Eye tracking gaze visualiser: eye tracker and experimental software independent visualisation of gaze data

Eye tracking research in disciplines such as cognitive psychology requires specific software packages designed for experiments supporting reaction time measurement, blocking and mixing of conditions and item randomisation. Although recording raw eye movement data is possible, its visualisation is difficult regarding the experimental design. The currently used eye tracking software is often built as an all-in-one program that can only visualise the eye tracking data recorded by itself. Therefore, in this paper a software tool is presented that visualises nearly any recorded eye tracking gaze data on the corresponding video independent of the specific software that runs the experiment. Summarised visualisations over randomised item presentations according to experimental conditions can be created. In addition to basic visualisation functionalities, further features such as simple object detection, repetitive pattern exploration and subset selection of subjects are provided.
