Abstract
We briefly present the notion of a "collaborative interface", an interface
between human and computer based on collaboration between the two, rather
than the master-slave relationship typically found in conventional user
interfaces. As a motivating example of the approach, we describe a drawing
tool with a novel interface that allows for direct manipulation by both
user and system. We then present some recent work on improving text input
to computers under degraded conditions, such as text entry on PDAs or cell
phones or by disabled users, that has been inspired by the collaborative
interfaces idea. Using simple weighted finite-state transducers to model a
"human-centered compression"" method, we can achieve a substantial decrease
in character entry without the task switching overheads of previous
predictive methods.
About the Speaker
Stuart Shieber is Gordon McKay Professor of Computer Science in the
Division of Engineering and Applied Sciences at Harvard University.
Professor Shieber received an AB in applied mathematics summa cum
laude from Harvard College in 1981 and a PhD in computer science from
Stanford University in 1989. Between 1981 and 1989, he was a computer
scientist at the Artificial Intelligence Center at SRI International
and a research fellow at the Center for the Study of Language and
Information at Stanford University. He has been a professor at
Harvard since 1989.
Professor Shieber was awarded a Presidential Young Investigator award
in 1991, and was named a Presidential Faculty Fellow in 1993, one of
only thirty in the country in all areas of science and engineering.
At Harvard, he has been awarded two honorary chairs: the John L. Loeb
Associate Professorship in Natural Sciences in 1993 and the Harvard
College Professorship in 2001. He is the author of numerous books and
articles in computer science. He has been a member of the executive
committee of the Association for Computational Linguistics, the
editorial boards for the journals Computational Linguistics, the
Journal of Artificial Intelligence Research, the Joural of Language
and Computation, and the Journal of Heuristics, and founded and
organized the Computation and Language E-Print Archive until its
superseding by the Computing Research Repository on which he advised.
Professor Shieber holds five patents, and is co-founder of Cartesian
Products, Inc., a high-technology research and development company
based in Cambridge, Massachusetts, providing advanced software
technology to improve worldwide communication and information access.
