Dubbed SenseCam, the prototype takes a snap whenever there is a drastic change in scenery. Boffins at Redmond want it to respond to other stimuli such as heart rate or skin temperature to track medical problems.
One day it could eventually link with other technology, such as face recognition to remind wearers when they have seen someone before.
Currently those using the prototype are using it to find where they left their car keys or interesting clothes they saw in a shop. µ
