"The Rationalizer system consists of two components - the EmoBracelet and the EmoBowl. The bracelet measures the arousal component of the user’s emotion through a galvanic skin response sensor. This arousal level is rendered as a dynamic light pattern on either the EmoBracelet itself or on the EmoBowl. The higher the arousal level, the more intense the dynamic light pattern becomes: the number of elements increases, the speed increases and the color shifts from a soft yellow, via orange, to a deep red."
