ARKit tracking eyebrows with a unified motion instead of individually.

I'm experiencing this issue as well.

I've spent a couple of weeks scouring the internet and asking questions in various places, and it's as though nobody's noticed this or thinks it's a big deal.

I guess 99% of people don't use their eyebrows for emoting?

All I can assume is that the hype around the ARKit face tracking was coming from hobbyists who played with it like a toy, and that it actually has no real usefulness as an actual indie-professional solution.

Happy to be proven wrong, but I'm already in the process of setting up a production pipeline using Faceware instead.

I experience it as well. All the software I have tried, none of them have independent eyebrow tracking. I reached out to some devs of those softwares Unreal LiveLink, iFacialMotion 3DFaceMotion, VBridger, Vtube Studio, Waidayo to name a few and they all say it is a problem with the arkit. Some of them even send bug reports. This was around 1 year ago already. I would love to see this fixed, as it would widen the usage of great tracking from the iPhone. All I was able to find out is, that this issue started with iOS 12. I would love more people to point this out, to give this some more attention. Since the movement of the eyebrows are one of the most important body parts to make a variety of expressions possible.

This issue is still happening. I have tried all the major available apps to do face mocap on the iphone now. They all have the problem of both eyebrows moving at once. We are using iphone 15 PM

It has been 2 years with no response from Apple on this?? I guess apple has given up on face capture.

Our company had been testing the iphone to see if we could do mocap with it. This problem makes iphone unsuitable for our professional mocap needs.. We will have to look for a different face mocap solution

This still seems to be the case a whopping 4 years later. There HAS to be something that can be done. I've heard of people talking on Reddit about how iPhone tracking is GOOD for individual eyebrow tracking.
