This course takes both a practical and theoretical approach to introduce the principles, methods and tools for including “non-standards” properties inside interactive systems and interaction technologies. The course focusses on safety, dependability and security but encompasses additional contributing factors such as privacy, availability and trustworthiness and relate them to HCI-centric properties such as User Experience and Usability. The course will cover design, implementation and evaluation activities to assess these properties. A special attention will be made on how the properties are competing with one another in terms of knowledge of designers and resources required at development time. To paraphrase Susan Dray: “if it is not usable, it does not work” this course will argue that “if it does not work (i.e. it is not dependable) it is not usable” as well as “if it is not safe, it is not usable”. The concepts in this course will be supported by multiple concrete examples taken from industries including autonomous cars, aircraft cockpits, large command and control systems but also research labs prototypes targeting at deploying technologies in real-life settings.
