Google Glass wants to track how you watch ads

An attendee tries Google Glass during the Google I/O developer conference on May 17, 2013 in San Francisco, Calif.

This final note today, in which Google's quest to take over the world moves another step forward.

I direct you now to the U.S. Patent and Trademark Office -- specifically patent number 8,510,166, issued 10 days ago for a "Gaze Tracking System."

Or, to paraphrase, Google Glass is gonna be watching you while you're watching it.

And then how about this, buried deep down in the fine print: A pay-per-gaze advertising system.

The thing's gonna measure pupil dilation so see how invested you are in the ad.
