In most browsers, hover over the video to display the controls if they’re not already visible.(You can try it yourself. Turn on your device’s screen reader in the Accessibility section. For iPhones, go to Settings > General > Accessibility > VoiceOver. For Android, go to Settings > Accessibility. Give it a try for a few hours. Good luck. It takes a while to get the hang of it, but it will come.)
Browsing on touchscreen devices involves a range of gestures, many of which offer far more functionality than the tap and swipe gestures of the sighted world. To give you a better idea, here is a sample of some of the most common gestures for VoiceOver:
Drag one finger over the screen to explore the interface and hear the screen reader speak what’s under your finger.
Flick two fingers down the screen to hear it read the page from the top down.
Single tap brings a button or link in focus (so you know what it is); double tap activates the control.
3-finger horizontal flick is the equivalent of a regular swipe.
3-finger vertical flick scrolls the screen up or down.
As you can see, the vocabulary of gestures that users with low vision have to learn is quite wide. We know that gestures have low discoverability and learnability, yet for power users they do represent the only way to navigate efficiently through a system largely based on sequential access.
