Accessibility in SpeakerClock 1.3.1 | Cocoanetics

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

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

The primary interplay gesture is to horizontally swipe over the LED digits to alter the timer. This sort of gesture just isn’t potential when VoiceOver is lively as a result of there you possibly can pan over the display screen to rapidly get to the new spots of interactive components.

I solved this by having individually adjustable sub-elements for the minutes and seconds whereas the timer just isn’t operating. This manner you possibly can swipe vertically to regulate the minutes and seconds individually.

There are three sorts of normal 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 operate 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 a substitute of 1 to change the presets, as to forestall you from by chance altering them.

Within the common move of issues, VoiceOver mainly feedback on the centered aspect 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 high 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 properly. 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.


I’d 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 isn’t a method to inform Accessibility to “shut it” for sure instances when there’s something extra necessary occurring.

It value me a variety 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 would possibly make sense?
