....Sony Glastron) and Virtual Table (a workbench like device) are possible. For 3D rendering Studierstube is using SGI OpenInventor. To enable multiuser applications a system called distributed OpenInventor[9] is running on top of Inventor. Studierstube also tries to nd a high quality user interface[10]. It s using Personal Interaction Panel (PIP) PIP is a two handed interface to control Studierstube[9] It consists of a small panel (about 20x20 cm) and a pen which can be used as 3D mouse . Both of them are separately tracked. But the application can replace those tools with anything that is ....

....The Studierstube project at Vienna University of Technology is one of the research outfits that have been looking at software architectures more closely [24] However, the architecture can so far be seen only partially as a framework. Reusability is mainly for testing new user interface paradigms [23] and configuration of the tracking subsystem [19] In contrast, our approach modularizes entire AR systems as a set of services which connect dynamically at runtime. Columbia University s Computer Graphics and User Interface Lab has also been involved in assembling different types of AR ....

....communication as well as interaction with both virtual and real objects is possible. This approach fits well into a conventional office environment that is augmented with heterogeneous media, as exemplified in UNC s office of the future [26] and Columbia s EMMIE [8] projects. In previous work [31] on the Studierstube system (Figure 1) we have demonstrated how a collaborative augmented reality system can provide convergence of several aspects of user interfaces: Multiple users can be accommodated simultaneously; multiple applications can be used concurrently by multiple users or ....

....objects from a foundation class, so that they can inherit a standard interface that will allow the surrounding simulation framework to talk to them in a meaningful way. Some approaches take this idea to the extreme by only providing a kernel capable of loading extensions [40, 22] Studierstube [31] uses object oriented runtime extension through subclassing. New node classes for OIV are loaded and registered with the system on the fly. Using this mechanism, we can take the scene graph based approach that avoids a dual database (graphical application data) to its logical consequence by ....

....that is filled with both real and virtual objects. Moreover, threedimensional interaction opens up new application areas such as collaborative computer aided design. Different display platforms can be used to establish a collaborative AR, e.g. optical see through HMDs in our own Studierstube [21, 22] system, video see through HMDs in the Shared Space work [3] or hand held displays in Transvision [19] Other approaches constrain collaborative AR to special active surfaces [20] or used it in a heterogeneous environment, e.g. EMMIE [5] or metaDesk [26] Finally, collaborative AR can also ....

....instance, and even the location of an application in a distributed environment or for ubiquitous computing, can be expected to change over time. Clearly, a different set of networking mechanisms than traditionally researched in the context of large scale DVEs become important. In previous work [23], we have presented Studierstube, a work environment that mixes AR, ubiquitous computing and other user interface paradigms to support multiple users and applications in a heterogeneous environment. In this paper, we present two new tools that radically extend the flexibility of Studierstube s ....
