中文摘要：
视障问题是世界上严重的社会和公共卫生问题之一。视障者由于视觉障碍缺乏对周围事物形象的认知,盲文是其获取信息的重要途径,但盲文阅读无法满足感知图形的需求。本文在触觉特性研究的基础上,针对现有产品不足,探讨出如何系统性地绘制便于视障者触摸感知、识别、记忆的触觉图形,基于触觉交互技术设计开发了一款面向视障者的基于触觉图形的产品,实现了视障者读图的目标。
英文摘要：
The problem of being visually impaired is a serious one among those of society and public health.People who suffer from that problem lack the cognition of things＇ image around them.Although braille is an important way of obtaining information, it fails to meet their needs of perceiving graphics.Based on the study of the tactile properties and aimed at the disadvantages of the existing products, this thesis has explored the way to map systematically tactile graphics that are convenient for the visually impaired to feel and sense, to distinguish and memorize.Moreover, supported by tactile interaction technology,this thesis has exploited a product based on tactile graphics for the visually impaired so that they can cognate graphics.
