Coffee Company, Douwe Egberts has gotten some press around their “Bye Bye Red Eye” campaign which places smart coffee machines in airports that dispense a free cup of coffee when travelers yawn. The vending machine employs facial coding technology which identifies yawns and other facial gestures to create a fun campaign that remedies tiredness. Tech like this can be used to trigger media and real world actions based on a variety of emotions using webcam software. While they have only served 210 passengers so far, this is more of a PR stunt for the Dutch coffee producer.
