Webcam Eye-Tracking
Yes, it's really possible only with webcam
Traditional eye-tracking requires dedicated hardware (infrared camera) to detect retina position and predict gaze point location. Webcam eye-tracking allows you to get the same information out of a traditional webcam, which is built-in in most of nowadays devices so that you can conduct your studies 100% remotely (see: Eye-tracking study - offline vs. online).
The precision of data obtained from this method is proven to be around ~100px (the size of a button on a website). The method allows for large-scale studies and quick turnaround, which is perfect for quantitative research.
