Abstract
Failing to brush one’s teeth regularly can have surprisinglyserious health consequences, from periodontal disease tocoronary heart disease to pancreatic cancer. This problemis especially worrying when caring for the elderly and/orindividuals with dementia, as they often forget or are unableto perform standard health activities such as brushing theirteeth, washing their hands, and taking medication. To ensurethat such individuals are correctly looked after they areplaced under the supervision of caretakers or family members,simultaneously limiting their independence and placing animmense burden on their family members and caretakers. Toaddress this problem we developed a non-invasive wearablesystem based on a wrist-mounted accelerometer to accuratelyidentify when a person brushed their teeth. We tested theefficacy of our system with a month-long in-the-wild studyand achieved an accuracy of 94% and an F-measure of 0.82.
