エージェントの表情変化により生起する力覚の評価

抄録

This paper presents an experiment to demonstrate that social stimulus (changes in facial expressions) can generate haptic sensations in a human-agent interactions setting. We designed and developed a system in which an human-like agent on the display behaved as if it pulled the mouse cursor against a human participant control. The results of the experiment showed that participants felt significantly larger force when the agent exhibited the negative face during the pulling motion than that when the agents kept the positive face. Besides, the force sensations quantified with control-display ratio negatively correlated with some of sub-scales of the Autism-spectrum Quotient score. This indicates that the social stimulus is as important as physical stimulus when designers and researchers design human-agent haptic interactions.
