Virtual Reality technologies are evolving at a fast pace. It is important to establish if these novel solutions met the goals they were developed for (i. e., to evaluate if they are effective). These technological-based products, whether based on a conventional PC setup or an immersive virtual reality setup, predominantly rely on the stimulation of the sight. With this, the eye movement analysis appears as an important metric to evaluate technological environments. Through eye movement analysis can establish how persons collect information and what influences their actions and decisions and determine certain preferences or behaviours.
