Eye tracking sensor?

Hello, this is my first post here so I hope it works out.

I'm looking for a sensor that allows me to track eye movements, preferably without having to blink so it only follows the movement of the eye, I've read there are different kinds like pupil and retina scanners, I don't know which one would work better for this project. Also it should have an SDK or some other way to communicate with android devices. So any type or model or any recommendation you can give me I'll appreciate it. Thanks.

    Welcome to the forums greentree!

    Tracking is a fascinating subject. I have done some simple object tracking experiments, but the laser makes my methodology particularly unsuitable for eye tracking! :)

    Google for some stuff on Hackaday. Quite a number have been discussed, but the "safest" ones use a small camera and vision recognition (such as OpenCV) to look for the pupil.

    Here's one for starters -- supposedly costs under $100

    Other methods using focused LEDs (and yes, even lasers) use a method of glancing the light across the eyeball in such a way that the light never enters the pupil. These are harder to build because of the precision needed for the optics.
