Finger Braille Teaching System for People who Communicate with Deafblind People

“…In session 4, sender 2 dotted conversation 4 displayed by presentation method A. The senders were directed: (1) to dot as accurately as possible; (2) to dot long in characters at the end of clauses and sentences;…”

“…An et al carried out an experiment that ten visually impaired people who just started to learn Braille codes inputted Braille code using a Braille typewriter [2]. As a result, error ratio was 2.8r2.3% and input speed was 135.9r 37.0 characters/min.…”

“…Recently, some Braille input devices were developed [2], [3]. These devices let deafblind people wear gloves or an keyboard to input his/her Finger Braille and actuators to output non-disabled people's speech converted to Finger Braille.…”

Finger Braille Teaching System

“…As mentioned above, An et al (2004) carried out an experiment in which ten visually impaired people who had just started to learn Braille codes inputted Braille code using a Braille typewriter. As a result, the error ratio was 2.8±2.3% and the input speed was 135.9±37.0 characters/min.…”

“…Because there is such a small number of non-disabled people who are skilled in Finger Braille, deafblind people communicate only through an interpreter. Various Braille input devices have recently been developed (Amemiya et al, 2004;An et al, 2004), but they require deafblind people to wear gloves or type on a keyboard to input the Finger Braille, or to use actuators to output and convert the speech of non-disabled people to Finger Braille. With these devices, deafblind people are burdened with wearing sensors and actuators, and they must master a new communication system with these support devices.…”
