– Play Button : Plays the current data file by advancing the current data point by 1. Once the last data point is
reached, DA starts playback over at the first data point.
– Rewind Button : Stops playback and sets the current data point to the first data point.
– Stop Button : Stops playback and the current data point remains unchanged so the user can resume playback from
the stopped position.
– Play Speed Slider : Adjusts the play speed for playback.
– Frame Number Edit Box/Spin : Displays the current movie frame. The Frame Number spin control allows the user
to navigate through the movie frame by frame.
– Data Point # Edit Box/Spin : Displays the current data point. The Data Point spin control allows the user to
navigate through the data points point by point.
– Data Time Edit Box : Displays the Total Time for the current data point. The user can change the time to navigate
through the data points. DA automatically set the current data point to the data point that has a Total Time

2.2 The C ontrol s window > Signal Tab

Figure 2. Controls W indow > Signal Tab

– Signal Gain Slider : Sets the gain for the x position and y position plots in the Time Plot window. The gain is a y –
axis scale factor (multiplier) that allows the user t o change the y -axis viewing resolution.
– Velocity Gain Slider : Sets the gain for the x velocity, y velocity, and the velocity magnitude plots in the Time Plot
window. The gain is a y -axis scale factor (multiplier) that allows the u ser to change the y -axis viewing resolution.
– Time Resolution Slider : Sets the time resolution for all plots in the Time Plot window. The time resolution is an x –
axis scale factor (multiplier) that allows the user to change the x -axis viewing resolution.
– Smoothing Slider : Sets the Kernel size for the selected Smoothing Filter . The formula used to calculate the Kernel
is: Kernel = (2 * SmoothingPos) + 1. No smoothing occurs when the Smoothing slider position is set to 0 creating a
Kernel value of 1. Larger Kernel values produce more smoothing than smaller Kernel values.
– Aspect Ratio Gain Slider : Sets the gain for the pupil aspect ratio plot in the Time Plot window. The gain is a y-axis
scale factor (multiplier) that allows the user to change the y -axis viewing resolution.
– Torsion Gain Slider : Sets the gain for the torsion plot in the Time Plot window. The gain is a y -axis scale factor
(multiplier) that all ows the user to change the y -axis viewing resolution. Torsion does not work.

– Pupil Width Gain Slider
The Pupil Width Gain slider sets the gain for the pupil width plot in the Time Plot window. The gain is a y -axis scale
factor (multiplier) that allows th e user to change the y -axis viewing resolution.
– Smoothing Filer Drop List : Sets the current Smoothing Filter for smoothing the data. The current, available filters
the user can select from are Uniform and Gaussian. The user can change the amount of smoothing by adjusting
the Smoothing slider.
– Units Drop List: Sets the current units for the Fixation/Saccade Algorithm. When the algorithm is Velocity
Threshold, the units change for the Saccade Threshold slider. When the algorithm is Dispersion Centroid, the units
change for the Max Dispersion edit box. The current, available units the user can select from are normalized,
degrees, and radians. The degrees and radians options are only available for data fil es in which the screen width,
height, and distance have been set using the geometry setup in ViewPoint. Please make sure the geometry setting
are setup correctly if the degrees or radians units are used.

2.2.1 Fixation / Saccade Algorithm s
There are two algorithms available to identify fixations and saccades.

1. Velocity Threshold

The Velocity Threshold algorithm finds fixations and saccades by identifying the saccades by finding total
velocities that are greater than the saccade threshold. Anything not considered a saccade is considered a
fixation. Changing the saccade threshold changes the number of fixations and saccades identified. The user
can change the saccade threshold by adjusting the Saccade Threshold slider. The saccade threshold value is
shown to the right of the slider in the Saccade Threshold edit box. The units o f the saccade threshold are
indicated by the selection made in the Units drop list.

2. Dispersion Centroid

The Dispersion Centroid algorithm finds fixations and saccades by identifying the fixations by using a weighted
position that allows for the human eye to first land close to the object of interest and then for micro saccades

Arrington Research

Page 8 of 19
to adjust the eye to the object that we want to fixate. The fixations in this case would only consist of those
data points that follow the adjustments made after the eyes landin g position.

Falkmer, T., et al., Fixation identification in Centroid versus Start -point modes
eye tracking data. Perceptual and Motor Skills., 2008(106): p. 710 -724.

