The adaptation allows for a flow in communication and thereby for successful turn-taking. In contrast, when users communicate with artificial systems often reduced flow and turn-overtaking 4 are observable. The reasons for these insufficiencies may lie in the fact that little is known about the turn-taking strategies that dialogue systems should pursue 4. In our approach, we postulate that it is the feedback of the system and the interpretation of the feedback by the user that are in the center of an adaptation process As a result, one way to improve HRI, and especially its communicational flow, is to focus on different types of feedback and how they affect the user{\textquoteright} discursive behavior. In contrast to former work concentrating on telephone based speech systems or multimodal systems consisting of a touch screen and speech 1, 2, 5, we study an embodied interaction with the service robot BIRON (BIelefeld RObot CompanioN). The general goal of the studies is to develop a situated system that can learn the spatial environment as well as the names and visual appearance of objects. Therefore, BIRON can not only understand spoken speech but also co-verbal deictic references to objects in the scene and carry out mixed-initiative dialogues. In our study, the subjects were asked to introduce objects to the robot by showing and pointing. This very restricted goal allowed us to compare verbal and gestural behavior across subjects. We analyzed the interactions of 15 native German speaking users communicating with BIRON. The interaction was carried out with the fully autonomous mode of BIRON, except for the speech recognition, which was simulated by keyboard input in order to avoid speech recognition errors. By using the autonomous interaction system, we were able to produce realistic communication sequences including problems caused by the complex interaction of the diverse perceptual system components. In analyzing the users{\textquoteright} discursive behavior, we noticed different task-related interaction strategies. Focusing on subject{\textquoteright}s consistency and changes of strategies in the course of the ongoing turn-taking, we analyzed which feedback of the system caused a change of a strategy within a user. We found that subjects decided for one strategy addressing one perceptual channel (vision or speech) of the system and used it as long as they did not receive any feedback about the failure of this specific channel. We observed a change in strategy when it became obvious to the subject via feedback that a particular perceptual channel was not working appropriately. The change in strategy was likely to maintain the interaction flow and thereby the user satisfaction. While these results support previous findings indicating when and how users change strategies 1, 5, they give new insights into the discursive behavior, i.e. into the repertoire of strategies in embodied and situated interaction. The results imply that within turn-taking, users interpret the system{\textquoteright}s feedback and thus verify their model of the capabilities of the interlocutor. Thus, the change in discursive strategy is an indicator of users{\textquoteright} expectation of how the robot functions 3. In further studies we plan to deliberately vary the robots misunderstandings and integrate the personality traits of the subjects into the research on strategies.}}, author = {{Lohse, Manja and Rohlfing, Katharina and Wrede, Britta}}, booktitle = {{Presentation at the 10th International Pragmatics Conference (IPrA)}}, title = {{{Changes of users' discursive behavior in HRI}}}, year = {{2007}}, } @inproceedings{17284, abstract = {{The paper introduces an online user study onapplications for social robots with 127 participants.

Die Volksliedsammlung Des Knaben Wunderhorn 2 wurde von Achim von Arnim und Clemens Brentano ohne Notenbeigabe herausgegeben; bis ins 20. Jahrhundert reizten ihre Texte immer wieder zu Kompositionen, von denen die Wunderhorn-Lieder Gustav Mahlers heute die Bekanntesten sind.3 Die inhaltliche Heterogenität der Sammlung spiegelt sich in der Geschichte ihrer Vertonungen: Die verschiedenen Texte tragen einerseits Angebote zur kollektiven Identifikation, beispielsweise im nationalen Sinne, in sich. Gleichzeitig vermögen sie andererseits ein solches kollektives Identifikationsangebot zu durchkreuzen, indem sie das Leiden an der Außenseiterrolle — etwa in der Person eines Fahnenflüchtlings4 — thematisieren, wie in den von Gustav Mahler gewählten, zumeist von starker Gebrochenheit getragenen Liedern. Die Gestalt der Texte in der Sammlung sollte nach der