Part of self-service check-in systems in China are designed without taking user-centered design methods and guidelines into account. According to our research conducted at two airports in China, many users are not satisfied, some users even frustrated and give up using self-service check-in system. This significantly increases staff's working load and leads to great waste of resources. Therefore, redesigning the current problematic self-service check-in system based on user-centered methods becomes crucial in order to improve the usability of self-service check-in system in China, and to enhance user experience. In this paper, distributed cognition theory is applied for studying how the information process between human and artifacts in a system. The paper provides a review of previous research based on different user-centered methods and adds a new concept into the extended resources model stemmed from distributed cognition for guiding the redesign process of the current self-service check-in system.

The focus of most information fusion research, so far, has been on the technology, The information processing in machines. However, the importance of also understanding human information processing, and the interaction between humans and machines, is gaining increasing recognition. This position paper argues that a distributed cognition perspective, which considers cognitive processes not as taking place solely inside people's heads, but as distributed over human thought processes and the material, social and organisational environment they are embedded in, may help to provide a deeper understanding of information fusion processes.

In this paper, we analyse interactions between secondary students and pre-service teachers in an online environment in order to understand how their meaning-making processes embody distributed cognition. We begin by providing a theoretical review of the ways in which literacy learning is distributed across learners, objects, tools, symbols, technologies and the environment in modern English language arts classrooms. This is followed by a case study where we identify how programme values, textual resources and cultural schema function as distributed tools. In traditional schools, with an emphasis on taking standardised tests, the learning environment is designed on the view that learning is a transaction that happens solely 'inside the head'. Unfortunately, this pushes many students to the margins of classroom engagement and participation. By analysing students' and pre-service teachers' online discourse, we argue that virtual spaces can facilitate critical dialogue and can act as catalysts for a distributed theory of mind.

distributed cognition, as it considers how technologies augment cognition, informs technology integration in education. Most educational technologists interested in distributed cognition embrace a representational theory of mind. As this theory assumes cognition occurs in the brain and depends on the internal representation of external information, it is informed by a mind/body dualism that separates the individual student from material things. Alternatively, the theory of the extended mind describes the mind as a dynamic system of interactions inclusive of human agents, technologies and other material things. Refusing the mind/body dualism, if one element is removed, the quality of cognitive activity declines. Across the cognitive sciences, there are debates between these representational and extended theories that have implications for what it means to be a student and for technology integration. However, distributed cognition research in educational technology ignores these debates. Instead, this research is conditioned by the discursive practices of a neoliberal assemblage of political, commercial and pedagogical institutions. In this era of high stakes testing, as the individual student is measured, evaluated and otherwise made subject through these practices, this assemblage expresses a tacit commitment to, and is productive of, the subjectivity of the individual student and thus benefits from the representational theory of mind. In this way, regardless of the recognized legitimacy of the theory of the extended mind, sustained by neoliberalism the field of educational technology will not soon question the veracity of the representational theory of mind or the mind/body dualism upon which it depends.

Studies of patient safety have identified gaps in current work including the need for research about communication and information sharing among health care providers. They have also encouraged the use of decision support tools to improve human performance. distributed cognition is the shared awareness of goals, plans, and details that no single individual grasps. Cognitive artifacts are objects such as schedules, display boards, lists, and worksheets that form part of a distributed cognition. Cognitive artifacts including the Availabilities Sheet, Master Schedule, Operating Room (OR) Graph and OR Board provide a "way in " to understand how acute care teams plan and manage the balance between care demands and staff resources. This work has import for the way that medical informatics supports the organization, management, and use of health care information through software and computing systems. Better digital cognitive artifacts will benefit team work processes, planning, communications, resource management and, by extension, patient safety.

