Advanced Human Affect Visualization

Affective Computing researches use to be focused in the automatic extraction of human emotions and in increasing the success rates in the emotion recognition task. However, there is a lack of automatic tools that intuitively visualize the users´ emotional information. In this paper, the development of a novel tool that allows the visualization of contents, user emotions and gaze at a glance is presented. The tool, called Emotracker, is based on the combination of eye tracking and facial emotional recognition technologies, and offers a wide range of visualization options, including emotional saccade maps and emotional heat maps. The simultaneous consideration of gaze and emotion opens the door to the evaluation of user engagement in a wide range of applications.
