Nuanced facial expressions and key emotions


iMotions integrates Affectiva’s Affdex technology to gain deeper insight into human emotional reactions via facial expressions. The powerful facial expression algorithm gives you metrics in many different nuanced facial expressions and key emotions.

It automatically identifies 7 Basic Emotions, Valence, Excitement, 15 Facial Expressions, 33 Facial Landmarks, Interocular Distance, and Head Pose (yaw, pitch, roll).

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 previously recorded faces

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.

Vizualize 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.

“We used to have to rely on the moderator to notice how a participant reacts and then infer what their emotions may be. Now we can really rely on the biometric data in order to find out those moments of frustrations or moments of joy.”
Dan Berlin, VP of Experience Research at Mad*Pow
