The document discusses using eye tracking methods to evaluate different types of information graphics and compare their effectiveness. It describes challenges with eye tracking practices and analysis. An eye tracking study was conducted comparing bar, line and spider graphs on tasks of relative comparison across multiple dimensions within and between graphs. The results showed completion times included scanning, decision making and validation. Different scanning strategies also emerged between graph types like more reciprocal scanning for spider graphs versus viewing one bar graph fully before the other. Questions are raised on best practices for eye tracking evaluation methods and representation of results.
