We are trying to detect eye gaze using a simple webcam. Our main goal is to detect at which part of the screen user is looking. We are new to computer vision field and not so familiar with OPENCV. So, it's a bit confusing which algorithm to choose to reach our goal. We are hoping to get some expert opinion on which approach would be easy yet best for detecting and tracking the eye gaze(direction).
We are using python3 with opencv3. Thanks in advance.
