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.
