Whether or not a computerized system enhances the conditions of work in the application domain, very much demands on the user interface. Graphical user interfaces seem to attract the interest of the users but mostly ignore some basic rules of visual information processing thus leading to systems which are difficult to use, lowering productivity and increasing working stress (cognitive and work load). In this work we present some fundamental ergonomic considerations and their application to the medical image processing and archiving domain. We introduce the extensions to an existing concept needed to control and guide the development of GUIs with respect to domain specific ergonomics. The suggested concept, called model-view-controller Constraints (MVCC), can be used to programmatically implement ergonomic constraints, and thus has some advantages over written style guides. We conclude with the presentation of existing norms and methods to evaluate user interfaces.

User interfaces in interactive simulations convey the dynamic behavior of the modeled system and allow the analyst to interact with the executing simulation. Traditionally, the software to display system behavior and to facilitate user interaction has been embedded in the simulation model. Such tight integrations make it difficult to maintain large simulations and impose unnecessary limitations on the development of interfaces to a simulation model. This article presents a portable, object-based architecture, called JADIS (Java-based Architecture for Developing Interactive Simulations), for developing interactive simulations. The architecture is implemented in Java and applies the model-view-controller paradigm to the development of interactive simulations. This article describes the JADIS architecture and presents its application to an aircraft repair time analysis problem in the domain of airbase logistics.
