A Case Study of Service Robot Interaction Design according to Purpose of Use: focusing on Feedback

Abstract

Recently, the development of service robots that can assist or replace human work is accelerating by utilizing technological advances such as artificial intelligence and autonomous driving. Through this, the size of the global service robot market is increasing, and it is expected that the contact point between humans and robots will increase in real life according to these changes. Therefore, research on human-robot interaction (HRI) for smooth communication is a meaningful research topic. This study examined various interaction cases of foreign and domestic service robots. The human-likeness of the robot was derived as an evaluation factor, and the service robot was classified into functional and relational types according to the role of the robot, and it was analyzed by comparing the utilization of interaction feedback. As a result, relational service robots have higher utilization of interaction feedback in visual appearance, touch, movement, interaction behavior, and non-verbal communication than functional service robots. In the case of sound interaction, it was highly utilized regardless of relationship type and functional type, and the interaction between verbal communication and social behavior was highly utilized for functional service robots. Through this study, it is expected that a meaningful direction can be presented by helping to supplement and improve the interaction of many service robots to be developed in the future.
