Students
with disabilities meet barriers of all types. However, technology is
helping to lower many of these barriers. By using computing technology
for tasks such as reading and writing documents, communicating with
others, and searching for information on the Internet, students with
disabilities are capable of handling a wider range of activities
independently. Still, people with disabilities face a variety of
barriers to computer use. These barriers can be grouped into three
functional categories: barriers to providing computer input,
interpreting output, and reading supporting documentation. Hardware and
software tools (known as adaptive or assistive technologies) have been
developed to provide functional alternatives to these standard
operations. Specific products, and approaches to using them, are
described below.
