General Description A computer mouse with the most common standard features: two buttons and a scroll wheel, which can also act as a third button.
What is a Computer Mouse? I n computing , it is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display , which allows for fine control of a graphical user interface . Physically, a mouse consists of an object held in one's hand, with one or more buttons. Mice often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.
The Inventor D r. Douglas Engelbart, a professor with the Stanford Research Institute in Menlo Park, California, developed the first device that came to be known as the mouse in 1964. At that time, the arrow keys on the keyboard were the only way of moving the cursor around on a computer screen, and the keys were inefficient and awkward . Dr. Engelbart made a small, brick-like mechanism with one button on top and two wheels on the underside. The two wheels detected horizontal and vertical movement .
The First Mouse I nventor Douglas Engelbart 's computer mouse, showing the wheels that make contact with the working surface.
Douglas Engelbart Douglas Engelbart (1925-2013), a researcher of Stanford Research Institute, wanted to find a way to make using computers easier. In those days, computers were large and expensive. Using them was very hard because everything had to be typed in by hand, and there was no way to alter things if you made a mistake. After studying and designing for a long time, Engelbart succeeded in inventing an input device which he named 'XY index'. It was nicknamed the mouse because the tail came out the end," Engelbart revealed about his invention. At first, it needed two hands to use, but it was changed so that only one hand was needed to use it. This model was more like the mouse that we use today.

Bill English Bill English , the chief engineer at the ARC ( Augmentation Research Center ) , built the first prototype of a computer mouse from Engelbart's design in 1964. SRI ( Stanford Research Institute ) also developed inkjet printing (1961) and optical disc recording (1963). Liquid crystal display (LCD) technology was developed at RCA Laboratories in the 1960s .
