Assistive technology is any item, equipment, or product system that is used to increase, maintain, or improve the functional capabilities of individuals with disabilities. The Technology-Related Assistance for Individuals with Disabilities Act provides funding for assistive technology programs and services. Examples of assistive technology include hearing loop systems for the hearing impaired, optical character recognition and braille embossers for the visually impaired, text-to-speech software for students with dyslexia, and wheelchairs and walkers for individuals with physical disabilities.
