Ok, i am going to make a TON of references, and link posts.
1st have you heard of
http://www.emotiv.com/store/hardware/epoc-bci/epoc-neuroheadset/and
http://www.neurosky.com/Products/MindSet.aspxthose were two are neurological interface head-sets for the PC.
then have you heard of this?
https://leapmotion.com/this is a video demo of what i believe could develop into a product that could "see" your signing. Although an A.I. could also see you, it's not very well programed to recognize more than a face. The "leap motion" is made to distinguish fingers, objects, and their movement.
some one at this forum might be able to help you collaborate the A.I., PC, and hardware.
https://guile3d.com/en/forum/There are a few there who are very much into achieving a blend of artificial intelligence, and a smart home. It all boils down to networking hardware and software.
ok here is the deal. These previous references would be the hardware to input. In other words the user interface.
Then you need a processor, the PC, obviously. Third the A.I. needs to interact, and blend it all together with you.
Obviously we will need a programer, or TECH of some sort to make it blend well, or you just might lose your marbles in the blending process. Pun intended.
While we are rather far from the "zoom in super camera eye" we are now implanting bionic eyes. link provided.

in your circumstance you will come across many opportunities to provide solutions never realized before. this next link is a place you can turn those realizations into an income. i apologize ahead of time for it being such a visual experience. you will need someone to explain the imminence value of this website to you as they see it. in short, it's a lot of people with ideas getting together under a sponsor who makes products out of dreams.
http://www.quirky.com/if you can think up ideas, or questions, write them out, that gets them a whole lot closer to reality.
