背景:智能扬声器,例如亚马逊的Echo和谷歌的NestHome,将自然语言处理与对话界面相结合,以执行日常任务,喜欢播放音乐和查找信息。易于使用,他们被老年人拥抱,包括那些身体功能有限的人,愿景,或计算机知识。虽然智能扬声器越来越多地用于研究目的(例如,实施干预措施并自动记录选定的研究数据),有关使用这些设备进行与健康促进计划相关的研究的优缺点的信息有限。
目的:这项研究评估了使用智能扬声器提供旨在帮助老年人增强身体健康的身体活动(PA)计划的可行性和可接受性。
方法:社区居住的老年人(n=18)被要求使用自定义的智能扬声器应用程序参与基于证据的,低影响PA计划10周。收集的数据,包括技术验收措施,采访,字段注释,和设备日志,使用并行混合分析方法进行分析。使用时间序列方差分析评估技术接受措施,以检查可接受性,适当性,可行性,并打算采用智能音箱技术。设备日志提供了与设备和干预的交互和采用的证据。对访谈和现场笔记进行了主题编码,以对定量度量进行三角剖分,并进一步扩展与干预保真度有关的因素。
结果:智能扬声器被发现可以用于管理PA程序,因为参与者报告这些器械具有高度可用性(平均5.02,SE0.38),并且有继续使用的强烈意愿(平均5.90,SE0.39).语音用户界面和与设备在日常任务中的参与度等因素被认为对可接受性有意义。研究活动设备的可行性,然而,是混合的。尽管参与者认为智能扬声器易于使用(平均5.55,SE1.16),功能和技术因素,例如Wi-Fi连接和适当的命令措辞,需要向参与者提供额外的支持资源,并可能损害干预措施的保真度。
结论:智能扬声器为针对老年人的PA计划提供了可接受且适当的行为干预技术,但需要对资源计划的额外要求。技术支持,和故障排除,以确保它们在研究背景和干预的保真度方面的可行性。
BACKGROUND: Smart speakers, such as Amazon\'s Echo and Google\'s Nest Home, combine natural language processing with a conversational interface to carry out everyday tasks, like playing music and finding information. Easy to use, they are embraced by older adults, including those with limited physical function, vision, or computer literacy. While smart speakers are increasingly used for research purposes (eg, implementing interventions and automatically recording selected research data), information on the advantages and disadvantages of using these devices for studies related to health promotion programs is limited.
OBJECTIVE: This
study evaluates the feasibility and acceptability of using smart speakers to deliver a physical activity (PA) program designed to help older adults enhance their physical well-being.
METHODS: Community-dwelling older adults (n=18) were asked to use a custom smart speaker app to participate in an evidence-based, low-impact PA program for 10 weeks. Collected data, including measures of technology acceptance, interviews, field notes, and device logs, were analyzed using a concurrent mixed analysis approach. Technology acceptance measures were evaluated using time series ANOVAs to examine acceptability, appropriateness, feasibility, and intention to adopt smart speaker technology. Device logs provided evidence of interaction with and adoption of the device and the intervention. Interviews and field notes were thematically coded to triangulate the quantitative measures and further expand on factors relating to intervention fidelity.
RESULTS: Smart speakers were found to be acceptable for administering a PA program, as participants reported that the devices were highly usable (mean 5.02, SE 0.38) and had strong intentions to continue their use (mean 5.90, SE 0.39). Factors such as the voice-user interface and engagement with the device on everyday tasks were identified as meaningful to acceptability. The feasibility of the devices for research activity, however, was mixed. Despite the participants rating the smart speakers as easy to use (mean 5.55, SE 1.16), functional and technical factors, such as Wi-Fi connectivity and appropriate command phrasing, required the provision of additional support resources to participants and potentially impaired intervention fidelity.
CONCLUSIONS: Smart speakers present an acceptable and appropriate behavioral intervention technology for PA programs directed at older adults but entail additional requirements for resource planning, technical support, and troubleshooting to ensure their feasibility for the research context and for fidelity of the intervention.
