“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.”
Finally, a piece on interaction design with more deep thoughts than normal.
