Inventing laughter gauge

Japanese professor Yoji Kimura believes that laughter is a weapon that can end a war. Only thing is how to measure it. So, he created a charting machine and set the unit for laughter.

"We found children laugh more comfortably, making 10 aH per second, twice as big," Kimura said at Kansai University in Osaka. "Adults consider it appropriate to laugh and under those barriers, they sometimes forget about laughter."

Kimura added, "Laughter is like the computer's reboot function. Laughter is very important to human evolution." He has studied laughter for several decades. According to his hypothesis, human laughter has gone through four stages of emotion - relaxed, escaping norms, laughing and laughing.

To measure laughter, he attached sensors to the abdominal skin of the subject, the diaphragm, to check for muscle movement. By examining the movement of the diaphragm and other parts of the body, the machine will know whether a person is pretending to laugh and distinguishes between laughter and ridicule.

Kimura plans to compact the device with a mobile phone and offer it as a medical device.
