This thesis presents the concept of Cooperative Augmentation, a new approach to adding output capability to smart objects through cooperation with projector-camera systems.
Projector-camera systems provide a generic display service, available for spontaneous use by any smart object. We embed the knowledge required for visual detection, tracking and projection of non-invasive and interactive projected displays on object surfaces within the smart object itself and use embedded sensing to constrain the visual detection process.
Cooperative Augmentation allows smart objects to deliver visual feedback to users from implicit and explicit interaction with information represented or sensed by the physical object, supporting objects as both input and output medium simultaneously. This contributes to the central vision of Ubiquitous Computing by enabling users to address tasks in physical space with direct manipulation and have feedback on the objects themselves, where it belongs in the real world.
