Re: Vibrating phone on invalid input entry

Hi All,

Good discussion. While right now this is discussing what I presume is a
native app on iOS, the W3C is currently working on a Vibration API (Second
Edition) (https://w3c.github.io/vibration/) so that web developers could
recreate this feature in their web-apps, and the question did come up about
accessibility considerations for this at the APA (
https://www.w3.org/WAI/APA/).

As others have noted, there really isn't a direct WCAG Success Criteria
today that addresses (with any specificity) this scenario, and it is likely
a good candidate for the current effort underway on WCAG 2.1. Having only
one mode of either input, or here output, has long been a principle that
we've recognized as being inaccessible, and so while we may not have a
specific WCAG SC to point to (as Rakesh notes), I would suggest that it
would likely be covered under the Principle of Perceivable, and so if
nothing else it is failing the spirit of WCAG, even if we don't have a
specific Success Criteria to point to.
