Universal design aims to create products and environments that can be used by all people without needing adaptation. It has seven principles including equitable use, flexibility, and low physical effort. An example of universal design in education is the ULTimate Reader, an electronic textbook that adds visuals or spoken voice to help students develop independence. While teachers see benefits, universal design is difficult to fully integrate into classrooms but developing technology skills and a flexible curriculum can help. Examples of universal design applications include auditory output, wide spaces, and intuitive controls.
