Tool for creating eye-aware applications that adapt to changes in user behavior

Abstract

A development tool is described that can be in used to create eye-aware software applications that adapt in real-time to changes in a user's natural eye-movement behaviors and intentions. The research involved in developing this tool focuses on identifying patterns of eye-movement that describe three behaviors: Knowledgeable Movement, Searching, and Prolonged Searching. In the process of doing the research, two important features of eye-movement patterns were discovered - Revisits and Significant Fixations. Revisits and Significant Fixations complement the recognition of saccades, fixations, and blinks, and make easier the recognition of high-level patterns in users' natural eye-movements.
