Heading sounds exciting.
There is a MIT’s event going to happen next week (8th of July 2013), I was planning to participate but unfortunately I was not be able to get in and so I wanted to everyone else to know what I was thinking since last 2-3 weeks.
I am not much a electronics guy and trying to learn electronics, So please do tell me my mistakes so that I may improve it.
This concept is just a concept which I haven’t demo it yet and was planning to create a prototype in the event but unfortunately not selected so trying to tell everyone so that I may have inputs form them and if someone like it then they may implement it.
Link to the event is here
I personally believe that there are not much of the good devices are in market which would give the realtime experience to the visually challenged people.
So this concept is to convert every digital media to the braille.
Best part of this is it is not just for english or something it would be able to all symbols and languages to braille.
Person readin the reader will have experience of reading the real book and not just books we may convert webpages and other digital media to braille.
There are not much pictures available but will try to provide you that within few days as I got no camera and no electronics which I may provide.
Constraints for present Prototype:
I am converting all the data to 1 particular font for present and I am keeping the size to tbe constant for every media.
Screen used: Something similar to magnetic slate thing which works on the principe of magnetic field.
Link to Magnetic slate
I have no idea how to do this so this is my next task to make this screen work something similar to that of kindle reader.
and increase the magnetic field by providing the power.(not sure how research in progress)
As my research says the E-ink technology works we may develop something similar with it as that of kindle screen which is a Ebook reader.
Let’s place this screen directly above a bread board, which got office pins in it.
Now as the image produce over the screen it will produce a magnetic filed which will pull the office pins towards it.
As we all know that magnetic force would be vectorial in nature, for those who don’t read it from here http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magfor.html
Now those pins which are directly below the screen will pull those pins towards it and the pins which are not directly below will face the force component in some specific degree so it won’t be pulled up that much as that of the pins directly below the symbols (remember that symbols are magnetic)
Now time is mesure the distance with which the pins are up than.
This is all what I am sure about after that I an not sure about things
We may trigger the circuit by measuring the moved screens from below the bread board and then to trigger the screen.
1) It is fast
2) Will convert the all those alphabets to braille which are shown in the screen.
3) will have the real feel of reading the book or watching the webpage in realtime.
For now the only constraint of font and size and I am not sure this really matters or not.
Different ideas which are kind of similar and this idea is inspired form them
1) A braille reader can read up to 200 words per minute
2) Zixel: A 2.5-D Graphical Tactile Display System
3) World’s 1st Braille Smartphone for Blind People

Would love if someone feel like to implement this at there end and would love to extend this 🙂
My work for autistic people is over my another blog, This was my 1st blog for Visually challenged people, Will post more updates over this work very soon.
