A shot thunders towards goal. At the last minute the ball takes a wicked deflection. For the goalkeeper it's an instant decision. A split second for their brain to analyse the direction and speed of the ball, to pull off a match winning save or leave their teammates in despair as the net behind them bulges.
Until recently, coaches training their keepers relied on nothing but their own perception to help goalkeepers refine their skills, but now the world of immersive technology is taking the process forward light years. Through head mounted displays units, virtual reality can now be used to analyse their performances in real time and to improve the way they respond to a variety of situations.
