This week I introduce the module. We start off with a short history of the evolution of computing over the decades. Next, you'll hear about how mobile phones have become the dominant ubiquitous computing technology. The main part of the podcast finishes by introducing some of the kinds of 'ubicomp' research that we're going to touch on throughout the module. As this podcast will, hopefully, get you moving, I thought it'd be good to finish the episode by talking to Prof Anna Cox from the UCL Interaction Centre about the effect that the pandemic has had on our activity levels and how technology can help us get moving.
