Аннотация:The aim of our investigation was to analyze characteristics of return sweep saccades (RSS) which voluntary were executed on return sweeps from the end of one line to the beginning of the next during reading. 12 texts were constructed consisting of 60-64 words organizing in 6 lines, each subtended 15 degree of visual angle. 14 participants were tested. Their gaze positions during reading were recorded with SMI Hi-Speed technique. Saccade characteristics were analyzed including the distribution of saccade amplitudes, peak velocities and trajectory curvatures. The significant individual differences were revealed in all analyzed values. Using the RSS characteristics the dynamic model of the eye was developed which predicted approximate estimates of eye rotational dynamics. According to the model the equation was proposed linking the forces rotating the eye with the trajectory of eye movements. Our results may allow a better understanding of the eye dynamics in reading particularly in individual strategies of eye movements when performing RS saccades.
