Who invented the computer mouse and when?

The computer mouse was invented by Douglas Engelbart in 1964. Engelbart, an American engineer, created the mouse as part of his vision for improving human-computer interaction. The original mouse design consisted of a wooden box with two wheels that could move a cursor on a screen. Engelbart’s invention was first demonstrated publicly in 1968 at the “Mother of All Demos,” which also showcased other interactive technologies like hypertext and video conferencing. The mouse became a standard input device in personal computers and revolutionized how people interact with digital systems.
