ABSTRACT

As technology is advancing, a great number of people with disabilities try out and adopt various mainstream and assistive technologies. However, there has been less attention paid to older adults with visual disabilities, leading to poor user experience and technology abandonment. A convenience sample of 20 older adults with visual disabilities (visual acuity ranging from 20/70 to blind with no light perception at all; duration of vision loss, 28.35 ± 23.04 years; age, 72.85 ± 7.96 years) participated in semi-structured interviews and shared their experiences with technology adoption and abandonment. The diffusion of innovation theory helped to obtain a deep understanding of how older users with visual disabilities adopt or decline technologies, various characteristics of which were discussed through relative advantage, compatibility, observability, trialability, and complexity. The relative advantage was further analyzed for usability, safety, and accessibility, and the usability aspect was broken down into more details: effectiveness, efficiency, and satisfaction. This study sheds light on the detailed characteristics that would ultimately contribute to designing, developing, and implementing future innovative technologies that meet the needs of the aging populations with visual disabilities.

摘要

随着技术的发展，许多残疾人正在尝试并采用各种主流和辅助技术。但是，对视力障碍的老年人的关注较少，导致不良的用户体验和技术放弃。便利样本包括20位视力障碍的老年人（视力范围从20/70到完全没有光明的盲人；视力丧失的持续时间为28.35±23.04岁；年龄为72.85±7.96岁）参加了半结构访谈并分享了他们在技术采用和放弃方面的经验。创新理论的传播有助于深入了解有视觉障碍的老年用户如何采用或拒绝使用技术，并通过相对优势，兼容性，可观察性，可试用性和复杂性。进一步分析了相对优势的可用性，安全性和可访问性，并且可用性方面细分为更多细节：有效性，效率和满意度。这项研究揭示了详细的特征，这些特征最终将有助于设计，开发和实施未来的创新技术，以满足视力衰老人口的需求。
