Distance / Université Paris 8- Saint-Denis France Overview Translated from original work created by Pr Jean-François Lambert and Nicole Chantrier, Institut d'Enseignement à Distancez / Université Paris 8- Saint-Denis France Electrooculography (EOG) is the electric transduction of combined eye movement. Without moving the head, a variety of horizontal and vertical eye movements encompass a visual field in which you can explore an image, utilizing spontaneous tendencies of gaze during conversations or reading. Sometimes, analysis of spontaneous gaze tendencies can indicate the attitude of a subject. For example, spontaneous movements towards the left are usually under control of the right hemisphere, which is generally associated with negative emotions. Objectives 1. To record spontaneous gaze changes produced when viewing an image. 2. To correlate results from an EOG plot with a subject's attitude or level of interest. Equipment BIOPAC electrode lead set (SS2L) (two per subject) BIOPAC disposable vinyl electrodes (EL503) (six per subject) Electrode gel (GEL1) and abrasive pad (ELPAD) Blank Paper (at least 8.5" x 11") Images (such as magazine advertisements) Computer running Windows XP or Mac OS X
