A version will now enter mass production, thanks to a license granted to a UK firm. The camera is worn around the neck and takes an image every thirty seconds, or in response to its light sensor, accelerometer or bodyheat sensor indicating that something of interest may be happening. Until now only a few hundred had been made for research, which showed they can genuinely help people with memory problems. The new version will be marketed at Alzheimer's researchers this winter, and at consumers for "lifelogging" in 2010."
