Computer Assistance for Individuals with Visual Impairments Computing facilities can assist visually impaired users by providing instruction sheets, signs, and labels on equipment and support materials in large print and Braille. Anti-glare screens can make screens easier to read. In addition, special equipment and software can enlarge text and graphics on monitors and printers. Special software can also reverse screens from black on white to white on black for individuals who are light sensitive. Voice output can be used to read screen text to blind users.
Braille printers provide output.
Such systems can provide independent access to abstracts, journals, syllabi, and homework assignments. Although hearing-impaired individuals face relatively minor barriers to computer use, some benefit from visual alternatives to audio output provided by some software packages. Additionally, portable computers with voice synthesis can be used as communication devices so that hearing-impaired persons without speech can participate in group discussions. Telecommunication is a particularly powerful tool for students with hearing impairments. With a computer and communications hardware and software they can independently access electronic bulletin boards, databases, electronic mail, discussion groups, and on-line services.
