Facial action coding system

Facial action coding with The Observer XTMany researchers code muscle movements to learn more about pain, happiness, or engagement. They use the Facial Action Coding System which provides them with a technique for the reliable coding and analysis of facial movements and expressions.
With The Observer® XT it is possible to manage the whole FACS or parts of it, allowing comprehensive coding when needed. Video and codes can easily be synchronized and The Observer XT offers multiple analysis options, such as reliability analysis.

“The Observer is an excellent tool to code the complexity of facial expressions, their on- and offset, their time course and their changing intensities”  [Dr. Miriam Kunz, Germany]

 

Non-verbal behavior studies

Research has demonstrated that most human communication is non-verbal, and only measurable by means of observations. Methods range from straightforward live observations with a handheld device to elaborate lab studies, and from video analysis with The Observer XT to automatic facial expression recording with FaceReader™. FaceReader is the revolutionary software which automatically analyzes facial expressions: happy, sad, angry, surprised, scared, and disgusted.
