assistive technology [adapted from WCAG 2.0]Jeanne F Spellman, 5 Jan 2009, 21:55:06
Software and/or hardware that provides functionality to meet the requirements of users with disabilities that goes beyond direct accessibility features offered by mainstream applications. Assistive technology functionality includes alternative presentations (e.g., as synthesized speech or magnified content), alternative input methods (e.g., voice), additional navigation or orientation mechanisms, and content transformations (e.g., to make tables more accessible). Examples of assistive technologies include, but are not limited to, the following:
â€¢ screen magnifiers, and other visual reading assistants, which are used by people with visual, perceptual and physical print disabilities to change text font, size, spacing, color, synchronization with speech, etc. in order improve the visual readability of rendered text and images;
â€¢ screen readers, which are used by people who are blind to read textual information through synthesized speech or braille;
â€¢ text-to-speech software, which is used by some people with cognitive, language, and learning disabilities to convert text into synthetic speech;
â€¢ speech recognition software, which may be used by people who have some physical disabilities;
â€¢ alternative keyboards, which are used by people with certain physical disabilities to simulate the keyboard (including alternate keyboards that use head pointers, single switches, sip/puff and other special input devices);
â€¢ alternative pointing devices, which are used by people with certain physical disabilities to simulate mouse pointing and button activations.
