Video & EOG based investigation of pure saccades in human subjects

Abstract

Human Computer Interaction (HCI) is the methodology through which computing systems understand actions of human beings. Some important applications of HCI as reported in literature are eye gaze estimation, eye tracking, alertness and health monitoring etc. Of them major applications are based upon eye movements. However, accurate estimation of these measurements is still a challenge in research community. A particular type of eye movement i.e. saccadic eye movement has potential applications in HCI such as alertness assessment, disease diagnosis etc. Electrooculography (EOG) based measurement of saccadic movements has been reported to be an accurate method. However being a contact based method, alternative method as suggested by literature is image based approach. This paper aims to investigate the correlation between video and EOG based observation of pure horizontal directional saccades to establish a relationship between image and EOG signals.
