It seems that facial recognition technologies are becoming more and more appealing for the advertising industry. We have known products from NEC and Quividi, now more companies are joining the game, e.g. TruMedia Technologies and Studio IMC. The gender and age aware signage systems they sell are able to target specific ads to certain audiences - so called “proactive merchandising”.
Such technologies are not yet as mature as people may expect. For example, Quividi's system is said to be accurate 80-90% of the time for gender; it can only categorize age in broad ranges — teens, younger to middle-aged folks and seniors; and they admit that determining ethnicity is even more challenging.
Anyway, it is a rising market and we must keep an eye on it.
