title = "Chaotic nature of eye movement signal",
abstract = "The eye movement analysis undertaken in many research is conducted to better understand the biology of the brain and oculomotor system functioning. The studies presented in this paper considered eye movement signal as an output of a nonlinear dynamic system and are concentrated on determining the chaotic behaviour existence. The system nature was examined during a fixation, one of key components of eye movement signal, taking its vertical velocity into account. The results were compared with those obtained in the case of the horizontal direction. This comparison showed that both variables provide the similar representation of the underlying dynamics. In both cases, the analysis revealed the chaotic nature of eye movement for the first 200 ms, just after a stimulus position change. Subsequently, the signal characteristic tended to be the convergent one, however, in some cases, depending on a part of the fixation duration the chaotic behaviour was still observable.",
