PSA: Don't spend $30k on eye tracker for dwell time research! Get a @gazepoint, download OpenSesame, and use the built-in PyGaze toolbox by @esdalmaijer & @cogscinl for seamless eye tracking on one machine. (Then cite and donate accordingly.)

@QuERBYLAB @shari_alaina @court_beard have all joined the affordable eye tracking revolution. DM me if you're curious. And read this if you're skeptical: https://peerj.com/preprints/585/ 

Or check out this awesome paper using $100 Eye Tribe. It's gone (acquired by semi-Evil tech giant), but @gazepoint works as well in my experience. https://www.sciencedirect.com/science/article/pii/S0306460319301789
