How does a mechanical mouse work? When you move the mouse, the ball rolls beneath it, pushing the two plastic wheels/rollers linked to it in the process. One of those wheels detects side-to-side movement (x-axis wheel) and the other (y-axis wheel) detects movement in the up-and-down direction.

What is mouse and how it works?
A computer mouse is a handheld hardware input device that controls a cursor in a GUI and can move and select text, icons, files, and folders.The primary function is to move the mouse pointer on the screen. The mouse pointer can be used for many actions on the computer.
How does a mouse work as an input device?
A mouse is an input device that allows you to control the coordinates and movement of the onscreen cursor/pointer by simply moving the mouse across a flat surface with your hand.Most mice are now optical which means they use a laser to detect and track movement across the surface.
How does a standard mouse work?
So how does a computer mouse work? A mechanical mouse works using a wheel that is rotated. When you are moving the mouse, you move the wheel, and this rotates the whole mouse. The sensitive part of a mouse is the button itself, which allows you to click with a finger on the screen, or a stylus.
How does a modern mouse work?
Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complementary metal-oxide semiconductor (CMOS) sensor.The computer moves the cursor on the screen based on the coordinates received from the mouse.
What are the five mouse actions?

What is DPI in mouse?
DPI is the standard used to measure the mouse sensitivity, expressed as the number of DPIs (dots per linear inch) that a device can detect.The greater the number of DPIs, the higher the mouse sensitivity, and the faster the pointer speed.
How does a mouse track?
A CMOS sensor detects light.When you move your mouse, the CMOS sensor records the surface that you’re moving the mouse on. By tracking the movement of the surface, it can tell which way you’re moving the mouse. Most surfaces on which you use your mouse are not perfectly smooth.
Who invented mouse?
Development of the mouse began in the early 1960s by SRI’s Douglas Engelbart, while he was exploring the interactions between humans and computers. Bill English, then the chief engineer at SRI, built the first computer mouse prototype in 1964.
