Graph-It is designed to emulate the features of a graphing calculator and works in much the same way. Students type in equations, press a simple print command, and in a matter of moments, the graph begins to appear on the . embosser. Graphs are clear, concise, accurate, and easily read by both the blind with touch or by the sighted visually. One may graph up to ten equations simultaneously on the same x-y axis. Blind students can listen to a tone rising and descending in conjunction with the way the graph rises and descends visually.
Audio graphs are perfect for in-class use with an ear phone.
For blind students in business and finance courses, Blazie Engineering offers F-Calc. This handy, optional program has most of the standard functions available in the average financial calculator. F-Calc presents the blind student with a simple, menu driven user interface of functions from which to choose. F-Calc performs the chosen function on the variable information given by the student and presents the answer in either speech, Braille or both. As with the basic and scientific calculators, any result may be transferred to the clipboard for pasting into homework assignments.
