[unko]

Thank you very much.
It's vive wave xr pulgin essence 5.6.0-r.10.2
I have also installed vive console for steam vr from steam on another project and have used SR anipal. these are the two things I have in mind regarding eye tracking.

Hi @unko,

Update rate per eye is 1 sec.

Is this ok for your development?

[unko]

Thanks for the reply.
Its update rate is a big issue because I want to get real time of pupil changes.😢

It needs to be around 50Hz.

[VIVE_chengnay]

Hi @unko,

Could you share your purpose of getting real time pupil data?

50Hz is for each eye? or both eyes?

If 50Hz each eye means 1 sec update 50 times.

For both eyes means 1 sec update 25 times per eye.

Which is your need?

[unko]

Thank you for your reply.
The reason I want to get the pupil diameter at 50Hz is to investigate the responsiveness of the pupil diameter to what is projected by the XR(VR).
Therefore, I would like to reliably capture about 50 changes per second (once every 0.02 sec) for each eye.
I am currently developing this in a big hurry and if you think you can solve this problem quickly, please let me know how to do it.
If 50Hz is too difficult, we can work with about 25Hz. Anyway, I would like to have more than 10Hz.

Hi @unko,

We understand what's your requirement and expectation, and may need to have internal discussion and estimation how we can support this and the possibly timeline.

Might get back you shortly next week.

Thanks.

Thank you for your consideration.
I am looking forward to it.
