触觉凸图在视障人群教学中的应用探索

Exploring the Application of Convex Tactile Graphics in the Teaching Process for Visual Impaired People

触觉凸图是针对视障者的特点,将平面图形做成可触摸的突出于纸张表面的凸起图形。将触觉凸图运用在教学中,能有效解决盲生在学习中难以感知和理解的问题,提高其学习效率。通过对目前常用的4种触觉凸图的制作方式及其特点进行分析,对触觉凸图在视障教学中的有效应用进行了探索。

Convex tactile graphics are designed based on the visual impaired people’s special needs,which transform flat graphics into touchable and convex graphics.Applying convex tactile graphics in the teaching process helps blind students to recognize and understand knowledge more efficiently.By analyzing the production process and the properties of four common types of convex tactile graphics,we explored the effective use of convex tactile graphics in teaching for visual impaired people.
