Now you can totally function SpeakerClock with no or low imaginative and prescient. We gave SpeakerClock the complete Accessibility therapy. On this article I describe a few of the issues I realized 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 huge as attainable within the heart and the section “site visitors gentle” on the backside.
The principle interplay gesture is to horizontally swipe over the LED digits to vary the timer. This sort of gesture will not be attainable when VoiceOver is lively as a result of there you possibly can pan over the display to rapidly get to the recent spots of interactive parts.
I solved this by having individually adjustable sub-elements for the minutes and seconds whereas the timer will not be working. This manner you possibly can 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:
- double-tap with single finger to pick a component
- double-tap with two fingers to carry out a “magic faucet”
- draw a Z with two fingers to “escape”
I used #1 for the single-tap operate of the preset and talking section 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 change the presets, as to forestall you from by chance altering them.
Within the common circulation of issues, VoiceOver mainly feedback on the centered factor and after a brief pause additionally reads out the accessibility trace that tells the person what interactions are attainable. 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 nicely. Within the pink section 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 would 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% good. There are some edge instances 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 method to inform Accessibility to “shut it” for sure instances when there’s something extra essential happening.
It value 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, particularly those that are visually impaired and might 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?
