A Study of Graphics Editor System Aimed at Supporting Visually Impaired People

Abstract

Sighted people use not only verbal information, but also visual information in order to understand the subjects such as mathematics and physics and so on. Although visually impaired people are able to access visual information when the information is expressed by a tactile graphic, it is quite difficult for them to produce figures by themselves. Using refreshable braille display and keyboard is one of the possible methods when visually impaired people draw figures by themselves. So, we will discuss an assistant system for visually impaired people to draw figures by themselves using refreshable braille display and keyboard.
