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 number 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 mild” on the backside.
The principle interplay gesture is to horizontally swipe over the LED digits to vary the timer. This type of gesture will not be potential when VoiceOver is lively as a result of there you’ll be able to pan over the display screen to shortly 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 fashion you’ll be able to 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:
- 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 part buttons. #2 substitutes for the lengthy press. The rationale is that it’s important to consciously faucet with two fingers as a substitute of 1 to switch the presets, as to stop you from by accident altering them.
Within the common circulation of issues, VoiceOver principally feedback on the targeted factor 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 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 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 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% excellent. There are some edge circumstances nonetheless – which I can’t do a lot about – the place VoiceOver will insist of talking one thing that it wouldn’t have to. Sadly there isn’t any technique to inform Accessibility to “shut it” for sure occasions when there’s something extra necessary occurring.
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 would possibly make sense?
