Suzy the Hygiene Circle was created by students for a 12-year-old girl named Mia with Down syndrome. Mia needed help with daily tasks like brushing teeth but had low reading levels. The students built Suzy, an interactive tool using a wooden lazy Susan, cups, switches and a singing greeting card to help Mia brush teeth, wash face and hands independently through fun interactions like high fives. They detailed the building process which involved woodworking, circuits and switches to create Suzy and demonstrated it for Mia, discussing pros, cons and possible improvements.
