"Swiss researchers have developed java software that has bluetooth-capable camera phones form a distributed camera network. Each phone shares information on visual events with its neighbours and can work out the spatial position of phones around it (pdf). The software will become open source sometime next year, and the creators say it could be used to make a quick and dirty surveillance system. 'The phones currently use the average speed people walk to guess the distances between themselves, based on how long people take to move from one phone's view to another's. In testing, the system determined the distances between each phone with about 95% accuracy. They were placed 4 metres apart, making it accurate to about 20 centimetres. In future, recording the speed at which objects pass by would make more accurate judgments possible.'"

TECHNOLOGY WAR?: Transform cellphones into a CCTV swarm — this would make it impossible for police to brutalize people at protests — too many phones …. THIS IS GOOD NEWS.

I’ve long had the idea for a distributed picture system, where any picture you take is uploaded to every device around you (and vice-versa), so everybody gets everybody’s pictures, and police can never take away the film. Cell phones