Bearbeitung durch die beiden Herausgeber dem entsprechen, was sie unter „Volkston“ verstanden.5 Dieser „Ton“ der Texte wurde wiederum in der Folgezeit als verbürgter Volkston rezipiert. Er beeinflusste Dichter wie Joseph von Eichendorff, dessen Lyrik von der Wunderhorn-Sammlung inspiriert wurde.6 Das Heidelberger Jahr 1807/08, in dem dieser die Liedsammlung kennenlernte, war für Eichendorff „eines der entscheidendsten seines Lebens“.7 Die literarische Rezeption der Wunderhorn-Texte in seiner Lyrik fand wiederum ihrerseits in unzähligen Vertonungen musikalischen Widerhall, so etwa in Robert Schumanns Liederkreis op. 39.8}}, author = {{Tumat, Antje}}, booktitle = {{200 Jahre Heidelberger Romantik}}, editor = {{Strack, Friedrich}}, isbn = {{978-3-540-75233-2}}, pages = {{161‑182}}, publisher = {{Springer}}, title = {{{„In diesem Schein des Bekannten liegt das ganze Geheimniß des Volkstons“ – Die Dichtung der Heidelberger Romantik in der Musik}}}, doi = {{10.1007/978-3-540-75234-9_9}}, volume = {{51}}, year = {{2007}}, } @inbook{41632, author = {{Spiegel, Anna}}, booktitle = {{Handbuch Wissenssoziologie und Wissensforschung}}, editor = {{Schützeichel, Rainer}}, isbn = {{978-3-89669-551-2}}, keywords = {{Wissenssoziologie}}, pages = {{864}}, publisher = {{UVK-Verl.-Ges}}, title = {{{Wissen zwischen Lokalisierung und Globalisierung}}}, volume = {{15}}, year = {{2007}}, } @article{42000, author = {{Goerigk, G. and Huber, Klaus and Schweins, R.}}, issn = {{0021-9606}}, journal = {{The Journal of Chemical Physics}}, keywords = {{Physical and Theoretical Chemistry, General Physics and Astronomy}}, number = {{15}}, publisher = {{AIP Publishing}}, title = {{{Probing the extent of the Sr2+ ion condensation to anionic polyacrylate coils: A quantitative anomalous small-angle x-ray scattering study}}}, doi = {{10.1063/1.2787008}}, volume = {{127}}, year = {{2007}}, } @article{42002, author = {{Lages, Sebastian and Schweins, Ralf and Huber, Klaus}}, issn = {{1520-6106}}, journal = {{The Journal of Physical Chemistry B}}, keywords = {{Materials Chemistry, Surfaces, Coatings and Films, Physical and Theoretical Chemistry}}, number = {{35}}, pages = {{10431--10437}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Temperature-Induced Collapse of Alkaline Earth Cation−Polyacrylate Anion Complexes}}}, doi = {{10.1021/jp068258k}}, volume = {{111}}, year = {{2007}}, } @article{42006, author = {{Hermes, Stephan and Witte, Thomas and Hikov, Todor and Zacher, Denise and Bahnmüller, Stefan and Langstein, Gerhard and Huber, Klaus and Fischer, Roland A.}}, issn = {{0002-7863}}, journal = {{Journal of the American Chemical Society}}, keywords = {{Colloid and Surface Chemistry, Biochemistry, General Chemistry, Catalysis}}, number = {{17}}, pages = {{5324--5325}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Trapping Metal-Organic Framework Nanocrystals:  An in-Situ Time-Resolved Light Scattering Study on the Crystal Growth of MOF-5 in Solution}}}, doi = {{10.1021/ja068835i}}, volume = {{129}}, year = {{2007}}, } @article{42003, author = {{Meister, Annette and Bastrop, Martin and Koschoreck, Sven and Garamus, Vasil M. and Sinemus, Thomas and Hempel, Günter and Drescher, Simon and Dobner, Bodo and Richtering, Walter and Huber, Klaus and Blume, Alfred}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{14}}, pages = {{7715--7723}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Structure−Property Relationship in Stimulus-Responsive Bolaamphiphile Hydrogels}}}, doi = {{10.1021/la7003479}}, volume = {{23}}, year = {{2007}}, } @article{42007, author = {{Huber, Klaus and Witte, Thomas and Hollmann, Jutta and Keuker-Baumann, Susanne}}, issn = {{0002-7863}}, journal = {{Journal of the American Chemical Society}}, keywords = {{Colloid and Surface Chemistry, Biochemistry, General Chemistry, Catalysis}}, number = {{5}}, pages = {{1089--1094}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Controlled Formation of Ag Nanoparticles by Means of Long-Chain Sodium Polyacrylates in Dilute Solution}}}, doi = {{10.1021/ja063368q}}, volume = {{129}}, year = {{2007}}, } @article{42005, author = {{WITTE, T and HALLER, L and LUTTMANN, E and KRUGER, J and FELS, G and Huber, Klaus}}, issn = {{1047-8477}}, journal = {{Journal of Structural Biology}}, keywords = {{Structural Biology}}, number = {{1}}, pages = {{71--81}}, publisher = {{Elsevier BV}}, title = {{{Time resolved structure analysis of growing β-amyloid fibers}}}, doi = {{10.1016/j.jsb.2007.02.006}}, volume = {{159}}, year = {{2007}}, } @article{25987, abstract = {{Mesoporous CeO2 was synthesised by using CMK-3 carbon as a structure matrix.
