Learn the basics of how to use VoiceOver and a set of procedures for iOS accessibility testing. Bring an iOS device if you have one and follow along - this will be a hands-on session. We'll start by turning on VoiceOver, and adjusting some settings. Then we will practice some simple gestures. With this foundation in place, we'll go through (and also practice) a set of VoiceOver test procedures for native apps and mobile web content.

39. • Test with the native iOS keyboard, not 3rd party
• Input is slow & difficult with onscreen keyboard
Entering data

40. • In the beginning it’s OK to cheat:
look, touch and tap
• Don’t rely on seeing screen –
however screen curtain not essential
• OK to turn off and on VO
(triple click home)
• Double tap anywhere on screen
• Screen may not scroll automatically
• Three finger swipe will scroll screen
• Simple gestures are enough
No need to test all gestures
Keep in mind

41. Basic test procedures
1. Listen to the screen
without interacting
2. Move through the screen
using swipe
3. Interact with elements
What is this thing and what
does it do?
Can you complete action?
Meaningful order & sequence
Can you complete task?

42. Practice with the Camera App
1. Turn VO off
2. Open Camera
3. Turn VO on
