Modules

You can extend the base functionality of FaceReader with modules. Your license determines which modules you can use. For Baby FaceReader only the Vital Signs Module is available. You can check what modules have been enabled on your license. From the Help menu select About and in the window that opens under Modules click Enabled Modules.

Action Unit Module

With the Action Unit Module you can analyze the intensity of a number of Action Units from the Facial Action Coding System (FACS). FaceReader can analyze 20 Action Units, that are most common in facial expressions. With the Action Unit Module you can also define your own expressions (Custom Expressions). You can, for instance, combine 'Happy' and 'Arousal' to assess what commercial makes your test participants happily aroused. Interest, Boredom and Confusion which were called Affective Attitudes in FaceReader 7.1, are now available as Custom Expressions.

See The Action Unit Module

Vital Signs Module

With the Vital Signs Module you can analyze the heart rate and heart rate variability of the test participant by means of remote photoplethysmography. In FaceReader 10 you can also analyze the participant's respiratory (breathing) rate.

See The Vital Signs Module

Voice Analysis Module

With the Voice Analysis Module FaceReader can recognize emotions in the voice (Neutral, Happy, Sad and Angry) and Valence and Arousal. In addition, the software can assess the Loudness and Speech rate.

Advanced Research Module

This module allows you to analyze multiple faces in a video. With this module and the Stimulus Presentation Tool you can also track the gaze of the test participant to assess what he/she is looking at when you present stimuli.

See The Advanced Research Module and Stimulus Presentation Tool

Consumption Behavior Module

With the Consumption Behavior Module you can determine whether your test participants show chewing behavior, take a bite when testing a food item or take a sip when testing drinks. Bites and sips are called 'intake events' in FaceReader.
