| 目的 针对盲文书写错误率偏高的问题，探索盲文书写修改器的创新设计路径。方法 首先通过用户访谈来了解盲生对盲文书写修改器的用户需求;其次根据QFD理论构建用户需求与技术目标之间的关系矩阵，得到技术目标的优先级排序，确定盲文书写修改器设计的关键技术目标;再次引入FBS模型，将关键技术目标转化为功能，通过FBS映射获得盲文书写修改器的结构化信息;最后根据分析结果进行盲文书写修改器设计实践。结果 F12(按键)、F21(点字结构)及F32(修正结构)是技术目标重要度排序前三位，将排序前六位的技术目标分别对应交互功能、点字功能、修正功能、替换功能4个功能，以之作为功能起点进行功能到行为、行为到结构的映射转化，指导盲文书写修改器的设计。结论 验证了QFD与FBS模型在盲文书写辅助工具设计中应用的可行性，从创新设计的角度为盲生提高盲文书写效率提供了新思路。 |

| The work aims to explore an innovative design path of braille writing modifiers to solve the problem of high error rate in braille writing. Firstly, the user demands of blind students for braille writing modifiers were learnt through user interview. Then, the relationship matrix between user demands and technical targets was constructed according to the QFD theory to obtain the priority of technical targets and determine key technical targets for design of braille writing modifiers. Once again, the FBS was adopted to transform the key technical targets into functions and obtain the structural information of braille writing modifiers by FBS mapping. F12 (keys), F21 (braille structure) and F32 (fixed structure) showed up to be the most important. The top 6 technical targets were corresponded to the four functions of interaction, braille, modification and replacement and then taken as the functional starting point to achieve the transformation from function to behavior, and from behavior to structure mapping to guide the design of braille writing modifiers. The study verifies the feasibility of QFD and FBS model in design of braille writing assistive tools, which provides a new idea for improving the efficiency of braille writing for blind students from the perspective of innovative design. |
