Week SIX

Part IV of Hornbæk et al. (2025)

Intro

So far we’ve looked at generalizable properties of humans and how we can understand specific users. Soon we’ll look at engineering and the design of the machine. Interaction is the space in between the human and the machine.

The concepts this week all commit to the idea of mutual determinacy: what happens cannot be attributed to the person or the machine alone.

This week’s question: if “interaction” covers everything from a keypress to adopting a system across an organization, what good is it as a concept, and which theory do we reach for when?
