Calibration for eyeScrollR
For this tool to work properly, please use it on the monitor that will be used for eye-tracking.
Place the browser on the screen exactly as it will be during the study, and refresh this page before you start
It is strongly advised that you deactivate the smooth scrolling feature on your browser before you run the experiment, and before you calibrate
Once you have a scroll_pixels value, take a screenshot of the whole screen, and use it in the scroll_calibration_auto function (or take measurements by hand)
Please scroll down a bit to get a scroll_pixels value
