Get Started
Before starting motion capture, it is necessary to perform a calibration.
Once you have put on the trackers and launched Dollars VIVA, you should see an interface similar to the image below, which displays a mannequin used for motion capture and the positions of the various trackers.
Pre-Calibration
Press the C key or click the calibration button in the top left corner to enter the pre-calibration state.
At this point, please confirm that the VIVE controllers or trackers are being tracked correctly.
After confirming that each tracker is correctly tracking, you can assume the calibration pose and prepare for calibration.
The calibration pose for Dollars VIVA is as follows:
- Standing Position: Stand up straight with your feet together and toes pointing forward.
- Arm Position: Stretch your arms straight out to the sides, relax your wrists, and ensure your palms are facing forward.
- Head Position: Look straight ahead with your eyes level.
This is the case when you are holding the HTC VIVE controllers.
This is the case when you are using the HTC VIVE Trackers.
