For the visualization of the process data, 3D graphics or 2D GUI elements can be used. For a single value, e.g. energy flow, 3D objects can visualize the behavior of the value [15]. For many various process values 2D elements are a better possibility to give an overview of the process to the user. The aim is to design the GUI as user-friendly and problemoriented as possible. The user should see the important information and errors immediately and should be capable to interact with the GUI to display the current important information. The GUI should always show the relevant data and adjust itself to the current process state.
