The workload of air traffic controllers on the coordination of air traffic is enormous. With increasing air traffic the mental workload will rise in future. Today an air traffic controller has a variety of HMI to interact with. This situation requires a high level of cognitive effort, which makes it difficult to focus on the primary activity of air traffic control.
Therefore, the DFS CONCEPT DESK was designed. This integrated prototype system of hardware and software includes numerous technical display and interaction systems in a homogeneous workplace concept. The final system consists of two displays (>85”), of which the horizontal display is equipped as a multi-touch display. The entire system is operated via touch input, physical artifacts (avatars) - and hardware keyboard for numerical input. The system integrates all content into a homogeneous visualization and interaction methodologies previously presented separate HMI. With the help of this system a lot of different workspaces and different interaction methodologies for the future interaction between air traffic controllers and the air traffic can be evaluated.

Due to different previous project it was known that the interaction of ATC does not work optimally with the existing technology. The decisions of ATC based on a complex information situation. In the Tower of an hub airport there are up to 11 different hmi systems, the external view and the acoustic information of his colleagues influencing the decision of the ATC. The aim of the project was to reduce the variety of information massively with the aim of reducing the cognitive workload of the ATC. The studies focused primarily on the number of technical information (and their heterogeneous data representation) to unify and interacting with these. Within the project, an experimental workspace should be constructed to:
− representing consistent interaction principles
− Interpret information for the ATC
− Allow intuitive interaction

The CONCEPT DESK was deliberately designed very simple. The focus was on keeping the work area as large as possible. Due to the use of rear projection for the horizontal surface of the table could be designed very delicate. In the vertical one flat screens is used. The GUI of the CONCEPT DESK was drafted only prototypically. The aim was to give users a basic impression of a future interaction. So only fundamental interaction principles were outlined and implemented - the design should not give the impression of a final product. The goal was to involve the user within the design of future HMI systems.
