重度視覚障害者が利用可能なベクタグラフィックスの開発

抄録

Blind people cannot draw figures by themselves. However, a blind physics teacher working at a university, for example, deeply wants to produce figures for his lectures by himself. In order to support for blind people to draw figures by themselves, some of the assistive systems have been developed [1, 2, 3, 4], but they are not practically used by the visually impaired. This is because, the produced figures are not precise enough to share sighted people or it requires long time to complete a figure. Based on this background, we are now developing a formal language of vector graphics, which is available for the visually impaired. This paper introduces our vector graphics and explains how it is useful for the visually impaired.
