Flozzin writes with news that documents published
to the U.S. Federal Communications Commission's website have provided new details about Project Glass, Google's augmented-reality headset
"A test report describes video playing on the device alongside audio running to a 'vibrating element.' The description tallies with a patent filing suggesting it plays sound via 'bone-conduction' tech rather than earbuds. Developers are due to receive a test edition of the headset later this year. ... [The FCC's papers] describe data being sent to the small screen display via wi-fi and Bluetooth using a radio unit manufactured by Broadcom. The equipment is also said to be able to store video files internally and can be recharged by plugging a power connector into the computing unit on the right-hand arm of the glasses' frame. However, the most arresting detail is the suggestion that audio is provided without the user needing to wear headphones which might disturb how they hear ambient sounds. Last week Google filed a patent application entitled Wearable Computing Device with Indirect Bone-Conduction Speaker."
