Bet you didn't think throwing on a pair of ultra-nerdy lab glasses could help your memory, did you? These smart video goggles, developed by researchers at the University of Tokyo, record everything in front of them.
The Cyber Goggles create footage of everything the goggle-wearer sees, the content is then analyzed, labeled and stored in a searchable database. Imagine how easy this would make it to retrace exactly where you placed those keys, or if you actually did remember to lock the car. All you'd have to do is type in a key word like "key" or "car" and it will be able to pull up the info for you and ease your panicked mind.
All of the recorded video is stored in a small computer which is worn on your back.
