In this study, an experiment was conducted in Arakawa, Tokyo wherein three groups of people, namely Japanese residents, Japanese visitors, and non-Japanese visitors, wore an eye tracker and walked along a conventional Japanese shopping mall. Visual fixation points were measured with respect to a two -dimensional (2D) orthogonal relative coordinate system of the eye tracker screen. A method was developed for mapping these 2D data into a three-dimensional (3D) polar absolute coordinate system, and the fixation point distributions in 3D space were thereby obtained. The fixation time distributions and the associated visual objects were also determined. Gaze behaviors of the three groups were subsequently analyzed and compared. Furthermore, subconscious visual attention while walking in the town was quantitatively characterized according to the social backgrounds of the people.
