    Facereader 9 Reliability Performance
  • Unobtrusive observations

    As FaceReader only requires a webcam and the easy-to-use software needs no calibration, emotions of test participants are measured unobtrusively.

  • Detailed facial expressions with Action Units

    Action Units are 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. A valuable addition to your facial expression analysis.

  • Create custom expressions

    You can design your own algorithms for analysis of states like workload, pain, embarrassment, and infinitely more. To create custom expressions, you can combine variables such as facial expressions, Action Units, and heart rate.

  • No bias

    The primary reactions of test subjects are recorded, without any bias. Person-specific biases can be calibrated automatically. Read more in our article on ethnicity from the Measuring Behavior 2022 proceedings.

  • Many applications
