Mouse mechanism cutaway

A mouse is a handheld pointing device for computers, involving a small object shaped to sit naturally under the hand, that can detect its motion relative to a flat surface and usually fitted with one or more buttons. The 2D motion of the mouse is typically translated into the motion of a cursor on the display. The mouse was invented by Douglas Engelbart of Stanford Research Institute in 1963 after extensive usability testing. It was one of several experimental pointing devices developed for Engelbart's oN-Line System.
