|-
| Minimal Saccade Duration        
| Defines the minimal saccade duration threshold (in ms.) for the velocity-based detection algorithm. If a saccade candidate shorter than the threshold, it's discarded after completion. Note that, the element can still be triggered at the start and peak velocity of the discarded saccades, when the triggering mode is not 'On the saccade end'. If you do not want to apply the minimal duration threshold, set the zero value.        
| {s:atNormal}        
| Double        
|  
|-
| Maximal Saccade Duration        
| Defines the maximal duration threshold (in ms.) for the velocity-based detection algorithm. If a candidate saccade shorter than the threshold, it's discarded after completion. Note that, the element can still be triggered at the start and peak velocity of the discarded saccades, when the triggering mode is not 'On the saccade end'. If you do not want to apply the maximal duration threshold, set the zero value.

'''HeatMap Analyzer Element''' analyzes eye tracking or mouse movements and builds heatmap of fixations over duration of the parent event. The heatmap can be monitored on a real-time plot and later exported into a bitmap or numerical data file. The elements also allows recording a video of heatmap development over a time.
