尽管已经有许多尝试通过虚拟现实和增强现实（VR/AR）来提高学生在课堂上的参与度和互动，但结构工程仍然是缺乏互动学习的学科之一。作者早期曾尝试通过以学生为中心的网络物理系统（SCPS）来改善学生在结构分析和动力学方面的学习，该系统对学生的运动和结果结构行为做出反应。该系统使用移动设备作为传感器并发送数据以供服务器处理。因此，它受到传输控制协议/互联网协议 (TCP/IP) 固有的限制——滞后和不稳定。因此，本文提出了一种新的 SCPS 工具的开发，该工具具有新的系统架构，更加稳定并提供更好的用户体验。该 SCPS 捕获并使用学生的运动（即行走、转弯和跳跃）作为虚拟桥上的点载荷。当学生四处走动时，结构行为（即偏转）会被实时模拟和可视化。
Although there have been many attempts to increase student engagement and interaction in class through virtual reality and augmented reality (VR/AR), structural engineering has remained as one of the disciplines that lacks interactive learning. There was an earlier attempt by the authors to improve student learning in structural analysis and dynamics through a student-centric cyber-physical system (SCPS) that reacts to student movement and outcomes structural behavior. This system used mobile devices as sensors and sent data to be processed by a server. As a result, it suffered from the inherent limitation of Transmission Control Protocol/Internet Protocol (TCP/IP)—lags and instability. Therefore, this paper presents the development of a new SCPS tool with a new system architecture that is much more stable and provide better user experience. This SCPS captures and uses student movement (i.e., walking, turning, and jumping) as point loads on a virtual bridge. As students move around, structural behavior (i.e., deflection) is simulated and visualized in real time.
