| Abstract: | We describe a system that supports practical, vision-based user interfaces, addressing the issues of a usable interaction paradigm, support for application developers, and support for application deployment in real-world environments. Interfaces are defined as configurations of predefined interactive widgets that can be moved from one surface to another. Complex interfaces can be dynamically reconfigured, changing both form and location on the fly, because the functional definition of the interface is decoupled from the specification of its location in the environment. We illustrate the power of such an architecture in the context of projected interactive displays.Published online: 13 July 2004 |
