Universal Usability

An approach to technology design that aims to make systems usable by the widest possible range of people, including children, older adults, people with various impairments, people engaged in other tasks, and users with differing levels of education, literacy, and socio-economic resources. Universal usability extends the concept of universal design into the digital realm, emphasizing that technology should accommodate not just disability-related needs but the full spectrum of human diversity in ability, experience, and context of use. It overlaps with but is distinct from web accessibility, which tends to focus more narrowly on disability-related barriers and standards compliance.
