The development of the Internet of Things (IoT) came with the manufacturing of a huge amount of smart things equipped with sensors for making them aware of their environment, and with network connection for allowing remote interaction with them. However, most smart things still lack enough autonomy and context-awareness, hindering them from being people-friendly and actually useful for their users' everyday tasks. IoT devices should take advantage of their sensors and smartness to react automatically to the needs of their users and to provide seamless interactions with them. Within this field, the authors work on the design of Digital Avatars, a mobile computing framework for dynamically programming interactions among smart devices. The framework is based on the virtual profile of the user, which is inferred, stored, and shared by their smartphone. The profile provides a personalized context for running scripts which interact with IoT devices. This way, smartphones become a digital avatar of the user, capable of acting as a personal and seamless interface with their IoT environment. In this work, we present a formalization of Digital Avatars by means of a Linda-based approach with multiple shared tuple spaces. By means of a case study, we show how properties of the systems can be proved, and we briefly describe an implementation of both the Digital Avatars framework and the case study.

物联网（IoT）的发展伴随着大量智能物品的制造，这些物品配备有传感器以使其了解环境，并具有网络连接以允许与其进行远程交互。但是，大多数智能事物仍然缺乏足够的自主权和上下文感知能力，这妨碍了它们变得对人友好，并且实际上对于用户的日常工作很有用。物联网设备应利用其传感器和智能来自动响应用户需求，并提供与它们的无缝交互。在这一领域，作者致力于数字化身的设计，数字化身是一种用于动态编程智能设备之间交互的移动计算框架。该框架基于用户的虚拟配置文件，该虚拟配置文件被推断，存储，并由他们的智能手机共享。该配置文件为运行与IoT设备交互的脚本提供了个性化的上下文。通过这种方式，智能手机成为用户的数字化身，能够充当与其物联网环境的个人无缝接口。在这项工作中，我们通过具有多个共享元组空间的基于Linda的方法，提出了数字化身的形式化。通过案例研究，我们展示了如何证明系统的特性，并简要描述了数字头像框架和案例研究的实现。我们通过具有多个共享元组空间的基于Linda的方法，提出了数字化身的形式化。通过案例研究，我们展示了如何证明系统的特性，并简要描述了数字头像框架和案例研究的实现。我们通过具有多个共享元组空间的基于Linda的方法，提出了数字化身的形式化。通过案例研究，我们展示了如何证明系统的属性，并简要描述了数字头像框架和案例研究的实现。
