The legal definition of AT is broad based and can include low-no tech options for students such as pencil grips, slant boards, picture boards and Braille books, to support performance in the functional skill areas.
When higher level technologies are used, performance can also be enhanced through modifications to computer input and output. The manual effort required to operate a computer and the visual and auditory input/output can be modified.
Modifications can be internal and built into the operating systems of computers. Or, they can be in the form of peripheral devices or specialized software.
