An exploration of user engagement in HCI

Engagement is a concept of the utmost importance in human computer interaction, not only for informing the design and implementation of interfaces, but also for enabling more sophisticated interfaces capable of adapting to users. While the notion of engagement is actively being studied in a diverse set of domains, the term has been used to refer to a number of related, but different concepts. This paper represents a first attempt at exploring a number of important concepts that the term has been used to refer to, of relevance to both human-human and human-machine interaction modelling.
