Project Glass is a research and development program by Google to develop an augmented reality Head-Mounted Display (HMD). The intended purpose of Project Glass products would be the hands-free displaying of information currently available to most smartphone users, and allowing for interaction with the Internet via natural language voice commands. These glasses will have the combined features of virtual reality and augmented reality. Google glasses are basically wearable computers that will use the same Android software that powers Android smartphones and tablets.

Google Glass is as futuristic a gadget we’ve seen in recent times. A useful technology for all kinds of people including handicapped/disabled.

It is part of the Google X Lab, which works on other futuristic technologies. The intended purpose of Project Glass products would be the hands-free displaying of information currently available to most smartphone users, and allowing for interaction with the Internet via natural language voice commands. The functionality and physical appearance (minimalist design of the aluminum strip with 2 nose pads) has been compared to Steve Mann's EyeTap, which was also referred to as "Glass" ("EyeTap Digital Eye Glass", i.e. uses of the word "Glass" in singular rather than plural form "Glasses"). The operating system software used in the glass will be Google's Android.

As per many reports, Google is expected to start selling eyeglasses that will project information, entertainment and, this being a Google product, advertisements onto the lenses. These glasses will have the combined features of virtual reality and augmented reality.

The Google Glasses can use a 4G cell connection to pull in information from Google’s mountain of data and display info about the real world in augmented reality on the lens in front of your eye. As you turn your head you’ll get information about your surroundings and nearby objects from Google Goggles, info on buildings and establishments from Google Maps, even your friends’ nearby check-ins from Latitude. The company has no plans to sell ads into your newly augmented view of the world, but will consider it if the product really catches on.

The device will probably communicate with mobile phones through Wi-Fi and display contents on the video screen as well as respond to the voice commands of the user.

Google put together a short video demonstrating the features and apps of Google glasses. It mainly concentrates on the social networking, navigation and communication.

The video camera senses the environment and recognizes the objects and people around. The whole working of the Google glasses depends upon the user voice commands itself.
