People aging with long-term disabilities are likely to experience challenges performing everyday activities. Technology holds great potential to help people aging with disability overcome barriers where they live, work, and play and ultimately enhance their quality of life. A comprehensive understanding of their user needs is crucial to drive effective technology innovation. Building upon previous research, we are continuing efforts to understand activity challenges in-depth among older adults with long-term vision, hearing, and mobility disabilities. We are expanding participatory research studies, including interviews and surveys, to identify critical technology needs among a larger and more diverse sample of people. Specifically, we are engaging people from underrepresented racial/ethnic groups about their everyday challenges and assessing the needs of those aging with long-term disabilities still in the workforce. This project will provide the groundwork to drive new research and guide the design of new technologies for this understudied population.
