The pupil size has been studied for cognitive processing of visual information. It is known that the pupil size is primarily controlled by the physical characteristics of the visual stimulus (illuminance of viewing environment) and psychological variables (e.g. interest, memory, and emotional awakening) during observation. However, the relationship between physical and psychophysiological characteristics during observation of appearance on the object surface has not been fully investigated. In this study, we investigate how the pupil size changes when human pay attention to the material appearance such as glossiness, roughness and colorfulness. In our psychophysiological experiment, we used seven colored fabrics with the same surface texture of canvas as experimental stimuli. The participants were asked to observe the experimental stimuli according to two different observation points. During the first half, participants looked out the entire experimental stimulus idly for investigating the effect by physical characteristics of viewing environment. During the second half, they carefully observed the surface appearance of physically the same stimulus for investigating psychophysiological characteristics. As a result, the pupil size reduced during the second half. In addition, it was found that the contraction rate of the pupil size depending on the saturation of the object surface.
