背景：福尔斯是老年人（OA）的一个重要问题，他们中的许多人在跌倒后无法起床。简介：虽然存在许多旨在检测跌倒的器械，但很少有工作用于评估此类器械的可用性。我们提出了一个纵向可用性研究的跌倒检测（FD）设备测试与OA在现实世界中的设置。材料与方法：OAs被招募并要求使用可穿戴FD设备长达4个月。参与者在基线和2个月和4个月接受采访，并鼓励他们提供直接反馈的经验。结果：共有18名OAs参与了研究。8人完成了为期4个月的试验。我们共进行了38次访谈（16次基线，7次中点，15次最终），共记录了78条评论。虽然参与者很喜欢该设备的GPS和自动检测功能，但他们对该设备的误报量和侵扰性感到不满。许多人也没有看到拥有该设备的巨大需求，或者对该设备感到尴尬。讨论内容：工程师们必须努力更好地开发这项技术，以便听力损失、灵活性有限和视力低下的人也能使用。利用适合年龄的设计技术将有助于使这种信息学工具更方便用户使用。结论：我们探索了具有OA的特定FD设备的可用性，并提供设计建议，以帮助未来的设备制造商创建更适合年龄的设备。
Background: Falls are a significant concern for the older adult (OA) population, many of whom are unable to get up following a fall. Introduction: While many devices exist designed to detect a fall, little work has been conducted to evaluate the usability of such devices. We present a longitudinal usability study of a fall detection (FD) device tested with OAs in real-world settings. Materials andMethods: OAswere recruited and asked to use awearable FD device for up to 4 months. Participants were interviewed at baseline and 2 and 4 months and encouraged to provide direct feedback on their experience. Results: In total, 18OAs participated in the study. Eight completed the 4-month trial. We conducted a total of 38 interviews (16 baseline, 7 midpoint, and 15 final) and logged a total of 78 comments. While participants enjoyed the GPS and automatic detection features of the device, they were unhappy with the volume of false alarms and obtrusiveness of the device. Many also did not see a great need for having the device or were embarrassed by the device. Discussion: Engineers must work to better develop this technology so that it is accessible to people with hearing loss, limited dexterity, and low vision. Utilizing age-appropriate design techniques will help make such informatics tools more user friendly. Conclusion: We explored the usability of a particular FD device with OAs and provide design recommendations to help future device manufacturers create more age-appropriate devices.
