摘要
运用实验研究法,测量了39名盲生对由凸线、凸面、热成型和质地四种方法制作的几何图形的正确识别率和识别反应时。研究结果表明:(1)制图方法对盲生触摸识别几何图形有影响,盲生对质地图的正确识别率高于凸线图和凸面图;(2)触摸图形使用频率对盲生触摸识别几何图形有影响,与低使用频率盲生相比,高使用频率盲生的正确识别率更高、反应时更短。
This study, by using an experimental method to test 39 visually-impaired students in their recognition of geometric shapes produced with the methods based on convex line, convex surface, thermoforming and texture, aims to explore visually-impaired students＇ rate of correct recognition of geometric shapes and response time. The results show the following： （1）The mapping methods affected the visually-impaired students＇ correct recognition rate, and the students showed a significantly higher rate of correct recognition of the geometric shapes produced with the method based on texture than with the methods based on convex line and convex surface; （2）and those with a high-frequency use of touch graphics showed a higher rate of correct recognition of the geometric shapes and a shorter response time than those with a low-frequency use of the touch graphics.
