(History Computer) The first computer mouse was conceived of in the early 1960’s by Douglas Engelbart, then a Director of Augmentation Research Center (ARC) at Stanford Research Institute (SRI), in Menlo Park, California.

At the time of the invention of the mouse, Engelbart had already been exploring possible ways for people to increase their capability to solve complex problems for almost a dozen years.

Engelbart decided to find an easy way for humans to interact with machines.

The mouse was just a tiny piece of a much larger project, started in 1962, aimed at augmenting human intellect. [1]

(History Computer) Engelbart and William (Bill) English (a colleague of Engelbart and the maker of the mouse) envisioned problem-solvers using computer-aided working stations to augment their efforts. They required the ability to interact with information displays using some sort of device to move a cursor around the screen.

There were several devices then in use, or being considered for use: the light pen, joysticks, trackballs, trackpads, tablets with styli etc.

There was even one that users were supposed to control with their knees. [2]

(History Computer) However, Engelbart was looking for the best and the most efficient device.

They approached NASA in 1966 and said “let’s test them” and determine which of the devices works well.

The project was funded by NASA and the team developed set of simple tasks and timed a group of volunteers in performing those tasks with the various devices. I was amazed to see how Engelbart and team relied on user testing the product prototype and validated by quantifying test results.

One of the tasks for the usability test was that the computer would generate an object in a random position on the screen, and a cursor somewhere else on the screen. The team tracked the time it took the user to move the cursor to the object.

These usability tests revealed that the ‘mouse’ outperformed all other devices. For e.g. devices like the light pens seemed simplest, but they took longer time, because the user had to pick them up and put them down each time. The tests also revealed that this was a tiresome activity.

In 1964, the first prototype of computer mouse was developed to use with a graphical user interface (GUI). The original mouse had the cord in front, and the team moved it to the back end to get it out of the way. [3]

The first mouse was a simple mechanical device with two perpendicularly mounted discs on the bottom.

X-Y position indicator for a display system (Patent) Engelbart applied for a patent in 1967 and received it as an assignor of SRI for the wooden shell with two metal wheels. “It was nicknamed the mouse because the tail came out the end,� Engelbart revealed about his invention.

His version of windows and GUI was not considered patentable (no software patents were issued at that time), but Engelbart has over 45 other patents to his name. [4] Mouse Patent

(Wired Archive) In Doug’s Words: “The mouse we built for the [1968] show was an early prototype that had three buttons. We turned it around so the tail came out the top.

We started with it going the other direction, but the cord got tangled when you moved your arm.

I first started making notes for the mouse in ‘61.

At the time, the popular device for pointing on the screen was a light pen, which had come out of the radar program during the war. It was the standard way to navigate, but I didn’t think it was quite right. Two or three years later, we tested all the pointing gadgets available to see which was the best. Aside from the light pen there was the tracking ball and a slider on a pivot. I also wanted to try this mouse idea, so Bill English went off and built it.

Drawing from Engelbart’s Patent

We set up our experiments and the mouse won in every category, even though it had never been used before. It was faster, and with it people made fewer mistakes. Five or six of us were involved in these tests, but no one can remember who started calling it a mouse. I’m surprised the name stuck. We also did a lot of experiments to see how many buttons the mouse should have. We tried as many as five.

We settled on three. That’s all we could fit. Now the three-button mouse has become standard, except for the Mac.” [5]

(SRI) In early 1959, Engelbart pursued his visionary ideas by formulating a theoretical framework for the co-evolution of human skills, knowledge, and organizations. At the heart of his vision was the computer as an extension of human communication capabilities and a resource for the augmentation of human intellect.

By 1968, Engelbart created and became the director of SRI’s Augmentation Research Center. With a group of young computer scientists and electrical engineers from the center, on December 9, 1968 he staged a 90-minute public multimedia demonstration at the 1968 Fall Joint Computer Conference in San Francisco. It was the world debut of personal and interactive computing, featuring a computer mouse that controlled a networked computer system to demonstrate hypertext linking, real-time text editing, multiple windows with flexible view control, cathode display tubes, and shared-screen teleconferencing.

For its impact on computing and the world, the 1968 event has been dubbed “the mother of all demos.” [6]

(Doug Engelbart Institute) The mouse later migrated from Doug’s lab at SRI to Xerox PARC, and then to Apple and others. One of the most common myths about the mouse is the mistaken belief that it was invented at Xerox PARC. Note that the patent for the mouse was filed in 1967, by which time production models were in operational use throughout Doug’s lab, three years before Xerox PARC was established in 1970. [7]
