The blind can do reading only by touching the braille and it is easy to most of them.But when they want to take notes, it is turn out to be very difficult .
Based on the reading habits of the blind ,we designed a "ring" can be set as the sensing device at your fingertips, brush it lightly following the induction of contact paper, brush, depending on the pressure will identify access to the text, and store the massege it got in internal memory chip,After the ring is connected to a computer or braille reader,the stored massege can be easily transformed into audio or braille.
To the blind,this can help them to learn easier.
