Is the tracker still tracking?

[steve69]

Hi there,

how can I checkif a tracker is no longer tracking?
Would like to switch to a second one.
Is this possible?
Use Unity and the ViveInputUtility or SteamVR

Thanks

Stephan

@steve69 By looking at SteamVR, if it is tracking, the tracker icon will light up.

If lost tracking, it will be flashing.

Is this what you are looking for?

Generally, yes. But how do I query that in Unity?

But I have the impression that the tracker still supplies dirty position data before it reports that it is no longer tracking. Can this be recognized faster so that I can switch to another tracker at the right time.

By using VIU, you can try the following API to know whether the pose is valid or not.

VivePose.IsValidEx(TrackerRole.Tracker1) <--- It will return true if pose is valid

Thank you for the info.
That's exactly what I was looking for.

Is there somewhere a description of what the other classes and functions in the VIU can be used for? Unfortunately I haven't been able to find it yet.

Currently, there is no place to look that up, but you can always ask questions when you need help. 🙂
