Re: [Design] [Engineering] [Research-Internal] Affordable eye tracking

Indeed, on desktop mouse cursor can be a decent proxy for gaze. I can't remember if it was the particular paper you've quoted where I read about it, but I seem to recall that the correlation varied quite a bit from one person to another. Essentially some people point the mouse to where they're looking, but others don't. This paper by Microsoft about cursor position is also relevant: https://phabricator.wikimedia.org/T165272#3955001 but it shows the limitations of predicting things based on cursor position when the person doesn't know what they're looking for when they land on the page. It works really well for the use case of people looking for "Facebook" on Bing to go to Facebook. Which probably has some muscle memory to it, i.e. people who do that already know where they're going to move their mouse to. This is the paper that got me interested in gaze tracking for performance: https://phabricator.wikimedia.org/T165272#3933730 It has limitations in terms of methodology, with people watching videos and playing a guessing game instead of having a more natural browsing experience, but the results are impressive. Enough to make me want to investigate what people look at on a Wikipedia page as it's loading, to inform our decisions about how we prioritise page elements. The upside of doing a study with a device like the Tobii 4C is that we can also verify at the same time the correlation between gaze and cursor position.
