I reached out to several users and intend to contact others. My intention was to get a better understanding of the difficulty of performing swipe and drag gestures.

Today, user with severe motor impairment who works as accessibility tester gave me the following answers (translated via deep with a few corrective edits):

That's my first question:
As a sip-and-puff mouse user, is it easy, difficult, or impossible to activate, hold and move elements (such as a slider button)? And what about Swipe gestures that don't have to start at a certain point, like moving a carousel?

I use two hardware mouse replacement techniques: the Windows keyboard mouse and a mouse simulation of my small field keyboard.
For drag and drop I prefer to use the small field keyboard, because it works more reliable for my feeling. With this mouse simulation I could execute every drag'n'drop function so far.
However, this mouse simulation is much slower in all pointer movements tcompared to operating a mouse by hand. The keyboard is also very expensive. Privately I only use voice input.
I haven't yet connected the keyboard to a mobile device and can't tell if I can execute swipe gestures with it.

And my second question:
If you don't use a joystick mouse, but voice input / grid coordinates to position the cursor, is it also possible (easy, only with difficulty, not at all) to activate objects via mouse-down and move them elsewhere? And again, what about Swipe gestures?

I can only make a statement about speech input regarding Dragon NaturallySpeaking. I have hardly used any other language input (only the Windows Vista one sporadically at that time...). Also with NaturallySpeaking a drag'n'drop function is theoretically executable. However, this function is very unreliable and cumbersome. I try to avoid it as much as possible. 
I can't say whether this deficient behavior is due to NaturallySpeaking, the application, the operating system or the UI element.
I can't say anything about swiping gestures, because I haven't used a mobile device with voice control yet.

So I strongly advocate to be able to use every drag'n'drop function alternatively by simple clicks or keyboard commands.
