摘要
图纸是工程师的语言,对盲人■来说,触觉图学更有其重要意义。盲生要了解所在学校的结构,若有该校的触觉布局图,很快就能获取信息,但国内外对触觉图学的研究还处于起步阶段。文章探索盲人的“触觉识图”机理、“无障碍触觉图形”基本要素的设计理论与应用,从工程图学角度,把明眼人识别的各种基本技术图线转换为盲人依靠触觉可以识别的线性点位标准组合,以及无障碍触觉图形的标注问题等,最终使盲人尽可能像明眼人那样运用基本的技术图纸。
Drawings are the language of engineers,and tactile graphics is more important for people with visual impairment().The students with visual impairment need to understand the structure of their school.If they have the tactile layout graph of the school,they can quickly obtain the information.However,the study on tactile graphics at home and abroad is still in its infancy.The paper studies the mechanism of“recognizing graph by tactile sense”for the people with visual impairment,explores the design theory and application of the basic elements of“barrier-free recognizing graph by tactile sense”,discusses how to convert various basic technical drawings and lines for the sighted people into a standard combination of linear dots that the people with visual impairment can recognize by tactile sense from the perspective of engineering graphics,and analyzes the labeling problem of barrier-free tactile graphics,in order to make people with visual impairment use the basic technical drawings as possible as the sighted people.
