A variety of options are available for typing on a smart phone. Many can display an on-screen keyboard, where you press the on-screen keys using a stylus or your finger. Some smart phones have one key for each letter of the alphabet, often called a mini-keyboard.

Other phones have keypads that contain fewer keys than there are letters in the alphabet. For these phones, each key on the keypad represents multiple characters, which are identified on the key.

A mouse is a pointing device that fits comfortably under the palm of your hand.

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. Some use optical sensors, and others use a laser. The latter, often referred to as a laser mouse, usually is more expensive than the former.

A trackball is a stationary pointing device with a ball on its top or side.

To move the pointer using a trackball, you rotate the ball with your thumb, fingers, or the palm of your hand. In addition to the ball, a trackball usually has one or more buttons that work just like mouse buttons.

A touchpad is a small, flat, rectangular pointing device that is sensitive to pressure and motion.

To move the pointer using a touchpad, slide your fingertip across the surface of the pad. Some touchpads have one or more buttons around the edge of the pad that work like mouse buttons. On most touchpads, you also can tap the pad’s surface to imitate mouse operations such as clicking. Touchpads are found most often on notebook computers, including netbooks and many Tablet PCs.

A pointing stick is a pressure-sensitive pointing device shaped like a pencil eraser that is positioned between keys on a keyboard.

To move the pointer using a pointing stick, you push the pointing stick with a finger. The pointer on the screen moves in the direction you push the pointing stick. By pressing buttons below the keyboard, users can click and perform other mouse-type operations with a pointing stick.
