Meta Quest 2 and Meta Quest Headset Tracking
Meta Quest headsets utilize inside-out tracking with 6DoF (six degrees of freedom). If you turn tracking off from the settings panel in VR, you’re actually switching from 6DoF tracking to 3DoF tracking. Each tracking type is explained in more detail below.
- 3DoF: 3 Degrees of Freedom (DoF) Tracking can track rotational movements around the x, y, and z axes. 3DoF only tracks the direction that you are looking (ex: up/down, left/right), but doesn't track position as you move around the room.
- 6DoF: 6 Degrees of Freedom (DoF) Tracking adds the ability to track positional movement. With 6DoF, your headset will track the direction you are looking (as with 3DoF), and also your position as you walk around the room.
Here’s a simple test to see what kind of tracking you have enabled in VR: if you can move closer to or further from an object, that means you’re using 6DoF tracking. If you can only look around, but not actually move towards anything, you’re using 3DoF tracking.
Optimal Tracking conditions
In order for the tracking on your headset to work best, your playspace should have bright, even lighting. As a general recommendation, you’ll want to have the same amount of light as you would have in the living room when you have guests over. If the lighting in your room is too dark, your headset may lose the ability to use 6DoF tracking.
The purpose of 6DoF Tracking
6DoF tracking allows the movements you make in the real world to translate into VR. As a result, many apps, games and experiences require 6DoF tracking to function. This includes the Guardian boundaries designed to help you stay in your play space while you’re using your headset.
To help avoid injury or damage, you should only use your Meta Quest 2 or Meta Quest in a stationary, standing or seated position if you turn off 6DoF tracking.
What to do if Meta Quest 2 tracking is lost
When 6DoF tracking is unable to function in your environment, you’ll get an error message to alert you that tracking was lost. You can choose to continue using your headset with 3DoF tracking, or you can try the following steps to re-enable your headset’s 6DoF tracking.
- Check your environment: If you need to adjust your environment so that tracking can resume, remove your headset and check to make sure that the lighting in the room hasn't changed. If it has, try turning on additional lights or relocating to a more well-lit room.
- Clear your Guardian History: If you’re having problems with tracking, clearing your Guardian history can often fix the issue. Keep in mind that if you have multiple accounts on the same headset, Guardian history will be cleared for all accounts, not just the account you’re currently using. You can clear your history from the Guardian settings panel in VR.
- Keep in mind, if you clear your history, you’ll need to re-draw your Guardian boundaries.
Once you’ve gone through the steps above to fix the issue that caused the tracking loss, follow the steps for Turning Tracking on to re-enable 6DoF tracking on your headset.
Turning Tracking on
By default, your headset will use 6DoF tracking unless you’ve turned it off in the Guardians settings panel, or lost tracking while in VR. To turn on 6DoF tracking:
