How Computer Mouse Works?

A computer mouse is a hand-held pointing device that functions by detecting two-dimensional motion relative to its surface.

Originally, some early mice were drawn as part of circuit boards and had wired dimensions before later migrating onto the hand-drawn design we use today. Some keyboards had built-in calculating devices as well as some early mice such as the IBM M4 influenced by Ivan Sutherland’s work on interactive graphics like Sketchpad which used a lightpen for similar collaborative pad drawing programs. Moore and Engelbart innovated on these advances with video displays or monitors replacing dials and joysticks or keypads and their idea was augmented reality became the graphical user interface (GUI).
