Getting Pupil Diameter From Vive XR Elite (Unity)

[VIVE_chengnay]

Hi @JonathonHart,

Could you provide your current ROM version?

Go to Settings>General>About(Last item on the right).

Thanks!

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 @JonathonHart,

Could you try re-calibrate eye tracking?

Are you able to get pupil diameter after re-calibration?

 

[JonathonHart]

@VIVE_chengnay The pupil diameter did work after re-calibration using WAVE on the XR Elite. But I dont think I can use WAVE as I need to support Quest so I really need OpenXR support. When will OpenXR support for pupil diameter come in?

Hi @YVORI @JonathonHart,

We heard your needs and we are doing evaluation.

Get back to you when we have the estimated date.

Sorry for the inconvenience.

Any updates @VIVE_chengnay?

@VIVE_chengnay I would also love an update on this. I am similarly looking to get the pupil dilation information from the full face tracker add on for the XR Elite using a PCVR setup running OpenXR in Unity. Thank you!

Hi @YVORI @vsr,

We might release by end of July, will keep you updated.

Sorry for the inconvenience.

Hi @VIVE_chengnay, we also very much need pupil diameter for our research project. We are building our project in Unreal 5 and for our purposes we cannot rebuild using the WAVE SDK. Do you have any updates on when this feature would be released? Would it also be possible as a stop gap solution to take code from the WAVE SDK and import it as a custom C++ script in Unreal?

Hi @VIVE_chengnay, are there any updates on the pupil size tracking yet?

Is the feature still coming to PCVR?
