We had multiple internal prototypes, but decided not to proceed due to the limited achievable accuracy (for most conventional depth sensors), low demand.

In principle it could proceeded through custom development, so if you have some particular volume demand - please feel free to contact us directly through feedback form.

I found this setting in the nuitrack.config but couldn´t find any explanation for it: “CPU”: { “MaxLoad”: -1.0 }, I guess -1.0 means no restriction at all, but how could I set it to, e.g.

To enable load restriction you can set this parameter to the value between 1.0 and 0.0, lower value means lower CPU usage.

If this still happened, then using the CameraId parameter, you can insert the RGB stream index from Astra Pro to solve this problem.

Supposedly it should draw circles on shoulders, wrists, waist and knees.

I worked my program up from these simple but great examples found on git hub: link bad performance video sample 9 Lenovo Yoga slim 7 specs: Processor: Intel Core i7-1065G7 @ 1.3GHz RAM: 8 GB Anyway, my questions are: Can performance be drawn back by just using other resources like ImGUI?

Could you please try to execute your code without Nuitrack AI and check if there is any difference.

Hello, Is it possible to completely disable the tracking of a skeleton at runtime so that it does not consume any computing time?

We are developing games that only need tracking of 1 skeleton.

However, we have a game menu where we need hand tracking 2x.

So, we are doing this: skeletonTracker.SetNumActiveUsers(2); However, tracking a 2nd skeleton in the game causes performance problems.

The value read in skeletonTracker.GetProcessingTime() doubles with 2 skeletons from 20ms to 40ms.

Something like: skeletonTracker.GetSkeleton(1).enabled = false; would be very useful

I may found an answer to my question  We are using: skeletonTracker.SetAutoTracking(true); skeletonTracker.SetNumActiveUsers(2); I guess setting AutoTracking to false and start/stop the tracking manually would do the job.

You can try to run the following command from the Windows PowerShell as Admin (Win+X): cmd /C icacls "C:\\Program Files\\Nuitrack\\nuitrack\\nuitrack\\data" /grant %USERNAME%:F /T or edit permissions in folder properties → Security → Edit
