This paper presents a real-time vision-based system to assist a person with dementia wash their hands. The system uses only video inputs, and assistance is given as either verbal or visual prompts, or through the enlistment of a human caregiver’s help. The system combines a Bayesian sequential estimation framework for tracking hands and towel, with a decision theoretic framework for computing policies of action. The decision making system is a partially observable Markov decision process, or… CONTINUE READING
