A little more than 50 years ago Douglas Engelbart introduced his "X–Y position indicator for a display system"—more commonly known today as the computer mouse—during a 90-minute presentation on a "computer-based, interactive, multiconsole display system" at the Stanford Research Institute (SRI) in Menlo Park, Calif.
In the patent application it is described as an "X-Y position indicator for a display system". Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. His group also called the on-screen cursor a "bug", but this term was not widely adopted.
