Assistive Technology

Assistive technology (AT) is any item, piece of equipment, software program, or product system that is used to increase, maintain, or improve the functional capabilities of persons with disabilities (Assistive Technology Act of 1999).

Large Print or Talking Calculator

A talking calculator has a built-in speech synthesizer that reads aloud each number, symbol, or operation key a user presses; it also vocalizes the answer to the problem. A large print/button calculator is designed for use by individuals with fine motor disabilities or low vision.

Magnification Technology

Magnification helps those with low vision by enlarging text in print and on computer screens. Products in this group can range from a simple magnifying glass to screen enlarging software to video magnifiers.

Screen Reader

A screen reader is a type of assistive technology that allows student with a visual impairment to read the content on a computer screen with a voice synthesizer or braille display. JAWS, VoiceOver, and NVDA are examples of screen readers.


Text-to-speech (TTS) is a type of assistive technology that reads digital text aloud. It's sometimes called “read aloud” technology. Kurzweil 3000, Natural Reader, and Immersive Reader are examples of text-to-speech.
