Learn how you can set-up motion capture (mocap) in High Fidelity using Vive trackers.
This page guides you through the process of configuring and calibrating Vive trackers for motion capture (mocap) in High Fidelity. Even if you only have one HTC Vive Tracker, you can use it to control your Avatar or even attach it to an object like a guitar!
You will need to purchase Vive trackers to set-up a mocap system for yourself in High Fidelity. If you bought a Vive Pro, you can use up to 4 lighthouses for better tracking, other wise the Vive with the standard two light houses will also provide good support. Depending on what kind of motion capture you’re looking for, the number of trackers needed differs.
If you are a performer and need the use of your hands instead of the Vive controllers, two extra trackers are needed for your wrists. If you need to track your head but not use a HMD, then you also need one tracker for your head.
To use the trackers, you need to strap them on to different parts of your body. You can purchase straps of different lengths for different purposes from here:
For information on how to pair the trackers, refer to https://www.vive.com/eu/support/accessory/category_howto/pairing-vive-tracker.html
Once you’ve purchased the number of trackers and the straps for your requirements:
Make sure your Vive headset, hand controllers, and Vive trackers are properly connected to SteamVR.
Securely attach the Vive trackers to your body as shown in the image.
If you are in HMD mode, pull up your tablet or if you are in Desktop mode go to Settings > Controls > Calibration .
Set your tracker configuration to one of the following options:
Click "Apply and Calibrate".
When you setup your Vive and choose which way to point the arrow as your reference, it is important that you face this same way during the calibration. This will be fixed in a future version. If you can not remember which way that arrow was, you can press the Vive System Menu Button and look on the ground for a marker. This should be facing the same way the initial arrow you created during the Vive setup is facing. This is important to make sure your joints are orientated correctly.
Stand in a T-Pose until the timer counts down to zero:
Use HTC Vive Devices in Desktop Mode: Check this box if you have a head tracker and want to use your trackers in desktop mode without having to wear your Vive headset.
Once you’ve applied your desired configuration, you can use a shortcut to calibrate your trackers without having to bring up your tablet again. To calibrate on the fly, stand in a T-Pose and hold the following four buttons together for 1 second:
Check if you’ve calibrated your trackers by moving the corresponding joint and determine if your avatar moves the same joint. Check to see that each tracker now tracks its corresponding joint on the avatar.
You can press the same buttons together for a second to remove your calibration from the trackers.
My sensor is jiggling a lot!
My sensor keeps losing tracking.
Final note: Remember to charge your trackers when you aren't using them so that you don't have to deal with a low battery tracker negatively impacting your performance.
