Smartphones have become highly personalized interfaces between people and the technology ecosystem around them. In this sense, they play a key role for a technology shift from the current Internet of Things to a future human-centric paradigm of an Internet of People, automatically adapting smart things and services to the preferences and context of their users. In this paper, we propose the use of Complex Event Processing (CEP) engines deployed in the users’ smartphones granting them context-awareness capabilities in order to react to external stimulus, and enabling them to interact both with smart things and services in the surroundings of the users. With that purpose, we have designed a communication architecture that interconnects CEP engines running on smartphones, providing a framework for building applications for Mobile-based Collaborative Social Computing (MCSC). For that, we make use of previous works of the authors with Digital Avatars, a framework which promotes the use of smartphones for inferring and sharing a unique digital avatar or virtual profile of each user. The resulting framework, which we have called Collaborative CEP, allows to implement complex interactions among users, and between them and the IoT, a common need in Collaborative Social Computing applications. We provide a proof of concept based on the implementation of a Cops and Robbers game to test the expressiveness and correct functioning of the framework, and we evaluate its performance and efficiency.

智能手机已成为人们与其周围技术生态系统之间高度个性化的界面。从这个意义上说，它们在从当前的物联网到未来以人为中心的人联网范式的技术转变中发挥着关键作用，自动使智能事物和服务适应用户的偏好和环境。在本文中，我们建议使用部署在用户智能手机中的复杂事件处理（CEP）引擎，赋予他们上下文感知能力，以便对外部刺激做出反应，并使他们能够与周围的智能事物和服务进行交互用户的。为此，我们设计了一种通信架构，可互连智能手机上运行的 CEP 引擎，为构建基于移动的协作社交计算 (MCSC) 应用程序提供框架。为此，我们利用了作者之前的数字化身作品，这是一个促进使用智能手机来推断和共享每个用户的独特数字化身或虚拟个人资料的框架。由此产生的框架，我们称之为协作 CEP，允许在用户之间以及用户与物联网之间实现复杂的交互，这是协作社交计算应用程序中的常见需求。我们提供了基于警察与强盗游戏的实现的概念验证，以测试框架的表现力和正确功能，并评估其性能和效率。
