Physiological Responses on Greeting with Robot under Difference of Culture

Abstract

In this study, authors suggested the system which considered difference of culture through the language and gesture movement in the interaction with a robot when user greets. In the interaction, verbal and nonverbal information are important to do natural communication. Authors focused on not only languages but also gesture movement which varies from cultures. It is necessary for even communication between a human and a robot to take in the difference of culture. Authors’ experiment shows that whether this greeting difference leads to changes or not in the human biological signal. The human biological signals are estimated by pulse wave obtained from a finger and brain blood flow measured by NIRS. The result is that biological signals will be changed when the reaction of languages and gestures changed.
