What is 'psychogeography', who does it, how do they do it, and with what results?

If you have seen someone walking purposefully across your local cityscape in the last few months wearing a little more than the usual earphone headset, it could have been Daniel Raven-Ellison, psycho-mapping one of the UKs 63 cities. He has been creating an emotional-response map of Britain, at the cutting edge of 'psychogeography' - our psychological response to 'place'. His headset records brain activity and measures his emotional response to sights, sounds, even smells as he plots a course across a city transect. The resulting map is more a personal sensory visualisation of his exploration rather than objective metrics. But then, many of our decisions and attitudes are shaped more by our subjective responses to place, than cold, logical facts.
