Individuation and Diversity: The Need for Idiographic HCI

Abstract

Nowadays, our life is characterized by an increasing complexity and variety in the use of technology: highly idiosyncratic experiences in technology use have become rule rather than exceptions. Such “normal” variety has an impact on the field of Human-Computer Interaction by posing a new challenge, that of ‘individuation’, i.e. passing from research and design for the ‘average user’, to research and design for ‘individuals’. We maintain that HCI is in the middle of such a transition and that it should actively develop proper means to address the complexity of idiosyncratic uses of technology. Such a transition will mark a shift from ‘nomothetic’ to ‘idiographic’ approaches.
