Google has published the list of technical specifications for Google Glass.
Glass features a 640×360 pixel resolution display, which apparently is equivalent to a “25 inch high definition screen from eight feet away.”. A 5mp camera which is capable of 720p video recording, audio that comes from a bone conduction transducer. It will have 16GB flash storage on board, 12GB is actually usable and that will sync with “Google cloud storage”. Google says Glass will “fit any face” with adjustable nose pads, you will also get extra pads in two different sizes.
Google claims that Glass will last up to “one full day of typical use,”, but certain applications will eat more battery life, like video recording and Hangouts. Glass charges over Micro USB and Google encourages owners to utilise the pack-in USB cable for a “long and prosperous” life. Glass supports 802.11b/g Wi-Fi and is compatible with “any Bluetooth-capable phone,” though, some phones will support more functionality than others. The web-page also mentions an companion app for Android, dubbed “MyGlass”. It is made for phones with Android 4.0.3 and higher.
