Using image warping of a projection based on viewer perspective it is possible to extend a physical space with virtual projections that respond to your movement. Using view-dependent image-based and geometric warping, radiometric compensation, and multi-focal projection these guys have developed an interesting approach to merging the physical with the virtual.

Such an approach does not only offer new possibilities for augmented reality and virtual reality, but also allows merging both technologies. This potentially gives some application domains — like architecture — the possibility to benefit from the conceptual overlaps of AR and VR. From Future Feeder
