However, this fact sometimes confuses us because most of messages in 2 channel seem to be meaningless, often said as graffiti. To understand the mystery of 2 channel, we assume the existence of something at the back of 2 channel that governs the activity of participants. Looking at 2 channel from this point of view, there could be many factors that affect online communication. For example, terms that seem to be meaningless for us might have some meanings for participants in 2 channel, and communication with the terms might activate interaction. In this paper, we aim at analyzing the dynamism of 2 channel by applying Structural Equation Modeling (SEM) to eight observable characteristics of communication including basic properties (message size, posting activity, reply rate, etc), anonymity, and specific expressions (jargons and ASCII arts peculiar to 2 channel). The structural equation model of 2 channel clearly shows various causalities among the characteristics, i.e. the use of specific expressions affects positively to chitchat-type communication, and negatively to discussion-type communication.

Built-in robot functionalities provide a degree of situational embodiment, self-explainability, and context-driven interaction. The concept of embodiment enables immersion of the teacher into distant 3D environments. In that way the level of mutual understanding between participants is increased compared to a 2D world. Moreover, the tools that accompany the interaction empower augmentation by revealing the additional information present in gestures, facial expressions, or gaze direction. We use three distinct sources fused in a multimodal approach (face emotion recognition, level of loudness, and body movement intensity). The change in one modality can change the overall system reasoning. The teacher can benefit from this information by adapting a presentation style and achieve a better rapport with students. The theoretical basis is provided by studies of human communication in psycholinguistics and social psychology. Usability evaluation is based on the Wizard of Oz approach, allowing a teacher to interact with students through an interface. The conducted experiments show encouraging responses. Future studies will show in what way and to what extent a cognitive robot can be truly effective in technology-enhanced learning.
Cooperation and Conflict in Knowledge-Intensive Computer Supported Cooperative Work

Any theoretical background to CSCW must be fundamentally interdisciplinary, drawing input from social psychology, organization theory, anthropology and linguistics, as well as from more computer-orientated disciplines, such as systems theory and design, knowledge engineering and so on. Consequently, it is clearly important to establish the boundaries for CSCW both as a coherent field of study and also as empirically observable human activity amenable to formal characterization. The present study is intended to illustrate what a CSCW-type analysis might look like under the constraint that it is more focused on the social nature of the human activity than, say, systems design; while at the same time being more strongly orientated towards the provision of a computationally-relevant framework than a social science description.

We explore ways of formalizing some critical aspects of these tasks and the possible benefits of such formalization for our understanding of both human and computer reasoning strategies. We present an inter-disciplinary analysis of expert reasoning with information in both stylized documents and multimedia, and discuss the differences between the kind of strategies we think people use and the kind that can be formalized and designed into an intelligent system.

This paper is devoted to the assessment of digital evidence which requires not only an understanding of the scientific technique that leads to improved quality of surveillance video recordings, but also of the legal principles behind it. Emphasis is given on the special treatment of image processing in terms of its handling and explanation that would be acceptable in a court of law. In this context, we propose a variational Bayesian approach to multiple-image super-resolution based on Super-Gaussian prior models that automatically enhances the quality of outdoor video recordings and estimates all the model parameters while preserving the authenticity, credibility and reliability of video data as digital evidence. The proposed methodology is validated both quantitatively and visually on synthetic videos generated from single images and real-life videos and applied to a real-life case of damages and stealing in a private property.

The design issues in this context focus on making such settings interactive enough to support natural communication and collaboration. The initial assumption is that users in an interactive v-c setting should be able to navigate the remote space in order to establish clear reference by pointing to people and objects in it. Clear reference to parts of the context in which conversations take place (that is, deictic reference) is an important factor in effective communication. With this aim, we enhanced the videoconferencing system with the ability to visualize abstract representations of pointers and investigated pointing gesture as a tool for collaborative referring. We thus designed a prototype that combines the communicative function of pointing gesture with a hybrid representation of real video and virtual objects (pointers) that identify particular parts of it. A game controller was employed for pointing and Augmented Reality (AR) for visualizing the referent in live video stream. Usability tests were run on two versions of the prototype using five common types of joint task. Evidence based on data from video recording, questionnaire, and interview, shows effectiveness of the system in mediating the communicative function of pointing. Test users adapted to the context of interpretation quickly. Feedback was provided for enhancing visualization and pointing technique. The method successfully captured relevant visuo-gestural and linguistic aspects of communication to inform design.

However, the implications of the workplace studies in construction, focused on the technology-mediated social and psychological phenomena, are profoundly theoretical. The main aim of this paper is to offer for discussion some key theoretical issues that sociological and cognitive theories of social intelligence may address and then inform the designers of ICT supporting real-life communication in the workplace. It is possible that the results of the discussion will influence the way we study language and interaction between agents, “either natural of artificial ….. that leads to creation of new knowledge and relationship among participants ” (cf. Workshop flyer) It is also possible that attempts to build a sound theoretical base for such a study will have far reaching co...
