2次元顔画像に対する異なる印象判断時の眼球運動比較: 停留点と停留時間の分析

摘要

We investigated whether different features in the face image are gazed at while making impression judgments in different personality traits. Pairs of synthesized face images, both of which were generated by averaging the faces of different age groups, were sequentially presented at normalized positions. For each pair of faces, subjects decided which one was more extreme with respect to either of the traits in question (i.e., seniority and sociability), while their eye movements were measured by a rapid eye-movement measurement system. The eye-movement results were represented in 2D histograms to indicate the spatial distribution of the cumulative duration of the gaze at each fixation point; positions corresponding to the mode of each histogram were analyzed by ANOVA. The results suggest that attention is drawn to different features in impression judgments.%2種類の印象判断課題(社交性比較判断、老若判断)時の眼球運動を計測する.顔画像上の各領域の「累積停留時間ヒストグラム」を基に，顔画像観測時の停留点と停留時間について総合的に比較することで，顔のどこを見て印象判断しているのか，また印象判断課題内容によって利用する特徴や知覚方略が異なっている可能性について明らかにする.
