After last week's announcement of Google Glass being up for grabs-and at a price of under $1,500-for 8,000 creative individuals who want to be the first to own a pair, Google Glass is rolling out some new updates that may excite those who want to know more about the new device.

Binocular versions of the Google Glass

The original prototype of the Google Glass has been slated to have only one display on the right side (from the point of view of the wearer).

However, Forbes reports that Google has just filed a patent for binocular Head Mounted Displays. Instead of an improvement, this may be seen as a challenge for the company, since there are more concerns to be dealt with.

Issues such as the sizes for comfort for future users and the immersion into augmented reality and its potential consequences to the user are just some of these.

At the same time, it also begs the possibility of a game-changing device-imagine when the Google Glass finally becomes a staple on everyone's routine. Plus, Google Glass even has the potential to switch the device to corrective glasses, making it a headgear that is capable of more than just wearable technology device.

Tether for 3G and 4G

According to Forbes, it has already been confirmed that the Google Glass will be used to connect via Bluetooth for Android smartphones as well as the iPhone. In essence, it can extract data using 3G or 4G from another phone, thus a necessary tether to an accompanying device.

What's even better news is that Google Glass will also be available for iOS device users, as the main goal of the device is to have as many points of information available to the user.

Forbes also brings up a good issue of ethics and etiquette when it comes to using the Google Glass. Considering one of its main features-taking photos without having to press or hold anything up like in the traditional sense-Google Glass will now allow for instant photos at a clear command.

This means that you have a hands-free approach to taking photos, an ease and convenience factor that is attractive for those on the go. However, it also calls into question how it can be a form of negative response from the photo subject.

Imagine being paranoid of people taking photos of you, assuming that Google Glass will become a staple device-wear in the future. It's not easy to tell whether or not someone is taking a photo of someone else, and it can come down to the issue of ethics and rights.

Stealth hearing aids

Of course, the definition of stealth here comes into question, considering how half your face will be covered by the device that aids your hearing. With that said, BBC reports a potential function of the Google Glass, and touches on the interesting bit of audio functions without the use of an earpiece.

Considering how earpieces can affect the way a user may perceive surrounding sounds, it is a good refinement on how one can hear the data coming from the device without blocking out everyday sounds from the outside.

According to BBC, this is done with the use of vibrations, sending the sound to the ear through the skull. This type of sound sending, as well as potential amplification of the sound can even aid those with a lower level capacity in terms of hearing, reports Forbes.
