Mouse and Other Pointing Devices
A variety of options are available for typing on a smart phone (Figure 8). Many can display
an on-screen keyboard, where you press the on-screen keys using your finger or a stylus.
A stylus is a small metal or plastic device that looks like a tiny ink pen but uses pressure
instead of ink. 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.

Mouse and Other Pointing Devices
A mouse is a pointing device that fits comfortably under the palm of your hand (Figure 9).
With a mouse, users control the movement of the pointer , which is a small symbol on the screen
whose location and shape change as a user moves a pointing device. As you move a mouse, for
example, the pointer on the screen also moves. Generally, you use the mouse to move the pointer
on the screen to an object such as a button, a menu, an icon, a link, or text. Then, you press a
mouse button to perform a certain action associated with that object. The bottom of a mouse
is flat and contains a mechanism (ball, optical sensor, or laser sensor) that detects movement of
the mouse.
