One Barcelona comedy club is experimenting with using facial recognition technology to charge patrons by the laugh.
The comedy club, Teatreneu, partnered with the advertising firm The Cyranos McCann to implement the new technology after the government hiked taxes on theater tickets, according to a BBC report. In 2012, the Spanish government raised taxes on theatrical shows from 8 to 21 percent.
Cyranos McCann installed tablets on the back of each seat that used facial recognition tech to measure how much a person enjoyed the show by tracking when each patron laughed or smiled.
Each giggle costs approximately 30 Euro cents ($0.38). However, if a patron hits the 24 Euros mark, which is about 80 laughs, the rest of their laughs are free of charge.
