Smart Home-Based Health Platform for Functional Monitoring and Intervention


To create a “smart environment” that enables older adults or individuals experiencing cognitive or physical limitations to function independently and remain in their own home setting

Anticipated Impact: 

Cost savings to rehabilitation and nursing care services


By 2040, nearly one quarter of the U.S. population will be 65 years of age or older and many will require some type of monitored living arrangement. A "smart environment" is one that is equipped with low-cost sensors that yield alerts and reminders for the elderly and disabled to ensure they are adequately caring for themselves. In a specifically-built "smart home" environment, the research team will use specialized sensors to monitor whether activities of daily living (ADLs) are being adequately performed and whether ADL monitoring provides a basis for effective interventions using reminders and automated assistance. In 2005 Washington State had several hundred thousand individuals being cared for in nursing homes at a cost of about $94 million per day, not including assisted care or veterans facilities. If one percent of the state’s population is kept at home for two additional years, the result will save Washingtonians approximately $9.4 million a day and $3.4 billion a year.

Grantee Organization:
Washington State University
Grant Title:
Smart home-based health platform for functional monitoring and intervention
Grant Cohort and Year:
2008 Innovative Research Projects to Improve Health and Health Care (01)
Grant Period:
01/01/2009 - 12/31/2011 (Completed)
Grant Amount:
Our LSDF grant to date has allowed us to validate that our computer algorithms can successfully recognize a set of activities of daily living in varied environments including apartments, multi-level structures, and homes with multiple residents. Our project has also been used to show that assessment of cognitive health can be accomplished by monitoring daily activities instead of or in addition to self report and lab-based assessment. Finally, we have verified that automated interventions such as video and audio prompts are effective at helping individuals with mild cognitive impairment to successfully initiate and complete activities that would be difficult for them to consistently perform without the intervention.
