So you are saying that this OpenAmount isn't really related with the pupil size? I'm confused about how this could be, since you already had such feature in Magic Leap 1. If not, when is this feature planned to be released?
On the other hand, is there a way to access the claimed 90Hz data? This is what I found, in Eye Tracking | MagicLeap Developer Documentation.
Eye tracking on Magic Leap 2 lets developers design natural and intuitive input and interaction scenarios. The Eye Tracking API provides information about what the user is looking at as a single eye-gaze ray (gaze origin and direction) at approximately 90 FPS (90 Hz). For eye tracking to work accurately, each user is required to go through an eye tracking user calibration.
If not, 60Hz data might also work in my case, but I'm still not sure if accessing data in the Update() method indicates that the sample interval will not be a constant. The app I'm developing needs to use the ML Camera to capture an image every 1.5 second, which seems to be causing delays in the app. I tried to put it in a background thread but the problem remains. I do want the data to be sampled at a constant interval. Please advise.
Thanks!
