Abstract
ScanEval is an eye tracking software toolkit that records and processes eye movement data in terms of screen regions of interest. Based on these data, the system provides real-time attention assessment measures that can be used dynamically to provide feedback to an application, as well as a variety of summary measures and data capture that can be used for post analysis. This toolkit can be used for a wide variety of purposes including: reactive multi-media or multi-modal systems, training systems incorporating attention assessment, interface design and evaluation, or human factors experimentation. ScanEval is designed as a self-contained program with an application programming interface, for ease of integration with existing applications. It represents a major new enabling technology for commercial systems, in that it will make eye-tracking and visual attention measurement readily available to system developers.
