A study on eye fixation time distribution with and without subjective evaluation of food and related pictures

In order to clarify the relationship between eye movements and subjective evaluation, pictures of cake, sushi, bottle with and without label were evaluated by 3-grade scale with opinions, “Like”, “Neither like nor dislike”, and “Dislike” (Task A), and looked without evaluation (Task B). Eye fixation time of each task was measured, and eye fixation time distributions were discussed. In result of Task A, the percent of frequency of eye fixation in the range from 250 to 350 ms in the “Like” case was larger than that of the “Dislike” case. And comparing of results of Task A and B, a difference between diffusive search and specific search was small.
