The Extended Virtual Table: An Optical Extension for Table-Like Projection Systems

  title={The Extended Virtual Table: An Optical Extension for Table-Like Projection Systems},
  author={O. Bimber and L. Encarnaç{\~a}o and Pedro Branco},
  journal={Presence: Teleoperators \& Virtual Environments},
A prototype of an optical extension for table-like rear-projection systems is described. A large, half-silvered mirror beam splitter is used as the optical combiner to unify a virtual and a real workbench. The virtual workbench has been enabled to display computer graphics beyond its projection boundaries and to combine virtual environments with the adjacent real world. A variety of techniques are described and referred to that allow indirect interaction with virtual objects through the mirror… Expand
