holy_calamity writes "Remember Microsoft's camera to be slung around the necks of people with Alzheimer's to help them recall where they'd been? A version of this device will now be mass-produced by a UK firm, Vicon, which obtained a license from Microsoft to manufacture the camera. It is worn around the neck and takes an image every thirty seconds, or in response to its light sensor, accelerometer, or body-heat 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 to Alzheimer's researchers this winter, and to consumers for 'lifelogging' beginning in 2010."
