ABSTRACT

A systematic review did not show any usability evaluation tool specifically developed for blind people. This paper reports an empirical study, investigating the similarity between usability evaluation tools for people with visual impairment. A total of 87 blind people from both genders, equally distributed, from 18 to 75 years old, with congenital blindness were reached. The hypothesis is that a tool using onomatopoeia could be similar to another tool that uses human expressions. Thus, this research compared the Circumplex Model of Affect emotions list and an onomatopoeic prototype using Chi². The results show a similarity between the two tools. Therefore, the findings suggest that the prototype based on onomatopoeia allows blind people to evaluate product usability. In addition, this paper presents a process to build similar tools for people with visual impairment.

摘要

系统评价没有显示任何专门为盲人开发的可用性评估工具。本文报告了一项实证研究，调查了针对视力障碍人士的可用性评估工具之间的相似性。共有 87 名先天性失明的男女盲人参与，分布均匀，年龄从 18 岁到 75 岁。假设使用拟声词的工具可能与使用人类表达的另一种工具相似。因此，本研究比较了情感情绪列表的Circumplex模型和使用Chi²的拟声原型。结果显示这两个工具之间有相似之处。因此，研究结果表明，基于象声词的原型可以让盲人评估产品的可用性。此外，
