Detailed explanation-1: -An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.
Detailed explanation-2: -A mouse that uses light to detect movement. Introduced in the late 1990s, optical mice superseded mechanical mice because their sealed bottom surfaces do not absorb dust and dirt. They work by emitting light from an LED or laser, and a CMOS sensor detects the light reflections as the mouse is moved.
Detailed explanation-3: -Users can also employ mice gesturally, meaning that a stylized motion of the mouse cursor itself, called a “gesture", can issue a command or map to a specific action.
