Smart home automation provides residents with relief and convenience in everyday life and allows for self-determined aging in place. Yet, market penetration is offset by user concerns related to privacy and trust issues: With increasing system complexity, users may perceive a loss of control and fear technical unreliability. While barriers to acceptance in terms of privacy and trust are well understood when considered separately, they are hardly investigated in conjunction so far. We conducted a quantitative study using Adaptive Choice-Based Conjoint Analysis via an online questionnaire. We explored how aspects of privacy and trust determine the willingness to use smart homes from the perspective of (future) users (n = 137, 18 to 64 years of age), and also with respect to the level of automation and application field. Results show that semi-automated systems are rather preferred than fully automated smart home technology. The perceived reliability of automation is the most important acceptance determinant, followed by the location of data storage. Whereas the awareness to use (e.g., recommendations), the type of data, and application field are less important factors for the overall willingness to use smart homes. Findings inform scientists in the field of human-automation interaction and technical developers of smart home automation for technology innovation adapted to user needs.

智能家居自动化为居民的日常生活提供了安心和便利，并允许自行决定就地老龄化。然而，市场渗透被用户对隐私和信任问题的担忧所抵消：随着系统复杂性的增加，用户可能会感到失去控制并担心技术不可靠性。虽然单独考虑隐私和信任方面的障碍是很容易理解的，但到目前为止，它们几乎没有被结合起来研究。我们通过在线问卷使用基于自适应选择的联合分析进行了定量研究。我们从（未来）用户（n = 137，18 至 64 岁）的角度，以及自动化和应用领域的水平，探讨了隐私和信任方面如何决定使用智能家居的意愿。结果表明，半自动化系统比全自动智能家居技术更受欢迎。自动化的感知可靠性是最重要的接受决定因素，其次是数据存储的位置。而使用意识（例如，推荐）、数据类型和应用领域对于使用智能家居的整体意愿而言不是那么重要的因素。研究结果为人机交互领域的科学家和智能家居自动化的技术开发人员提供了适应用户需求的技术创新。和应用领域是影响智能家居整体使用意愿的次要因素。研究结果为人机交互领域的科学家和智能家居自动化的技术开发人员提供了适应用户需求的技术创新。和应用领域是影响智能家居整体使用意愿的次要因素。研究结果为人机交互领域的科学家和智能家居自动化的技术开发人员提供了适应用户需求的技术创新。
