I can confirm that I was able to get pupil diameter using WaveSDK while running a Unity App on the Headset. Our research team needs pupil diameter via PCVR streamimg. If we could get an estimate of when this will become possible it would really help us @VIVE_chengnay.

Hi @VIVE_chengnay, if OpenXR does not support it, is there a way we could get pupil data by changing the VR Runtime (in Unity), even it it's a lot of work. We want to start conducting tests in mid june, so it is urgent for us. Is there any ETA for when pupil size is coming to PCVR or any way at all to get the data while streaming PCVR? While testing I did manage to get pupil data only when running in the headset with Wave SDK and it did feel like it was updating about once per second. Unfortunately we need the data through PCVR, because there are other system(s) running on the PC which interact with Unity and because our environment is performance intensive.

@VIVE_chengnay it's OpenXR. If switching to something else would help, I wouldnt mind switching. And how bad of a latency do you think (if less than 1 second it could be okay). My main concern with the background service idea, is that I might not be able to develop it, since its outside my field of expertise.

Thanks @VIVE_chengnay for looking into it for us. If no solution is available, do you think it would be possible to code a custom solution for this? Something like an App running a Background Service on the XR Elite to send the Pupil Size to a Unity App running on a PC, which is connected to the same Wifi Network? Since I am a noob in mobile development, I would try using libraries like this: https://github.com/nintendaii/unity-background-service

Hi @VIVE_chengnay, we are developing for PCVR. Is there any way for PCVR to access the pupil dilation. Even if its a hacky work-around it could solve our issues.

@VIVE_chengnay I just tried yesterday and while I could access pretty much everything else, trying to get pupil dilation always returned a 0 for me. Is there any way to get Pupil Dilation through wireless streaming on a PC? Is the LivePreview thing an option? Any help would be much appreciated.

If you check here: https://docs.vrcft.io/docs/hardware/VIVE/sranipal It does say that SRanipal version 1.3.6.8 supports the XR Elite. I will look further into that and maybe get back here for anybody else looking for an answer.

We have the same issue as well. We purchased the XR Elite only because it can track pupil diameter with the full face tracker module. How do we access the data from Unity (when streaming)... If you find a solution please let me know @JonathonHart and @Thxkew. Would be very nice if someone from Vive answered.
