Military Glasses

In Defense One, an example of 'military glasses'.  How are these different from Google Glass?   First with more of an emphasis on usable, task oriented augmented reality.

" ... The glasses, called simply the X6, are from San Francisco-based Osterhout Design Group. They look like the lovechild of Google Glass and the Oculus Rift, providing more information to the wearer than the small window on Google’s much-maligned headset but not obstructing vision like the Oculus Rift. (Admittedly, for spy glasses, they lack a certain subtlety.)

At a recent innovation symposium at Defense Intelligence Agency headquarters in Washington, D.C., Bobby King, vice president of special projects for Osterhout, demonstrated how the headset provides situational intelligence.  Defense One looked through the glasses at a static, two-dimensional map and suddenly structures appeared in three dimensions related to objects of interest. King confirmed that the map was just a regular print of a satellite photograph. With that particular app, the glasses send information to a server that then processes the image against others to determine the location depicted. The glasses then present data from the database visually in the form of structures, special instructions, clues, etc. The view was smarter and more useful than what you would see with Google Glass, but didn’t get in the way of the user’s ability to actually see, like a clunky virtual reality headset. ...
