alternative for dragging - clicklock / draglock #4000

Open gundulaniemann opened 1 month ago

gundulaniemann commented 1 month ago

Users relying on an alternative for a dragging motion usually use the capabilities of the Operating system to support them. The relevant operating systems provide an option like 'clicklock' or 'draglock' which replaces a dragging motion by consecutive clicks, we´here the duration of the first click can be customized to yield a clear distinction from a 'usual' click. The web page then still receives dragging events, so no additional effort needs to be done by the author.

Some background: Windows provides clicklock, Mac offers draglock, for Linux clicklockd is available, on iOS custom gestures can be used, and for Android there are add-ons which can be used.

I suggest to add the following sentences to the understanding document: "Users relying on an alternative for a dragging motion usually use the capabilities of the Operating system to support them. All relevant operating systems provide an option or an extension for replacing a dragging motion by consecutive clicks or taps. Therefore an author can rely on the operating system support. Additional alternatives add convenience for users with dexterity and motion precision issues. We recommend to provide such alternatives specifically for users with slight or occasional dexterity issues."

So this would make the SC always pass, making it useless?

Please see the prior MATF response to my prior issue on this exact topic.

In a separate issue I also registered concern with some of the wording in the draft document, which was resolved sufficiently to be closed.

We have been caught a bit by the technical progress. Still I feel it is beneficial to have alternatives.

I read through both issues and see two points related to my suggestion:

We investigated Windows, Mac, Linux, iOS, and Android. They all provide this support, either directly or via an add-on (free of cost).
