基于学习分析技术的手势计算教学应用

Application of Gesture Computing Teaching Based on Learning Analytics Technology

学习分析技术已经广泛运用于课堂教学各个层面,手势计算紧密联系实践教学环节。运用学习分析技术,准确把握学习者的学习状态,搭建了基于Kinect的3D手势计算环境,对人手的复杂运动形态进行捕捉、分割、追踪与识别,并与实际进行对比验证。阐述了3D手势计算的内涵与特征,论证了其应用于教育的理论与实践基础,为进一步改进课堂教学策略,推动理论知识与教学实践相融合提出了建议。

Current,learning analytics technology has been widely used in all aspects of classroom teaching.Gestures computing is closely connected with teaching links.First of all,this paper expounds the connotation and characteristics of 3 Dgesture to computing and demonstrates its application in the education theory and practice.By the application of the learning analytics technology to accurately grasp the status in the field of learning,we set up a computing environment based on the 3 Dgesture from Kinect to capture,segmentate,track and identify the complex movement forms of a man＇s hand,and the actual results were compared with reality.The strategies of how to further improve classroom teaching are also proposed to promote integration of theory with teaching practice.
