[Blindmath] Reading graphs and diagrams with sound

[Raju singh]

According to my views, though i am not perfect, i am still in a learning stage,  most of the time, manual diagram had  prove very useful and perfect solution. For example, suppose you draw a rect angle in computer, and use voic to listen. Now, if you know the shape of at list the shape of rectangle, you can grab the sound which voic produce, but if we don't know the shape of rectangle, voic doesn't make any sense for me.

I also agree that sometimes simple solutions are the best.

Also in the learning process its sometimes better to do things manually 
then one understands how the graph is created, not just how one uses a 
software tool to generate a certain chart. I know similar approaches are 
taken for other things (eg. when I was taught statistics I was taught 
how to calculate standard deviation for a set of numbers, although 
calculators have features for doing this for you).

Also I personally feel that as normally a tactile version of the diagram 
relates closer to the visual chart someone would have, it can make it 
easier for communicating ideas relating to the chart.

Once an understanding of the basics is mastered then using computers may 
help, but at least one understands what is going on and possibly will 
pick up when the computer gets it wrong.
