Our aim is to evaluate the relationship between the mechanism of processing visual information and eye movement. To examine the characteristics of the acquisition of visual information at a fixation point, eye movement was analyzed while the subjects counted circles embedded in distractors. In our new approach, distractors that were included within a certain area around the fixation point were changed to circles, immediately after the subjects fixated on them. As a result, fixation duration of 100 - 150 ms was required to correctly count circles, before the distractors of the fixated area of 6.7 degrees were changes to attractors.
