We detect saccades based on the fixation results, considering the gaps between fixations to be saccades. Note, that this assumption is only true in the absence of smooth pursuit eye movements. Additionally, the fixation detector does not compensate for blinks, which can cause a break in a fixation and thus introduce a false saccade.
