Detect custom Hand gestures

Hi everyone,

I am quite new to Oculus and Unity but I managed to set up a project and detect the pinching gesture.
According to the Reference Guide (v16) the OVRHand Class has only 3 public functions and all is about pinching.

In my project I want do use some more gestures. So I thought I could implement my own similar to the way it was done in OVRHand. The Pinching Functions get the HandState from OVRPlugin.HandState.

So I have two questions. Am I on the right track for detecting new hand gestures? And where can I find a detailed documentation about OVRPlugin.HandState? I would like to know which functions it offers for use.

Thank you.
