Active Environments: Sensing and Responding to Groups of People

Abstract:

Most environments are passive– deaf, dumb and blind, unaware of their inhabitants and unable to assist them in a meaningful way. However, with the advent of ubiquitous computing – ever smaller, cheaper and faster computational devices embedded in a growing variety of “smart” objects – it is becoming increasingly possible to create active environments: physical spaces that can sense and respond appropriately to the people and activities taking place within them. Most of the early ubiquitous computing applications focus on how individuals interact with their environments as they work on foreground tasks. In contrast, this paper focuses on how groups of people affect and are affected by background aspects of their environments.
