Just gazing at a blank wall can remind you that you have to meet your girlfriend in the evening, claims Google after unveiling technological specifications of its new augmented reality glasses.

In a concept video posted on Google+, Google developers explained how their groundbreaking technological innovation can change the way people perceive or remember reality at a given moment.

The video shows that a man wearing the augmented reality glasses is being alerted to potentially bad weather when he glances outside the window. Different reminder services such as to-do tasks and current location information will also be available to users when they put the eyewear on.

With a total of 14 services on offer, the Project Glass “helps you explore and share your world, putting you back in the moment”, developers working with the company’s experimental lab Google X said in a statement.

Along with the video, Google also posted a few images of the new gadget, revealing details of the product’s design and maneuverability. As one might expect from Google, the device comes with a minimalistic look with a microphone and a semi-transparent video screen that allows the user to obtain moving imageries on the go.

The spectacles are also equipped with an audio output device to let users play their favourite music or any type of audio file, the images demonstrated.

Not disclosing when the new device would hit the shelves or how much it would cost, Google X developers said the reason for sharing technical specs now is to receive feedback from the potential customers.

However, the augmented reality systems may be commercially available on the market by the end of 2012, predicts The NY Times.
