3D手势计算支持的教学应用研究

摘要

3D gesture computing extends the human-computer interaction from 2D to 3D , which promotes the free interaction between the user and the virtual object , also provides a new learning process experience for learners. This article first shows the de-velopment of 3D gesture computing technology , elaborates the characteristic of this technology and the theory basic for its educational application, then analyzes the educational support process and practical effect by four cases in the aspects of reading , language, sci-ence and skills training. The research shows that the gesture or body behavior which 3D gesture computing supports would promote students’ understanding of complex knowledge and enhance their learning interest.%3D手势计算将人机交互从二维扩展到三维，促进了用户与虚拟对象的自由交互，能够为学习者提供新型的学习过程体验。在阐述3D手势计算的三维化、自由化以及视觉化特征的基础上，分析学习者身体行为对于大脑学习的影响，探索3D手势计算应用于教育的理论基础。同时，通过进一步剖析该技术在阅读、外语、科学和技能训练四个方面的教学应用典型案例，论证了3D手势计算对于教育教学过程的支持以及实践效果。研究表明，3D手势计算所支持的学习者手势乃至身体行为，能够有效促进学生对于复杂知识的理解，激发学生的学习兴趣。
