Assistive technology is any kind of technology that can be used to enhance the functional independence of a person with a disability. Often, for people with disabilities, accomplishing daily tasks such as talking with friends, going to school and work, or participating in recreational activities is a challenge. Assistive Technology (AT) devices are tools or services to help to overcome those challenges and enable people living with disabilities to enhance their quality of life and lead more independent lives.
Assistive technology devices can be anything from a simple (low-tech) device such as a magnifying glass, to a complex (high-tech) device, such as a computerized communication system. It can be big — an automated van lift for a wheelchair — or small — a grip attached to a pen or fork by Velcro. Assistive technology can also be a substitute — such as an augmentative communication device that provides voice output for a child who cannot communicate with her voice.
