Abstract

The paper proposes a software system for eye-tracking and data analysis during on-screen testing. Proposed system consists of two components: client application that communicates with eye-tracking device and functions for processing and visualization of collected data. Data processing involves mapping raw pairs of coordinates obtained by eye-tracking device in a sequence of regions of interest. Proposed system provides support for three types of visualization: via gaze heatmaps, via gaze flow graphs and via flow of regions of interest. The research has been evaluated by applying the proposed system within an experiment in which 51 undergraduate students took a general knowledge test.
