Title:

    iComp: a tool for scanpath visualization and comparison

Presenter(s)/Author(s):



Abstract:


    To evaluate differences across viewers’ visual attentional patterns, scanpath comparison has recently gained popularity in eye tracking studies, supplementing traditional objective (performance) and subjective measures (e.g., heat maps or [retrospective] talk-aloud). We introduce iComp, an open-source visualization tool that implements quantitative scanpath comparison in loci and sequence. iComp can be used to objectively compare the attentional qualities of synthetic images.
