  • Walters, Michael L.; Syrdal, Dag S.; Dautenhahn, Kerstin; te Boekhorst, René; Koay, Kheng Lee (2008): Avoiding the uncanny valley. Robot appearance, personality and consistency of behavior in an attention-seeking home scenario for a robot companion. In: Autonomous Robots 24 (2), S. 159-178. DOI: 10.1007/s10514-007-9058-3

    Abstract: This article presents the results of video-based Human Robot Interaction (HRI) trials which investigated people's perceptions of different robot appearances and associated attention-seeking features and behaviors displayed by robots with different appearance and behaviors. The HRI trials studied the participants' preferences for various features of robot appearance and behavior, as well as their personality attributions towards the robots compared to their own personalities. Overall, participants tended to prefer robots with more human-like appearance and attributes. However, systematic individual differences in the dynamic appearance ratings are not consistent with a universal effect. Introverts and participants with lower emotional stability tended to prefer the mechanical looking appearance to a greater degree than other participants. It is also shown that it is possible to rate individual elements of a particular robot's behavior and then assess the contribution, or otherwise, of that element to the overall perception of the robot by people. Relating participants' dynamic appearance ratings of individual robots to independent static appearance ratings provided evidence that could be taken to support a portion of the left hand side of Mori's theoretically proposed 'uncanny valley' diagram. Suggestions for future work are outlined.

    Abstract: There has been growing interest in both developing and implementing service robots for health care and home environments. In addition to a variety of functions supported by robotic technology, the interaction between a human and robot, including human emotional experiences, can affect perceived service quality and satisfaction. Based on a survey of existing service robot applications and associated interface requirements, we consider anthropomorphism as a critical characteristic of the robot interface. We propose a preliminary research framework to support identification of the exact relationship between robot interface features and user (emotional) responses in service contexts. Future experimental investigations based on the framework are to be conducted.
