High Speed Event Detection Settings

For High Speed Event Detection the following parameters are

displayed and can be changed:

Min. duration: minimum saccade duration in [ms]. If the Auto option is

checked, the minimum duration varies and is automatically set dependent

on the peak threshold.

Peak velocity threshold: peak velocity threshold in [º/s]

Min. fixation duration: minimum fixation duration in [ms]. All fixations

below the threshold are rejected.

Peak velocity window: The single peak value has to lie in this window.

Start and end is given in % of the saccade length.

For more information see Built-In Event Detector .

If you click on Adjust, the saccades, fixations and blinks will be
