To capitalize on the lead up of the 2014 FIFA World Cup, Brazilian fast food chain Giraffas created a mobile game that turned their tray papers into a virtual soccer field. To play, the consumers had to rip the side of the paper tray, make a paper ball and flick it into their mobile screens. 😎
7 million tray papers were printed and the game was made possible by using the smartphone camera to recognize the ball distance, accelerometer to identify the trajectory of the kick and the microphone to recognize the area of the impact.
