Scientific Reading and Writing by Blind People - Technologies of the Future The paper explains both how Nemeth studied and developed his own techniques for learning and teaching advanced math subjects. The text of an excellent presentation to the Mathematical Association of America in January 1996. Learning and Teaching Math by Abraham Nemeth This paper, written by a blind pioneer in the study of math, explains the system he developed for most efficiently working with sighted readers. Traditionally, it was necessary for a blind student studying math to have a sighted reader orally communicate formulas and mathematical expressions, etc. Tips for Reading Math Out Loud to Blind Students by A. Files are uploaded from the pen to a computer using a USB connection." While being an essentially new computer platform, the Smartpen gets most of its information from handwriting rather than a keyboard and a mouse, thereby enabling college students to concentrate on taking notes and then later, when reviewing, tapping the Smartpen to see what the professor was saying when the student took a particular note. It captures more than 100 hours of audio through a built-in microphone and plays audio back through a built-in speaker or 3D recording headset. "The Livescribe smartpen recognizes handwritten marks through a camera inside its tip that focuses on a minute pattern of dots printed on paper. Since its inception in the summer of 1995, this university-funded lab has both served as a production facility for providing visually impaired students with educational materials and as a research lab for developing new adaptive technologies." This page describes some of the ways that the program has functioned to help make advanced science and math courses at Purdue more accessible. "The Purdue University VISIONS Lab, which stands for Visually Impaired Students Initiative on Science, is a research laboratory dedicated to providing access to the numerous science courses at Purdue. Triangle's table viewer allows users to read, navigate, and edit complex tables in an easy-to-use manner."
GRAPHMATICA PICTURES WINDOWS
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 TechnologiesĭOS Triangle uses a linear notation for representing mathematical expressions, and provides means for evaluating and plotting expressions. 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. It works well with VocalEyes and DOS Jaws, which the two most popular DOS screen readers. However the Science Access Project can no longer provide support for the program. This program was completed a number of years ago and is still available for any DOS user who wants it. "DOS Triangle is a DOS computer program designed for print-impaired students and professionals in math, science and engineering. It is the first low-cost system for creating and/or scanning line drawings, graphs, and maps and automatically producing raised-dot graphics on braille embossers typically found in schools and resource rooms." "Create your own raised-dot graphics in minutes using your IBM PC! Picture Braille is a simple-to-use system for producing tactile graphics using IBM(R) computers and braille embossers. Tools to Make Raised Line Drawings in Braille
APH "has compiled a list of websites that contain information about these tips and tools in order to help teachers get their blind students into the loop." Internet Resources for Teaching Math to Visually Impaired StudentsĪ more specialized page on the APH site "for locating resources to help students conceptualize and learn math. While most of this information is directedįor learning through high school, you will still find some things of use for more complicated study. Perhaps the single best source to consult for specialized tools for science and math learning is The American Printing House for the BlindĪre excellent starting places for tools to assist with math and science.
