DenTeach: A Device for Fostering Children's Good Tooth-brushing Habits

In this paper we present DenTeach, a smart brush with a doll-shaped tangible device. We designed and to foster children's good tooth brushing habits by explicitly showing the effect of their tooth brushing on the teeth of a physical avatar in real time. A pilot study conducted with 15 children (ages between 6 and 12) shows that there was possibly positive change of their attitudes to tooth brushing and motivations for tooth brushing when they brushed their teeth with DenTeach. As future work, we plan to develop a smartphone app that interacts with DenTeach so that the children users can constantly check their tooth brushing habits with more fun.
