Siri
With Siri, you can do things with your iPhone just by asking, and VoiceOver can read Siri responses
to you. For information, see Chapter 4, “Siri,” on page 39.
Triple-click Home
Triple-click Home provides an easy way to turn some of the Accessibility features on or off when
you press the Home button quickly three times. You can set Triple-click Home to:
Turn VoiceOver on or off Â
Turn White on Black on or off Â
Turn Zoom on or off Â
Turn AssistiveTouch on or off Â
You can also set Triple-click Home to present the option to turn VoiceOver, White on Black, or
Zoom on or off. Triple-click Home is turned off by default.
Set the Triple-click Home function: Go to Settings > General > Accessibility > Triple-click Home.
Zoom
Many iPhone apps let you zoom in or out on specific elements. For example, you can double-tap
or use the pinch gesture to expand webpage columns in Safari.
Zoom is also a special accessibility feature that lets you magnify the entire screen of any app
you’re using, to help you see what’s on the display.
While using Zoom with an Apple Wireless Keyboard (see “Using an Apple Wireless Keyboard” on
page 27), the screen image follows the insertion point, keeping it in the center of the display.
Turn Zoom on or off: Go to Settings > General > Accessibility > Zoom. Or, use Triple-click Home.
See “Triple-click Home” on page 153.
Note: You can’t use VoiceOver and Zoom at the same time.
Zoom in or out Double-tap the screen with three fingers. By default, the screen is magnified
200 percent. If you manually change the magnification (by using the tap-
and-drag gesture, described below), iPhone automatically returns to that
magnification when you zoom in by double-tapping with three fingers.
Increase magnification With three fingers, tap and drag toward the top of the screen (to
increase magnification) or toward the bottom of the screen (to decrease
magnification). The tap-and-drag gesture is similar to a double-tap, except
you don’t lift your fingers on the second tap—instead, drag your fingers on
the screen. Once you start dragging, you can drag with a single finger.
Move around the screen When zoomed in, drag or flick the screen with three fingers. Once you start
dragging, you can drag with a single finger so that you can see more of
the screen. Hold a single finger near the edge of the display to pan to that
side of the screen image. Move your finger closer to the edge to pan more
quickly. When you open a new screen, Zoom always goes to the top-middle
of the screen.
Large Text
Large Text lets you make the text larger in alerts, and in Calendar, Contacts, Mail, Messages,
and Notes.
Set the text size: Go to Settings > General > Accessibility > Large Text.
