Cannot retrieve the pinching state of my gesture through OpenXR

Recommended Posts

I am developing a PC VR application that runs on my HTC VIVE Focus 3 via Vive Business Streaming.

During the development of hand gesture recognition by OpenXR, InputDevices.GetDeviceAtXRNode(node) cannot detect my input device, and handDevice.TryGetFeatureValue(CommonUsages.grip, out float gripValue) fails to return the value of my pinch gesture.

However, handDevice.TryGetFeatureValue(CommonUsages.devicePosition, out position) is able to retrieve my hand position.

Why is this happening? Is there something I haven't configured correctly? Or is it possible that I wrote the code to retrieve the pinching state incorrectly?

In the code where I retrieve the gesture's position, handDevice = InputDevices.GetDeviceAtXRNode(handNode)
