Dragging on mobile apps

[lgnacio]

On mobile, you can sort the order of list (or grid) contents by using drag and drop operations as in Example 1 below.
Example 1: https://unitid.nl/windowsphonepatterns/uap_pattern/drag-and-drop

This content doesn't work with a single pointer, only drag and drop.
However, it helps anyone who has a hard time performing path-based gestures in the following ways.
1.setting(iOS)
2.Accessibility
3.Touch
4.To Activate "AssistiveTouch"
5.Custom
6.Hold and drag

Example 2: https://youtu.be/RNSplpCh_A8

Is it a sufficient technique(2.5.1 Pointer Gesture or 2.5.7 Dragging) to use "AssistantTouch" to order the list (or grid) content in Example 1?

You can't rely on an OS-level feature like "AssistantTouch" or whatever, as it's not available on all platforms (similar conceptually to saying "no, mouseKeys is not a substitute for making something keyboard-accessible"). Sites need to provide an additional method that does work with single pointer taps.

Do you know an alternative method for this case(Example 1: https://bit.ly/33VYN5u) on mobile?

[patrickhlauke]

conceptually, an option is to provide a separate explicit "reorder" button. when activated, show an up and down extra control for each item, and a "done" option.

[lgnacio]

I know it's theoretically possible. However, I wonder is possible to implement it with technology. It's possible on the Web. Is it possible on "mobile app"?

[patrickhlauke]

why would it not be possible in a native app?

randomly, came across this article today https://medium.com/android-microsoft/accessible-reordering-for-touch-devices-e7f7a7ef404

It was very helpful! thank you.

Proposed working group response:
Thank you for your comment. While applying specific assistive technology settings like assistive touch on iOS may alleviate the dragging problem for some users, these options are not universally available and will not qualify as Sufficient Technique for a wider accessibility baseline covering different platforms and user agents.

Hi everyone, the group discussed this today and agreed this response (slightly modified from the draft):

Thank you for your comment. While applying specific assistive technology settings like assistive touch on iOS may alleviate the dragging problem for some users, these options are not universally available and would not qualify as Sufficient Technique for a wider accessibility baseline covering different platforms and user agents. That said, until WCAG2ICT is updated, the group has not provided any guidance on applying the new SCs to native mobile apps.
