In this study, the authors consider eye movement as a kind of motion skills. Firstly, this paper compares and analyzes eye movement measured from 2 categories, i.e., tennis experts and beginners. The subjects in the both categories are instructed as anticipating "inside-out shot" or "down-the-line shot" from movies of expert tennis players' forehand shot. In order to compare the eye movement between the 2 categories, we make use of a time-series of likelihood distribution from gaze points measured using an eye-tracking device in this paper. We have observed two differences between the experts and beginners as experimental results ; one is that the beginners have more tendency to follow a tennis ball even after the players' shots, and another is that the experts paid more attention to a particular part of the players' body in order to attempt to find any habit as the number of shot increases, while the beginners focused on almost the same point.
