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 (HCI).
My overarching research interest involves
scientifically understanding people's interactions with computers and information, and
improving those interactions through design and engineering.
My specific research topics include:
(i) input techniques (text entry, pointing, touch, gesture, voice, gaze),
(ii) mobile and tabletop user interfaces,
(iii) human performance with computers,
(iv) HCI research and design methods, and
(v) accessible computing for people with disabilities.
My work has received 18 paper awards —
6 best papers and 7 honorable mentions from CHI;
2 best papers from ASSETS;
and 3 best papers 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 September 2012 – May 2015, its
Chief Scientist from May – December 2015, and its
Chief Experience Officer thereafter. I have also worked in other
industry jobs and occasionally serve as an
expert witness on intellectual property matters.
