In 2014, a Google Glass device was strapped to the head of tennis legend Roger Federer as he played a game on the court. Among the Glass’s many features, it enables wearers to take pictures or video of whatever stands in their line of vision, activated by a simple tap or swipe across the side of the device, or by voice command. As the smart computing device sat across Federer’s face like a pair of eyeglasses, it was set to begin recording. The resulting one minute and twenty second video, shot at Google’s facility in Mountain View, provides a striking glimpse of the game from Federer’s point of view. It is difficult not to marvel at the intense velocity of play captured in the shaky-cam footage.
