For the first time centre referees would be wearing an headset, and this has been described as a revolutionary Video Assistant Referee by FIFA.
FIFA confirmed that the VAR headset which has been tested would officially be used at the World Cup in Russia.
FIFA on Saturday gave a thumbs-up to the device designed to speed up controversial video decisions.
Instead of referees rushing to view a pitch-side TV, they would be able to see VAR images instantly on a 3D digital screen. Boffins at electronics giants Sony came up with the idea to combine real pictures with virtual-reality.
The device has a built-in grid-work of digital lines which relates with the turf would allow refs to make accurate offside calls while a unique motion scanner can also detect players diving — all in real time.
