Sony Glasses track eye movement and capture what you see!!

Sony Computer Science Laboratories, in collaboration with the University of Tokyo, has developed a lightweight device that can able to tracks the user's eye movement and also it can record what you are seeing through your eyeball.

The glasses consist of an infrared LED lamps and receivers inside, and a camera on the outside that records what the user sees.

It works by directing an infrared light to the user's eyeball. Photoreceivers detect where the light bounces off, determining the position of the pupil. The system then tracks the user's gaze and films accordingly. A little blue light on the camera indicates that it's filming.

The system logs everything the user looks at, and it can even recognize English characters, so it can determine what a user is reading -- like a sign or a book title, for instance.
