Projected augmentation II - a scalable architecture for multi projector based AR-systems based on ´Projected Applications´

Augmenting or annotating physical objects using steerable video projector and camera combinations works well in the range of the projection system. However, since these systems are usually mounted in fixed locations, users have to stay within a certain radius around that location. By using several of these AR-Projection systems, we can make the application roam these systems and thus follow the user beyond these limits. Using this method, we furthermore remove the need to hold the augmented objects in a suitable direction towards the projector and can reduce the possibility of shadowing the projection by the user. We describe an architecture based on our ´Projected Applications´ which coordinates the systems used to project the augmentations and keeps the projected applications´ states in sync between the projection systems.
