First a gaze pattern, i.e. the curve formed by joining all the points of fixation in consecutive order, is generated. The number of times that the curve crosses over itself is the total crossing number. In two different experiments free eye movements were measured during viewing of natural scenes and the performance of a specific visual task requiring an eye scan through a randomly positioned set of items.
