Detect User Presence (HP Omnicept)

Hello,

Is there any way to detect if the user is wearing the headset (HP Reverb G2 Omnicept)?

I am using Windows Mixed Reality as the OpenXR runtime, and even if I don't wear the headset, the headset tracks movement.

My goal is to figure out when the user takes off the headset (and when the user re-wears it) so I can make changes to the application at runtime.

Any help will be appreciated.

Thank,
- Atif
