Via anne, I fell on this Urban Tapestries project. This is “a framework for understanding the social, cultural, economic and political implications of pervasive location-based mobile and wireless systems.”.
They built “an experimental location-based wireless platform to allow users to access and author location-specific content (text, audio, pictures and movies)”. This space is seen as “a forum for exploring and sharing experience and knowledge, for leaving and annotating ephemeral traces of peoples presence in the geography of the city.”
This project, very relevant to my thesis, deals with the concept of Social Navigation. The authors are more interested in the social and politics impacts. I would prefer to deal with cognitive and social issues at a micro level (team of 5-10 people).
