Will Pay-Per-Gaze Advertising Reach Google Glass?

Hard to imagine it will not:

Google will use Glass to make money from advertisers, -that much is beyond question. PPG is about the least obtrusive (for the user) form of generating this revenue if it can be worked out. It places an emphasis on developing more compelling real world ads as opposed to injecting pop ups or more traditional HUD messaging.

The cool thing for advertisers is that you would only need a statistically significant amount of Glass users to give you localized feedback in order to iterate real world ads for far more people than are doing the measuring.