Knowledge-based communities bring together persons who collaborate and interact in order to produce knowledge. The tasks involved in this production are usually described in terms of "epistemic communities": groups of individuals working on shared topics in pursuit of a common goal of knowledge production. Focus is thus placed on the formation, evolution and interactions of these communities - in general, on processes of collaboration. The objective is twofold: on one hand, describe how epistemic communities emerge and overlap at various hierarchical levels and, on the other, expose the determinants of collaboration between members of these communities. In an attempt to formalize the analysis of distributed cognition, an epistemic community is defined as the largest set of agents sharing and, working on, the same set of concepts. This formal definition helps us describe the distributed structure of knowledge production;understand the impact of this structure on the perception and arrangement of activities related to distributed cognition and appraise dynamically the stability over time of the distribution of tasks within the network, in spite of a continuous turnover among members. An empirical study of a community of embryologists illustrates this approach. (C) 2008 Elsevier Masson SAS. Tous droits reserves.

Virtual environments are able to extend the space ofinteraction beyond the classroom. In order to analyze how distributed cognition functions in such an extended space, we suggest focusing on the architecture of intersubjectivity. The Euroland project-a virtual land created and populated by seven classrooms supported by a team of researchers-was analyzed with the aim of tracking down the process and the structure ofintersubjectivity. Participants were located in different cities in two countries-Italy and the Netherlands. At the end of the project, the initial empty virtual world was filled with virtual artifacts borne from the intersubjective process. A group often 13-year-old students was observed throughout the project. Seven videotapes were collected in the classroom. By analyzing the videotapes, a set of episodes revealing intersubjectivity was captured and discussed. Intersubjectivity first concerned only participants and tools located in the classroom. Later, partners at a distance and the various communication tools available entered the architecture of intersubjectivity. Finally, intersubjectivity revealed not only information, but the reciprocal perception of the roles and awareness of a joint project. From the episode analysis, recommendations for teachers' use of virtual technology were drawn.

Inexpensive displays make large, tiled displays attractive for visual analysis and collaborative investigation. Especially in multi-user environments, the increased space allows to better organize the findings and results and, therefore, helps to improve collaboration. One important requirement is that all users can navigate seamlessly on the whole display space, while employing the standard software they are familiar with. In this paper, we present a seamless desktop infrastructure for distributed cognition and collaboration. Our infrastructure only uses standard hardware and software. By choosing a minimally invasive, web-centric approach, we can integrate existing web applications and visual analysis software with little or no effort into our system. We can even leverage existing synchronization mechanisms built into many web applications today.

An artifact ecology is an environment where multiple heterogeneous technologies co-exist and are interlinked as a unified system. To construct effective ecologies of artifacts for collaborative activities we need to acquire deep understanding of the complex interactions and interdependencies between users and tools. Researchers have identified distributed cognition (DC) as a powerful tool for understanding these interdependencies. In this study, DC, and particularly the DiCoT framework, were considered ideal for constructing this understanding for four student-groups during collaborative activities in an artifact ecology. Using DiCoT we analysed learners' behaviour and how the artifact ecology supported collaboration and cooperation. The cognitive system was described from three different perspectives - physical layout, information flow and artifacts -which (i) allowed an in-depth understanding of the interactions among learners and tools during collaborative activities and (ii) provided insights on how the affordances of the artifact ecology supported collaboration and coordination.

Our research aims to identify children's communicative strategies when faced with the task of solving a geometric puzzle in CSCL contexts. We investigated how to identify and trace distributed cognition in problem-solving interactions based on discursive cohesion to objects, participants, and prior discursive content, and geometric and cooperative concepts. We report on the development of a method of coding and representation of verbal and gestural content for multimodal interactional data and initial application of this framework to a microethnographic case study of two small groups of 7 and 8-year-old learners solving tangram manipulatives in physical and virtual desktop settings. We characterize the establishment of shared reference points as "coreferences" which cohere on object, para, and meta-levels through both gesture and speech. Our analysis foregrounds how participants establish common referential ground to facilitate collaborative problem solving with either computer-supported or physical puzzles. Using multimodal analysis and a theoretical framework we developed to study interactional dynamics, we identified patterns of focus, dominance, and coalition formation as they relate to coreferentiality on multiple levels. Initial findings indicate increased communication and cohesion to higher-level principles in the virtual tangram puzzle-solving setting. This work contributes to available models of multimodal analysis of distributed cognition using current manipulative technologies for early childhood mathematics education.
