ITACO: Constructing an emotional relationship between human and robot

In this paper we describe an ITACO system that is able to construct an emotional relationship between humans and interactive systems by a migratable agent. The agent in the ITACO system can migrate between interactive systems within an environment. We conducted psychological experiments to verify whether the ITACO system can construct an emotional relationship between humans and interactive systems such as a robot and a table lamp. The experimental results show that emotional relationships were constructed between humans and interactive systems. Thus emotional relationships gave an influence to human’s behavior and cognitive abilities.
