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—studying and shaping it
to create better user experiences.
My specific research topics include
human performance measurement and modeling,
HCI research and design methods,
mobile computing, and
I pursue a vision of Ability-Based Design,
where the human abilities required to operate a technology in a given context are questioned, and
systems are made operable by or adaptable to alternative abilities.
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.
