Microsoft recently filed a patent for augmented reality (AR) glasses that would allow users to play multiplayer games in real space with each other, according to documents from the United States Patent and Trademark Office (uncovered by NeoGAF). The patent covers not only the technology of the glasses, but also a system for player matching and information that the glasses would collect.

The filing includes patent art from the perspective of two boys wearing the glasses while sword-fighting in augmented reality over “Jane Smith (The Queen)” as the user decides between games including Dance, Tennis, and “search and find.” In the system Microsoft describes, users send voice invitations to play a game via the glasses, and then the glasses use eye-tracking, facial recognition, depth information, and “device information” like gyroscope or accelerometer readings to conduct the game.

A leak last summer suggested that AR glasses were part of the long-term trajectory of Microsoft’s upcoming console, the Xbox One. The leaked PowerPoint showed that the company intended to first launch the console, then a pay-TV service, then “Fortaleza” glasses that would not only work with the console over Wi-Fi but would present AR experiences in the real world as a mobile device via Xbox Live.

The roadmap suggested that these AR glasses would not appear until some time in 2015. That’s two long years before we can challenge real people to virtual swordfights over a real, but also virtual, queen.
