The child trials were designed to simultaneously evaluate the Affective Tigger and his potential for helping children with their understanding of emotions. From these trials the Affective Tigger was modified, when possible, in accordance with the feedback from the child and parent, until he was `tuned' for the average child. For example, during the first trial, the Affective Tigger was overly happy. After the parent mentioned that he was overly happy, the threshold on the bounce detector was modified to make it less sensitive. This iterative process of design corrections and child trials proved to be an effective technique for determining the proper thresholds for the Affective Tigger's sensory system.
