It's no secret that Microsoft is working on a series of potential Xbox peripherals in the form of a Head Mounted Display (HMD) or glasses. In March 2012 we first broke the news that Microsoft filed for a patent relating to projector eyewear in the form of a helmet or glasses depending on the game or application. In June of that year we covered the optics behind their future eyewear and we covered this subject again in January 2013. And to make it real, we reported that Microsoft filed for a trademark application for "Xbox SmartGlass" covering "audiovisual devices" in April. Yesterday the US Patent and Trademark Office published Microsoft's latest patent in this project and our report extensively covers some of the sensors that Microsoft is considering for their eyewear. The second aspect of their latest invention involves a new invitational system for multiplayers who will own the new eyewear. Invitations will be simplified for those with the new eyewear. Gamers will be able to enter a new virtual area where you'll be able to interact with potential players. The invites could be simplified with natural audio invites instead of filling out forms and you'll be able to see the player that will be joining your game. All in all, if you're an Xbox fan and especially a multiplayer fan, you'll enjoy our latest report.
