Abstract
In this report, we focus on the nodding movement itself and show the results of evaluating the impressions of the various nodding movements. As a side note, we focus on three components of the nodding movement: “the depth of the nod”, “the number of nods”, and “the required time for one nod”. The impression evaluation obtained by the SD method was factor-analyzed. As the results of factor analysis, three factors were extracted: familiarity, activeness, and sincerity. And we also confirm the relationship between “three components of the nodding movement” and “three factors extracted from the results of factor analysis”. Furthermore, based on the results of evaluating the impression, various nodding movements are categorized. The results can contribute to the realization of a communication support system that is attuned to the feelings and circumstances of the user.
