How Computer Graphics Without Screens Can Breach Sports

As recently as October, we mused about the possibilities of augmented reality in sports, and I concluded with a brief story about some strange display technology my grandfather encountered in the 1960s — a device that could purportedly display 3D images without 3D goggles. I have always had trouble conceptualizing that idea. How to you make light stop mid air? How can you create a hologram without some sort mist or substance to reflect the light in transit? Well, I dunno. Maybe it’s not possible.

And maybe this:

This technology could be significant in many ways. It could illuminate the ball path for a touchdown throw, a three-pointer or a fastball on the outside edge for fans in the stadium (not to mention umpires and referees). It could show a glowing yellow line for the first down marker that more than just the audience at home could see. It could change the role of a scoreboard as we know it.

Obviously, glittering dots in the sky are a long way away from an illuminated pitch tracker. But computers went from singing Daisy to World is Mine, this, in under 60 years. We cannot say where this current technology can and will end.
