SDraw driver_leap for VR controller emulation

The above video, based on SteamVR's tutorial,

IMO explains nothing useful for hand tracking.

driver_leap SteamVR Gemini Hand tracking driver
- Sep 2020 pointer from forums.leapmotion.com
- described at ultraleap.com
- Shodah:

"using it a lot to emulate the Index controllers,
  best to download the driver and have a play.
  Takes some time getting used to it,
  but works in every SteamVR game just fine"

my experience

driver_leap installation instruction seems outdated

setting "activateMultipleDrivers": true, gets reset to false (by Steam?)

Using SteamVR ultraleap hyperion

that version works with Ultraleap's Aurora game on Steamver

I cannot keep hand tracked laser pointer on controls while gesturing

gesturing rarely worked and never usefully.

Better control using cyan dot aimed by headset gaze:

... after toggling controllers off in Leap Control:

Controllers must also be toggled off for Aurora

here is the least bad gesture example video

Wanted:  headset gaze pointer with gesture control buttons

- to select something you bend your index finger as if you were pulling a trigger

At least in VRChat,
- by default left thumb and index pinch opens the menu left thumb
- middle finger acts as your movement if you hold and drag slowly
- a regular pinch but pretty quick acts like a trigger button to select things
