Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer, inventor, and a pioneer in many aspects of computer science.He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, [a] and the development of ...
A computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface
Richard "Dick" Francis Lyon (born 1952) is an American inventor, scientist, and engineer. He is one of the two people who independently invented the first optical mouse devices in 1980. [1] [2] [3] He has worked in signal processing and was a co-founder of Foveon, Inc., a digital camera and image sensor company.
The first prototype of a computer mouse, as designed by Bill English from Engelbart's sketches [1]. Early dynamic information devices such as radar displays, where input devices were used for direct control of computer-created data, set the basis for later improvements of graphical interfaces. [2]
While working at PARC, English developed a ball mouse, in which a ball replaced the original set of wheels. [2] It worked similarly to a moveable ball-based mouse device called Rollkugel, which had been developed by Telefunken, Germany, and was offered since 1968 as input device for their computers.

In computing, a pointer or mouse pointer (as part of a personal computer WIMP style of interaction) [10] [11] [12] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place.
A computer mouse Touchpad and a pointing stick on an IBM notebook Trackpoint An elder 3D mouse 3D pointing device. A pointing device is a human interface device that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer.
With its mouse-driven GUI, the Alto would go on to influence Steve Jobs and Apple's Macintosh computer and operating system in the 1980s. [23] Eventually, Microsoft 's Windows operating system would follow the Macintosh and use a multi-button mouse in the same way that the Alto and the NLS system did.
