盲人通常在学校和日常生活中使用低科技的模拟工具完成绘画任务。这些工具缺乏绘图支持和错误纠正。为了克服这些问题，存在用于数字图形访问和创建的系统。本文分析了几个支持非可视化绘图的软件项目。分析是用来提取的数字非视觉绘图系统的开发人员和用户的需求。基于文献的调查结果扩展到涵盖ISO 9241-110标准原则的四类35项要求的更完整的清单。随后，分析的项目进行测试，对拟议的检查表。最后，六个盲人对每个需求的重要性进行了评级，以提示哪些功能对用户的接受度最重要。
Blind people normally fulfill drawing tasks with low-tech analog tools in school and everyday life. Such tools are lacking in drawing support and error correction. To overcome these problems, systems for digital graphic access and creation exist. In this paper, an analysis of several software projects for non-visual drawing support is performed. The analysis is used to extract requirements for a digital non-visual drawing system from developers and users. The literature-based findings are extended to a more complete checklist of thirty-five requirements in four categories that cover the principles of the ISO 9241-110 standard. Subsequently, the analyzed projects are tested against the proposed checklist. Finally, six blind people rated the individual importance of each requirement to give a hint which features are most important for user acceptance.
