"...just by walking down the street you could be subject to a personal biometric system, you could be scanned by the gateway of the transit system, there could be something embedded in the street or in the flooring beneath you... you could be touching other tangible interfaces in the environment around you... the lamp posts and the other features of the streetscape could have informational services... and last but not least there's the surveillance element, there's a UAV, a robotic helicopter which is also surveying the cityscape and communicating with all of these devices... This is really what I mean by a transformation of the relationship between user and device. This person is not a user anymore in any real sense of the English world, they are a subject."
