Using tabletop devices for controlling complex applications is rather uncommon as interaction on tabletops is still very error-prone. Especially in everyday life settings, there is a multitude of sources of distractions and input errors. The tabletop-based management of cyberphysical systems influencing both the virtual and the real world introduces new challenges with respect to reliability and fault tolerance of the user interface. In this paper, we present an interaction concept for complex management applications on tabletops introducing more resilient gestures for different stages of the interaction. The interaction concept provides more reliable interactions than the basic set of touch gestures does and proves suitable for more complex applications. A user study conducted as part of the work confirms the concept's increased accuracy without influencing the overall usability. As an example, we present a process management application for cyber-physical systems implementing the interaction concept.
