Affective states have become a crucial part of human–computer interaction research. Many studies have analysed the impact of the technology on the users' affective states as a part of what is called user experience UX. We consider the impact of antecedent affective states on interaction with a technological artefact. We induced positive and negative affective states using film clips. Then we analysed the impact of affects on the subsequent interaction with a tablet PC. Results show that positive and negative affective states have different emotional activation patterns. Positive affect was more sensitive for changes in tasks and experimental setting. In addition, these activation patterns affected behaviour for a short time only. These findings are discussed against the background of research into UX dynamics, dynamics of affect, and user-centred design research.
