Steps involved in perform sensor-assisted cognitive health assessment. The process starts with a comprehensive neuropsychology assessment of the participant. The participant then performs IADLs in a smart home monitored by trained clinicians and smart home environmental sensors. The raw sensor data is annotated with activity labels. From the annotated sensor data, we extract features and analyze it with machine learning algorithms to derive the quality of the activity. The results are used by a clinician or by a computer program to perform cognitive health assessment.
