Toward Describing Human Gaits by Onomatopoeias

Abstract

Native Japanese people can distinguish gaits based on their appearances and briefly express them using various onomatopoeias to express their impressions intuitively. It is said that Japanese onomatopoeias have sound-symbolism and their phoneme is strongly related to the impression of a motion. Thus, we considered that if a phonetic space based on sound-symbolism can be associated with the kinetic feature space of gaits, subtle difference of gaits could be expressed as difference in phoneme. This framework is expected to make human-computer interaction more intuitive. In this paper, we propose a method to convert the relative body-parts movements to onomatopoeias using a deeplearning based regression model. Through experiments, we confirmed the effectiveness of the proposed method, and discussed the potential of describing an arbitrary gait by not only existing onomatopoeias but also a novel one.
