I am an Associate Professor in the
and an Adjunct Associate Professor in the
Department of Computer Science & Engineering
University of Washington.
I chair the
Master of Human-Computer Interaction & Design
Mobile & Accessible Design Lab.
I am a founding member of the DUB Group.
My field is Human-Computer Interaction.
I invent, design, and build new interactive technologies,
formally study people's interactions with technology.
My research interests are:
- input techniques (text entry, pointing, touch, gesture, voice, gaze);
- mobile and tabletop user interfaces;
- human performance with computers;
- HCI research and design methods; and
- accessible computing for people with disabilities.
My work has been honored with 18 paper awards —
6 winners and 7 honorable mentions from CHI;
2 winners from ASSETS;
and 3 winners elsewhere.
Some of my notable projects are
the $-family gesture recognizers,
the end-user elicitation design method,
the Slide Rule design for accessible touchscreen gestures,
ARTool for nonparametric factorial statistical analyses,
and the EdgeWrite text entry method.
I am currently developing
a design approach in which the human abilities required to operate a technology are questioned,
and systems are made operable by and adaptable to alternative abilities.
My Ph.D. students
come primarily from UW Ph.D. programs in
information science and
I am also an entrepreneur, having co-founded
AnswerDash, a company that provides context-sensitive help
to websites. I was AnswerDash's venture-backed C.E.O. from 2012-2015 and its Chief Scientist since
May 2015. I have also worked in other industry jobs and
occasionally serve as an expert witness on intellectual property matters.
