A device that controls the movement of the cursor or pointer on a computer and laptop display screens. Mouse contain at least one button and sometimes as many as three, which have different functions depending on what program is running. Now mouse also include a scroll wheel for scrolling through long documents. Invented by Douglas Engelbart of Stanford Research Center in 1963, mouse is one of the great breakthroughs in computer ergonomics because it frees the user to a large extent from using the keyboard. In particular, the mouse is important for GUI because you can simply point to options and objects and click a mouse button. Such applications are often called point-and-click programs. The mouse is also useful for graphics programs that allow you to draw pictures by using the mouse like a pen, pencil, or paintbrush.
