Handled by trained professionals and attentive parents, this augmented reality toy represents an important aid in the therapeutic relationship and sometimes will even reduce pain. The magic characters place the child at the center of care and give him a measure of autonomy which will allow him to better manage the care. A refusal or an opposition and the child can play hide and seek with the clouds in the hospital room. A care that can hurt? Let’s use the fire truck to water the caregivers. And if we are simply afraid of hospitals or its doctor, send the butterfly to scout!
