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 therapy. On this article I describe a number of the issues I realized 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 middle and the section “site visitors gentle” on the backside.

The principle interplay gesture is to horizontally swipe over the LED digits to alter the timer. This sort of gesture shouldn’t be potential when VoiceOver is lively as a result of there you’ll be able to pan over the display screen to rapidly 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 shouldn’t be working. This manner you’ll be able to 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 section buttons. #2 substitutes for the lengthy press. The rationale is that it’s important to consciously faucet with two fingers as an alternative of 1 to change the presets, as to stop you from unintentionally altering them.

Within the common stream of issues, VoiceOver mainly feedback on the centered ingredient and after a brief pause additionally reads out the accessibility trace that tells the person what interactions are potential. I additionally used VoiceOver’s announcement notifications to offer 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 section transitions get introduced as properly. Within the pink section there’s an announcement very 15 seconds, with the ultimate 10 seconds being accompanied by beeps.

That felt like an affordable 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.


I’d say my implementation is 95% good. 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 strategy to inform Accessibility to “shut it” for sure occasions when there’s something extra vital happening.

It value 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, particularly 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?
