[nabs-l] Graphing Calculators

[Nicole B. Torcolini]

Per the discussion about graphs and charts:

1. I have used the AGC in the past, but do not remember all of the specifics.  It is self-voicing, so you do not have to worry about screen readers.  It has audio feedback as well as displaying a table of values.  It can be used to analyze an equation or fit an equation to data.  It also works as a regular calculator and even has matrix capabilities.

2. The calculator from NASA is called MathTrax.  It is good for analyzing a graph for which you have an equation.  It will give a mathematical analysis of the graph.  For example, typing the equation for an ellipse will display information such as the foci and semi menor and major axes.  It also has audio feedback.

3. Excel
If you are looking to analyse data and want it in a format that sighted people can easily use, Excel offers some information.  If you graph the data, JAWS will provide some information about the graph.  After an equation is fit to the data, the JAWS cursor can be used to read the equation.

I have briefly experienced another miniature Braille display that displayed graphs.  However, I do not recall the name of it, nor do I know the capabilities the program with which it was used.
