This document defines assistive technology as any item, equipment, software, or product that increases, maintains, or improves the functional capabilities of individuals with disabilities. It describes four levels of assistive technology: no-tech solutions that use existing procedures and environments, low-tech items that are less sophisticated, medium-tech mechanical devices, and high-tech devices that incorporate advanced electronics and computers. Examples are provided for each level ranging from physical and occupational therapy to communication devices and computer programs. Resources for finding additional assistive technologies are also listed.
