Assistive technology (AT) refers to devices or services that help individuals with disabilities function better. AT ranges from low-tech options like magnifying glasses to complex devices like computerized communication systems. AT services involve evaluating individuals' needs, training users and support systems, acquiring devices, customizing devices, and coordinating devices with other services. Proper assessment and ongoing support are needed to minimize abandonment of AT devices, which occurs in around half of cases due to poor matching of technology to individual needs and abilities.
