基于触觉反馈的沉浸式虚拟仿真实验设计

Design of Immersive Virtual Simulation Experiment Based on Haptic Feedback

针对虚拟仿真实验交互性和场景真实感不足的缺陷,基于建构主义学习理论和情景认知理论,采用双目立体显示技术构建三维沉浸式场景,结合触控笔的交互特征,设计一种沉浸式虚拟仿真资源构建方案,并在生物学野外实践虚拟仿真实验教学项目中验证该方案。结果表明:该方案简单易用、表现力强、交互体验好,可提高学习效率,激发学生的学习兴趣,满足其作为学习主体的感受。

Aiming at the shortcomings of virtual simulation experiment interaction and scene realism,based on constructivist learning theory and situational cognition theory,combined with the interactive characteristics of stylus,using binocular stereo display technology to construct three-dimensional immersive scene,an immersive virtual simulation resource construction plan was designed.The scheme was verified in the biological field practice virtual simulation experiment teaching project.The results show that the scheme is simple,easy to use,expressive,and interactive.It can improve learning efficiency,stimulate students􀆳interest in learning,and satisfy their feelings as a learning subject.
