[Blindmath] analyze of experimental results

[Richard Baldwin]

I will ramble on here a bit with a few ideas for you to try.

If you can get that data into an image file, such as a JPG file, the vOICe
Learning Edition software at http://www.artificialvision.com/ will convert
it to audio.

If you have it as a printed graph and you have a webcam, such as are often
built into laptop computers, (or a static digital camera) and a sighted
friend to assist you, you can take a picture of it, save it in a graphics
file, and then play it with the vOICe software. (You may need to clean it up
first using graphics software as described below.)

If you need a way to analyze the graph using touch, ask your friend to use
the Trace Bitmap feature on the Path menu of the free InkScape software to
convert it into an svg file. Then ask your friend to use the InkScape
software to add gridlines, tic marks, or anything else that may be needed,
use the Flip Horizontal item on the InkScape Object menu, enlarge it to fit
the largest printer that you have access to, print it, emboss it using a
serrated tracing wheel and give you the embossed image.

If you are fortunate enough to have access to a ViewPlus graphic embossing
printer, download the free IVEO Viewer software, open the svg file produced
by InkScape in the Viewer software and print it on the ViewPlus graphic
embosser.

Insofar as getting that data into an image file, my first thought is to ask
your friend import it into a spreadsheet program and graph it. If the
spreadsheet program doesn't have the ability to write it as an output
graphic file, display it in maximum size on the screen, press
Shift-PrintScreen (Windows) to copy it onto the clipboard and then paste it
into any of a number of free graphic programs such as Paint.net. Use that
program to trim off the excess garbage and write it back out as a jpg, png,
bmp, or other graphic file for further processing.

I will be interested in the solutions proposed by others on this list.
