The glasses will also merge the real and virtual world. This means that when you play a virtual game at home while wearing them, the glasses recognize real word obstacles like a chair or a table, and show them on the screen so that you can avoid them.
The interesting thing is that this patent pretty much confirms that Microsoft is working on a competitor to Google Glass. Back in November 2012, word first slipped out that Microsoft was working on connected specs. Nearly a year later, the rumor came up again. Now, with the publication of this patent application, it would seem that the crew in Redmond is working hard on its own pair of augmented reality smart glasses.
