NO WORD ON HOW MANY GUFFAWS THE SENSORS THEMSELVES PROVOKE.
"Researchers at Kansai University have developed a machine that can scientifically measure the quantity of a person’s laughter, as well as distinguish between the real and the fake. The sensors, which attach to a person’s cheeks, chest and abdomen, take 3,000 measurements per second. Sensor data is relayed to a computer, where it is analyzed by special software that determines the nature of the laugh and assigns a numerical score based on the quantity."
