Gaze information is obtained during Web usability evaluation - plotting the gaze locus and estimating the gaze duration for an image on a Web page. However, the one at the position of the gaze had to specify and to specify something by the evaluator. Therefore, considerable of time is required for analysis. The proposed tool can automatically identify what an observer is viewing. Thus, using the proposed gaze analysis tool, gaze information, which was earlier analyzed qualitatively, can be analyzed quantitatively. © 2011 Springer-Verlag.
