The potential importance of human affect during human¬†–¬†computer interaction (HCI) is becoming increasingly well recognised. However, measuring and analysing affective behaviour is problematic. Physiological indicators reveal only some, sometimes ambiguous information. Video analysis and existing coding schemes are notoriously lengthy and complex, and examine only certain aspects of affect. This paper describes the development of a practical methodology to assess user affect, as displayed by emotional expressions. Interaction analysis techniques were used to identify discrete affective messages ‘affectemes' and their components. This paper explains the rationale for this approach and demonstrates how it can be applied in practice. Preliminary evidence for its efficacy and reliability is also presented.
