This topic relates to the integration of our eye movements and gaze within the context of the computer user interface. Eye-tracking technology has had many use cases since the 80s with regards to improving the computer’s accessibility by enabling novel ways of computer control, understanding user behaviour through study of visual attention, and utilising gaze information as a rich source of context information for implicit and adaptive user interfaces. Our team works by designing novel eye-based interaction concepts, implementing interactive systems that integrate eye-tracking information, and conducting eye-tracking user studies.
Eye movements have a long history of social impact, particularly for advances user interfaces for people with disabilities to offer control methods that do not rely primarily on hand-based inputs. There is also a high potential of the method for general interface navigation, with a range of typical devices such as tablets, desktop PCs, and extended reality (XR) headsets and glasses adopting eye-tracking sensors. Through these devices, novel behavioural insights can be gained given that eye movements indicate cognitive and motor processes of the user, which can be leveraged to improve the understanding of behavioural patterns, intent, and attention.
