Designing User Interfaces in Emotionally-Sensitive Applications

A method for analysing emotion and motivation for design of affective user interfaces is described. Theories from psychology of emotion and motivation are applied in user-centred design to analyse desired influences on users, and plan appropriate UI features, based on a scenario-based approach that analyses affective situations. The method informs design of multimedia and agent-based user interfaces for persuasive technology applications and domains where the user interface may have emotive effects. Use of method is illustrated with a case study in health informatics for a persuasive technology application.
