Google patents ‘pay-per-gaze’ eye-tracking that could measure emotional response to real-world ads

Advertisers spend heaps of cash on branding, bannering, and product-placing. But does anyone really look at those ads? Google could be betting that advertisers will pay to know whether consumers are actually looking at their billboards, magazine spreads, and online ads. The company was just granted a patent for “pay-per-gaze” advertising, which would employ a Google Glass-like eye sensor in order to identify when consumers are looking at advertisements in the real world and online.
