ABSTRACT

In the area of human–computer interaction (HCI) of persons with disabilities (PWDs), the knowledge about the mechanisms determining their evaluation of the assistive technology is particularly important. This study is aimed at exploring the usability evaluation process of an assistive technology on the example of Face Controller (FC). To trace the evaluation process, a comparison of the FC usability evaluation between PWDs (N = 29) and persons with no disabilities (PNDs; N = 32) was performed. The present study revealed that the PWDs reported higher satisfaction and perceived usability of the FC comparing to the PNDs, whereas the effectiveness and efficiency were both lower for PWDs. This asymmetrical pattern of the results in the evaluation of the FC usability is discussed as an extension of disability paradox and can enhance the understanding of conceptualization and evaluation HCI made by PWDs.

摘要

在残疾人（PWD）的人机交互（HCI）领域中，有关确定其对辅助技术评估的机制的知识尤为重要。这项研究旨在以人脸控制器（FC）为例探索辅助技术的可用性评估过程。为了跟踪评估过程，比较了残疾人（N = 29）和残疾人（PND；N）之间的FC可用性评估。= 32）。本研究表明，与PND相比，PWD的FC满意度和感知可用性更高，而PWD的有效性和效率均较低。在FC可用性评估中，结果的这种不对称模式被讨论为残疾悖论的延伸，并且可以增强对PWD进行概念化和评估HCI的理解。