Anything not considered a fixation is considered a saccade. Changing the max dispersion and min duration
changes the number of fixations and saccades identified. The user can change the max dispersion and min
duration by directly editing their values in the edit boxes. The units of the max dispersion are indicated by the
selection made in the Units drop list. In order for changes of max dispersion and min duration to take affect,
the user must press the Update button. Because the post processing of the algorithm can take a while
depending in the input values, a cancel/status dialog is sho w after pressing the Update button. The user can
cancel the update at anytime without affecting the current fixations and saccades. Below is the Cancel Dialog.

2.3 Controls W indow > 2D Plot Tab

Figure 3. Controls W indow > Play Tab

– Schematic View Check Box : Toggles the schematic view in the 2D Plot window. In schematic view, the 2D Plot
window draws a circle around the mean data point for the current fixation event. The area of the circle is proportional
to the fixation total time. Schematic view is only available for images, not movies.
– Show Direction Check Box : Toggles the show direction state in the 2D Plot window. In show direction mode, arrows
are used to indicate direction for both saccade and fixation lines. When the show direction mode is not used, th e
saccade and fixation lines are shown without direction being indicated. Show direction mode is only available for
images, not movies.
– Show Images Check Box : Toggles the show images state when displaying images in the 2D Plot window. In show
images mode, the 2D Plot window displays the image associated with the current data point. If there is no associated
image the 2D Plot window displays either a blank window or an image that the user manually loaded. Show images
mode is onl y available for images, not movies.
– Show Fixation Time Check Box : Toggles the show fixation time state when displaying fixations in the 2D Plot window.
In show fixation time mode, the 2D Plot window displays the fixation t otal time at the mean data point for each
respective fixation event. Show fixation time mode is only available for images, not movies.

– Show Data Markers Check Box : Toggles the show data markers state in the 2D Plot window. In show data markers
mode, the 2D Plot window displays data markers at their respective x/y positions. Show data markers mode only
affects drawing in the 2D Plot window and does not affect drawing in the Events window and the Time Plot window.
– Show EyeA/B Gaze Point Check Box : Toggles display of the g aze point as calculated by the DataAnalysis Program.
– Maintain Aspect Ratio Check Box : Toggles the maintain aspect ratio state. In maintain aspect ratio state, the 2D Plot
window is kept at the proper aspect ratio for both movies and images. Anytime the 2D Plot window size changes, the
software automatically adjusts the window size to maintain the aspect ratio of 4:3 (w:h).
– Circle Radius Slider : Sets the circle size when drawing circles in the 2D Plot window. The circles that are directly
affected by this s lider are fixations in schematic view and gaze points in movie playback mode.
– Display Drop List : The Display drop list gives options for how the data points are drawn in the 2D Plot window relative
to time.

All Data – This option forces the 2D Plot window to display graphics for all the data points at once.

From Data Start to Current Data Time – This option forces the 2D Plot window to display graphics from the
first data point to the current data point.

From Previous Image to Current Data Time – This op tion forces the 2D Plot window to display graphics from
the previous image to the current data point.

2.6 File Menu Items
Figure 6. File Menu

– File_DataFile : Loads a data file. Selecting this menu option prompts the user with a file selection dialog box.
Once the user selects the data file, the application loads the data file. The data file format is discussed in the
ViewPoint manual under the Data Collection chapter. The data file indicates whether or not the application
should load a movie file or an image file. After loading the data file, the data is processed according to the
settings, then the data is displayed in the Events window, Time Plot window, and either the movie or images
are displayed in the 2D Plot window. The user can now analyze the data.
– File_ImageFile : Loads an image file. Selecting this menu option prompts the user with a file selection dialog
box. Once the user selects the image file, the application loads the image file and displays it in the 2D Plot
window.. Loading a new image fi le while a movie file is loaded causes DA to close the current movie file. If
the current data file contains images, loading a new image file does not overwrite any of the images but will
become the current image anytime DA cannot associate the current da ta point with an image from the data
file.
– File_MoveFile : Loads a movie file. Selecting this menu option prompts the user with a file selection dialog
box. Once the user selects the movie file, the application opens the movie file and displays the first frame in
the 2D Plot window.. Loading a movie file causes the application to close any movie file or image file
previously loaded even if those files were specified in the data file.
– File_Settings : Loads the AOI's from the ViewPoint settings file. Select ing the menu option prompts the user
with a file selection dialog box. Once the user selects the settings file, the application loads all the AOI's from
the settings file and overlays them on the 2D Plot window. “Not imp lemented”.
– File_Print : “Not implemented”.
