Abstract

When designing applications and interfaces within the area of safety critical environments the user plays an important role. During the design phase of such applications and their interfaces, companies argue that they regard the user and comply with their needs when defining user interfaces for safety critical systems. Nevertheless the usual process that is went through in this domain is that users are rarely consulted during the requirements engineering and design process. Usability requirements are often defined by the customer himself without consulting the user and defining the user's and usage requirements. When regarding the whole spectrum of safety critical applications that are used in safety critical environments it is not possible to simply define safety critical parameters and requirements that are taken in general into account when defining such user interfaces. In order to accomplish with this we use the approach of using and reusing patterns that serve as already proven examples for design problems to address the issue of regarding the user within a user interface design process. Having the threat for people's life in focus the appropriate design solutions are evaluated against this problem and requirement. Through building a pattern repository that reflects the design issues for user interfaces within such areas we address the manifold issues of safety critical environments and propose a solution-oriented approach of addressing the user and his requirements within safety critical environments.
