Package: gaze

Nodes for Gaze (Eye Tracking) analysis.

These nodes are for processing of eye-tracker data or other eye movement measures. These typically act on the time series of gaze coordinates, pupil diameter, confidence and so forth, and the data are expected to have a time axis and a space axis.

Nodes in this package:

• Estimate Adaptive Threshold
  Calculate adaptive threshold.

• Extract Gaze Events
  Detect fixations and saccades in continuous gaze data.

• Gaze Screen Coordinate Conversion
  Perform coordinate conversions on gaze data.

• Sanitize Gaze Data
  Clean up gaze data before extracting gaze events.

• Set Gaze Metadata
  Overwrite the screen-related metadata of a gaze stream.
