Room for one more? - Introducing Artificial Commensal Companions

Abstract

Commensality is defined as "a social group that eats together" and eating in a commensality setting has a number of positive effects on humans. In this paper, we discuss how HCI and technology in general can be exploited to replicate the benefits of commensality for people who choose or are forced to eat alone. We discuss research into and the design of Artificial Commensal Companions that can provide social interactions during food consumption. We present the design of a system, consisting of a toy robot, computer vision tracking, and a simple interaction model, that can show non-verbal social behaviors to influence a user's food choice. Finally, we discuss future studies and applications of this system, and provide suggestions for future research into Artificial Commensal Companions.
