My interest is in HCI, human interface technology, and the design of novel sensing and interaction techniques for anything from smart devices to AR/VR. I am particularly interested in eye movement and recently won an ERC Advanced Grant to investigate new foundations in for gaze and gestural interaction. Over the last ten years, my group has contributed major innovations on gaze in HCI, notably on smooth pursuit interfaces and techniques, gaze-supported manual input, and eye-head interaction. We have recently focussed on interaction in 3D but I maintain long-standing interests in ubiquitous computing, cross-device interaction and interfaces that blend the digital and the virtual.
