<p>A Spatial Augmented Reality (SAR) system, methods and components are described. The SAR system comprises a SAR device, such as a computer, and a SAR platform such as a set of projectors and object tracking systems that are used for producing a SAR environment. In one embodiment the SAR device comprises a loader for receiving and executing one or more SAR application modules and a SAR engine for receiving the input data and for interfacing between the SAR application modules and the output (ie SAR platform). The architecture of the SAR engine provides a SAR environment independent interface between the one more SAR application modules and the projectors and object trackers. The SAR engine is responsible for providing perspectively correct projected images in the SAR environment and performing any necessary coordinate transformations, and providing updates to application modules, as well as automating many common tasks. This significantly simplifies module development and makes it easier to develop Spatial Augmented Reality (SAR) applications as developers no longer need to manage the projectors and tracking systems or be concerned with projection specifics (eg number of projectors, locations, resolutions, etc).</p> |
