Collaboration with Tangible Augmented Reality Interfaces

We describe a design approach, Tangible Augmented Reality, for developing interfaces for supporting face-to-face collaboration. By combining Augmented Reality techniques with Tangible User Interface elements, we can create interfaces in which users can interact with spatial data as easy as real objects. Tangible AR interfaces remove the separation between the real and virtual worlds and so enhance natural face-to-face communication. We describe several prototype applications showing how this design approach can be applied in practice.
