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...
This paper provides an approach to evaluating collaboration tools for distributed teams. Selected tool characteristics that increase tool usefulness will be presented and this set of characteristics will be used as the evaluation framework. The value of each tool will be determined by the amount of characteristic presence. A number of tools will be evaluated with this framework.
The paper describes the design and implementation of a set of visual modeling editors. They aim to provide users with easy to use and customizable but yet semantically powerful tools for collaborative modeling in diverse domains of interest. The tools allow the creation, use and evolution of visual models and their underlying languages. The design, software architecture, technical implementation and...
Human interaction is one of the most important characteristics of group social dynamics in meetings. In this paper, we propose an approach for capture, recognition, and visualization of human interactions. Unlike physical interactions (e.g., turn-taking and addressing), the human interactions considered here are incorporated with semantics, i.e., user intention or attitude toward a topic. We adopt...
Much research has been devoted to collaborative tools for writing, group communication, reviewing, managing projects, and developing network infrastructures to support sharing activities. However the creation and display of foundational collaborative concepts that manage group work has not been paid significant attention. Information visualization potentially addresses the progression of distributed...
In this paper, we propose a framework which allows remote users to form conversation groups based on spatial relationship in a shared virtual space. Our proposed framework can transport awareness information of real world by capturing and transferring user's audio visual information. Our framework also provides functions useful to CSCW, which allow each user to simultaneously join different conversation...
A new field of research, visual analytics, has been introduced. This has been defined as "the science of analytical reasoning facilitated by interactive visual interfaces" (Thomas and Cook, 2005). Visual analytic environments, therefore, support analytical reasoning using visual representations and interactions, with data representations and transformation capabilities, to support production,...
