In this paper, we showed clearly that web usability problems are reflected in gazing point data by an experiment. In the experiment, firstly, gazing points data of a subject's browsing are recorded. Secondly, we collected usability problems in web pages. Subjects checked web pages based on recorded data using a checklist and evaluators interviewed subjects about usability problems in web pages. We classified the browsed pages and usability problems based on gazing point movement speed and length. An experimental result showed that the tendency of usability problems appears gazing point movement speed. Moreover, the size of usability problems appears gazing point movement length. The possibility of the usability evaluation using quantitative eyes data was shown from the experimental result. Therefore, the quantitative and objective usability evaluation, which does not need the special knowledge about usability, is possible.
