Facial Expressions as a Modality for Fatigue detection in Robot based Rehabilitation

Considerable amount of research is being carried out in robot based rehabilitation techniques. One of the main focus when building a smart rehabilitation system is its ability to adapt based on the user experience. In this poster we attempt to build such a smart rehabilitation system that recognizes the strain/ negative emotions from the participants facial expression and adjusts its force exerted. The accuracy of the system to recognize the facial expression is assessed and the accuracy of the system as a whole is estimated through user surveys.
