Theoretical and technological progress has revived the interest in the design of services for the support of co-located human-human communication and collaboration, witnessing the start of several large-scale projects over the last few years. Most of these projects focus on meetings and/or lecture situations. However, user-centred design and evaluation(More)
An important aspect of redesign for usability is to evaluate the system with its real users in order to explore implications for better design.

In this paper, we present an approach(More)
Coalitions, which allow traders to form teams, can sometimes accomplish tasks more efficiently than individuals. The core has become a popular solution concept in economic applications for researchers in Computer Science, because it provides a way to find stable sets. However, its problems hinder researchers from applying it to a real world market. This(More)
