for applications\nrequiring manipulation of complex three-dimensional information as a daily routine.\nIn essence, we are searching for a 3D user interface metaphor as powerful as the\ndesktop metaphor for 2D. At the heart of the Studierstube system, collaborative\naugmented reality is used to embed computer-generated images into the real work\nenvironment. In the first part of this paper, we review the user interface of\nthe initial Studierstube system, in particular the implementation of collaborative\naugmented reality, and the Personal Interaction Panel, a two-handed interface for\ninteraction with the system. In the second part, an extended Studierstube system\nbased on a heterogeneous distributed architecture is presented. This system allows\nthe user to combine multiple approaches--augmented reality, projection displays,\nubiquitous computing--to the interface as needed. The environment is controlled\nby the Personal Interaction Panel, a two-handed pen-and-pad interface, which has\nversatile uses for interacting with the virtual environment.
