GazeDataHandler that detects fixations. GazeDataReceived method must be subscribed to gaze data events for fixations to be detected. Fixation start, update and end events can be subscribed to through the FixationDetector property. FixDetector written by Oleg Špakov at the University of Tampere in Tampere, Finland. http://www.sis.uta.fi/~csolsp/projects.php Documentation available through download link above.
