Abstract:

This talk will present two different uses of eye tracking in human-
computer interaction, first to guide the development of cognitive
models of human visual search, and second for use by children with
severe motor impairments to express themselves creatively.

Cognitive models are computer programs that simulate human
perception, decision-making, memory, and action.  Cognitive modeling
provides a badly-needed science base for predicting the usability of
user interfaces and information appliances.  The models are often
built with a "cognitive architecture" that integrates established
human performance capabilities and limitations into a computational
framework.  This talk will present models of visual search that were
developed using the EPIC (Executive Process-Interactive Control)
cognitive architecture, and guided by eye movement data.  Cognitive
modeling and eye tracking complement each other very well:  The
models offer a unique perspective for interpreting eye movement data,
and the eye tracking provides precise measures for evaluating the models.

Eye tracking also offers a special opportunity for people with severe
motor impairments to communicate with their eyes.  The "EyeDraw"
software enables children with motor impairments to draw pictures
with their eye movements.  It was developed with young collaborators
distributed across the country.  The next major phase of this project
is to collaborate directly with children with motor impairments to
design new eye-controlled software, and to develop software that can
intelligently negotiate a young child's initial interactions with a
gaze-controlled interface.
