MOUSE, TRACKBALL & TOUCHPAD Gaia Bernarello e Francesca Raimondi

The mouse is an important tool for communicating with computers. Commonly known as a pointing device, it lets you point to objects on the screen, click on them, and move them.

There are two main mouse types: optical and mechanical.

The optical mouse uses an electronic eye to detect movement and is easier to clean.

The mechanical mouse uses a rolling ball to detect movement and requires regular cleaning to work.

There are other devices that can do the same thing as a mouse. Many people find them easier to use, and they also require less desk space than a traditional mouse. The most common mouse alternatives are below.

Trackball: A trackball has a ball that can rotate freely. Instead of moving the device like a mouse, you can roll the ball with your thumb to move the pointer.

Touchpad: A touchpad — also called a trackpad — is a touch-sensitive pad that lets you control the pointer by making a drawing motion with your finger. Touchpads are common on laptop computers.
