Detection of Fixations in Eye-Tracking Data
Description
Functions for detecting eye fixations in raw eye-tracking
data. The detection is done using a velocity-based algorithm for
saccade detection proposed by Ralf Engbert and Reinhold Kliegl in
2003. The algorithm labels segments as saccades when the velocity of
the eye movement exceeds a certain threshold. Anything between two
saccades is considered a fixation. Thus the algorithm is not
appropriate for data containing episodes of smooth pursuit eye
movements.
