Sometimes you go to a comedy movie or play, but you after that realize that show doesn't deserve your attention and you wasted time and money, but, what if you wan only pay when the show is really funny.
A new cinema experience is applied in Spain, and it will let you pay just per number of outloud laughs ! every spectator has a tablet in front of him, and using facial Recognition, an installed software can tell how many times you laughed, an based on that number, you will pay you ticket, the laugh price was about $0.2. After making the experiments, statstics show that the ticket price was variating between $5 and $20, and that's not bad !
In the future, maybe a new way will be implemented in horror movies to count the number of times you were really frightened !
