There's something wrong with translating an article about something occurring in my own country, but hey...Yomiuri is a large newspaper, so there's no reason why they couldn't find out about something before other American sources.
Thus the reason I'm posting this article - I don't see it anywhere else yet. Not a direct translation (yet), but I promise my article will contain the same information.
Anyway, it's about being able to tell what someone is looking at by recording a high resolution image of their eyeball.

A team at the University of Columbia has developed technology to use high resolution digital cameras to record what is being seen by a person's eyes. (No, this doesn't work by embedding cameras inside eyes, go away Shadowrun.) Instead, it works more along the lines of things like being able to tell what a person in an old photograph is looking at, or being able to extract important information such as where terrorists are based o­n the reflections (in their eyes) of declarations they are reading.

Professor Shree Nayar and Dr. Ko Nishino of Columbia University intricately analyzed the relationship between the reflections o­n the cornea of the eyeball and the image actually perceived by the retina after passing through the pupil. The curved reflection o­n the cornea is recorded with a 6MP camera, and is then restored to a flat image; what the person was looking at can be extracted from this image.

In experiments, it was said that the system could successfully extract an image from the cornea so that o­ne could tell what ball a person was aiming at o­n a pool table.

The results will be announced at the "SIGGRAPH" conference going o­n from August in Los Angeles.
