- 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.

- 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.

- This paper presents a study aimed at exploring the effects of different modality combinations on collaborative task performance and employed joint task-solving strategies in a shared interface. The modality combinations visual/haptic, visual/audio and visual/haptic/audio were compared in an experiment in which users solved a task together, working in pairs in adjacent rooms. The application used contained a flat surface in a 3D interface on which piles of cubes were randomly placed in a grid. The task involved scanning for empty cells and placing continuously falling cubes until all empty cells were filled. The cubes and the flat surface were designed in such a way that they could be felt and heard and thus could be recognized by different kinds of haptic and audio feedback cues. This made it possible to scan the environment and read both absolute and relative positions in the grid. A quantitative analysis of task performance and a qualitative analysis of video recordings and interview data were performed. Results showed that task completion times were significantly faster in the visual/haptic/audio condition compared with the other conditions and that there were also significantly fewer errors, result checks of one's own actions and double checks of the partner's actions in the visual/haptic/audio condition than in the other conditions. Qualitative results show that participants work simultaneously to a larger extent in the visual/haptic/audio condition and that less communication occurred in the visual/haptic/audio condition compared with the other conditions. We argue that more modalities improved the awareness of the environment resulting in the participants feeling more confident with their interaction in the environment in the visual/haptic/audio condition. This resulted in improved task performance. The visual/audio feedback was better suited for solving the task than the visual/haptic feedback even though haptic feedback gave a significant added value in the visual/haptic/audio condition.

To quote or not to quote : Setting the context for computer-mediated dialogues

Tidskriftsartikel (refereegranskat)abstract
- Quoting (or contextual quotation) is a common element of interactive email discourse. By including a message or parts of it into the reply, the sender provides a discourse context for the message. However, there are also problems associated with this conversational strategy: It makes the message longer, more redundant, and sometimes even difficult to read. Moreover, verbatim repetition of an interlocutor’s utterance may be perceived as a violation of everyday norms of conversation. This article provides a pragmatic analysis of quoting as a conversational strategy. By means of descriptive analysis of data collected from two CMC settings, private email and Usenet newsgroups, the variability of quoting and its functions in dialogue are highlighted. In the concluding discussion, it is argued that technical properties of the email system and factors in the social context jointly affect the quoting strategies of CMC participants.
