FaceReader: Project Analysis Module

The Project Analysis Module can be used for advanced analysis and reporting. With this module, you quickly gain insight into the effects of different stimuli. With the new version of FaceReader, you can now use images as a source of a stimulus as well!

Version 7 allows you to compare responses to different video stimuli in one view, offering faster insights into the effects of stimuli.

Stimulus Presentation Tool

Add the stimuli of your choice – you can easily add videos, with or without sound, or images, and simply use the marker function to code and select events such as ‘start commercial’ or ‘distraction’. The Stimulus Presentation Tool presents the stimulus movie(s) or images to the test participant in a fixed or random order, while at the same time FaceReader is recording the facial expressions. Of course in perfect sync! You can either use the computer where FaceReader is running, or a separate, connected computer to show the stimuli.

  • Event Markers - specify Event Markers, such as when the test participant is distracted, eating, talking etc.
  • Stimuli - specify stimuli with fixed duration. The stimulus has a fixed duration you can specify. And, the stimuli can be a video, for example a commercial. In this case, you can specify the start time of the stimulus within the video file.

The start of a Stimulus or the Start/Stop of an Event is triggered by a key (a letter or number of your choice). For an easy reference, all markers and stimuli are visualized in the Timeline. 

Independent variables

Selections of participants can easily be made automatically or manually, for example, by selecting all female test participants and comparing their responses to different commercials.  You can also add independent variables such as educational level or previous knowledge level, which allows you to make groups (female with high education level) and compare results between the groups you have created.


The Project Analysis Module offers a number of different analysis and reports:

  • Temporal Analysis - this type of analysis is based on a group response toward a single stimulus. The average response of the group can be viewed side-by-side with the stimulus video, the participant videos and line-charts of the absolute and relative average expression, arousal and valence. The results can also be presented as a pie chart. When the stimulus includes audio, this is also audible when reviewing your results.
  • Numerical Analysis - averages and standard deviations of the responses to stimuli and event markers can be viewed in tables, bar charts, and box-plots. All graphs can be saved as a picture for presentation purposes.

Visual presentation of your data

The Project Analysis Module can create multiple visual presentations of your data, including:

  • An individual line graph shows the intensity of the recorded emotions and can be displayed in sync with the video of the test participant and the stimulus, giving you a complete overview. 
  • When working with multiple test participants, a summary line graph can be displayed and synchronized with the stimulus providing a solid impression of the overall responses. 
  • A pie chart which shows a summary of results of multiple test participants based on your own (marker) selection. Choose a pie chart of combined line graphs, whatever provides you with the best overview. 
  • Box plots per emotion of the results of all test participants per stimulus are a real visual aid in determining which emotion prevailed on which stimulus. 
  • All graphs can be saved as a picture for presentation purposes. Output (log files) can be exported to a program of your choice, such as Excel, SPSS or The Observer XT.
