Output

FaceReader displays a number of windows with graphical and tabular output.

Important Notes

• Not all visualization options may be available by default. If you do not see some of the options described in this Quick Start Guide, choose File > Settings > Analysis Options and select all options.
• If you selected the Baby Face model, not all output is available. See the FaceReader Help for more information.

Output Procedure

1. Click on one of the buttons in the Analysis Visualization window to show, for example, the key points in the face or the Facial States.
2. To switch windows, click on the Select window button in the upper-right corner of one of the windows and make your selection. See Analysis Windows below for a short description of the options.
3. To zoom, or to copy or save graphs, click on one of the icons on the window toolbar.
4. To show more windows, click on the Split/Unsplit buttons in the upper-right corner of one of the windows.

Tip If you notice the test participant shows a bias towards some facial expressions, use one of the calibration methods to correct for that. See Analyze Facial Expressions/Calibrate FaceReader in the FaceReader Help for details.

Analysis Windows

You can choose between:

• Face Analysis
  • Action Unit Intensity – Available with the Action Unit Module.
  • Circumplex Model of Affect – A chart in which emotions are described in a two-dimensional circular space, containing arousal on the vertical axis and valence on the horizontal axis.
  • Expression Intensity – A chart that displays which of the facial expressions show up in the face.
  • Expression Line Chart – A line chart with the facial expression intensities over time.
  • Expression Summary – A pie chart with the distribution of the facial expressions.
  • Facial States – Whether, for example, mouth or eyes are open or closed.
  • Gaze Angles Line Chart – Horizontal and Vertical gaze angle on a time line.
  • Head Orientation Line Chart – The head orientation on a time line (Pitch, Yaw and Roll).
  • Head Position Line Chart – Horizontal, Vertical and Depth position on a time line.
  • Subject Characteristics – With, for example, the estimated age and gender.
  • Valence and Arousal Line Chart – Valence indicates whether the emotional status of the test participant is positive or negative. Arousal is based on the activation of the 20 Actions Units in FaceReader.
• Consumption Behavior (available with the Consumption Behavior Module)
• Vital Signs (available with the Vital Signs Module)
• Voice Analysis (available with the Voice Analysis Module)
• Analysis Visualization – Click on a button on the left to view how FaceReader analyzes the face.
• Custom Expression Table – Available with the Action Unit Module.
• Custom Expression Line Chart – Available with the Action Unit Module.
• Stimulus View
• Timeline – An overview of the facial expressions, and facial states on a timeline.

See FaceReader's Output in the FaceReader Help for a full description of the analysis windows.

Export

To export your data, choose File > Export. Choose to export the results of the analysis, participant, or entire project. You have the following options:

• State log – A text file or Excel file with the dominant facial expressions as states over time.
• Detailed log – A text file or Excel file with the intensities of all facial expressions over time. To save extra options, like facial states, global gaze direction, valence and arousal values to the log file, select these options in the Data Export tab of the Settings window (File > Settings). Optionally, adjust the sample rate of the export file and select whether to include headers.
• Heart beat log – A text file or Excel file with the inter-beat interval data (the time intervals between individual heart beats).
• The Observer XT log – Choose this option if you want to import the analysis results in the annotation software The Observer® XT for further analysis. The Observer XT log exported from FaceReader can be imported into The Observer XT to display facial expressions on the time line. An example project called 'Child FaceReader' demonstrates this: a 3-year old boy is observed playing an online game, his face filmed with a webcam while the screen is captured with the Noldus screen capture device. The facial expressions are shown as states on the timeline in The Observer XT.

Tip It is also possible to send the analysis results directly during the FaceReader analysis to The Observer XT, using the Noldus network communication program N-Linx. See FaceReader with The Observer XT in the FaceReader Help for details.
