Several add-on modules expand FaceReader software to meet your research needs. For example, if you are looking for an easy way to analyze and report your results in detail, the Project Analysis Module will help you with that. Moreover, the Action Unit Module offers you automatic analysis of 20 Action Units. The third module we provide enables you to estimate the heart rates and heart rate variability of the test participants.
Project Analysis Module
For advanced analysis of facial expression data, the Project Analysis Module should be part of your software. You can easily evaluate stimuli, such as a commercial or an image, by comparing male participants to female participants, for example.
The Project Analysis Module includes the Stimulus Presentation Tool. By designing a test, this tool automatically shows the test participants the stimuli while FaceReader accurately analyzes the participant’s face.
Action Unit Module
Action Unit classification adds valuable information to facial expressions recorded by FaceReader. This add-on module allows for the automatic analysis of a selection of 20 common Action Units, such as raising of cheeks, wrinkling of nose, dimpling, and lip tightening.
Design your own algorithms for analysis of workload, fake vs genuine smiles, pain, embarrassment, and more by combining variables such as basic facial expressions, Action Units, and heart rate. This way, you can create your own custom expressions.
Remote Photoplethysmography (RPPG)
With this module, based on patented technology, you can analyze heart rate and heart rate variability of the test participant without additional hardware, using the FaceReader camera. The Photoplethysmography (PPG) technique measures the small changes in color caused by changes in blood volume under the skin epidermis. Determining the subject’s heart rate can be particularly useful as an additional indicator of arousal for subjects or situations where there is little variation in facial expressions.
Consumption Behavior Module
For the analysis of behavior that is related to eating and talking, the consumption behavior module is available on an experimental basis in FaceReader 8. This add-on module allows you to analyze the following behaviors:
- Taking a bite (or taking a sip)
- Chew motion
