Thanks to the keen eye of 9to5Google, they noticed a new tech help FAQ by Google for the new Google Glass that has yet to be released to the greater public. The FAQ breaks down the technical specs in detail of what Google Glass encapsulates.
Some of the notables from the Glass Specs are a 5 megapixel camera (compare to the iPhone 5 with 8 megapixel). A bone conduction transucer, which allows you to hear sounds converted over from vibrations. It also has built in Wifi, Bluetooth, and 12gb of usable memory.
