ABSTRACT

The present lack of suitable and efficient graphics creation techniques may place limitations on the career progression and life contentment of blind students. It is challenging for a BVI (Blind and Visually Impaired) person to draw diagrams or art, which are commonly taught in education or used in industry. The SETUP09 graphics creation system was developed to address a need for blind users to be able to create such content and consists of both navigation and computer aided drawing techniques, enabling graphics creation and manipulation through command language and intuitive, matrix-style movement. The technique can facilitate a user’s ability to produce art and scientific diagrams electronically. This paper presents a comparative system evaluation of digital versus analogue drawing techniques with early and late blind individuals. Users were tested using different graphics creation tasks to assess the accuracy and efficiency of an analogue drawing technique compared with the digital SETUP09 system. The results confirmed that the SETUP09 compass-based graphics creation technique allows greater accuracy in completing a drawing task, with a noticeable reduction in effort compared to analogue drawing techniques.

摘要

目前缺乏合适和有效的图形创建技术可能会限制盲人学生的职业发展和生活满意度。对于 BVI（盲人和视力障碍）人来说，绘制图表或艺术作品是一项挑战，这些图表或艺术通常在教育中教授或在工业中使用。SETUP09 图形创建系统旨在满足盲人用户创建此类内容的需求，该系统由导航和计算机辅助绘图技术组成，可通过命令语言和直观的矩阵式移动实现图形创建和操作。该技术可以促进用户以电子方式制作艺术和科学图表的能力。本文介绍了数字与模拟绘图技术与早期和晚期盲人的比较系统评估。用户使用不同的图形创建任务进行了测试，以评估模拟绘图技术与数字 SETUP09 系统相比的准确性和效率。结果证实，基于 SETUP09 罗盘的图形创建技术可以更准确地完成绘图任务，与模拟绘图技术相比，工作量明显减少。
