Non intrusive

Non-intrusive research method


Avoid intrusive research methods that introduce bias into reactions. A face video recorded from a standard webcam is all you need. Live visualize, analyze, aggregate and export all raw data and metrics.

Post analyze facial expressions

Have a big library of existing recordings? Batch upload all videos to iMotions and quickly extract all facial expression data, analyze & aggregate it, and export results directly.

visualize and export

Live visualize, aggregate & export raw data


Live visualize all emotion and facial channels synchronized with the stimuli on a timeline. Segment and aggregate across participants and export all raw data to import it into any statistical program for further analysis.

Affectiva facial expression

The Affectiva engine, called AFFDEX, identifies the face and then locates the main feature points on the face, such as eyes and mouth. Then, it assesses movement, shape and texture of the face at a pixel level. Main outputs are:

  • 7 Basic Emotions: Joy, Anger, Surprise, Fear, Contempt, Sadness, Disgust
  • Valence: Positive, Negative & Neutral Sentiments
  • Emotion Channels: Smile, Brow Furrow, Brow Raise, Lip Corner Depressor (Frown), Inner Brow Raise, Eye Closure, Nose Wrinkle, Upper Lip Raise, Lip Suck, Lip Pucker, Lip Press, Mouth Open, Lip Corner Depressor, Chin Raise, Smirk.
  • 33 facial landmarks: (x,y coordinates), so-called “Feature Points”
  • Head Orientation: Pitch, yaw and roll angels in a 3D space
  • Interocular Distance: Distance between the two outer eye corners
  • Engagement: Emotional Engagement
