IoT (Internet of Things)-enabled products are increasingly used by consumers and continuously propagate in daily life. Billions of networked objects not only increase the complexity of development but also raise user interaction and adaptation to individual needs. The more non-expert users are involved in decision making, interaction, and adaptation processes, the more user-centric IoT design is crucial, particularly when the number of elderly users is steadily increasing. In this paper, we study the capabilities of adopting IoT products through user-informed adaptation in a major IoT application domain, home healthcare. We review evidence from established practice in the field on how users can be supported when aiming to adapt medical IoT (M-IoT) home applications to their needs. We examine the empirically grounded use of IoT sensors and actuators, as well as the adaptation process users adopt when using an IoT application in a personalized environment. Our analysis (technological evidence) reveals various IoT devices that have already been applied in M-IoT adaptation settings to effectively support users. Our analysis reveals that only few empirically sound findings exist on how users actually perceive interactive adaptation features and redesign M-IoT applications. Based on the analysis of these empirically grounded findings, we suggest the development of a domain-specific user-centric adaptation feature. Specifically, we exemplify a tangible adaptation device for user-informed M-IoT application in home healthcare. It has been developed prototypically and tested in an environment for personalized home healthcare.

物联网家庭医疗保健中的用户知情适应：经验证据的基础发展

支持物联网（IoT）的产品越来越多地被消费者使用，并在日常生活中不断传播。数十亿的网络对象不仅增加了开发的复杂性，而且还提高了用户交互和对个人需求的适应。参与决策、交互和适应过程的非专家用户越多，以用户为中心的物联网设计就越重要，特别是当老年用户数量稳步增加时。在本文中，我们研究了通过用户知情的适应在主要物联网应用领域（家庭医疗保健）中采用物联网产品的能力。我们回顾了该领域既定实践的证据，了解如何为用户提供支持，以适应医疗物联网 (M-IoT) 家庭应用程序以满足他们的需求。我们研究了物联网传感器和执行器的实证使用，以及用户在个性化环境中使用物联网应用程序时采用的适应过程。我们的分析（技术证据）揭示了已应用于 M-IoT 适应设置以有效支持用户的各种 IoT 设备。我们的分析表明，关于用户如何实际感知交互式适应功能和重新设计 M-IoT 应用程序，只有很少的实证合理的发现。基于对这些实证研究结果的分析，我们建议开发特定领域的以用户为中心的适应功能。具体来说，我们举例说明了一种用于家庭医疗保健中用户知情的 M-IoT 应用的有形适应设备。它是在个性化家庭医疗保健环境中进行原型开发和测试的。
