Bathroom assistive technologies, such as toilet safety frames and grab bars, can help people with long-term mobility disabilities safely accomplish tasks like toileting and bathing. However, these features are often fixed environmental supports that can’t be adjusted to accommodate individuals whose support needs vary over time or even fluctuate day-to-day. SmartBathroom is a state-of-the-art bathroom laboratory with mechanically adjustable grab bars and a toilet. It features an array of sensors that can measure walking performance (speed, balance, stability), location of feet and hands, forces applied to the bathroom surfaces. Building upon earlier TechSAge work, we continue to refine and test the SmartToilet, SmartFloor, and SmartGrabbar systems. We are also developing a prototype for a SmartBathing Transfer System to measure an individual’s ability to get in and out of the shower or bathtub. Ultimately, we hope to develop predictive algorithms that can be used to automatically adjust SmartBathroom features to meet the transfer support needs of individuals at any point in time.
 

    

 

Project Status: 

The D1.1 team is currently evaluating the first generation of the Smart Toilet Transfer system in order to ensure best user configuration of system components (floor, grab bars, toilet seat, & cameras). The team is simultaneously developing components for a SmartBathing Transfer System, in order to test showers and bathtubs.  Active recruitment for research participants is underway to test the functionality of the current Smart Bathroom.
