Touchpad  25

Touchpad

A touchpad is available on most laptops and provides the functionality

of amouse. It has a touch-sensitive surface that senses the motion

and position of your finger(s). You can use the touchpad to move the

cursor, drag or move selected items, and click by tapping the surface.

Gesture-enabled touchpads support gestures such as zoom, pinch, rotate,

scroll, andso on. You can also purchase external touchpads.

NOTE: For information on using the touchpad, see “Using Your

Touchpad”.

Display

Displays are classified based on their screen size, resolution, color gamut,

and so on. Generally, a screen with higher resolution and better color

support provides better image quality. Some external displays also have

USBports, media-card readers, and so on.

Displays may also support features such as, touchscreen, 3D,

andwirelessconnection.

Touchscreen

Touchscreen is a display device that lets you interact with the objects on

the screen by touching the display instead of using a mouse, touchpad, or a

keyboard. You can operate a touchscreen with a finger, or another passive

object, such as a stylus. Touchscreens are commonly used in phones,

tablets, computers, and so on. Commonly used touchscreen technologies

are capacitive touch and resistive touch.

NOTE: Touchscreen may not be supported on all computers.

NOTE: For information on using the touchscreen, see “Using Your

Touchscreen”.

3D-capable displays can display 3D images and videos. 3D works by

presenting separate 2D images to the left and right eye. These images are

then combined and interpreted by the brain as one image with depth.

NOTE: You may need specially designed 3D glasses to be able to view

3D images.
