Introduction:
Computer has become a part and parcel of our lives. To start with there was no need to point because computers used crude interfaces like teletype machines or punch cards for data entry. The early text terminals did nothing more than emulate a teletype (using the screen to replace paper), so it was many years (well into the 1960s and early 1970s) before arrow keys were found on most terminals. Full screen editors were the first things to take real advantage of the cursor keys, and they offered humans the first crude way to point. Light pens were used on a variety of machines as a pointing device for many years, and graphics tablets, joy sticks and various other devices were also popular in the 1970s. None of these really took off as the pointing device of choice, however. Need of a simple to use and accurate pointing device lead to the invention of computer mouse (called so because of its resemblance to mouse with its tail).Beginning its life with wheels, mouse was an immediate success. But it was soon realized that the wheel mouse required a lot of maintenance and required a smooth surface for proper operation .Advent of technologies like optical navigation revolutionized the mouse and soon a better version of old wheel mouse "The Optical Mouse" was born.
