Gaze is more than just a point: Rethinking visual attention analysis using peripheral vision-based gaze mapping

Abstract

Figure 1: Workflow of the four major steps for the calculation of a peripheral vision-based attention measure, the visual attention index (VAI). ( 1) The given multi-object handling task defines the objects of interest (OOIs). ( 2) Mobile eye-tracking data is recorded and the vision areas are quantified. (3) Object detection is conducted using Mask R-CNN and the distances of the gaze center to each OOI is calculated. (4) The VAI, which considers both spatial and temporal information, is computed for each task and visualized using a radar graph for attention analysis.
