Applying matrix-based methods for improving user experience of a driver advisory system

Users need tools to accomplish complex tasks in dynamic use situations; but meanwhile want the experience of product interaction to be intuitive and enjoyable. To achieve the goal of handling technologies and motives and mapping functions from the users' perspective, matrix-based method can be applied by designers. But those positive effects can only be achieved, if the method is viable and usable. In this work, a matrix-based method is applied in the case study of a rail driver advisory system (DAS) with a twofold purpose: (1) to adjust the method in order fit the specific and limited in term of resources frame of the project, and (2) to create new concepts for the complex interface of DAS in order to improve the drivers' experience and acceptance. The methodological proceeding with useful insights and best practices are presented in the paper. Furthermore, new dynamic DAS interface concepts are proposed as result of use case-based (i.e. functions most likely to be needed in a use case are clustered in one interface) approach.
