Google Glass

Future Glass from Google


Google glass is one of the most important projects of the Google and which is investing a lot of time and money to go ahead with this augmented reality device that could well use Tom Cruise in "Mission Impossible."With constant delays, it seems that will be released soon at a price of $ 1,500. The purpose of Google Glass is to display information available for users of "smartphone" without using the hands, also allowing access to Internet using voice commands.

The Internet giant posted a video illustrating the potential of this glass device. The augmented reality glasses from Google may still reserve a surprise to its future users. A last minute patent has revealed that it is possible that these will not transmit the sound with a conventional headset, but by vibrations through the skull bones. This technology is known as 'bone conduction'.

A patent search reveals that the device will use vibration arises due to head contact to transmit auditory information in augmented reality glasses.

Sound travels through the air in the form of pressure waves. The oscillation in turn transmits vibrations to the cochlea, the place from which electrical impulses are sent to the brain. Bone conduction headphones, meanwhile, used the bones of the skull to transmit sound vibration information. As the final destination is the same as the inner ear will not see many differences.

Bone conduction headphones have some advantages over the conventional ones. The bottom line is that no other block outside sounds. With this technology, Google Goggles could allow its users to send their messages without stopping to hear the outside world of traffic, a conversation or even a song. Also do not damage the ear, and transmit clear sound no matter how noisy the surroundings. For some years there are teams that use this technique.

Its main disadvantage is that they are not as effective at conveying the sense of sound space. While conventional headphones can exploit fully the properties 'stereo' of a song-and that can place each instrument in-place, the bone conduction are more difficult to do so.
The transmission of sound through the skull bones is usually done by emitting vibrations between the temple and jaw. Although it is not clear in the text of the patent-which are always cumbersome-the Glass Google could use this area, or who is behind the ear, to conduct audio output.

The aim of Glass Google is to bring augmented reality to the public. The Californian based search engine presented this project in last June at its annual conference for developers. They are a kind of overlay-glasses that allow non-intrusively-relevant information about what your user sees. This latest patent suggests that the Silicon Valley giant wants this gadget-whose first prototypes are about to distribute a minimum-interference in the daily lives of its users.
