Eye movements: A window into hidden expertise
Matt Stainer and Ben Tatler, Active Vision Lab, University of Aberdeen and Ken Scott-Brown, Abertay University
Where experts look reveals the hidden knowledge of their skill. This is because where we look is not random, but under tight strategic control. Because our vision is limited in both space (with only a clear window of vision of about 1-2 degrees visual angle) and time (with on average 2-3 locations explored a second), strategic deployment of gaze is crucial for informing appropriate behavioural interaction with our world. Importantly, we are not always aware of how our eyes sample the world, thus eye movements can be used to gain insight into expertise that the expert themselves might not be aware of. The aim of our workshop is to discuss how studies of gaze behaviour can provide important insights into expertise in activities as diverse as driving, hitting a cricket ball, and searching an x-ray for nodules or a CCTV system for crime. In the second part of the workshop we will demonstrate our mobile eye-tracking system in action. Recent advances in tracking technology have allowed us to take research out of the lab and into more real-world contexts. This flexibility means that we are able to more easily study gaze behaviour in its natural setting and gain further insights into how experts perform their tasks.
This workshop will comprise a short talk about expertise, followed by a participatory demo of our mobile eye tracking kit. It will be of interest to researchers studying professional or expert behaviour. Whilst application of the kit developed by the Active Vision Lab team has previously been applied in psychology, sports science and criminological settings, it may have potential for health services research, e.g. surgery, clinical trials recruitment and a range of delivery of care settings.
Matt Stainer, vision scientist, and Ben Tatler, Chair in Psychology, recently relocated their Active Vision Lab to Aberdeen from the University of Dundee. They are currently leading an ESRC funded project on words and images. Ken Scott-Brown is best known in Psychology for the idea of ‘Comparison Blindness’. Harry Orbach introduced him to Change Blindness, and while working in his lab Ken suggested that the problem of surprising difficulties in perception that became known as change blindness could be accounted for by the notion of a difficulty in the brain making explicit comparisons, rather than due to explanations of sparse coding of objects.
