Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

How to get tracking quality for the headset?

Hello,
We're working on a game that take place in a big real environment, something like a warehouse. We need a way to get the tracking quality. I know it's possible for controllers, but I don't find anything for the headset (which is the most important things for us).

In Unity the WorldManager class is unfortunately useless because the state variable has only two values: Active and Inhibited. Maybe the native SDK has something better?

The best thing would be a simple variable using values between 0.0 and 1.0 to represent the tracking quality. With a value less than 0.3, we can ask to our users to take care, preventing them to lose the tracking.

It's also a feature very useful for regular VR experiences. Feel free to contact me in PM for additional informations.

  • Hi, the headset is wired connected to the pc but motion controllers are wireless. Could I ask you about how to detect controllers' connection quality as you mentioned?
    We can figure your goal by that, then try to give useful information.

  • Hello,
    Thank you for your answer. Sorry my message wasn't enought detailled. I know that the headset is connected to the PC and the controllers wireless and I don't have any issue with that. My headset/controllers are working fine, they're all detected.

    I want to detect the quality of the tracking for the headset and I would like to know if an API exists or not for that. For controller there are already something, but not for the headset.

    What do I want?

    It's only related to the tracking on the headset, not controllers.

    When a user use a Windows MR headset, it can loose the tracking if it looks a wall too close, or for other reasons. I want to find a way to prevent the user to loose the tracking and for that, the only solution is to try to detect a tracking loss to inform user to be careful.

    For instance, it could be nice to have a variable or a function to query to get the tracking quality. By this way, I'll be able to inform the user that he'll loose the tracking very soon. He'll be able to move in another place where the tracking quality is better.

    I know how to detect a tracking loss, using WorldManager.state. But this information is not enough because it's just "Inhibited" and "Active".

    So my final question is: Do you know if there is a function to call to get the tracking accuracy of the headset.

    Thank you.
