Scape: supporting stereoscopic collaboration in augmented and projective environments

Our collaborative augmented reality system for multiple users simultaneously creates outside-in workbench views and inside-out life-size walkthrough views, bridging the virtual and augmented reality paradigms. Here we introduce a collaborative infrastructure - stereoscopic collaboration in augmented and projective environments(Scape). Scape seamlessly merges the paradigm of virtual reality with that of augmented reality in a single system and provides multimodality interface devices and unique widget interfaces to facilitate collaborative work in 3D environments. A custom-designed cross-platform application-programming interface (API) allows high and medium-level controls over the Scape workspace to enable augmented interaction and collaboration.
