TalkBack vs VoiceOver

TalkBack Menu

The TalkBack menu provides navigation shortcuts similar to the VoiceOver Rotor:

• Headings
• Links
• Landmarks
• Form controls
• Buttons
• Controls

Open the TalkBack menu by swiping up then right in a single motion (or using the Accessibility button).

Testing With TalkBack

// TalkBack testing checklist
const talkbackChecklist = [
  'Page loads correctly',
  'Content reads in correct order',
  'Touch targets are 48dp minimum',
  'Form fields announce labels',
  'Focus indicators visible',
  'Custom gestures do not conflict',
  'Dynamic content announces',
];

Common Mistakes

• Not testing with TalkBack on real Android devices: Emulators do not perfectly simulate touch gestures.
• Using small touch targets: Minimum 48x48dp for accessibility on Android.
• Assuming TalkBack works like VoiceOver: Gesture patterns differ.
• Not testing with Explore by Touch: This is the default interaction mode for most TalkBack users.

2. How do you activate a focused item in TalkBack? Double-tap anywhere on the screen.
