How an Optical Computer Mouse Works Laura Barnard WRTG 393 April 8, 2017 What is a computer mouse? A computer mouse is something most of us use on a daily basis. It is best defined as: “A computer mouse is a small device that a computer user pushes across a desk surface in order to point to a place on a display screen and to select one or more actions to take from that position.” (n.d.) It is an input device that is used with personal or work computers. Thanks to the computer mouse, we can interact with a computer screen in a simpler way. What does a computer mouse do?

The physical appearance of a standard computer mouse is a small object that contains: two buttons (left and right) which allows a person to “click” and drag, a scroll wheel which can act as another button, a cord and plug. Some of the newer computer mice have a trackball which is there to help scroll faster or for longer documents. The optical mouse has a LED sensor underneath the mouse as pictured below.

The optical mouse is unlike the standard, original mouse. It uses a small camera to take over 1,500 pictures per second. The mouse uses an LED (light emitting diode) that pushes light off the surface and onto a CMOS sensor which stands for complementary metal-oxide semiconductor. The CMOS sends images to the DSP (digital signal processor) for analysis. The DSP knows when there is a change in pattern. The DSP notifies the computer when there is change or movement in the mouse. Once the computer is signaled by the DSP that there is movement in the mouse, it can then move the cursor. (2000, April 24) Quite often, we use technology that we as humans have no idea how it works. It is smart to educate yourself on the different types of technology that you are looking to buy. The older, wheel-based mice could collect dust and eventually wear over time.
