Sleep Elf: A Pillow Robot Accompanies Child to Sleep Better

Child sleep problem is one of the major pain points for parents, which usually last from infancy to school-age. Child sleep problem not only affects child's health and development but also causes depression and anxiety in parents. To address this, we designed a child sleep companion robot to help child fall asleep quickly and encourage child to sleep without parent. We conducted a detailed product interaction design, and a prototype was built and tested to achieve a more intuitive human robot interaction.
