As electronic commerce continues to permeate every aspect of our society, a significant segment of the population is being marginalized due to issues of accessibility. This is commonly referred to as the “Digital Divide” [4] Social policy initiatives are attempting to increase accessibility through infrastructure enhancements and increased public points of presence. While this is helpful, it does little to address accessibility issues for persons who are functionally illiterate or cognitively impaired. Computerized systems will remain inaccessible to this population until the complexity of interacting with these systems is significantly reduced. The Knowledge-Acquiring Layered Infrastructure (KALI) project at Dalhousie University is attempting to reduce interaction complexity for this population through domain-specific personalization techniques that customize end-user interactions with computerized systems based on the abilities, preferences, and needs of individual end-users.
