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? A computer mouse is used to move or manipulate objects on a computer screen. When a person is using a mouse, they will see a pointer (cursor) on the computer …show more content…

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.

Micro switch that signals to the mouse when you press on the right button. There is an identical one on the other side for the left button. 6. USB cable (Woodford, 2016) Woodford, Chris .

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. Invest in a product that will hold up and last a long

It is a rectangle that has a screen in the middle and two dials, one on each side of the screen. The dials move a stylus that draw lines on the screen. It is a very simple toy that works a hundred percent on its own, it does not require batteries and does not have any hazardous pieces.

Describe the design on the machine and how their component parts work to produce an image.
The Central Processing Unit is the brains of the operation. The CPU uses the data stored in RAM to perform the needed calculations and data manipulation to perform what is needed for the user. You can tell the CPU what to do with peripheral devices like a keyboard and mouse, and the CPU then presents the data to you in the form of sound, or images on a monitor. Touchscreens perform both the input and output role by allowing you to see what is displayed while using the screen as a mouse and keyboard. There are several methods for tracking your inputs, but they all do the same thing, tell the computer where on the screen you are pointing.

Once the device is turned on, the wheel with tongues spins vertically on its axis. The body of the case contains buttons which allow switching among the speeds and their direction. A total of three speeds along with one rapid flickering multidirectional motion are offered to ladies who want to experience every pleasure offered by oral stimulation.
I use the keyboard to be able to type it, the mouse to be able to point on the screen and click or access my data by using the mouse arrow. USB to be able to save my data, edit it later and allow me to organise my files for example to create folders and sub-folders for my files.
The computer obsession began when the first computer was built in 1939. There are many uses of a computer like the proper way and the negative way. The way Annalee Newitz uses her computer is good and bad. The definition of a good teaching tool is the best way to teach a class or something that is taught. Using a good teaching tool is not always easy. There are many things about computers who make people depend or use too much to stop depending on technology.

The most common type of computer is the personal computer, which is otherwise known as P.C., or the desktop computer. Computers contain countless electronic parts. These parts all contribute to processing, sorting, and receiving data. Usually, computers are linked to thousands of other computers and handheld devices via the World Wide Web or also known as the internet. It is estimated that about half of the jobs today use computers. Computers have changed the way we communicate and learn forever. You can communicate to other people using phones, laptops, tablets and PCs. You can do all of this through the internet or also known as the World Wide Web. Before modern communication we didn't know about things happening on the other side of the world for weeks or even months. But today we know what is happening all over the world in an
