I recently came into possession of this paper I wrote along with some colleagues from CRP-GL a number of years ago. Although from 2006 it may still be of use to some others on here.
An Ambient Workplace for Raising Awareness of Internet-Based Cooperation
Benoît Otjacques, Rod McCall and Fernand Feltz
Abstract. This paper discusses a prototype desktop ambient display system
known as the Ambient Workplace (AW) that is used to visualise some aspects
of cooperation among a group of co-workers. The AW draws on the ambient
technology paradigm by providing a visualisation that represents the
interactions of the co-workers (either individuals or groups) in their peripheral
attention zone. The paper discusses the development of a prototype system
based on a series of indices and uses a maritime flags metaphor. The paper also
presents some early results from a user study.
