Abstract

In this paper, we describe the brain activities that are associated with emoticons by using functional MRI (fMRI). In communication over a computer network, we use abstract faces such as computer graphics (CG) avatars and emoticons. These faces convey users' emotions and enrich their communications. In particular, when we see some abstract faces, we feel that they are more vivid and lively than photorealistic faces. However, the manner in which these faces influence the mental process is as yet unknown. In this research, we conducted an experiment by using fMRI for the most abstract faces?emoticons. The experimental results show that emoticons convey emotions without the cognition of faces. This result is very important in order to promote an understanding of how abstract faces affect our behaviors.
