I read an article about how to live blind programmers and saw the cost of the devices required to operate the computer. After some thought, had invented a device that would have a very large cost. Wanted to create a startup that would be involved in the production of such pieces (and in the future, and other pieces, useful for the disabled).
Is there someplace I can view the approximate number of blind people in the CIS? It is necessary to count the approximate number of buyers for your business plan.
