This video shows What is Trackball and How to works Trackball. And also it is a very old devices.

A computer trackball is a pointing device that provides an alternative to traditional mice for interacting with a computer. Unlike a mouse, which is moved across a surface to control the cursor on the screen, a trackball remains stationary while the user manipulates a ball with their fingers or thumb.

The trackball typically consists of a ball housed in a socket, with sensors or rollers that detect the ball's movement. Users can rotate or spin the ball to control the on-screen cursor, and some trackballs also feature additional buttons for clicking and other functions. The stationary nature of the trackball offers ergonomic advantages, as users don't need to move the entire device across a surface, making it suitable for a variety of environments where space may be limited.

Trackballs are commonly used in applications where precision is crucial, such as graphic design, CAD (computer-aided design), and gaming. They are also popular in industrial settings, where the need for a compact and durable pointing device is essential. Additionally, trackballs are sometimes preferred by individuals with mobility issues who find traditional mice challenging to use.

Overall, the design of a computer trackball provides a unique and versatile input method, offering users a different approach to navigating and interacting with their computers.
