Relying on a novel technique of per-pixel light control, we offer a complete, intuitive framework for realizing adaptive instant displays with the help of scalable projections. Simple bricks containing cameras and projectors are combined in a flexible, way to achieve increasingly immersive, interactive environments.

Our display metaphor has already proven to be effective in a wide range of application scenarios. With support for content replication, multiple views, dynamic collision-aware display reconfiguration and multi-user remote interaction, our displays lend themselves very well for collaborative engineering, design and modeling. Additionally, the simple inclusion of any personal laptop as a display source makes our system suitable for brainstorming meetings or presentations. Furthermore, due to the integrated focus and context techniques the use for visualization of large-scale datasets for intelligence analysis or edutainment is straightforward. Last but not least, everyday single-user office workspaces, which often are cluttered as we all know from experience, greatly benefit from the enhanced display and illumination flexibility. In all use cases mentioned above, the optional environment-aware adaptivity and shadow avoidance can continuously guarantee optimal visibility of projected displays at any time.
