This paper describes an experimental comparison of three variants of a meeting browser. This browser incorporates innovative, multimodal technologies to enable storage and smart retrieval of captured meeting. Over a hundred subjects had to work in a design team in which they had to prepare and carry out a final meeting, while supported by one of the browser variants. In one condition, teams worked without such support. Measures on individual characteristics, the team, the process and outcome of the project, and the usability of the browsers were taken. The results indicate that a multimodal meeting browser can indeed improve meetings. Further analysis of the now available data will provide additional insight into how browsers can contribute to more efficient and satisfactory meetings, improved team performance and higher quality project outcomes.

To build the effective information systems Scandinavian tradition emphasizes and encourages the participatory design methods which involves both designers and users equally in building the systems. While the main intention of Scandinavian tradition is to refocus the dominant orientation of systems developers by involving users but one really wonders whether it can be applied in the context of developing countries particularly in a country like India where the structures are rigid, hierarchical and strongly bureaucratic in nature. In spite of the fact that health sector being a key social area in India’s developmental administration it is highly fragmented and receives low priority. In India, while the general administration is mostly concentrated at the district level, health and family welfare administration has been centralized at state and central levels. This coupled with the excessive concentration of powers in the secretariat system of governance, has considerably centralized planning and monitoring. Keeping in view the above complexities and challenging conditions this paper tries to understand using case study as a method how participation at different levels affects the design and implementation of Health Information Systems in primary health care sector in India.

The importance of social relation has never been as vital as of now, in an age of sound bites, aging population and busy work schedule, contemplating social behavior has become a rarity. The ’Structuration’ theory [2] elaborates the fact that how much social relation’s are important in human life. Here we re-define basic concept and category (types) of mobile community. A realization of mobile communities through unified UI for mobile devices is believed to provide users efficient communication ways while satisfying properties of various communities. Such unified UI led to drive an adaptive and intuitive user interfaces that depict real-time interaction involving multiple parties, contents and activities. Many different scenarios emerge with the proposed UI to give a deeper thought and understanding about the role of mobile community in everyday life and help promoting user’s communication experience.

As extensive amount information is required within a R&D environment, an automated information system could save a considerable amount of time and efforts. There are currently many researches to overcome the information overload phenomenon, including information systems, recommender systems and adaptive hypermedia, and this paper presents an adaptive information providing system utilising some characteristics of these technologies to support R&D and collaborative meeting environments. The system described in this paper aims to present the potential synergy between recommender systems and adaptive hypermedia systems.

Organizations use several methods to communicate formal and informal information. Currently, message boards or corkboards are used as a means for sharing information, coordinating activities and communicating with others. Using our organization as a case study, we observed that there are many message boards around the physical environment and most of them are covered with documents announcing upcoming meetings, seminars, conferences and other events. Besides that, some of the documents were out-of-date which makes it more difficult for users to find information that is relevant for their activities. To support the dissemination of information in organizations, we are proposing a Time-aware Public Display System that enables organization personnel to become aware of relevant information in a timely fashion. We used the Perspective Wall visualization to enable the categorization of the information into topics and dates. We evaluated the system design which shows that users considered appropriate and useful the presentation of information on the Time-aware Public Display.

The paper outlines a theoretical framework for the conceptualisation and design of collaborative systems for design organisations. The intent is to examine and support the idea of ’co-purposing’ as an influential design metaphor for the analysis of design teams and the development of design support collaborative systems in contexts where systems’ designers collaborate with their clients. By offering associations to the work activities and the social interaction of designers in actual design workspaces, we propose that the metaphor of ’co-purposing’ can stand as an alternative perspective in the analysis and design of potentially new realisations of computer supported cooperative work systems for supporting teamwork.

Our research focuses on as a key to implementing an ambient atmosphere of people, that is, the feeling of another’s proximity or presence. Such knowledge is sought for constructing an ultra-realistic communication system with shared reality. This study examines whether people’s impressions and behaviors are affected by (a) the existence or (b) non-existence of ambient sounds. A pilot study is conducted by using the ambient sounds of a newspaper’s pages being turned and a glass being placed on a table in an adjacent room. No difference in the subjects’ surface behavior between the two ambient-sound conditions is observed explicitly. However, the preliminary results suggest that participants feel an ambient atmosphere of people in the next room when the ambient sounds are output. They also suggest that the participants become nervous as they feel the presence of other people. This study demonstrates the importance of investigating the fundamentals of an ambient atmosphere in interaction via an ultra-realistic communication system.

This paper extends the knowledge and understanding of art-technology collaboration. It reports upon a close empirical study of how computer programmers interacted with a digital artist to develop a computer-based interactive artwork. Analysis of the data collected showed that the joint uncovering and resolving of assumptions made by each party led to increased shared understanding. The contribution of this paper is to provide a better understanding of creative collaboration, particularly focusing on how developing the artefact increased the understanding between the artist and technologists.

This paper presents an approach to investigating interdisciplinary collaboration between an artist and a technologist based on case study methods. The aim of the research is to understand how artists and technologists communicate with each other during a collaborative process. The paper begins with a brief account of the art-technology context, and goes on to describe how the data was collected and how the analysis framework was developed specifically for this context. At the end of this paper, we discuss the preliminary findings which illustrate the characteristics of participants’ communication behaviours in art-technology collaboration.

The high penetration of mobile devices implies that we are closing up to the vision of ubiquitous media environments. This paper reports from a broad survey about barriers, use patterns, and motivations for using mobile media services. The aim is to contribute to the understanding of mobile service adoption process by studying users in different phases of the adoption process. The findings imply that mobile services are still not adopted and ubiquitously ingrained in use patterns. There is still a long way to go.
