- In designing socially interactive robots we have focused on robot movement and its role in multi-modal human-robot communication. In this chapter we describe design and evaluation of robot body movements supporting communication, investigating the idea of using speed and orientation adjustments as design elements in human-robot interaction. The scenario studied includes a robotic shopping trolley that offers products via speech and GUI to the user while both are moving in a supermarket-like environment. Our results show that if the robot slows down while making such offers, users are more prone to react upon them and to take the product. However, even from our early pre-study with mock-up robots we observed that users tended not to mention the robot’s slow-down movements, even if these movements were shown several times to them during a video-based debriefing. This phenomenon, that users react implicitly on the robot’s movements without being consciously aware of them, was confirmed during an experimental study with a fully integrated robot prototype. We discuss our results by reflecting on human-robot interaction design methods, and we draw implications from the lessons learned in the study of the design of robot behaviours. In particular, we list a whole set of challenges for HRI when both the user and the robot are moving.

- The importance of groupware tools in e-learning practice is increasing, because of their educational relevance and of the importance of group abilities in today's job activities. The paper addresses some critical issues of asynchronous collaborative tools hosted in Web-learning platforms. A model to capture user quality perceptions for these tools is presented, and an investigation conducted in three case studies where e-learning platforms were used to share and comment on written works is reported in detail. Quantitative and qualitative data are used in a complementary way to capture the complexity of educational collaborative activities. The impact of technologies on work organization, writing and peer-feedback activities is discussed. Users dedicated more time to feedback activities than they would have in real-life contexts, and paid more attention to the style and content of their writing. Communication was more focused and honest than in real life (even though more distant and at the risk of misunderstanding), and its indirectness encouraged shy and impaired people. Usability problems emerged from platform design, educators' choices and server-side settings; Web-based systems seem to pose specific usability issues when users are required a strong active role; compatibility issues highlight the need for a closer Web standard compliance.

- This paper describes how the Wizard-of-Oz framework can be applied to a service robotics scenario. A scenario the Home Tour Scenario - involving a collaborative service discovery and configuration multimodal dialogue for the robot is described. The role of the wizard operators producing dialogue and robot movements is discussed as well as the specific simulation tools used: the Dialogue Production Tool and the Joystick Navigation Tool. Some attention will be paid to the pilot studies performed as a preparation for the unified Home Tour Scenario.

Developing a Contextualized Multimodal Corpus for Human-Robot Interaction

Konferensbidrag (refereegranskat)abstract
- This paper describes the development process of a contextualized corpus for research on Human-Robot Communication. The data have been collected in two Wizard-of-Oz user studies performedwith 22 and 5 users respectively in a scenario that is called the HomeTour. In this scenario the users show the environment (a single room, or a whole floor) to the robot using a combination of speech and gestures. The corpus has been transcribed and annotated with respect to gestures and conversational acts, thus forming a core annotation. We have also annotated or linked other types of data, e.g., laser range finder readings, positioning analysis, questionnaire data and task descriptions that form the annotated context of the scenario. By providing a rich set of different annotated data, thecorpus is thus an important resource both for research on natural language speech interfaces for robots and for research on human-robot communication in general.

- This paper describes the experiences from the iterative design of a fetch-and-carry-robot, to be used by motion-impaired people in an office environment. A user-centered approach was chosen, involving several steps of information elicitation to inform the design. We describe the main elements of the design process, the communication and interaction components of the final prototype system, and an evaluation of the system in the form of a longitudinal study. Results from this study confirmed that continuous testing with users is extremely important in the design process for service robots. The trials have also revealed that interaction design for robots should not focus only on the individual user, but that other members in the environment can be seen "secondary users" or "bystanders" who tend to relate to the robot actively in various ways. We conclude that these social and collaborative issues should be studied in future research.

- This article presents the results from a video-based evaluation study of a social robotic telepresence solution for elderly. The evaluated system is a mobile teleoperated robot called Giraff that allows caregivers to virtually enter a home and conduct a natural visit just as if they were physically there. The evaluation focuses on the perspectives from primary healthcare organizations and collects the feedback from different categories of health professionals. The evaluation included 150 participants and yielded unexpected results with respect to the acceptance of the Giraff system. In particular, greater exposure to technology did not necessarily increase acceptance and large variances occurred between the categories of health professionals. In addition to outlining the results, this study provides a number of indications with respect to increasing acceptance for technology for elderly.

- Human-Robot Interaction (HRI) research is here presented into social robots that have to be able to interact with inexperienced users. In the design of these robots many research findings of human-human interaction and human-computer interaction are adopted but the direct applicability of these theories is limited because a robot is different from both humans and computers. Therefore, new methods have to be developed in HRI in order to build robots that are suitable for inexperienced users. In this paper we present a video study we conducted employing our robot BIRON (BIelefeld RObot companioN) which is designed for use in domestic environments. Subjects watched the system during the interaction with a human and rated two different robot behaviours (extrovert and introvert). The behaviours differed regarding verbal output and person following of the robot. Aiming to improve human-robot interaction, participants' ratings of the behaviours were evaluated and compared.
