Abstract
We produced the eye-tracking system using the simple infrared ray web camera. Three basic movements were tested in order to use the eye-gaze input device. First, we watched four corners of the PC display and inspected whether a pupillary central coordinate accorded with the visual line direction. Second, we displayed three lines of sentences to the PC display and detected the saccade to determine whether the sentence was read. Finally, the detection errors of fixation point were measured by viewing nine areas on the display.
