There's been some buzz recently about how the Dallas Cowboys are training their quarterbacks with virtual reality technology. Re/code has more information:
"The Cowboys have inked a two-year deal with StriVR Labs, a virtual reality sports startup, to train all of its quarterbacks using a VR headset, according to a source familiar with the deal. After donning the headset, players see a live-action 3-D video replay of a football play from the quarterback’s perspective, and can review that play from a first-person view over and over, looking in any direction.
Currently, StriVR’s technology is not interactive, but instead aims to teach quarterbacks decision-making skills in the context of a real play.
