This simple instructable was born just 10 minutes ago when i stumbled upon "DIY assistive technology for computer access"
This was a great instructable reminding me of a program on seeing with your tongue, I saw the other day.
Here is some information about that: http://www.psychologytoday.com/blog/the-fallible-mind/201107/see-your-tongue
Last night I found a great script visualizing video as ascii made by Andrei Gheorghe (http://github.com/idevelop)
Then the idea was born - why not combine the information!
But I need your help!
Step 1: See With Your Tongue!
I simply installed the script (on my fine Raspberry Pi) and changed the output to bits (0/1).
You can find the result here: http://188.8.131.52/bits/ (This is the datavisualization thing...available in the simplest of formats)
You kan download the original script here: https://github.com/idevelop/ascii-camera/archive/master.zip
I think you can simply make a smaller frame, and make a mechanical piece to use on your tongue and you would have a device that could make a difference for someone without seeing ability.
Update... I changed the settings in app.js, so that the frame update and size is more convenient for a tongue sensor.
The bits are a bit "nervous", but that can certainly be fixed if it is a problem.
But I don't have the knowledge to make the tongue piece... please link to information/instructables below to help others build the tongue seeing device!
