Tencent Digital (translated: Xiao Xiawen) July 31 news, looking at the picture above, will it remind you of a horror movie, but it is not, it is a facial detection system that senses the expressions of users in the camera. The use of this system is also very special, even embedded in the coffee machine.

This is the idea from the Dutch coffee company Douwe Egberts, which has added facial recognition technology to its coffee machine to provide free coffee to users, and the machine is placed in a corner of the airport full of tired travelers with red blood in their eyes.

The name of the event is also interesting, called "Goodbye Red Blood". It has served more than 210 airport passengers, most of the coffee is free, and of course, users have to "pay" a yawn. That's what facial recognition technology does. All you have to do is yawn in front of the coffee machine and a cup of warm coffee will appear in front of you. Isn't it interesting?
