为了帮助本科生可视化应力，变形和极限状态，为每种钢连接类型，我们设计和开发了一个增强现实（AR）的交互式学习环境，其中全息图像说明连接行为覆盖在物理模型的48钢连接类型。48种连接类型的物理模型是通过3D打印先前开发的钢雕塑虚拟模型来制作的。学生在连接处施加力，观察连接处的应力、变形（如偏转、旋转和曲率）以及极限状态-所有这些都无需鼠标、操纵杆、智能手机或平板设备。对本科生的初步研究结果支持AR环境的可用性和实用性。
To help undergraduate students visualize stresses, deformation, and limit states for each steel connection type we have designed and developed an augmented reality (AR) interactive learning environment in which holographic images illustrating the connection behavior are overlaid on physical models of the 48 steel connection types. The physical models of the 48 connection types were produced by 3D printing a previously developed virtual model of the steel sculpture. Students apply forces to the connections, and observe the stresses in the connection, the deformations such as deflections, rotation, and curvatures, and the limit states–all without a mouse, joystick, smartphone or tablet device. Findings from an initial study with undergraduate students support the usability and usefulness of the AR environment.
