Today, virtual world applications typically use CAVE-like multi screen projections. While those provide a high degree of immersion, the come along with a couple of disadvantages for their users:

• Usually only the correct position and orientation of a single user are tracked. Thus all other users will observe disturbing artifacts – in particular at the edges of the canvases
• The required space to set-up the projections is enormous – at least a very large room or even a three story building is required
• The VR environments are not with the users, but usually located at a central location
• Users have to wear various kinds of individual equipment (tracking sensors or markers, glasses, input devices and even Filzpantoffeln) – preventing a spontaneous usage.

The goal of our research is to overcome these barriers and allow for a seamless integration of immersive 3D environments with the individual working environment of the users.

Thus, we research the usage of autostereoscopic displays as well as position- and orientation-based but deviceless interaction.
