We investigated the effects of using immersive virtual humans to teach users social conversational verbal and non-verbal protocols in south Indian culture. The study was conducted using a between-subjects experimental design, and compared instruction and interactive feedback from immersive virtual humans against instruction based on a written study guide with illustrations of the social protocols. Participants were then tested on how well they learned the social conversational protocols by exercising the social conventions in front of videos of real people. The results of our study suggest that participants who trained with the virtual humans performed significantly better than the participants who studied from literature.
