For many years, hockey coaches have known that goaltenders focus on numerous moving objects while the opposing offense passes the puck from player to player. They surmised that the best goaltenders seamlessly switch from a focused, central vision to peripheral vision and back again. Instead of speculating from afar about a goalie’s vision and thought process, William Rahm, the goalie coach for Swedish Hockey League’s HV71, uses eye-tracking technology to analyze his goalies’ eye movements directly from their perspective.
“The most interesting results so far are to actually see what we think we know about how goaltenders process the game,” Rahm wrote to SportTechie in an email.
