Google goggles (Google Glass) have become famous even before being officially released and it looks like you are still adding features here and there to iron out the product before putting it on sale. The last one is quite interesting because it seems that the glasses will be able to send sounds directly to your head.
Instead of including a classic speakers, it seems that the glasses would be equipped with a vibration system that would act on the bones of your skull using them as amplification system. Say you would hear voices in your head the without external speakers or headphones and no one out there could hear what you're listening to.
The idea is rather curious on several levels, not only because it increases the level of privacy even while listening to music or someone during a telephone conversation. Besides that the device becomes lighter and more like ordinary glasses without attaching bulky headphones.
So far it seems that Google have patented the idea under the name of 'integral vibratory audio provides the user through the user's head.' A rather long name while descriptive.
Will have to see what other inventions added to the glasses before its release, but still many doubt it really ends up becoming a popular gadget to the level of a smartphone or tablet. Time will tell.
