22 Rothkegel et al. Figure 6 . Mean horizontal distance X$_{MHD}$ ( t ) of gaze position at time t from starting position. (a) Almost all curves show an overshoot of the mean gaze position to the image side opposite to the starting position.

The big white marker on the right side indicates the initial fixation position. Simulated fixations from the gaussian model (bright blue path) remain close to the cur- rent fixation position due to a limited attentional span. The density map model (yellow path) produces longer saccade amplitudes than observed in the experiment and cannot reproduce the typical distribution of saccade amplitudes. The SceneWalk model (pink paths) produces scanpaths that are statistically more similar to the experimental data than the two random-sampling models. The saccadic momentum model shows similar scanpath statistics as the data, as angles and amplitudes are sampled from the data and 0 3 6 9 12 15 18 0 2500 5000 Time [ms] Distance to Starting P osition [°] Star t Left Right Imag T ype Left F ocus Balanced P atter n Right F ocus 0 3 6 9 12 15 18 0 2500 5000 Time [ms] Distance 0 3 6 9 12 15 18 0 2500 5000 Time [ms] Distance (a) (c) (b)
