Personalization for Accessibility

I'm looking for web apps or online experiences that offer personalization options to users with the intent to improve accessibility, such as increased font-size, variable color scheme or layout (for example, always give me mobile). Thoughtful implementations would persist after users leave the site, so their desired settings would still be there when they came back.

Trello has an "Enable Color Blind Friendly Mode". It's pretty simplistic and probably not that useful, but their hearts are in the right place.

Have you seen any applications that do well with this type of offering?

Accessibility Support in HTML5 Audio

Here are a few things I found in testing HTML5 Audio in various browsers and screen readers:

  • The controls do work in Safari and Voiceover, they just require more key commands than "space". You have to press Control + Option + Space to toggle playback.
  • I had trouble toggling playback in Safari and Chrome with just the keyboard.
  • Mobile Safari and Voiceover worked fine.
  • Firefox and Edge both work from the keyboard alone
  • Firefox and JAWS required two taps of the space key.
  • Edge and JAWS did not work at all–probably because of immature accessibility support in the new browser.
  • Labeling the audio element with an aria-label attribute would help to give the track a title. It won't work in every browser due to accessible name calculation specs, but it's better than none.
