The Rich Information Potential of Eye Movements for Building Psychological Theory and for Assisting in Human Expression.
Speaker: Anthony Hornof, University of Oregon

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.
