Dealing with Conflicting User Interface Properties in User-Centered Development Processes

Whilst usability has been the most prominent user interface property in early Human-Computer Interaction (HCI) research other properties such as accessibility, inclusive design, user experience and, more recently security, trust and resilience (among many others) might also be important for the development of interactive system. It is interesting to notice that user interface properties might overlap and sometimes create conflicting recommendations. A good example is security which, by recommending users to deal with passwords reduces system usability by placing a burden on users. The ultimate goal of this workshop is to promote the investigation of multiple user interface properties in a user-centered design process. We are concerned by theories, methods and approaches for dealing with multiple user interface properties when developing interactive system. This workshop is organized by the IFIP WG 13.2 on Human-Centered Software Methodologies and the WG 13.5 on Resilience, Reliability, Safety and Human Error in System Development.
