People with developmental disabilities often face
difficulties in coping with daily activities and many require
constant support. One of the major health issues for people
with developmental disabilities is personal hygiene. Many lack
the ability, poor memory or lack of attention to carry out
normal daily activities like brushing teeth and washing hands.
Poor personal hygiene may result in increased susceptibility to
infection and other health issues. To enable independent living
and improve the quality of care for people with developmental
abilities, this paper proposes a new wearable sensing
framework to monitoring personal hygiene. Based on a
smartwatch, this framework is designed as a pervasive
monitoring and learning tool to provide detailed evaluation and
feedback to the user on hand washing and tooth brushing. A
preliminary study was conducted to assess the performance of
the approach, and the results showed the reliability and
robustness of the framework in quantifying and assessing hand
washing and tooth brushing activities.
