Does anyone have an idea or example on how to track if the user is shaking their head. I want to make a filter where if you shake your head you trigger something. But I can't really seem to figure out on how to track if the user shook their head. Any help would be appreciated!

This might help but there is a script for Head nodding you can change it up and just change it for both X-Axis and Y-Axis that could help.

if you do have experience scripting

this part right here

duplicate it and change up the axis
```
var headForwardNoY = new vec3( headTransform.forward.x, 0.0, headTransform.forward.z )
    var dot = headForwardNoY.dot( headForward );
```
