Computers Address Hearing, Sight, and Cognitive Disabilities

Because of its versatility, the computer can be the tool that overcomes many physical disabilities such as hearing, sight, and cognitive disabilities. With a hearing disability, the computer can easily substitute words and images for sounds. Because the computer is so sight-oriented, you would anticipate fundamental drawbacks. Technology to the rescue. With the introduction of today’s multimedia programs, alternatives to audio information have been developed that offer a display of visual feedback.

Yes, the computer is a visual tool, but it can be modified to accommodate the visually impaired. Both software and hardware can be designed for use by the visually impaired. Programs such as screen readers like the popular JAWS program speak what the computer displays. Braille keyboards and screen magnifiers are popular aids. Key guards and other alternative keyboards are also available. The keytops of some special keyboards have text in a size and color that a visually impaired or mentally retarded person can easily see and read.

For cognitive disabilities, head mounted pointers and voice input, also known as speech recognition, are available. Users can simply speak commands into a microphone connected to the computer. For persons with limited mobility and dexterity, ultra-sensitive hyperlinks called hovers allow use of alternative mouse equipment to activate a link just by coming within range.
