When VAR comes in I've invented a gadget to aid in the ref reviewing an incident without having to run over to a screen on the sideline.

They carry foam spray, cards, a pen and a whistle. Some kit when you think about it.
Soldiers do long marches carrying Bergens, some weighing 60lb or more, plus a helmet carrying visual gadgets and such.

Where am I going with this?

Ok, the ref wears a helmet with a 20 inch flat screen on top (can be made to be bigger for the ref's with bad eyesight) , which will be a waterproof TV and would be attached to it. This will be on an automatic hinge that will be operated with a remote control worn as a a snazzy ring, which will be voice activated with a special code word. Something like, " drop the TV screen so I can see that last incident and make things a lot quicker in making a correct decision to aid in the course of this 90 minute, plus added time, game"....or maybe a shorter code word.

This will immediately drop down the screen in front of his/her face from it being a sort of university mortar board hat looking thing, only much larger, in front of the ref who will end up looking like some kind of robot when viewed by fans and players looking at the back of the screen.

I'd appreciate some feedback on this before I hand in the prototype to FIFA.
