Hannah is interested in the city and how technology is changing our public, private and personal relationships within it. She talked about the following themes, how CCTV watches our every move. Mobile Phone data can be extracted by the police without permission. Interactive billboards film crowds and feed their images back to them with adverts. Secret cameras monitor who is paying attention and for how long. Interactive vending machines measuring your height, weight and gender. She wonders what are we to think of this non-consensual data? Personalisation is the pay off, it’s convenient, but should it make us nervous?
