In essence, we are searching for a 3D user interface metaphor as powerful as the desktop metaphor for 2D. At the heart of the Studierstube system, collaborative augmented reality is used to embed computer-generated images into the real work environment. In the first part of this paper, we review the user interface of the initial Studierstube system, in particular the implementation of collaborative augmented reality, and the Personal Interaction Panel, a two-handed interface for interaction with the system. In the second part, an extended Studierstube system based on a heterogeneous distributed architecture is presented. This system allows the user to combine multiple approaches--augmented reality, projection displays, ubiquitous computing--to the interface as needed. The environment is controlled by the Personal Interaction Panel, a two-handed pen-and-pad interface, which has versatile uses for interacting with the virtual environment. Studierstube also borrows elements from the desktop, such as multi-tasking and multi-windowing.

Methods to calibrate the projection parameters of the virtual cameras to that of the HMD have been presented in previous work.

We present a simple and fast calibration scheme, which does not require additional instrumentation or complicated procedures. This allows us to calibrate HMDs for specific users. The calibration process is presented to the user as interactively guided initialization step, which enables even inexperienced users to adapt the calibration to their eye distance and head geometry. The calibration is stable - meaning that slight errors made by the user do not result in gross miscalibrations - and applicable for see-through and video-based HMDs.
