A Framework for Multi-User Support in Instrumented Public Spaces

The emerging trend towards complex technology that supports multiple users in public spaces is evidenced by the presence of shared displays in shopping malls, museums, and airports As sensing and interaction begin to play a greater role in these environments, application and interaction concepts are evolving to take the distribution and dynamics of users and devices into account. In this paper we describe a layered approach to support multiple in environments that allows concurrent interaction with multiple devices and displays. We further identify issues that arise in public, interactive spaces with multiple users and discuss how we address them in our proposed framework.
