If plans to focus in human-computer interaction at Carnegie Mellon University are in the future, the credit is due to Stuart K. Card.  Dr. Card received his Ph.D. in Psychology from CMU, with an interdisciplinary curriculum comprised of artificial intelligence, psychology and computer science.  Dr. Card's research is paramount to the development of human-computer interaction.  His research on input devices complemented Fitts' Law, a predictive model of time to move a given distance using a mouse.  This research helped computer mice become a commercially viable input device.  With the help of Alan Newell and Tom Moran, Dr. Card researched models of human performance that are used in information systems design.  Some of Dr. Card's influential theories include the Model Human Processor, the GOMS theory of user interaction and information foraging.  Dr. Card is the manager of the User Interface Research group at the Xerox Palo Alto Research Center (PARC).  His work at PARC has resulted in nine commercial products for Xerox.  Dr. Card remains a key pioneer of user interfaces, introducing new paradigms of human-computer interaction through his research.
