Recently, a research on eating habits of Japanese college students revealed that they have a highly desire to communicate with others through co-eating. Even though better eating experience through co-eating is important, they often tend to be alone even more because of some reasons like small households, living alone, and having no time to find others for co-eating. Therefore, we believe that it may improve eating experience by incorporating a fictional character into the real space as a partner to eat together. For validating the idea, we have developed a virtual co-eating system for solving issues caused from solitary eating, and show some insights from its user study.
