Awesome read @samminator, most of the informations here are new for me. However, i have some concerns
Some could be asking; what's the need of using this type of system, and why not just display the damn file on a computer screen?
Okay here's the thing: Have you ever taken time to ask yourself how blind people would have the privilege of interacting with their physical environment?
Concerning the above, there are changes that occur in the brains of people once they go blind. The brain restructures itself to adapt to the new situation Find more information here
I'm sure you've heard of Neil Hardisson who was born blind. He got an antenna implant in his brain that enabled him to sense colours.
What of the people that are born blind, does the neuroplasticity apply to them too?
Thanks for coming around
