Honestly, I am very sensitive to all technological things for people with disabilities, I can not deny that they move me. And this seems very beneficial for those who can not see. I think it's very beneficial, because you can feel a little more, although it's not the same as seeing but you can get closer to the senses, right? and with the technology sweeping, I do not doubt that it will surprise us as I was surprised by this bracelet that helps people to facilitate their day to day.
