@virakri : How did you come up with : phoneScreenSize - width: 0.0623908297, height: 0.135096943231532 ?

Hi,

I'm curios for your example, and I clone it. I use obviously the iOS 12. I see this log

2018-06-13 10:37:48.224221+0200 Eyes Tracking[383:14693] [DYMTLInitPlatform] platform initialization successful
2018-06-13 10:37:48.297564+0200 Eyes Tracking[383:14672] Metal GPU Frame Capture Enabled
2018-06-13 10:37:48.298064+0200 Eyes Tracking[383:14672] Metal API Validation Enabled

and that 's ok. Maybe the problem is when declare the iPhone X dimension screen.

// actual physical size of iPhoneX screen let phoneScreenSize = CGSize(width: 0.0623908297, height: 0.135096943231532)
// actual point size of iPhoneX screen let phoneScreenPointSize = CGSize(width: 375, height: 812)

I understand the phoneScreenPointSize variable, but I cannot calculate the phoneScreenSize. Can write algorithm, and so calculate for iPhone 6S?

Hi,

I have downloaded built and deployed your app; the results are a bit "wild" as it were - the displayed attention point on the screen does not well match what I am actually looking at.

Is there a defined / preferred geometry - the face at one meter, centered on the screen. for example? If so, I will flange that up with cardboard and duct-tape. reading through the code does not give much in the way of a hint for such.

Thanks in advance,
