Measurement scales for variables.

Purpose
Smart home devices have great potential to improve the quality of life and independence of older people, positively impacting their health, safety, and comfort. However, Chinese research in this field is still in its early stages. Therefore, more comprehensive and in-depth studies are needed to comprehend the various aspects influencing the acceptance and use of smart homes by older users.
Patients and methods
This study adopted the Technology Acceptance Model (TAM) and included perceived usefulness, perceived ease of use, usage intention, intergenerational technology support, perceived value, and perceived risk as extension variables to delve deeper into the behavioral intentions of older users in smart home services. The study used a convenience sampling method to randomly distribute 236 questionnaires among older adults over the age of 60 in the school’s community and neighboring urban communities who have experience in smart home use and who can complete human-computer interactions either independently or with the help of others, mainly focusing on the four sections: user characteristics, family situation, experience of use, and usage intention. The study used structural equation modeling (SEM) and factor analysis to analyze the completion of questionnaires. Finally, we conducted a validation analysis of the rationality and scientificity of the model and derived the six dimensions of the model of the influencing factors on the use of smart home products by the elderly and the weight sizes of their corresponding 13 influencing factors.
Results
The results show that perceived usefulness and perceived ease of use have a positive effect on users’ intention to use smart homes. Perceived ease of use has a positive effect on the perceived usefulness of smart homes. In addition, intergenerational technology support, perceived value, and perceived risk impact users’ perceived usefulness and perceived ease of use of the smart home.
Conclusion
This research aims to describe the factors influencing older users’ willingness to use smart homes. The findings are not only significant for the elderly in China but also of broad value to other regions and countries facing similar demographic challenges. The development of smart homes not only involves the elderly but is also closely related to all segments of society. The government should increase policy support and guide more social forces to participate in the development of the smart home industry. Service providers and designers should fully understand the demand situation and user experience of target users to develop easy-to-use smart home solutions. At the same time, smart homes, as intelligent products for the elderly, need to focus not only on the basic needs of the elderly such as material life and home safety, but also on the spiritual needs of elderly users. Children or caregivers should always pay attention to the psychological state of the elderly and actively guide them to use smart homes to help them realize their self-worth. We look forward to more research focusing on this area in the future and further exploring the specific issues and solutions involved.

研究背景（Purpose）
智能家庭设备（smart home devices）具备极大潜力，可提升老年人群的生活质量与自主能力，对其健康、安全与舒适体验产生积极影响。然而国内该领域的研究尚处于早期阶段，因此亟需开展更全面深入的研究，以厘清影响老年用户接受并使用智能家庭产品的各类维度。

研究对象与方法（Patients and methods）
本研究采用技术接受模型（Technology Acceptance Model, TAM），纳入感知有用性、感知易用性、使用意向、代际技术支持、感知价值与感知风险作为扩展变量，以深入探究老年用户使用智能家庭服务的行为意向。研究采用便利抽样法，向该校社区及周边城市社区中60岁以上、具备智能家庭使用经验且可独立或借助他人完成人机交互的老年人群随机发放236份问卷，调研内容主要涵盖用户特征、家庭状况、使用经历与使用意向四个模块。随后采用结构方程模型（Structural Equation Modeling, SEM）与因子分析对回收问卷进行数据分析，最终对模型的合理性与科学性开展验证分析，并提炼出老年用户使用智能家庭产品影响因素模型的六大维度，以及对应13项影响因素的权重大小。

研究结果（Results）
研究结果显示，感知有用性与感知易用性对老年用户使用智能家庭产品的意向具有正向影响；感知易用性对智能家庭产品的感知有用性同样具备正向作用。此外，代际技术支持、感知价值与感知风险会对老年用户的智能家庭感知有用性与感知易用性产生影响。

研究结论（Conclusion）
本研究旨在厘清影响老年用户智能家庭产品使用意愿的各类因素。研究结论不仅对中国老年群体具有重要参考价值，同时对其他面临相似人口结构挑战的地区与国家也具备广泛的借鉴意义。智能家庭产业的发展不仅关乎老年群体，更与社会各阶层紧密相连。政府应加大政策扶持力度，引导更多社会力量参与智能家庭产业发展；服务提供商与产品设计师应充分了解目标用户的需求状况与使用体验，开发易用性更强的智能家庭解决方案。同时，面向老年群体的智能家庭产品，不仅需满足老年用户物质生活与居家安全等基础需求，还应兼顾其精神层面的需求。子女或照料者应时刻关注老年群体的心理状态，积极引导其使用智能家庭产品，助力老年用户实现自我价值。我们期待未来有更多聚焦该领域的研究，进一步探索其中涉及的具体问题与解决方案。
