Abstract [en]

This thesis explores the relationship between usability and persuasion in the design of the interface for a smart-phone application. Using a usability study of an I-phone app combined with interviews with users and the designers, the roles of usability and persuasion in the design of the app and their influence on each other as design goals is discussed from both the users’ and designers’ perspectives. The application’s purpose is to support behavior change in users by giving them feedback on their electricity use in order to encourage them to switch their pattern of usage to reduce CO² emissions. This thesis should be of interest to interaction designers faced with the challenge of designing interfaces that are simultaneously both user-friendly and persuasive. While it is generally accepted that usability has a positive effect on the potential of a design to be persuasive little is known about the effects, if any, of persuasion on usability. This thesis proposes that the relationship between these two design principles is more complex than is generally assumed and that in certain situations they may even be traded off against one another.  This trade-off could be useful for designers framing design challenges involving usability and persuasion.
