Extending Human-Robot Relationships Based in Music with Virtual Presence
IEEE Transactions on Cognitive and Developmental Systems
MetadataShow full item record
Social relationships between humans and robots require both long term engagement and a feeling of believabilty or social presence towards the robot. It is our contention that music can provide the extended engagement that other open-ended interaction studies have failed to do, also, that in combination with the engaging musical interaction, the addition of simulated social behaviours is necessary to trigger this sense of believability or social presence. Building on previous studies with our robot drummer Mortimer that show including social behaviours can increase engagement and social presence, we present the results of a longitudinal study investigating the effect of extending weekly collocated musical improvisation sessions by making Mortimer an active member of the participant’s virtual social network. Although we found the effects of extending the relationship into the virtual world were less pronounced than results we have previously found by adding social modalties to human-robot musical interaction, interesting questions are raised about the interpretation of our automated behavioural metrics across different contexts. Further, we found repeated results of increasingly uninteruppted playing and notable differences in responses to online posts by Mortimer and posts by participant’s human friends.
