Researchers at the Toronto Rehabilitation Institute are developing artificially intelligent, self-adaptive homes that will allow individuals with mental impairments such as Alzheimer's disease to safely live at home. Among the features are a talking bathroom that provides visual cues to assist with hand washing. Ceiling-mounted cameras throughout the house provide it with visual recognition, allowing it to always know the location of the patient and detect if they have fallen. The house has speech recognition, allowing the patient to ask for help at any time. The patient's requests don't have to be pre-programmed because the "systems use computer algorithms that act more like a human in terms of rational thought and decision-making. They actually learn and adapt to a person's needs."
