Abstract

Heat map is an important tool for eye tracking data analysis and visualization. It is very intuitive to express the area watched by the observer, but conventional methods ignore saccade information that express gaze shifts. Based on the conventional method, this paper presents a novel heat map generation method for eye tracking data. Proposed method uses a mixed data structure of fixation points and saccades, and also adds heat map deformation calculation with saccade type data. The proposed method has advantages on indicating gaze transition path while also visualizing gaze region. Related applications will benefit from this work.
