Japanese Scientists believe they have invented a device that could make losing your car keys a thing of the past. They are Smart Goggles, which record everything the wearer sees and can memorise where objects are.

The glasses, developed by a team from Tokyo University, use what is said to be the world's most advanced object recognition software. This can locate the last time an object was seen if it is misplaced, and replay the footage. An experimental model has been developed which is too large for everyday use, but the team says miniature versions are on the way. The only problem then will be what to do if you lose your glasses!
