Computer Mouse
Computer Mouse
A computer mouse is a handheld hardware input device that controls a cursor in a GUI (graphical user interface) and can move and select text, icons, files, and folders on your computer.
For desktop computers, the mouse is placed on a flat surface (e.g., mouse pad or desk) in front of your computer. The picture is an example of a desktop computer mouse with two buttons and a wheel.
Who invented the mouse?
The mouse was originally known as the X-Y Position Indicator for a Display System and was invented by Douglas Engelbart in 1963 while working at Xerox PARC. But, due to Alto's lack of success, the first widely used application of the mouse was with the Apple Lisa computer. Today, this pointing device is on virtually every computer.
What are the uses of a mouse?
Below is a list of computer mouse functions to give you an idea of all the things a mouse is capable of doing.
Move the mouse cursor - The primary function is to move the mouse pointer on the screen.
Open or execute a program - Once you've moved the pointer to an icon, folder, or other object clicking or double clicking that object opens the document or executes the program.
Select - A mouse also allows you to select text or a file or highlight and select multiple files at once.
Drag-and-drop - Once something is selected, it can also be moved using the drag-and-drop method.
Hover - Moving the mouse cursor over objects with hover information can help discover the function of each object on the screen. For example, hover the mouse over the "hover" link to see an example.
Scroll - When working with a long document, or viewing a long web page, you may need to scroll up or down. To scroll, use the mouse wheel, or click and drag the scroll bar.
Perform other functions - Many desktop mice also have buttons that can be programmed to perform any function. For example, many mice have two side buttons on the thumb portion of the mouse the button closest to the palm can be programmed to go back on web pages.
How has the mouse increased computer usability?
By using a computer mouse, you don't have to memorize commands, such as those utilized in a text-based command line environment like MS-DOS. For example, in MS-DOS you would need to know the cd command and dir command and type the commands on the keyboard to open a directory (folder) and view its files. Whereas a Windows user only has to double-click to open a folder and see its contents.
Types of computer mice
Below is a listing of all the types of computer mice and pointing devices used with a computer. Today, for a desktop computer the most common type of mouse is an optical mouse that connects to the USB port and known as a USB mouse. For laptop computers, the most common type of mouse is the touchpad.
Cordless (Wireless)
Footmouse
IntelliMouse (Wheel mouse)
J-Mouse
Joystick
Mechanical
Optical
Touchpad (Glidepoint)
Trackball
TrackPoint
Computer mouse ports
Today, most computer mice connect to a computer using a USB port. Below is a list of ports and wireless connections a mouse is capable of using.

What are the parts of a computer mouse?
The parts of a computer mouse can vary by the type of computer mouse. Below is a general overview of the parts found on most computer mice.
Buttons
Today, almost all computer mice have at least two buttons, a left button and right button for clicking and manipulating objects and text. In the past, there have been mice with only one button. For example, many of the early Apple computer mice only had one button.
Ball, laser, or LED
A desktop mouse uses a ball and rollers if it's a mechanical mouse or
a laser or LED if it's an optical mouse. These components track the movement of the mouse on an x-axis and y-axis and move the mouse cursor on the screen.
Mouse wheel
Today's desktop computer mice also usually include a mouse wheel that allows you to scroll up and down on a page.
Tip
Instead of rolling the wheel if you push in on the wheel it can be used as a third button.
Circuit board
To transmit (input) all mouse signal information, clicks, and other information the mouse must also have a circuit board with integrated circuits.
Cable or wireless receiver
For a corded mouse, it also includes a cable with a plug that connects to the computer. Today, most corded mice connect to the USB port. If your computer has a wireless mouse, it needs a USB wireless receiver to receive the wireless signal and input it into the computer.
Other parts
If you're using a laptop, some of the above components mentioned earlier are not required. For example, a touchpad does not use a ball, laser, or LED to control movement it uses your finger on the touchpad. Other parts include a ball for trackball mice, extra buttons that may be on the thumb side of the mouse, and nubs that may be used with laptop mice.
What does a laptop use for a mouse?
Because a laptop is designed for portability almost all laptops today use a touchpad as the mouse, and some Lenovo laptops still use a TrackPoint. Also, all laptop computers can have a USB corded or wireless mouse also attached to them.
Do smartphones use a mouse?
Smartphones and tablets use a touch screen as their primary input device, and therefore your finger is the mouse on these devices. With most tablets, you also have the option to connect a computer mouse and use it on the tablet.
What hand should I use to control the mouse?
By default, a computer mouse is set up to be used with your right hand. However, if you are left-handed, it can be set up to be used with your left hand.
Note
Although any mouse can be set up to be used with your left hand, keep in mind that some mice are molded to fit a right hand and may feel uncomfortable with your left hand.
How do I change my mouse's batteries?
To change the batteries in your mouse, you slide back the cover on the bottom, switch out the old batteries, and then replace the cover.
Mouse vs. mice or mouses
When talking about one (singular), refer to a computer mouse as a "mouse." When talking about two or more (plural), refer to them as "mice" (preferred), or "mouses."
Tip
To help prevent confusion, some companies and writers avoid using either plural form of a mouse by referring to multiple mice as "mouse devices."
Is "mouse" an acronym?
No. Some believe that mouse is short for "manually-operated user-select equipment." However, when Douglas Engelbart helped invent the mouse, he called it a mouse because the device resembled the rodent.
