An Architecture and Framework for Steerable Interface Systems

Steerable Interfaces are emerging as a new paradigm used in realizing the vision of embodied interaction in ubiquitous computing environments. Such interfaces steer relevant input and output capabilities around space, to serve the user when and where they are needed. We present an architecture and a programming framework that enable the development of Steerable Interface applications. The distributed multi-layer architecture provides applications with abstractions to services of several novel components – for instance, steerable projection, steerable visual interaction detection, and geometric reasoning. The programming framework facilitates integration of the various services while hiding the complexity of sequencing and synchronizing the underlying components.
