Chapter eleven of the resource is now available in preview. It was written by Dag Svanaes, Professor at the Department of Computer and Information Science at the Norwegian University of Science and Technology (and former professor at Interaction Design Institute Ivrea) and deals with the philosophy of interaction and the interactive user experience.

“I will approach the question of interactivity from a number of angles, in the belief that a multi-paradigmatic analysis is necessary to give justice to the complexity of the phenomenon. I will start by defining the scope through some examples of interactive products and services. Next, I will analyse interactivity and the interactive user experience from a number of perspectives, including formal logic, cognitive science, phenomenology, and media and art studies. A number of other perspectives, e.g. ethnomethodology, semiotics, and activity theory, are highly relevant, but are not included here.”

Lengthy comments to Svanaes’ chapter were provided by Donald A. Norman and Eva Hornecker.
