This is probably the last idea for a revolutionary invention that I have, but what about an augmentative communication device for the visually impaired?
I think that there needs to be a way to put braille on an AAC device. Not everybody that has a speech impairment can see. I mean, raised letters were used before braille, but I can’t imagine them on an AAC device. I think that braille would work better on a computer screen.
Again, it’s just my idea. What do you think? Helpful, not helpful or the tip of the iceberg?
