Is every moment of your life worth recording? The researchers of the SenseCam think so. The camera, which is worn around the neck like a pendant, snaps a photo every time it detects the body heat from someone else in front of the wearer. Initially created to help those with Alzheimer’s disease to remember, the SenseCam may soon allow everyday people to chronicle their life’s events. Developed by Microsoft Research Cambridge, U.K., the technology has been licensed to Vicon, another U.K.-based company. Expected to retail for about US$820, Vicon’s version will be marketed to researchers at first. A consumer version could be on the market as early as 2010.
