Intel wants to retrofit the technology to existing vending machines so that different companies are able to study just what kind of people alongside their personalities and quirks are picking up their wares. An optical sensor is fitted to the top of the machine, enabling it to recognize the human face’s shape. This image will be fed back to a computer processor that does a bunch of calculations on the face, determining the shopper’s gender while categorizing them into one of four age brackets. Taking just a fraction of a second, this data will then determine what, if any, product should be served to the shopper. I wonder if putting a photograph up or wearing a mask would be able to fool the machine.
