For students with visual impairments, the material may be in a font that is too small; it may be in a font that makes it difficult to distinguish between characters; or the individual’s visual acuity may not allow the ability to read text in any font. In the case of students with learning disabilities, letter reversals, problems with line tracking and over all difficulty with reading vocabulary and comprehension may be a huge roadblock to reading words in print and, therefore, academic success.
Screen Readers - Assistive Technology for Visually Impaired Students
With the increased use of computer scanners, many older students are using screen reader software programs to address these issues. First, the text is scanned into the computer. Then specialized screen reader software is used. What can these screen readers do?
- Read the print word aloud.
- Read the bold faced or highlighted words.
- Read the information on some tables. The “reading” of tables, graphs, and other visual aids is somewhat limited.
Is using a screen reader feasible for students of all ages?
No technology is appropriate for every age. Similar to using recorded books, a student should have a certain degree of ability to work the technology (in this case the program on the computer). He should also have the maturity to take in new information by listening for a period of time. In some situations, as with the learning disabled student who may learn best through auditory channels, a screen reader may be just the answer.
As with any technology, not every software program works with every computer system. If in doubt, it is wise to rely on the expertise of adaptive technology experts from the student’s school or from a reputable organization such as the American Foundation for the Blind.

What other material modifications are available for children with visual impairments?
- Books on Tape – books recorded on cassette tape or CDs
- Large print books – books with larger than normal font. These books are very large.
- Software to increase computer font size – This software works with a PC computer screen to enlarge font to a readable level.
- Braille books – books produced to be read by running the fingers across a line of raised bumps.
- Braille typewriters – machines that create a raised reading form.
- Paper with raised lines – paper with lines that are recognizable to the touch.
Additional types of technology used by the visually impaired or blind is discussed at the Ability Hub.
