Initializes fixation detector to Tobii Studio default

Méthodes protégées

Méthode Description
GazeDataReceivedSynchronized ( object sender, GazeDataEventArgs e ) : void

Forwards 2D gaze points to fixation detector. Gaze points are only forwarded if CPU and Eyetracker clocks are synchronized and validity is < 2. If both eyes are valid gaze point coordinates are averaged, if only one eye is valid, only that eye's gaze point is used.
GazeDataReceivedSynchronized ( object sender, GazeDataItem gazePoint ) : void

Forwards 2D gaze points to fixation detector. Gaze points are only forwarded if CPU and Eyetracker clocks are synchronized and validity is < 2. If both eyes are valid gaze point coordinates are averaged, if only one eye is valid, only that eye's gaze point is used.

Private Methods

Méthode Description
getTimestampOffset ( int milliseconds ) : int

Sets the first timestamp to be at time zero, offsets all subsequent timestamps accordingly. Only call this method when SyncManager is Synchronized.
