Using an HMD for Motion Capture
You can also use an HMD for motion capture.
Please open the options and check "Use HMD."
Launch Dollars VIVA, and you will see the headset displayed in the program.
Afterward, you can use Dollars VIVA as usual.
If you want to use VIVE Tracker on your head for motion capture instead of an HMD, please make sure that this option is not checked.
