Rob Jacobs, currenly at Tufts University, was early on interested in gaze based interaction. Jacobs have a long list of both honors, publications and presentations in the HCI field. Being the founder of the "Midas Touch" analogy and many other fundamental aspects of gaze interaction the guy clearly deserves an introduction.
From his homepage
"Robert Jacob is a Professor of Computer Science at Tufts University, where his research interests are new interaction media and techniques and user interface software. He is currently also a visiting professor at the Universite Paris-Sud, and he was a visiting professor at the MIT Media Laboratory, in the Tangible Media Group, and continues collaboration with that group. Before coming to Tufts, he was in the Human-Computer Interaction Lab at the Naval Research Laboratory. He received his Ph.D. from Johns Hopkins University, and he is a member of the editorial board of Human-Computer Interaction and the ACM Transactions on Computer-Human Interaction. He was Papers Co-Chair of the CHI 2001 conference, Co-Chair of UIST 2007, and Vice-President of ACM SIGCHI. He was elected to the ACM CHI Academy in 2007, an honorary group of people who have made extensive contributions to the study of HCI and have led the shaping of the field."
