Eamonn O’Neill is Professor and Head of the Department of Computer Science at the University of Bath. His research has the overall goal of developing an applied science of human-computer interaction (HCI), developing a sound theoretical footing for HCI and deriving design principles for the development of human-computer systems that are theoretically well-founded, empirically tested and operationalised for people’s use. The main focus of Eamonn’s research is in mobile and pervasive computing systems, i.e. computing and communications devices, applications and resources distributed in our environment and carried in our pockets and on our clothing. The research covers the spectrum of cognitive, social and technological problems and opportunities that these systems bring. Primary application areas in Eamonn’s reserach include cultural heritage visitor experiences, 3D interaction, and augumented and virtual reality.
