"Can you answer questions, Flobi?": Interactionally defining a robot’s competence as a fitness instructor

Süssenbach L, Pitsch K, Berger I, Riether N, Kummert F. "Can you answer questions, Flobi?": Interactionally defining a robot’s competence as a fitness instructor. In: Proceedings of the 21th IEEE International Symposium in Robot and Human Interactive Communication (RO-MAN 2012). 2012.Users draw on four sources to judge a robot’s competence: (1) the robot’s voice, (2) physical appearance of and (3) the interaction experience with the robot but also (4) the relationship between the robot’s physical appearance and its conduct. Furthermore, most approaches in social robotics have an outcome-oriented focus and thus use questionnaires to measure a global evaluation of the robot after interaction took place. The present research takes a process-oriented approach to explore the factors relevant in the formation of users’ attitudes toward the robot. To do so, an ethnographic approach (Conversation Analysis) was employed to analyze the micro-coordination between user and robot. We report initial findings from a study in which a robot took the role of a fitness instructor. Our results emphasize that the participant judges step-by-step the robot’s capabilities and differentiates its competence on two levels regarding to the robot’s role: a robot as a (1) social/interactional co-participant and as a (2) fitness instructor

How Specific Is Source Memory for Faces of Cheaters? Evidence for Categorical Emotional Tagging

Two experiments designed to examine the specificity of emotional source memory are reported. In the encoding phase, participants saw faces along with emotional context information, that is, descriptions of cheating, trustworthy, or irrelevant behavior. In the test phase, participants were required to complete a source classification test and a cued recall test. In both experiments, the source memory advantage for faces characterized by negative context information (cheating) was replicated. Extending previous research, a multinomial source-monitoring model was applied to distinguish between specific source memory for individual behavior descriptions and partial source memory in the sense of only a rough classification of the behavior as belonging to a particular emotional category-cheating, trustworthy, or neither of these. The results indicate that the source memory advantage for the emotional context information is not always accompanied by enhanced recollection of the specific details of the learning episode and might rather reflect unspecific memory for categorical emotional information

Talking with Robots about Objects: A system-level evaluation in HRI

Peltason J, Riether N, Wrede B, Lütkebohle I. Talking with Robots about Objects: A system-level evaluation in HRI. In: 7th ACM/IEEE Conference on Human-Robot-Interaction. 2012.We present the design process, realization and evaluation of a robot system for interactive object learning. The system-oriented evaluation, in particular, addresses an open problem for the evaluation of systems, where overall user satisfcation depends not only on the performance of the parts, but also on their combination, and on user behavior. Based on the PARADISE method known from spoken dialog systems, we have defined and applied internal and external metrics for fine-grained and largely automatable identification of such relationships. Through evaluation with n=28 subjects, indicator functions explaining up to 55% of variation in several satisfaction metrics were found. Furthermore, we demonstrate that the system’s interaction style reduces the need for instruction and successfully recovers partial failures
