Body-Braille System for Disabled People

This paper introduces the Body-Braille system which has been developed as a new communication channel for deaf-blind people using 6 micro vibration motors to present a Braille character and describes the support system using the Japanese mobile communication system combined with Body-Braille. Body-Braille has several advantages compared to other Braille systems. The control device of Body-Braille is named “B-brll” and has several interfaces including RS-232C and DTMF. Some basic experiments to measure the speed of reading Braille were performed and the mean reading time for one Braille cell was 0.5-1.4 seconds, which is fast enough for some useful applications. Using Body-Braille, a Tele-support system was developed as an application and good results were obtained. Furthermore, a newly developed idea which presents Braille character using only 2 points instead of 6 points and new equipment corresponding to this idea which has significant possibility for a very practical products, are described

The Development of a self-learning system of Braille reading and writing for visually impaired people and sighted people

The development of a self-learning system of Braille reading and writing for both visually impaired people and sighted people is described. This system consists of a reading sub-system and writing sub-system, and in the reading sub-system, a learner can study the rules and read the presentation of Braille codes separately. In the writing sub-system, a learner types Braille codes into a computer through an external ten-key box mapped to 6 points of a Braille code. In this paper, the detailed explanation of the system and the result data are shown. Since it has been developed very recently, we don't have enough data now, but the result data shows the effectiveness of this system
