Real-world ads that know if you looked at themNICK DOUGLAS — A huge advantage of online ads is knowing just how many people saw (or at least loaded) an ad. No more, if Xuuk Inc. (voted "Most likely to become an H.P. Lovecraft monster") succeeds with the eyebox2, its new thousand-dollar camera that counts viewers from up to 35 feet away. The camera, which collects no data about viewers, could be used on racks of products too. If Google doesn't buy Xuuk or a competitor by January (I'm pretty sure Wired News is wrong about Google already buying the device), I'll take everyone to lunch.
