The architecture of the system VRECKO is designed for the rapid prototyping of techniques for human-computer interaction. The architecture is flexible, but simple. Virtual environment entities and other components can be configured at run time. We demonstrate the flexibility of the approach on several examples of experiments and tools which were realized in VRECKO.
