Microsoft may have their own Project Glass in development
In the meantime it appears that Microsoft have their own version of Project Glass on the way. The news came to light from a Patent Microsoft had applied for.
Unlike Google’s version, which is planned to be worn all the time, Microsoft appear to want their device to enhance live experiences such as sports or concerts. This would consist of text and audio overlays to the event as you watch it.
It seems to be a bit more of a realistic approach than that of Google’s Project Glass.
