Designing Interactions for Artificial Commensal Companions

Eating with others offers several health and social benefits, which could potentially be preserved through the use of robotic companions when dining with another person is not an option. This study examined enjoyment of interaction, social connection, desired features, and concerns regarding a lunchtime commensal interaction between a human and a social robot. Participants were asked to eat lunch, unexpectedly accompanied by a NAO robot capable of conversing with them, and to participate in a qualitative study afterward. Twenty-two users took part in interviews focused on their experience with a robot and their thoughts on the ideal functionalities an artificial commensal companion should have. Users unanimously enjoyed the interaction, and stated that they would prefer eating with a robot to eating alone. They also suggested novel applications and specific improvements, including stronger personalization and the ability to discuss personal topics and interests as well as show empathy.
