We have been looking at the subject of 'urban interaction'. I got the understanding that this is pretty much an explanation of anything which involves interacting and communicating somehow with others in a public environment- examples of this could be through transport networks, time based gaming, geocaching etc. 

We created a task for another group of students to complete when in Bradford. We asked them to follow the marked out word (Bradford) on the map, not straying at all from the marked route. Whilst they were in each part of the route, they had to take 1 photograph of a sign/poster, or anything similar, that included that letter. Giving someone this game is not only a way of collecting photographs from an unknown area, but also leading them around a new city.
