Re: 2.5.1 Multipath gestures query

Neither of those is a failure for the following reasons:

1. The Success Criterion applies to gestures in the author-provided content, not gestures defined by the operating system, user agent, or assistive technology.

2. Pickers do not require a path based gesture. Only the start and end points matter, not any intermediate points.

Also, that page does not state that using left and right swipe gestures or z gestures are regarded as a failure. Did you read that somewhere else?

Subject: [WebAIM] 2.5.1 Multipath gestures query


The 2.5.1 Multipath gesture
<https://www.w3.org/WAI/WCAG21/Understanding/pointer-gestures.html> states
using left and right swipe gestures or z gestures are regarded as a failure.
The question I have which you see in a lot of applications for native mobile

1. Page scrolling - this could be a single finger or multiple finger
swipe gesture depending on OS and Assistive Tech being used.
2. Pickers where you have to perform a up and down swipe gesture to
change the value.

As I read this SC, the above are failures if there isn't another means of supporting single point gestures. I wish to ensure that my thinking is on the right path and does this means the mobile vendors documentation and/or API's be adjusted (assuming I am correct with my understanding)?
