 Hello, so I'm sitting today with Professor Agnieszka Szarkowska, who is a researcher on the visual translation and subtitling in particular, and she is well known for her research using eye tracking. Maybe we could start by explaining to those of our viewers and listeners who have never heard of eye tracking. What is it and how does it work? Yes, hello, good to be here. So eye tracking is, in simple terms, this technology that allows us researchers to know where and for how long people are looking. And it can be used out in the real world, for instance you can get those eye trackers or eye tracking glasses, for instance, lots of marketing departments use that, where you take a person to a supermarket, let's say, and you see how they're interacting, interacting, where they're looking on the shelves, where you want to place certain products and whether they're looking at the logo in the right way, etc. So there's a lot of marketing research with eye tracking. The eye trackers we have been using are mostly ones that you actually use in the lab. So as a participant you come to the lab, you sit in front of a screen and there's an eye tracker attached somewhere. It basically looks like a panel, there's a camera or two cameras and some infrared light illuminators and they light your eye and using some special algorithms that I'm going to talk about. They know where on the screen you are looking. And previously eye trackers and eye tracking research was very invasive. People would wear those head-mounted eye trackers and they would have to have this bite bar so that they don't move. Now eye tracking research is much more user-friendly. Our participants just come and sit in the lab and watch subtitle films. Although we have this one contraption that is called a chin rest which basically is this device that you just put your chin there and again the whole idea is that your head doesn't move so that we can track precisely where you're looking.
