Abstract: Braille alphabet is an important tool that enables
visually impaired individuals to have a comfortable life like those
who have normal vision. For this reason, new applications related to
the Braille alphabet are being developed. In this study, a new
Refreshable Braille Display was developed to help visually impaired
individuals learn the Braille alphabet easier. By means of this system,
any text downloaded on a computer can be read by the visually
impaired individual at that moment by feeling it by his/her hands.
Through this electronic device, it was aimed to make learning the
Braille alphabet easier for visually impaired individuals with whom
the necessary tests were conducted.
Abstract: Along with the increased morbidity of glaucoma or
diabetic retinitis pigmentosa, etc., number of people with vision loss is
also increasing in Japan. It is difficult for the visually impaired to learn
and acquire braille because most of them are middle-aged. In addition,
number of braille teachers are not sufficient and reducing in Japan, and
this situation makes more difficult for the visually impaired. Therefore,
we research and develop a Web-based e-learning program for tactile
braille, that cooperate with braille display and voice assistance.
