With 3D Motion Sense technology, it looks like our way of interacting with phones is going to change soon. Touchless interactions have a promising future for sure, with Apple’s most ambitious product to date— AR glasses—already under development.
While the True Depth technology on the front iPhone camera does allow you to add eye-tracking features to your applications, it is only available on iPhone X and above. Luckily, we can leverage Firebase’s ML Kit to help us. Specifically, ML Kit’s Face Detection API does a lot more than just face detection on the device. 

You’ll be able to wink or turn your head to perform a swipe or touch.

Some of the features that ML Kit’s Face Detection supports are:

Face tracking

2 ways to integrate the feature:

* Copy your app's coding to this app;

* Copy this app's code in your app;
