Dutch coffee specialist Douwe Egberts has created a vending machine capable of detecting facial movements and recognizing a yawn, which prompts the machine to fill a cup of coffee for the yawner.
The yawn-activated coffee machine has been deployed under a Douwe Egberts campaign called "Bye Bye Red Eye" at the O.R. Tambo International Airport in Johannesburg, the busiest in Africa.
The machine detects yawns using a combination of sound and facial recognition software. The software monitors and detects various aspects of
the human face and also includes volume settings. If the weary traveler’s mouth is open wide enough, a certain level of noise is registered, triggering the machine to serve up a cup of coffee.
