Peak Velocity Window

The velocity curve must resemble a certain pattern to be regarded as the

velocity of a saccade. In a typical saccade the velocity of the eye

movement increases, reaches a peak and decreases. At first, the

detector assumes this kind of movement to be a saccade. The time

between start and end of movement is called saccade length. Then the

detector searches, if the velocity peak lies within a certain time window

inside of the saccade. If the peak lies outside, the assumed saccade is

discarded. The start and end of the time window is given in % of the

saccade length.

Default values:

Start: 20% of saccade length

End: 80% of saccade length
