Standards for two-finger touch gestures?

Question

I tried to define the follow gestures in a remote desktop app. (Native Touch vs. Cursor Mode) I am worried that the two finger behaviors are too difficult.

One-finger (native touch)

1. One-finger tap = left-click
2. One-finger long-press = right-click
3. One-finger double-tap = double-click
4. One-finger tap & press = drag-and-drop

Two-finger (cursor mode)

1. Two-finger pan moves mouse cursor around
2. Two-finger tap = click at cursor location
3. Two-finger long-press = right-click at cursor location
4. Two-finger double-tap = double-click at cursor location
5. Two-finger tap & press = drag-and-drop at cursor location

The question

Which published standards can I use to assess whether this is a standard implementation, or to conduct a heuristic review?

Answer 1

If you are only looking for resources to review and compare against, I would suggest looking at most popular devices in the market today. Below is the list I was able to find:

1. Windows Touch Gestures Overview
2. New gestures you have to master to tame Windows 10
3. Use Multi-Touch gestures on your Mac
4. Google Design Patterns - Touch

Answer 2

Here's an illustration of various gestures—but not necessarily what these gestures do. Does this help you to search/research/ask questions?

I just found this illustration as the answer to a different question.
