The Google Glass project is something that Google seem very keen to push on with, as details have surfaced of the device at the FCC. Whilst it's certainly not a done deal that the hardware outlined here will be the final product which ends up on our shelves, we can at least gather some insight as to what Google have planned.
Google Glass will come equipped with a Broadcom 2.4GHz 802.11 b/g WiFi radio and a Bluetooth 4.0 + LE module. There was also another mention of the bone-conducting speakers. Although it's described as a “vibrating element” that transmit sound to the wearer “via contact with the user's head”, we can be pretty sure that this is the same technology which Google released some information about last week.
I'm sure many of you are aware of that odd phenomenon where your voice sounds different when you hear it back on a recording. Well that's because every time you talk, some of the low frequency energy produced from your vocal chords transfers through the bones and muscles in your body, reaching the ear ahead of the higher frequency reflections you'll heard from the room around you. It's this energy transfer property which the bone-conducting speakers aim to take advantage of, allowing you to hear without the need for an in ear speaker.
The conducting speaker also appears in a patent application for a “wearable computing device”, so it looks like Google Glass will probably end up using this technology.
Unfortunately there aren't any other juicy details available, but at least this tells us that Google Glass is moving forward, and could be making its way to developers in the near future.
