DOS TRIANGLE

DOS Triangle

A Mathematics Scratch Pad for the Blind


DOS Triangle is a DOS computer program designed for print-impaired students and professionals in math, science and engineering. This program was completed a number of years ago and is still available for any DOS user who wants it. However the Science Access Project can no longer provide support for the program. It works well with VocalEyes and DOS Jaws, which were the two most popular DOS screen readers. The Windows version of Triangle has been under development since 2001 and is now an open source project of Oregon State University's Technology Access Program. The graphing calculator that is part of DOS Triangle has been expanded into a powerful Windows application, the Accessible Graphing Calculator, now available commercially from ViewPlus Technologies, Inc.

DOS Triangle uses a linear notation for representing mathematical expressions, and provides means for evaluating and plotting expressions. Triangle's table viewer allows users to read, navigate, and edit complex tables in an easy-to-use manner.
