Google Glass – How does it work and what are its functions?

Google glass is a device launched by Google first on April 15, 2013 which is based on optical head-mounted display technology. In this technology there is a wearable device that is capable to reflect projected images and one can see right through it. We also call that augmented reality. Google glass appears like a pair of eyeglasses and so a person may wear it like regular prescription glasses. It was basically developed with the aim to freely access the data without actually needing the handheld devices like smartphones. Whichever image or video displayed or audio heard can only be observed by the owner of the device and not others around him or her.
