Judy Kay is Professor of Computer Science at the School of Information Technologies (formerly, Basser Department of Computer Science) at the University of Sydney. She is a principal in the CHAI: Computer Human Adapted Interaction Research Group, leading research in advanced technologies for human computer interaction, supporting personalisation, pervasive and mobile interaction. Her vision is to support a highly personalised way for people to interact with the computers that they carry, those embedded within the environment as well as desktop computers. CHAI researchers are exploring ways to ensure that people can readily make use of these as part of their own personalised augmented memory. We aim to put a personalisation layer over these devices so that each person can make the most effective use of them for key aspects of their lives. Critical to this vision is that the user should always feel a sense of control over the personalisation. She creates new tools for interaction in support of lifelong learning, collaboration and personalised smart services. Examples of exploring novel interfaces for ubiquitous computing include new software for surface computing that enables people to interact at a table, new ways to access files when collaborating at a tabletop and the Keep-in-Touch communication appliance. Her personalisation research has created a framework for building personalised applications which enable the user to scrutinise and control the whole process of personalisation. The core technologies are the Personis user modelling server and Personis-Lite. She has extensive publications , in venues such as the conferences, Pervasive, Computer Human Interaction (CHI), User Modeling (UM, AH, UMAP) and journals, such as IEEE Transactions on Knowledge and Data Engineering, International Journal of Artificial Intelligence in Education, User Modeling and User-Adapted Interaction, Personal and Ubiquitous Computing, Communications of the ACM, Computer Science Education. Invited keynote addresses include: UM'94 User Modeling Conference, Boston, USA; IJCAI'95 International Joint Conference on Artificial Intelligence, Montreal, Canada; ICCE'97, International Conference on Computers in Education, Kuching, Malaysia; ITS'2000, Intelligent Tutoring Systems, Montreal, Canada; AH2006 Adaptive Hypermedia and Adaptive Web-Based Systems, Dublin, Ireland; ITS'2008, Intelligent Tutoring Systems, Montreal, Canada; EC-TEL'2010, European Conference on Technology Enhanced Learning, Barcelona, Spain.
