no those glasses are basically just a video camera, there is no microphone and there is no voice recognition, etc.

as you can see in this link they cost $1500 and that is only for the video camera functionality.
in the new demo videos they have added a mic, voice recognition, the ability to take still pictures, stop and start recording, etc.
the early version which is the same as the picture above can only record video, and has no other functions as far as i can see.
so they managed to add all the other stuff, yet kept the design the exact same? also after adding all the additional stuff, imagine what the price now is of a model, even if the design is the same, your talking a glorified camera before and a fully functioning voice activated camera/ sat nav/ guide, etc.
the one in the new videos will probably cost $15K and look bigger than the one in the pic
you can clearly see in the video in my link the many users press a button on the glasses to start recording, basically its a camera on a set of glasses with a start stop button with a small overlayed screen
