Value in experience: A design and evaluation framework based on case studies of novel mobile services

You cannot NOT have a user experience' (Lou Carbone) As McCarthy and Wright [1] put it, we do not just use technology; we live with it. Human-computer interaction (HCI) to an ever greater extent is occupying diverse domains of our everyday lives. In particular, mobile devices that we carry with us all the time and related multifaceted mobile services have increasingly occupied our life from work to leisure and from private to public. The shift of focus in HCI research has been from the traditional usability-centred view toward researching and designing for enjoyable and engaging experiences by highlighting the non-utilitarian aspects of interaction. The difference between usability and user experience is said to be about emotions: while good usability means lack of discomfort, good user experience means delighting the user [2]. Today the HCI field emphasises an approach to research and design for enjoyable and engaging experiences: 'Now it is no longer adequate just to avoid bad experiences; we have to find methods for designing good ones'.
