Given an input stimulus and a specific focus of attention (FOA) model, the general aim of the project is to investigate the presence of characteristic patterns in the corresponding simulated scanpaths. Human scanpaths can be roughly segmented in three different types of movements: fixations, smooth pursuits and saccades. During fixations, small oscillations of the FOA, dubbed as microsaccades, take place in a small area surrounding the current point of interest. Then, each microsaccade can be eventually associated with the object/visual pattern the FOA is spanning in the selected area. The main idea is then to describe simulated microsaccades in the frequency domain and to verify if different frequency contents codify different objects/visual patterns. This analysis could also be extended to smooth pursuits, filtering out the smooth movement of the FOA while retaining its micromovements.
