In our previous work the method of fractal analysis was used to evaluate eye movement scanpaths (Belyaev et al., 2013). The assessment procedure was used to evaluate scanpaths fractal dimensions (Higuchi, 1988), which allowed evaluating the structural complexity of eye movements. The aim of the current study was to use the method in order to explore individual differences in eye tracking paths during fixations. Specifically we investigated whether fractal dimensions of scanpaths would change depending on external factors (an image orientation) and on internal factors (individual strategy of eye movements). 24 stimuli were presented: 3 types of images (a landscape, a sea wave image and a fractal image) each of which had 8 orientations relative to the central image point (0º, 45º, 90º,..). 24 participants were tested. The results showed that there were no significant differences in fractal dimension values for different image types and orientations. However, significant fractal dimension differences were revealed within the individuals. So, the method may be used to evaluate characteristics of eye movement scanpaths and to distinguish individuals accurately.
