Abstract

This research investigated the effect of avatar's facial expression function on users' motivation for engaging in conversation and understanding a partner's emotion in online chat communication and attempted to improve the chat system based on the usability ratings of that function. In Experiment 1, 15 pairs of university students chatted in English using both the smiley-based and the non-facial expression systems and evaluated their usability. Results showed that the smiley-based system was not found to be superior to the non-facial expression system. Based on those results, the smiley-based system was modified into an icon-based system to improve its usability. In Experiment 2, 16 pairs of students chatted in Japanese using both the icon-based and the non-facial expression systems and guessed their partner's emotional states during the chat. Participants found it easier to guess their partner's emotions when using the facial expression system. The outcomes and limitations of the experiments for future research were discussed.
