FaceReader – Automatically analyze facial expressions

This plug and play software gives you a complete, contact-free view of facial expressions, vital signs, and gaze.

The latest version of FaceReader makes research easier and more efficient. The redesigned, intuitive interface simplifies experiment setup and the enhanced processing power delivers results faster than ever.

Plus, exciting new capabilities let you analyze emotions from voice and detect multiple faces at once. Other new options include measuring engagement, eye gaze, and eating and drinking behaviors.

A complete view of human behavior

FaceReader^TM combines facial expressions, voice, eye gaze, and physiological signals in one intuitive interface. It lets you see how people feel, sound, and react at the same time, giving you a more complete picture of their emotional and behavioral responses. This integrated view helps you connect subtle cues across modalities, revealing patterns that would otherwise remain hidden.

See emotions, reactions, and physiology come together

With synchronized data in one view, you can uncover deeper insights and truly understand human behavior - without switching tools or disrupting natural reactions.

Quick results in any setting

Whether you're a researcher and need validated data analysis of facial expressions, or a UX designer looking for quick insights in emotions, FaceReader provides it within one tool.

Get started right away

FaceReader analyzes and visualizes your emotion data immediately, saving you valuable time.

To work with FaceReader, you only need a webcam - no calibration needed. This also allows you to make unobtrusive observations in any setting.

Validated in research

We compared the results of FaceReader with the intended expressions from the Amsterdam Dynamic Facial Expression Set (ADFES).

Our findings? FaceReader has an average accuracy of 99% in measuring the six basic expressions. Read more in our white paper on FaceReader's methodology or check out other validation studies on our resources page!

Most cited

Moreover, FaceReader is by far the most cited facial expression recognition software, with references in over 2,000 peer-reviewed publications.

Detailed facial expressions

FaceReader offers the functionality to measure Action Units - muscle groups in the face that are responsible for facial expressions.

This unique feature in FaceReader distinguishes the intensity of the active muscles at the left and the right side of the face separately.

Create custom expressions

You can also use Action Units and other variables to design your own algorithms. This allows you to analyze states such as workload, pain, or embarrassment.

Detect emotions in voice

Voice analysis in FaceReader 10 helps you study emotional states in more detail, even before they show on someone's face or when someone tries to mask their feelings.

Better emotion data

By combining facial expressions and voice analysis, you can see if vocal tone matches expressions, how emotions differ in stress or mental health conditions, and even improve AI emotion detection.

The result is stronger, more reliable data for your study.

Analyze up to 8 faces in a single video

You can now track facial expressions of multiple people in one video, giving you a better understand of relationship between emotional states and social interactions or group dynamics.

Insights into interactions

You can study how people's behaviors influence each other or how moods shift during a session. Or analyse an online meeting of conference call.

In the new version of FaceReader, you can analyze facial expressions of up to 8 people in one video. Scale up your research.

Webcam-based eye-tracking

FaceReader 10 lets any USB webcam track eye movements and gaze in real time.

Get clear evidence on where people focus to fine tune products, packaging, and instructions
Plug and play: Install the software, connect the webcam, and start gathering insights in minutes

Measure vital signs - no sensors needed

Measure heart rate, heart rate variability, and breathing rate directly from the face. No extra equipment needed, no discomfort for your participants.

Include physiology to strengthen your data

This lets you observe signs of fatigue, tension, or excitement right when they happen - and see how they match with facial expressions.
