Abstract:
Eye movement analysis is gaining popularity as a tool for evaluation of
visual displays and interfaces. However, the existing methods and tools for
analyzing eye movements and scanpaths are limited in terms of the tasks they
can support and effectiveness for large data and data with high variation. We
have performed an extensive empirical evaluation of a broad range of visual
analytics methods used in analysis of geographic movement data. The methods
have been tested for the applicability to eye tracking data and the
capability to extract useful knowledge about users' viewing behaviors. This
allowed us to select the suitable methods and match them to possible analysis
tasks they can support. The paper describes how the methods work in
application to eye tracking data and provides guidelines for method selection
depending on the analysis tasks
