摘　　要：针对现有虚拟课堂交互性不足的问题,设计并实现了基于Unity和Leap Motion的虚拟课堂系统。基于Unity构建不同的虚拟场景,实现了场景漫游和交互功能;设计了合理的UI交互界面,引导学生自主学习,从而极大地调动了学生学习的主动性;基于Leap Motion和深度学习算法开发手势交互功能,将手势识别加入到虚拟课堂当中,丰富了交互体验,有效提高了课堂沉浸感和参与感。经调研,系统能够有效解决现有虚拟课堂存在的问题,从而提高学习效率和学习趣味性,同时具有较好的交互体验感。Aiming at the problem of insufficient interactivity of existing virtual classrooms,a virtual classroom system based on Unity and Leap Motion is designed and implemented.By building different virtual scenes based on Unity,scene roaming and in⁃teraction functions are realized.A reasonable UI interface is designed to guide students to learn independently,thus greatly mobiliz⁃ing students'initiative in learning.Gesture interaction is developed based on Leap Motion and deep learning algorithms function,gesture recognition is added to the virtual classroom,thus enriching the interactive experience,and effectively improving the sense of immersion and participation in the classroom.After investigation,the system can effectively solve the problems existing in the ex⁃isting virtual classroom,thereby improving the learning efficiency and learning interest,and at the same time,it has a better sense of interactive experience.
