Voice-activated digital assistants, such as the Amazon Alexa devices, have great potential to support people aging with mobility disabilities. Alexa can be integrated with a variety of smart home technologies, such as robotic vacuums and smart light bulbs, to help people with limited mobility complete activities at home as independently as possible.

In this project, we are conducting in-home evaluations of new digital voice assistant applications for smart home technologies being developed as part of the D4. Developing Voice-Activated Digital Home Assistants Project. We are specifically looking at applications to support people in controlling their home environment, engaging in physical activity, interacting with others, and managing their health. Through this research, we will explore to what extent the applications and the instructional user guide are practical, useful, and effective in improving the lives of users.

Project Status

We are wrapping up our “Digital Assistance in a Box” (DAB) field trial, where we are providing our specially designed technology suite to older adults with mobility disabilities to assess the benefits and barriers of integrating smart technology within their lives to assist with in-home daily activities. The DAB contains a digital home assistant (Amazon Echo Show), smart light, and smart plug, as well as dedicated instructional materials designed with older adults in mind. These manuals were a product of the D4. Developing Voice-Activated Digital Home Assistants Project.

We now have developed 5 Amazon Echo User Guides: Basic UsesSetting Up, Social CommunicationEnvironmental Control, and Health Applications.
