DEMoCap can be used with Meta Quest HMDs to do limited motion capture. With these HMDs only upper body motion capture are usable with the following features present (depending on your Quest model):

• Head tracking
• Hand tracking (controller or hands only)
• Eye tracking
• Face tracking
• Finger tracking

Right now DEMoCap does not yet run on the Quest itself. Instead you have to connect the Quest to your PC where DEMoCap runs. This connection can be either wired or wireless using one of these programs:

• WiVRn: Wired and wireless for Linux.
• SteamLink: Wireless for Windows and Linux.
• ALVR: Wireless for Windows.
• Occulus Link/AirLink: Wired and wireless for Windows.

The most stable out of these is WiVRn. There controller and hands only works good. SteamLink has problems with finger tracking breaking the capture on Linux. Occulus Link/AirLink pretty much can't do finger tracking at all. Hence with controller mode various solutions are working while with finger tracking WiVRn seems to be the most reliable one. You have to try for yourself what works for your setup.
