A modular system for collaborative desktop VR/AR with a shared workspace

We present a collaborative desktop virtual and augmented reality system with a shared physical workspace: the joint space station. It is constructed out of multiple, single-user near-field virtual or augmented reality stations using mirror-based displays. The joint space station provides high-resolution stereoscopic images and direct 3D interaction to all participants. The environment is modular, flexible, low-cost, and can be used under office working conditions. We describe the design, implementation, and application of a prototype joint space station, and discuss the merits and limitations of the concept.
