<br />
A '''computer mouse''' is a [[pointing device]] that detects two-dimensional motion relative to a surface. This motion is typically translated into the movement of a pointer on a [[graphical user interface]] (GUI), allowing for the control and interaction with the computer's [[user interface]].<br />
<br />
== History ==<br />
The first computer mouse was invented by [[Douglas Engelbart]] in 1964 at the [[Stanford Research Institute]]. Engelbart's mouse was a simple device with two perpendicular wheels that could track movement in two dimensions. The term "mouse" was coined because the device resembled the shape and size of a real mouse, with the cord resembling a tail.<br />
<br />
== Types of Computer Mice ==<br />
There are several types of computer mice, each with different technologies and functionalities:<br />
<br />
* '''Mechanical Mouse''': Uses a rubber or metal ball that rolls on a surface to detect movement. The ball's motion is translated into cursor movement on the screen.<br />
* '''Optical Mouse''': Uses an [[LED]] light and a sensor to detect movement. The light bounces off the surface and is captured by the sensor to determine the direction and speed of movement.<br />
* '''Laser Mouse''': Similar to an optical mouse but uses a laser for more precise tracking.<br />
* '''Wireless Mouse''': Connects to the computer via [[radio frequency]] (RF) or [[Bluetooth]] technology, eliminating the need for a physical cord.<br />
* '''Trackball Mouse''': Features a ball on top of the device that the user rotates to move the cursor, rather than moving the entire mouse.<br />
<br />
== Components ==<br />
A typical computer mouse consists of several key components:<br />
<br />
* '''Buttons''': Most mice have at least two buttons (left and right) for clicking and selecting items. Some mice also include additional buttons for extra functionality.<br />
* '''Scroll Wheel''': Located between the buttons, the scroll wheel allows for easy navigation through documents and web pages.<br />
* '''Sensor''': Detects the movement of the mouse and translates it into cursor movement on the screen.<br />
* '''Microcontroller''': Processes the signals from the sensor and buttons and sends the appropriate data to the computer.<br />
<br />
== Usage ==<br />
The computer mouse is an essential input device for many types of software, including [[operating systems]], [[web browsers]], and [[productivity software]]. It allows users to interact with graphical elements on the screen, such as icons, buttons, and menus.<br />
<br />
== Ergonomics ==<br />
Ergonomics is an important consideration in the design of computer mice. Poorly designed mice can lead to [[repetitive strain injuries]] (RSIs) such as [[carpal tunnel syndrome]]. Ergonomic mice are designed to fit the natural shape of the hand and reduce strain during use.<br />
