I guess there's none. I have never heard of there's any before.
So, it's the Icywallet as the article says but still haven't heard of it and the article was already old.
Yeah considering that the article is already old yet we have not hearing anything close to this one now so it means this is not successful idea?and besides i am not degrading the capacity of blind people because they are also human but i dont think Bitcoin is created for them to venture or even to invest,not unless they have someone trusted that can make a transaction for him possible?since it is very risky for a blind person to use voice activated transaction or other form that can offer only for Blind people to be accessible with.
But who knows if there will be a group of developers that will continue this kind of projects.
Honestly, this is an amazing project if ever someone will continue to develop or give attention to this idea. That's how technology works, solving a certain problem and giving ease to its users.
