Now you can absolutely function SpeakerClock with no or low imaginative and prescient. We gave SpeakerClock the complete Accessibility therapy. 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 prime, the LED timer as huge as potential within the heart and the part “site visitors mild” on the backside.

The primary interplay gesture is to horizontally swipe over the LED digits to vary the timer. This type of gesture is just not potential when VoiceOver is energetic as a result of there you may pan over the display 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 is just not working. This manner you may swipe vertically to regulate the minutes and seconds individually.

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

  1. double-tap with single finger to pick 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 it’s a must to consciously faucet with two fingers as an alternative of 1 to switch the presets, as to stop you from by accident altering them.

Within the common movement of issues, VoiceOver principally feedback on the centered ingredient 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 provide audio suggestions on some interactions.

The cherry on prime is that sure timer values get purple out aloud. Within the yellow and inexperienced phases you get a voice immediate each minute. The part transitions get introduced as effectively. Within the purple part there may be 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’d add some configuration choices at a later level.

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

Conclusion

I’d say my implementation is 95% excellent. There are some edge circumstances nonetheless – which I can not do a lot about – the place VoiceOver will insist of talking one thing that it wouldn’t must. Sadly there isn’t any approach to inform Accessibility to “shut it” for sure instances when there’s something extra necessary happening.

It price me numerous 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?
