A little while ago, Sony Computer Science Laboratories, Inc. presented a device that could easily be mounted on glasses in order to track the movement of the human eyes. Not only is it small and compact, but the gadget also integrates English writing recognition technologies. Though only a prototype for now, it promises some serious lifelogging in the future.

Also involved in this project is the University of Tokyo, which works together with Sony CSL on this lifelogging solution. The idea to equip glasses with the technology was Sony's and the result can be seen in the picture I got from Tech-On.

While the device integrates special lasers capable of tracking eye movements, it also has an exterior camera, which records every object the user is interested in. By combining the data from the LED lamps with that of the camera, these glasses will one day be able to tell the whole world what type of food you prefer, how often you gaze at girls in mini-skirts, or whether you need subtitles when watching a movie.

The infrared lights are directed at the eyeballs of the wearer and the photoreceivers detect the light coming from the eyeball in order to locate the exact position of the black part in the eyeball. The data is sent to the camera placed on the exterior of the glasses and this way, all your points of interest are recorded. As I have told you before, the mini-system is capable of recognizing English language characters, so your lifelog will also contain books you read or newspaper articles.

This prototype is still waiting for some improvements, such the integration of GPS, while a major commercialization issue regarding it is the power supply. I am sure Sony CSL will make the official announcement as soon as it is completed.
