I was just looking at QUIVIDI online (the company who supplies the facial recognition technology for the vampire diaries interactive street ad - previous post)
I came across this article entitled "PRESENSIA AND QUIVIDI INVENT THE FIRST GENDER-AWARE FRAGRANCE DISPENSER"
worth a quick look: http://www.quividi.com/news/090107/
New technology really has taken advertising far beyond traditional methods.
Anyone seen anything like this in use?
