Long-range Eye Tracker Enables Selling Ads 'By The Eyeball'
Science Daily — A Queen’s University Computing professor’s invention – recently unveiled at Google’s corporate headquarters in California – provides a unique, affordable way for advertisers to track the effectiveness of their messages by measuring how many people are looking at their billboards and screens.
Called eyebox2™, the portable device uses a camera that monitors eye movements in real time and automatically detects when you are looking at it from up to 10 meters away, without calibration. Until now, such eye-trackers have been ineffective beyond 60 centimeters, required people to remain stationary, needed personalized calibration to function, and cost more than $25,000 US. By contrast, the new walk-up-and-use eye is offered at a fraction of that cost.

“Our technology allows interactive real-time “Flow of Attention” measures of customers in the real world. This allows ambient ads run in malls literally to be sold ‘by the eyeball,” says Dr. Vertegaal. “It enables brick-and-mortar stores such as Wal-mart and Sears to use a revenue model similar to Google’s online PageRank and web analytics technologies.”
