Universal Design

Universal Design is the design philosophy and practice of creating products, environments, and systems that are usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. Originating in architecture through the work of Ronald Mace at North Carolina State University, the concept has been widely adopted in digital accessibility, education, and product design. The seven principles of Universal Design include equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, and appropriate size and space for approach and use. In education, Universal Design for Learning (UDL) and Universal Design for Instruction (UDI) apply these principles to curriculum and pedagogy, ensuring that learning materials and activities are accessible to students with diverse abilities from the outset rather than requiring retrofitted accommodations.
