A method for analysing emotion and motivation in requirements engineering (RE) is described. The method extends personal RE where requirements are for individual users and their needs. Theories from the psychology of emotion and motivation are introduced and applied in a top-down pathway motivated by system goals to influence users, and a bottom-up scenario-based path to analyse affective situations which might be produced by user-oriented RE. Use of agent technology in storyboards and scenario analysis of affective situations is described and illustrated with case studies in health informatics for persuasive technology applications.
