The gaming world certainly isn't without its crazy patents and, today, we see Microsoft add another to the pile. The patent in question is a "laser-scanning virtual image display" able to display an image very close to a user's eyes. Specifically, two such displays would be incorporated into a helmet, allowing a user to see a stereoscopic, three dimensional image. While not exclusively meant for video games, the patent does mention that the helmet could "be used in applications ranging from video gaming to aviation."
Furthermore, as spotted by Patent Bolt, the displays "may be at least partly transparent," which would allow the user to see the world around him as well as the projected image. That's good, because we prefer our pilots to keep their eyes on the sky, thank you very much.
