Abstract
A method of providing language assistance to a computer user with dyslexia, reading disabilities or visual impairment by presenting text-based information via multiple media channels. The method of the present invention includes the steps of: accessing a source of text-based data that can originate from a computer text document, displaying text-based data in a text window with a standard font size, displaying the text-based data in another text window with a magnified font size, sequentially highlighting the text-based data in the magnified text window one word at a time; generating synthesized speech signals representative of the highlighted text; rendering the synthesized speech signals audible synchronously with the displaying of the highlighted text; displaying images that correspond to the context of the highlighted text; and generating sound effects that are pertinent to the context of the highlighted text such that text-based information and corresponding graphical and audible information can be perceived simultaneously by the user.
