In this paper we present a new approach for cooperation between mobile smart objects and projector-camera systems to enable augmentation of the surface of objects with interactive projected displays. We investigate how a smart object's capability for self description and sensing can be used in cooperation with the vision capability of projector-camera systems to help locate, track and display information onto object surfaces in an unconstrained environment. Finally, we develop a framework that can be applied to distributed projector-camera systems, cope with varying levels of description knowledge and different sensors embedded in an object.

The development of Smart-Its for building smart environments is discussed. Smart-Its are small, self-contained, stick-on computers that attach to everyday objects. These augmented objects become soft media, enabling dynamic digital relationships with users and each other. A Smart-Its consists of a core board with a wireless transceiver to let the device communicate with other Smart-Its, plus a sensor board that gives the Smart-Its data about its sorroundings. The major advantage of the system is that it allows designers and researchers to construct responsive or intelligent environments.@en
