A mathematical model of local and global attention in natural scene viewing

Experimental and simulated saccade direction and saccade direction change frequency.
Left. Absolute saccade direction. The empirical data demonstrate a strong tendency to saccades towards the left and right directions, and a weaker tendency to perform saccades directed upwards. The generated data captures the tendency to perform horizontal saccades, but not vertical saccades. Right. Change in saccade direction. The generated data demonstrates the tendency to persist in the same direction. The models fail to capture this persistence.
