We had all imagined what the future would be like in our childhood, picturing pretty intense technology like flying cars, houses floating in the air, holographic telephones, etc. But we look at the world now and see those ideas actually come to life. One of such devices is Google’s latest project, “Google Glass”. What is Google Glass? What does it promise to do? What are its salient features? We will find out all this and more as we go further.In simple terms, google glass is a computer which you can wear on your head the same way as in you would wear a set of spectacles, which comes with an Optical Head Mounted Display (OHMD) working on a class of technology called “Augmented Reality”.  

A machine consists of many sub systems working together to perform a certain task. The information from the electronic devices are retrieved from the machine sub systems as binary code. All this information is presented in a user readable formatthrough a display device. The display technology has seen a rapid growth in the past few decades from the old CRT (Cathode Ray Tube) displays to the presently in demand LCD (Liquid Crystal Display) and LED (Light Emitting Diode) displays. The LCDs and LEDs consists of two dimensional arrays of individual display units (pixels) whose number to size of display determines the clarity of the display (resolution).
