Google officially has published a list of technical specifications for the head-mounted device, alongside the first details of its mirror API for apps. These are the specs:
Display & Camera
The Glass its self features a 640 x 360 display that Google claims is the “equivalent of a 25-inch high definition screen from eight feet away,”. On the camera font, expect a 5-megapixel camera capable of 720p video, plus audio that comes via a bone conduction transducer.
Memory & nose pad
There will be 16GB of flash storage on-board, with 12GB actually usable, and it will sync with “Google cloud storage” we assume its Google Drive. Glass also comes with changeful nose pads in a frame that Google says will “fit any face,” and you’ll get extra pads in two sizes.
24 hour battery life
Google says battery life for glass will last up to “one full day of typical use,” though notes that certain applications such as video recording and Hangouts will have a greater impact on battery survival.
While Glass charges over a Micro USB connector, Google encourages owners to use the packed-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 functionality will vary. The list of specifications also mentions an app called “MyGlass” for phones with Android 4.0.3 and above; this will enable GPS and SMS support.
