Question XRHand Oculus Menu Pinch Gesture

I have installed the packages needed to Quest 2 hand tracking including the XR Interaction Toolkit, XR Hands and the sample that includes the Hand Visualizer.

When I run this on my Quest 2 and set down the controllers, I see the hands. I am able to make the right hand menu gesture and the oculus menu appears and I can choose to resume / quit the app.

When I do the same gesture on the left hand, the menu icon appears and then goes away when I pinch.

What I need to know is how to do something in a script when that happens. How do I hook into that left hand menu pinch gesture?

 

I don't think it's reasonable for every developer to implement this themselves. The right hand is reserved for the Oculus menu, that's correct. What should happen for the left hand is that when executed it should be the same behavior as when the start/menu button is pressed on a left Quest controller. There should be a simple binding that can be used with the XR Interaction Toolkit / Input System where menu button presses can be detected, regardless of whether controllers or hands are used.

Others are having trouble finding documentation and getting this to work as well, (see here)

What I'm currently doing

Code (CSharp):

1. private bool _menuPrev;
2. private void Update() {
3.     var state = OVRPlugin.GetControllerState4((uint)OVRInput.Controller.Hands);
4.     bool menuGesture = (state.Buttons & (uint)OVRInput.RawButton.Start) > 0;
5.     if (menuGesture && !_menuPrev) {
6.         ToggleMenu();
7.     }
8.     _menuPrev = menuGesture;
9. }

But this relies on using the Oculus Utilities, I'd much rather have a cross-platform compatible way of checking for menu button presses that supports hands (with XR Interaction Toolkit)
