Google Glass (styled “GLΛSS”) is a wearable computer with a head-mounted display (HMD) that is being developed by Google in the Project Glass research and development project, with the mission of producing a mass-market ubiquitous computer. The computer in the glass is running an Android OS (Android 4.0.4)Google Glass displays information in a web card format just like Google Now Cards , that can interact with the Internet via natural language voice commands, which are more advance than the current Voice to Text feature.Glass is being developed by Google x, which has worked on other futuristic technologies such as driverless cars. The project was announced on Google+ by Project Glass lead Babak Parviz, an electrical engineer who has also worked on putting displays into contact lenses; Steve Lee, a product manager and “geolocation specialist”; and Sebastian Thrun, who developed Udacity as well as worked on the self-driving car project.
Thad Starner, an augmented reality expert, is a technical lead/manager on the project.

The glass is mainly used to display information to the user. And not intended to handle heavy jobs like gaming. Because battery and the safety of the eye is most important aspect to care about.

This kind of  a view will be displayed on the right hand top corner of the glass. This view is captured when the video record mode is active.
