How to know where the user is looking on Android Screen

Hello,

How can I know where the user is looking on screen using OpenCV in Android application?
Is possible with Open CV? If yes, could where could I get development guide or sample code?

I want know the X and Y axis the user is grazing in the real time or on the widget like TextView etc…

Thanks

it might be easier for you to simply buy the technology.

implementing it yourself requires intimate knowledge of the approaches and implementations at an academic level.

in any case, quality of tracking will be poor if you only have a selfie cam to work with.
