The Remote Cheerer system developed by the Japanese firm Yamaha allows fans following the match on TV, the radio or online to encourage – or berate – players via their smartphones, their voices reverberating around the stadium in realtime via loudspeakers.

In a recent field test, users in multiple remote locations chose from a range of on-screen options that sent their cheers, applause, chants and boos into the 50,000-seat Shizuoka Stadium Ecopa via 58 speakers set up among the empty seats.
