Accessibility in SpeakerClock 1.3.1 | Cocoanetics


Now you can absolutely function SpeakerClock with no or low imaginative and prescient. We gave SpeakerClock the total Accessibility remedy. On this article I describe a number of the issues I discovered including accessibility options to SpeakerClock, now that it’s absolutely written in SwiftUI.

SpeakerClock’s UI is split into 3 sections, the presets on the high, the LED timer as large as potential within the heart and the part “visitors mild” on the backside.

The principle interplay gesture is to horizontally swipe over the LED digits to alter the timer. This sort of gesture will not be potential when VoiceOver is lively as a result of there you possibly can pan over the display screen to shortly get to the new spots of interactive parts.

I solved this by having individually adjustable sub-elements for the minutes and seconds whereas the timer will not be operating. This fashion you possibly can swipe vertically to regulate the minutes and seconds individually.

There are three varieties of ordinary gestures for Voice-Over which I made full use of:

  1. double-tap with single finger to pick out a component
  2. double-tap with two fingers to carry out a “magic faucet”
  3. draw a Z with two fingers to “escape”

I used #1 for the single-tap perform of the preset and talking part buttons. #2 substitutes for the lengthy press. The rationale is that you must consciously faucet with two fingers as an alternative of 1 to switch the presets, as to forestall you from by chance altering them.

Within the common move of issues, VoiceOver principally feedback on the targeted factor and after a brief pause additionally reads out the accessibility trace that tells the consumer what interactions are potential. I additionally used VoiceOver’s announcement notifications to present audio suggestions on some interactions.

The cherry on high is that sure timer values get pink out aloud. Within the yellow and inexperienced phases you get a voice immediate each minute. The part transitions get introduced as nicely. Within the pink part there’s an announcement very 15 seconds, with the ultimate 10 seconds being accompanied by beeps.

That felt like an inexpensive quantity of voice suggestions for starters. I would add some configuration choices at a later level.

On this video I’m demonstrating all that we mentioned.

Conclusion

I might say my implementation is 95% good. There are some edge instances nonetheless – which I can’t do a lot about – the place VoiceOver will insist of talking one thing that it wouldn’t must. Sadly there is no such thing as a strategy to inform Accessibility to “shut it” for sure occasions when there’s something extra vital happening.

It price me quite a lot of experimenting and the higher a part of a day to get to this stage. I’m anxious to listen to from precise customers of SpeakerClock, specifically those that are visually impaired and may need use for a timer. And a few common customers additionally requested about acoustic suggestions. What kind of configuration choices associated to sounds may make sense?
