PowerPoint is the most widely used media in instruction and the illustration is an important component of PPT. Well-designed illustrations could attract student's attention and enhance learning efficiency. In this research,eye tracking system is used to record the eye movement indexes of college students when they are reading PowerPoint with different illustration colors and layouts. The results show that the related eye movement indexes of the color illustration are significantly better than the black-white illustration. However,no significant difference was founded in the test scores, indicating the color only enhanced the motivation of the subjects. The location( up,down,left, right) of illustration influenced the eye movement indexes of the subjects. The eye-tracking data shows the students have some attention preferences. According to the experiment result,advices are given for better design of educational PowerPoint.
