Optical mouse: Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse's movement.
The mickey, in a computing context, is a unit for the smallest detectable movement of a mouse. The mickey is not precisely quantified but varies depending on the specific equipment. A typical mickey would be about 0.1 millimeters (about 0.0039 inches).
The computer mouse is typically measured by its sensitivity, which is expressed in dots per inch (DPI). A higher DPI indicates greater sensitivity, allowing for more precise movement on-screen. Additionally, the size and weight of the mouse can also be relevant measurements, depending on user preferences and ergonomics.

They get dirty, they are not as accurate as an optical mouse, and like anything with a moving part they will wear out.
The movement of a mouse refers to the physical action of the device as it is moved across a surface, which translates into cursor movement on a computer screen. This is achieved through various technologies, such as optical sensors or ball-based mechanisms, that detect the motion and direction of the mouse. The movement can be used for a range of tasks, including navigation, selection, and interaction with software applications. Overall, mouse movement is a crucial aspect of user interface navigation in computing.
