@inproceedings{17248, abstract = {{Gesture is an important feature of social interaction, frequently used by human speakers to illustrate what speech alone cannot provide, e.g. in order to convey referential, spatial or iconic information. Accordingly, humanoid robots that are intended to engage in natural human-robot interaction should produce speech-accompanying gestures for comprehensible and believable behavior. But how does a robot's non-verbal behavior influence human evaluation of communication quality and the robot itself? To address this research question we conducted two experimental studies. Using the Honda humanoid robot we investigated how humans perceive various gestural patterns performed by the robot as they interact in a situational context. Our findings suggest that the robot is evaluated more positively when non-verbal behaviors such as hand and arm gestures are displayed along with speech. These findings were found to be enhanced when the participants were explicitly requested to direct their attention towards the robot during the interaction.}}, author = {{Salem, Maha and Rohlfing, Katharina and Kopp, Stefan and Joublin, Frank}}, booktitle = {{Proceedings of the 20th IEEE International Symposium on Robot and Human Interactive Communication}}, pages = {{247--252}}, title = {{{A Friendly Gesture: Investigating the Effect of Multi-Modal Robot Behavior in Human-Robot Interaction}}}, doi = {{10.1109/roman.2011.6005285}}, year = {{2011}}, } @article{17246, author = {{Nomikou, Iris and Rohlfing, Katharina}}, issn = {{1943-0612}}, journal = {{IEEE Transactions on Autonomous Mental Development}}, keywords = {{acoustic packaging, mother-child interaction, social learning, multimodal grounding in input, ecology of interactions, synchrony}}, number = {{2}}, pages = {{113--128}}, publisher = {{Institute of Electrical & Electronics Engineers (IEEE)}}, title = {{{Language Does Something: Body Action and Language in Maternal Input to Three-Month-Olds}}}, doi = {{10.1109/TAMD.2011.2140113}}, volume = {{3}}, year = {{2011}}, } @inproceedings{17237, author = {{Salem, M. and Eyssel, Friederike Anne and Rohlfing, Katharina and Kopp, K. and Joublin, F.}}, booktitle = {{Social Robotics.}}, editor = {{Multu, B. and Bartneck, C. and Ham, J. and Evers, V. and Kanda, T.}}, publisher = {{Springer}}, title = {{{Effects of humanlike conversational behaviour on perception of psychological antropomorphism: A case study with a humanoid robot}}}, volume = {{7072}}, year = {{2011}}, } @article{17249, author = {{Nachtigäller, Kerstin and Rohlfing, Katharina}}, issn = {{0049-8653}}, journal = {{Zeitschrift für Literaturwissenschaft und Linguistik}}, pages = {{139--155}}, publisher = {{Metzler}}, title = {{{Einfluss von erlebten und vorgestellten Ereignissen auf die Erzählweise in kindgerichteter Sprache}}}, volume = {{162}}, year = {{2011}}, } @article{17247, author = {{Rohlfing, Katharina}}, issn = {{1574-9630}}, journal = {{Dialogue & Discourse}}, pages = {{1--18}}, publisher = {{Rodopi}}, title = {{{Exploring „Associative talk“ in German mother-child task-oriented discourse}}}, volume = {{2}}, year = {{2011}}, } @inproceedings{17235, author = {{Nomikou, Iris and Rohlfing, Katharina}}, title = {{{The role of intermodal synchrony in maternal input to 3-month-olds: A naturalistic study with special focus on the interplay between language and action.}}}, year = {{2011}}, } @inproceedings{17234, author = {{Fischer, Silke and Schulze, Denis and Borggrebe, Pia and Piefke, Martina and Wachsmuth, Sven and Rohlfing, Katharina}}, title = {{{Multi-Modal Anchoring in Infants and Artificial Systems}}}, year = {{2011}}, } @article{41260, author = {{Bauer, Matthias and Stalinski, Tom and Aziz, Emad F.}}, issn = {{1439-4235}}, journal = {{ChemPhysChem}}, keywords = {{Physical and Theoretical Chemistry, Atomic and Molecular Physics, and Optics}}, number = {{11}}, pages = {{2088--2091}}, publisher = {{Wiley}}, title = {{{Insights into the Induced Ultrafast Electron Delocalization in Fe(CO)5 Using Dark Channel Fluorescence Yield X-Ray Absorption}}}, doi = {{10.1002/cphc.201100243}}, volume = {{12}}, year = {{2011}}, } @inproceedings{17430, abstract = {{Previous work has shown that gestural behaviors affect anthropomorphic inferences about artificial communicators such as virtual agents.
