Google’s Project Glass is an interesting product due to its mystery but also because of how “unsecretive” they really were when demonstrating it to the public. We have all seen it be officially demoed, we all know it exists, but none of us are anywhere close to being able to own a pair. This is why new developments on this product are so huge. And now we have a better idea of how sound will be delivered to the user fromthe glasses
Google is reportedly fitting the glasses with bone conduction technology in order to avoid having a separate ear piece. Bone conduction is essentially making the glasses vibrate, transferring the sound to your bones and ultimately, your inner ear.
For those of you familiar with bone conduction headphones and handsets, Google’s method is going to behave a little differently. In devices using bone conduction technology that we’ve seen previously, there is a vibration transducer that vibrates directly on your bones, injecting the sound. However, Google is reportedly using the actual glasses as the vibration transducer. This is possible because the glasses will be in contact with your bones at all times anyway.
As it stands, there is possibility of potential customization when it comes to where the user actually wants the sound delivered. Google has mapped out four possible locations for sound delivery: near the eyebrow, behind the ear, above the nose, or near the temple. We aren’t exactly sure if the location of sound delivery will change according to body type, personal preference, or a simple choice by Google.
These details, available in a patent Google filed back in October 2011, were just made public and really shows Google’s commitment to this technology.
