[Research] just fell on this FLIRT thing...
This flirt projects seems interesting:
A European Comission project under the 'IT for Mobility' theme. The development of digital cellular structures by the mobile communications industry has generated a genuine fusion between information space and urban territory. City location, time, day and date can all shape relationships to information sources. The tight constraints of mobile displays, juxtaposed with the spontaneity, unpredictability and transcience of everyday mobility, requieres a fresh approach to how this relationship might work.
FLIRT investigates the potential of location-specific information, not only as an information resource, but also as a medium for social interaction and play.
FLIRT is a collaboration between Philips Research Laboratories UK, Philips Consumer Communications France, Helsinki Telephone Corporation Finland, Infogrames Entertainment France and the Royal College of Art UK.
