Ditto. The NFL will in particular would be a prime candidate since sports fans are already dying to be in the athlete's shoes (though not have athlete's feet).

Ditto. The NFL will in particular would be a prime candidate since sports fans are already dying to be in the athlete's shoes (though not have athlete's feet). The one hiccup in this would be safety. In the off chance a ball or another player's hand (they're not supposed to grab the shield or helmet, but it happens) crushes the device or worse, drives it into the player's eyes. They would need some sort of built-in thing if that's the case and I'm sure that the NFL will have rules against putting cameras on the back of the helmet so the player can keep an eye there.
