one of the biggest issues with Google Glass is that it is very easily identifiable. alot of consumer businesses have banded the wear and use of Google glass in there establishment due to privacy concerns of their patrons.
but, what if you were able to have a recording device in a pair of glasses that looked like they were for regular wear. and, what if those glasses were somehow able to have Bluetooth connectivity, which you could link to your phone. someone could record audio and video that automatically connects to their mobile device for real time sharing of whatever the user is watching, without discovery and all the fuss of the current wearable glasses or camera option.
