The Collective Map

This game will show you randomly selected urban scenes and ask you where they are. In so doing, we capture your mental map - that is, which parts of the city you tend to correctly recognize. By combining your answers with other people’s, we are able to draw the collective mental map of the city.

Happy City

The collective map is important because it is associated with happiness. In his "The image of the city", Kevin Lynch showed that the happiest areas are those that are easily recognized and, as such, are prominent in people’s minds. By knowing which areas are difficult to recognize, we are able to recommend urban interventions to different stakeholders, including local government, urban planners and artists.

The Media

I'm feeling nerdy...

Fancy some graphs, p-values, and scientific jargon?
Here is the first scientific article for London
