My field is human-computer interaction (HCI).
My research seeks to scientifically understand people's interactions with computers and information,
and to improve those interactions through design and engineering,
particularly for people with disabilities.
Interaction is my major phenomena of interest—analyzing it, modeling it, and designing it
to create better user experiences. I therefore both study and build.
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.
A vision I am currently pursuing is
a design approach in which the human abilities required to operate a technology
in a given context are questioned, and systems are made operable by and adaptable to
My work has received 19 paper awards, including
7 best papers and 7 honorable mentions from the
ACM CHI conference.
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 system.
