Scientists at the University of Tokyo have developed a device that makes a fridge door much easier to open when people smile at it.
Scientists at the University of Tokyo have developed a device called a ‘Happiness Counter‘, which can be attached to a refrigerator door to make it easier to open if the person is smiling. The system scans your face as you stand in front of it and if you are frowning, the door will be difficult to open. It is designed to naturally facilitate smiling in our daily life and is mainly aimed at people living alone.
The Happiness Counter combines visual smile face recognition, user feedback, and network communication. You can see it in action in the video below:
