Increasingly, geriatric institutions are adopting video calling services to promote social interactions between residents and their loved ones. However, a gap persists between the technologies used and the needs and abilities of older users. Interactive Televisions (iTVs) could be part of the solution as they provide a familiar and accessible way to strengthen the relationship between residents and their environment (family, friends, professionals).
User tests were conducted to evaluate the ability of older adults (OAs) from different place of living to use iTV. A total of 32 user tests were carried out with OAs living at home, in residential facilities (RFs), and in nursing homes (NHs) between November 2022 and June 2023.
The quantitative analysis revealed mixed opinions on the iTV's usability. OAs living at home tended to produce less errors and needed less help to successfully use video calling and messaging functionalities of the iTV than others. However, participants in NHs required more repetitions to benefit from a learning effect, unlike participants in RFs and at home.
This study proposed another approach to user testing, based on cognitive psychology methods. Based on the analysis of the critical stages, ergonomic recommendations were identified.
老年机构越来越多地采用视频通话服务，以促进居民与他们所爱的人之间的社交互动。然而，所使用的技术与老年用户的需求和能力之间仍然存在差距。交互式电视（iTV）可能是解决方案的一部分，因为它们提供了一种熟悉且便捷的方式来加强居民与其环境（家人、朋友、专业人员）之间的关系。
进行了用户测试，以评估来自不同居住地点的老年人使用iTV的能力。2022年11月至2023年6月期间，对居家、居住在养老机构（RF）和疗养院（NH）的老年人共进行了32次用户测试。
定量分析显示，对于iTV的可用性存在不同意见。与其他人相比，居家的老年人在成功使用iTV的视频通话和消息功能时往往出错较少，且需要的帮助也较少。然而，与养老机构和居家的参与者不同，疗养院的参与者需要更多次重复才能从学习效应中受益。
本研究基于认知心理学方法提出了另一种用户测试方法。通过对关键阶段的分析，确定了人体工程学建议。
