This paper describes an experimental study which utilised eye gaze tracking as a method for usability evaluation of web sites. There were 39 participants involved in this experiment; each participant visited the same three web sites from three categories (information, entertainment, e-commerce) and completed given use scenarios. All par- ticipants' eye gaze patterns were recorded automatically with the remote eye gaze track ing equipment called faceLAB. The following measures were investigated and com- pared across three web sites: average fixation duration, cumulative fixation time, num- ber of fixations, and average PERCLOS. It was found that some of the measures were different across web sites. Average fixation duration, in particular, was found to be different in two out of the three comparisons.
