During the upper limb scenario of the first iteration of pilot 1 of the SUN project, CERTH presented an emotion recognition component based on the EmotiBit smart wrist-worn sensor. By using photoplethysmograph, electrodermal activity and temperature data the component was able to predict the emotional state of patients while they were performing rehabilitation activities.
