The rapid evolution of augmented reality (AR) technology has presented new opportunities in the domain of education. Acting as a bridge between the virtual and real worlds, AR technology overcomes the physical limitations of our classrooms at a low cost and provides an interactive learning experience. In this study, we present a smartphone AR application, named the AR-E-Helper, which assists the learning of students in higher education lectures. Our goal is to provide an AR-enhanced learning experience for students. To validate the effectiveness of the AR-E-Helper, we conducted an experiment that compares three classes: AR-enhanced, smartphone-enhanced, and nontechnology-enhanced classes. Through the experiment, we observed that our application was helpful in maintaining student's focus in class, promoting their interest, and increasing their satisfaction. Furthermore, we also found how to improve our application based on the observations that the application brought some downsides to the learning activities. We expect that this study will be helpful to design AR learning tools in the future.

课堂互动学习：用于学习的移动增强现实辅助应用程序

增强现实 (AR) 技术的快速发展为教育领域带来了新机遇。作为虚拟世界和现实世界之间的桥梁，AR 技术以低成本克服了我们教室的物理限制，并提供了交互式学习体验。在这项研究中，我们提出了一个名为 AR-E-Helper 的智能手机 AR 应用程序，它可以帮助学生在高等教育讲座中学习。我们的目标是为学生提供增强现实的学习体验。为了验证 AR-E-Helper 的有效性，我们进行了一项实验，比较了三个类：AR 增强类、智能手机增强类和非技术增强类。通过实验，我们观察到我们的应用程序有助于保持学生在课堂上的注意力，促进他们的兴趣，并提高他们的满意度。此外，我们还发现了如何根据应用程序给学习活动带来一些缺点的观察来改进我们的应用程序。我们希望这项研究有助于未来设计 AR 学习工具。
