| Abstract(in English) | The time required to identify a word is shortest when eyes fixate near the center of the word. This phenomenon has been called Optimal Viewing Position effect. The fixation duration is longest when eyes fixate near the center of a word in contrast to the time required to identify the word. This phenomenon has been called Inverted Optimal Viewing Position effect. Eye tracker equipments can't record short saccades. In fact, when some fixations are performed successively in a narrow area, eye tracker equipments record only one fixation. Therefore, the fixation duration recorded by eye tracker equipments is equal to the sum of the time spent on fixations and the time required to take some saccades performed in a narrow area. In this paper, we realize eye movements on the computer and examine fixation duration in two cases that a fixation is defined as fixations performed in a narrow area and that a fixation is defined as the fixation only. We indicate that Inverted Optimal Viewing Position effect appears on eye movements in the case that a fixation is defined as some fixations performed in a narrow area. |
