Our TestFlight request has been rejected bucause a reviewer could not signin with Cognito HostedUI. We have activated AWS Cognito Advanced Security, and the reviewer's signin trial was detected as a high-risk activity. The Cognito user account which the reviewer used had valid email and password. So I guess the reviewer tries some common bad signin evaluations. How can we pass the review? The reviewer could not provide us IP information, so we cannot exclude their IP. In addition, the Advanced Security should be active due to security requirements. I believe Cognito and its Advanced Security is common and others used them like us.

How correct are the gaze direction values for eyes that are open outward or close inward? The values for the right eye and the left eye seem to be averaged out. I use the x component of the eyenode for the gaze direction as follows. leftEyeAngleX = asin(leftEyeNode.simdTransform.columns.2.x) leftEyeAngleX = asin(leftEyeNode.simdTransform.columns.2.x)

Which is the best way to obtain the horizontal (x-z plane) rotation angle of eyes? For example, for the right eye rightEyeNode.simdTransform = faceAnchor.rightEyeTransform and then asin(rightEyeNode.simdTransform.columns.2.x) or rightEyeNode.eulerAngles.y

Is there any way to know the coordinates of the pupil in ARKit?

In the official documentation, the orientation of the eyes is determined by the center of the eyeball and the pupil. Is the position of the pupil extracted from the image? Is an infrared sensor also used to extract the position of the pupil?
