  • Ability to distinguish any number of fixation and pursuit events within
    a single inter-saccade-period
  • No longer use a maximum amplitude parameter to distinguish pursuits from
    fixations, but use a single velocity threshold instead. The threshold
    is evaluated against a heavily low-pass filtered gaze trajectory, to
    only reflect "smooth" eye movement components (and thereby suppress the
    impact of measurement noise).
  • New parameter noise_factor that influences the adaptive saccade velocity
    threshold. The saccade onset velocity threshold is the median of all
    sub-threshold velocities plus noise_factor times the MAD of these
    velocities. The saccade peak velocity threshold is computed in the same
    fashion, but uses 2x noise_factor. The default value should work for
    noisy data. Reducing this factor can boost saccade detection sensitivity
    for clean data (e.g. Nyström et al., 2010 use the equivalent of a factor
    of 3.0)
