Researchers modify refrigerator to stay locked unless you smile

Happiness counter

Developed by a group of researchers at the University of Tokyo, the team developed a device called the “Happiness Counter” that utilizes smile recognition to trigger specific actions. In order to test the device, the researchers attached the “Happiness Counter” to the front of a refrigerator and asked participants to smile each time they wanted to open up the fridge to grab something to eat or drink. Over a period of ten days, the researchers noticed that the participants shifted from a fake smile to a genuine smile in order to access food within the refrigerator.

Like many other digital camera brands, Sony includes a smile recognition function that will automatically take a picture when the people in the shot are smiling.

Nearly covering the LCD screen of the Sony CyberShot camera, the researchers attached a light sensor. When the camera automatically detects a smile and takes a picture, the light sensor picks up the flash of light and relays information that turns on the LED lights on the front of the device in the shape of a happy face. When the system detects someone that’s standing in front of the camera and isn’t smiling, the LED lights will create a frowning face in red.

Regarding real-world implementations, the researchers foresee workplaces could add the device to the door to a conference room and require employees to flash a smile in order to gain access to a meeting. Hypothetically, the researchers believe that this could influence the mood of the people attending the meeting and ultimately increase productivity. A spokesperson for the “Happiness Counter” device specifically stated “We feel that the happiness counter will naturally encourage the act of smiling in the multitude of daily frustrations, thus enhancing a positive mood and the communication of people.
