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.
