Future: Billboards with Face Recognition

How long will it take for face recognition technology that has already found its way into inexpensive consumer electronics to be integrated into digital signage?

Check the specs on Sony Cyber-shot T200:

"Because the face makes the photo, Sony has created Face Detection technology that recognizes up to 8 faces in a photo and automatically controls focus, exposure, color and flash to bring out the best in everyone. Unlike some competitive systems, Sony Face Detection makes skin tones look more natural and reduces red-eye with pre-strobe flash.

In Smile Shutter Mode, the DSC-T200 helps you capture more smiles by shooting automatically when your subject laughs, smiles, even grins - only when focus is fixed. You select the person to watch and the expression to catch -- your Cyber-shot® camera’s Face Detection system and intelligent Smile Shutter algorithm do the rest!"

We know that the advertising applications are already in the labs: Last year, Microsoft showed off one such billboard.



  1. relevant analytics & metrics devices for digital signage networks has lagged behind other digital marketing tools. I've seen other devices that use facial recog to determine demographics and "eyeball count" but the elusive "what did the viewer do after they saw the digital message" still remains unanswered. Facial recog that leverages emotion tracking is a step in the right direction.

  2. Face detection and qualification (and not face recognition - which would infringe on data protection legislation in many countries) are no more lab applications. They're now being deployed in many European and Asian countries (check for instance what my company is doing up on www.quividi.com/references.html). Such systems make it possible to finely measure the audience of billboards and public screens (with Opportunities to see, real viewer counts, average attention times, etc. - all cross-referenced with what was on display at the moment people watched). They also let dynamic screens adapt in real time to the demographics of the viewers and to their head movements, for some natural interaction with content. That will let media sellers sell airtime like Google does with Adwords: advertisers will pay only when their ads is shown to the desired target, and they'll pay more for getting that person to start a dialog with them.
