Attended this lunch-time presentation by an ex-student, Jonathan San-Diego and his supervisor James Aczel. I was interested to learn a little more about how you would go about collecting and analysing eye-tracking data, wondering what other applications it might be used for.
Fascinating presentation. Interesting challenges. you could capture what people were looking at when they are looking at the screen, but when they looked elsewhere, you had to rely on the video data. All in all, though, it was a compelling demonstration of the usefulness of eye tracking. Jonathan played an exerpt of a participant doing a maths problem displayed on the screen. There were graphical displays (graphs) and then equations in another panel on the screen. The participant could use a tablet to doodle, make notes or draw to help resolve the problem. The notes were recorded as they were taken and I think the video data, which captured the participant as she used the think aloud strategy and talked through what she was doing.
However at the end, you have an enormous amount of data to analyse and you need to be prepared for that.
