The growing interest in using eye-movements for human-computer interaction has also increased the need for tools to investigate and analyze the behavior of human eyes. Nowadays, there are many commercial and academic products available for researchers in this field and the quality and accuracy of eye-tracking devices are constantly increasing. Despite the numerous methods developed for analyzing and visualizing gaze paths, however, no universal tools are available yet to accomplish this. To fill in this gap, we developed iComponent – a software product with a highly flexible architecture for easy development of interchangeable plug-in modules to support various eye-tracking devices and experimental software. iComponent has four types of 2D visualizations of gaze data and one type of 1D visualization. The 2D visualizations are superimposed on the stimulus seen by the user during a session. Three of the visualizations are capable of showing several subjects’ gaze paths simultaneously.
