Area of Science:

  • Artificial Intelligence
  • Gerontology
  • Human-Computer Interaction

Background:

  • Intelligent systems offer automated resident well-being assessment.
  • Functional health, the ability to perform activities independently, is crucial for well-being.
  • Smart home technologies provide a platform for unobtrusive activity monitoring.

Purpose of the Study:

  • To introduce a machine learning-based method for assessing activity quality in smart homes.
  • To validate the automated assessment of activity quality against direct observation.
  • To predict cognitive health based on smart home activity quality.

Main Methods:

  • Developed a machine learning model to assess activity quality using smart home sensor data.
  • Recruited 179 participants to perform complex activities in a smart home apartment.
  • Quantified activity quality and correlated it with direct observation scores.

Main Results:

  • Observed a statistically significant correlation (r=0.79) between automated and direct observation scores for activity quality.
  • Achieved an Area Under the Curve (AUC) of 0.64 for predicting cognitive health using machine learning based on task quality.
  • Demonstrated the feasibility of using smart home data for functional health assessment.

Conclusions:

  • Automated assessment of activity quality in smart homes is a valid approach.
  • This technology can contribute to understanding everyday functional health.
  • Machine learning analysis of smart home activities is a promising tool for cognitive health prediction.
