瞳孔表現メディアにおける瞳孔面積の違いに対する印象評価

抄録

Pupils are related to own affect and give favorable impressions to others depending on their size. Focusing on effects of the pupil size, various pupil sizes were evaluated using human images as stimulations in previous researches. However, it is difficult to generate extreme pupil size in human images, and the evaluation of pupil size itself is difficult because the impressions of human images are formed depending on not only pupil sizes but also other facial parts. To evaluate the impressions of the pupil size itself, it is desirable to extract only the pupil and exclude other facial parts. In this study, we analyzed the impressions on various pupil sizes that combined the dilation / contraction using two kinds of pupil expression media that have been developed. The analysis results demonstrated that a certain dilated area of pupil has a potential to form favorable impressions regardless of pupil expression media.
