The Computer Mouse

By Connor Welsh


The purpose of the mouse is to be able to easily navigate the computer or computer applications. The mouse is very simple with three different buttons/utilities but it has four different functions. The first is a touch sensor on the bottom of the mouse, which allows you to move the on-screen cursor with little effort. The next is probably the most used button, the left click. This is used to execute a function, such as opening an application. The second button is the right click, this is used to change how to execute something, such as opening an application as an administrator. The last is the scroll wheel. This is placed in-between the left and right click buttons, and it rotates vertically. Scrolling down moves the page down, and moving it up moves the page up.


Dr. Douglas C. Engelbart had the idea of the computer mouse and patented it. He owns his original mouse idea, (x and y wheels). Engelbart hired Bill English as his cheif engineer, and thus the mouse was born. Engelbart had the idea in 1961, but Bill English and his team made it a reality in 1964.


When this was first invented, it moved with x and y axis wheels, now it moves with touch sensors. As far as purpose goes, they are both basically meant to do the same thing.


In 1987, Logitech made a change to their mouses which enabled it to detect velocity changes.

In 1989, Logitech began to manufacture their mouses to where it would comfortably fit the palm of a hand.

In 1999, Agilent developed an optical mouse sensor, which was later used by Microsoft for their mouses.

In 2004, Logitech made another improvement on the motion of the mouse. They began advertising that their mouses now had laser tracking technology, which fixed the problems that LED mouses had.

Technology Classification

The computer mouse falls under the category of Information and Communication. The mouse exchanges information with the computer and computer screen, to create a functional cursor display on the screen.



The mouse has made the use of the computer much more simple and easy. Those who hadn't bothered to learn how to navigate a computer before simply didn't have to anymore. The mouse was self-explanatory, with three buttons, it made the use of a computer significantly easier.


While the result of the mouse was exactly what the developers intended it to be, it had some social downsides. Those who were outside for a large portion of their days began to stay inside more often with the unlimited freedom of the computer and the ease of using it. Those who were socially active began to spend more time inside.

Science, Technology, Engineering, Math

The Computer Mouse

Science: Idea of x and y axis wheels to move a cursor/pointer on a computer screen.

Technology: Creating an easier way to navigate the computer.

Engineering: Design something hand-held and simple. Needs to be able to move on a desk.

Math: What is the best way to traverse the desk while sliding.

What I would change

Normally, wired mouses have a plug that cannot be removed from the mouse itself. I would have a USB port in the front of the mouse so you only need one cord for all of your wired mouses. This would save you the tedious process of untangling the heaps of wires.
