A mão de robô que deixa uma pessoa surdocega ler o mundo sozinha

Some people cannot see and cannot hear. We call them DeafBlind. They read words with their hands. Another person makes signs inside their palm, letter by letter. So they always need somebody close to them.

Now a robot does this job. It is a hand on the table, about the size of a real hand. The person puts one hand on top of it. The robot makes the letters of the alphabet in sign language. It reads a phone call, a website or an alarm. And it works at any hour of the day.

Samantha Johnson builds it in Boston. She meets a DeafBlind woman at a university event and never forgets it. Her company sends twenty-five of these hands to people this year. The robot does not replace a friend. It gives back one simple thing: you do not have to wait for help to know what happens.
