Google counting real-world ad impressions.

Reportedly your favorite big brother, Google, is looking at the feasibility of using IR-emitting cameras to count how often people look at physical advertising spaces. Then the advertiser can only pay for their actual impressions. We’ve done some close up work on eye and gaze tracking with infrared in our laboratory but it sounds like they are getting them to work from a bit further away, but certainly not for roadside billboard distance yet.

I was just thinking though, what if the advertiser wasn’t very good at designing eye-catching billboards, and nobody looked at it? The advertiser isn’t getting many impressions, but they also aren’t paying much. What about the poor person who rents the billboard space? Maybe they have to set an interestingness threshold.

Open source real-time gaze tracking

Looking for a cheap gaze tracking solution?

The purpose of openEyes is to provide a hardware design and a set of software tools useful for the analysis of eye movement data. The development of openEyes stems from the recognition in the eye tracking and human computer interaction communities that while the cost of hardware for eye tracking has precipitously dropped in the recent past that the there is lack of freely available software to implement even long-established eye-tracking methods. The tools available for this platform include algorithms to measure eye movements from digital videos, techniques to calibrate the eye tracking system, and example software to facilitate real-time eye-tracking application development.
