....(avatar representation, text, audio or even video channel) high network performance and intelligent distribution strategies have to support these tasks. Local multi user systems like CAVE [Cruz Neira, 1993] Responsive Workbench [Krger, 1995] Shared Space [Billinghurst, 1996] and Studierstube [Fuhrmann, 1997] focused on topics in scientific visualization and collaborative work. Social communication is provided by these systems naturally, participants are located in one room. We identified the ability to display different information to each participant as a requirement for visual privacy. The CAVE ....
....We show how to overcome limited precision in an augmented reality environment, and how individual views onto a common scenario are managed. 3 2. Salon de Jeux A multi user augmented gaming environment 2. 1 General Concept and Setup The setup we have chosen is similar to that of Studierstube [Fuhrmann, 1997], consisting of private see trough head mounted displays (Virtual I O i glasses ) and a Personal Interaction Panel (PIP) Szalavri, 1997] for each user. HMDs and interaction devices are tracked in position and orientation with a magnetic tracking system. The see through HMD does not block the view ....

....on the requirements of these registration accuracy and response time to physical actions, multi user collaboration systems with AR are categorized into four groups. First is the type where both requirements are not strict. This type includes applications such as collaborative information browsing [5, 7]. Secondly, there is a type that requires the accurate positional registration though it does not need high speed response. Collaborative design of mechanical parts and collaborative drawing are the examples of this kind. On the contrary, there is a type that requires the realtime response and ....

....while providing excellent data are in most cases prohibitively expensive and suffer in many cases from line of sight problems similar to the ones cited above. This holds especially in a collaborative situation where users standing close together examine and object between them, as for example in [FU97]. Tracking systems providing only positional data At the moment most virtual environments immersive and augmented use tracking systems providing only position and orientation. This includes commercial magnetic and mechanical tracking devices and advanced beacon based optical tracking systems ....
....the fear of bumping into obstacles. Objects in Studierstube may appear unlike in projection based display systems both between and beside users. Interaction and collaboration within arm reach of the users is possible and supported by scientific visualization applications we have presented in [FU97] and [FU98] Since the resulting scenarios lead often to situations where users heads, hands or bodies or the PIP had to occlude virtual objects, we had to find a method for efficient handling of these occlusions. The properties of Studierstube and our chosen hardware and software setup presented ....

The following sections describe implementation details of the our techniques and their integration in our virtual environment. 8. 1 Interaction in the Virtual Environment STUDIERSTUBE [17] is a multi user augmented environment which we use for scientific visualization [6]. It implements basic interaction methods like positioning objects by dragging them with a 6 DOF pen (figures 9 and 11) as well as conventional 2D interacFigure 12: Interaction using the PIP Figure 13: Contraction artifacts due to torsion tion elements like sliders, dials and buttons for ....
