Abstract
Congruence of verbal and nonverbal behavior of a robot is essential to establish a seamless and natural interaction between humans and robots. We have investigated the preference and user experience of the senior participants that a robot approaches with expressive movement that is tailored or incongruent to the message the robot brings. Twelve elderly experienced three scenarios with different messages varying from good news, bad news, and functional news, accompanied by the corresponding approaching behavior and body posture. The user experience of these elderly was evaluated during these scenarios using a questionnaire and a semi-structured interview. The participants were interviewed about their experience, preference, and motivation for the different robot motion behaviors. The analysis showed no significant difference in user experiences in the good news and functional news scenarios. Also, no clear preference among the different robot behaviors was found. However, a significant preference for congruence in the sad news scenario was found with a clear preference for the sad approaching behavior.
