摘要
为解决视障学生对于扳动手法中快速收发力的学习存在不易掌握与难以评估等问题。通过解构现有扳动手法的练习方式,对视障群体进行了需求、使用方式及信息通道分析,结合扳动手法的瞬息收发力特点,开发了引导和评估扳动手法学习的便携设备,将触觉与听觉作为视障同学与设备的主要接纳和信息通道,设计了一款方案并给出测试样机。研究发现:通过听觉、触觉通道输入输出信息,可引导视障使用者练习快速收发力,辅助理解收发力学习要领,获得有效练习回馈,加强练习意愿。
Visually impaired students were hard to master and evaluation fast manipulation in the pulling method. In order solve this problem, the analysis of requirement, way of use and information channel were performed on the visually impaired groups through the deconstruction of existing training methods of fast manipulation. A portable device for guiding and evaluating pulling maneuvers was developed combined with the characteristics of the instantaneous transmitting and receiving force of pulling maneuvers. The sensation and audition were regarded as the main channels of reception information for visually impaired students to design a scheme and produce a prototype. The results revealed that fast manipulation training could be guided and the learning essentials were auxiliary understanding. The effective training feedback was obtained and training willing was strengthened.
