支持多通道交互的虚拟实验平台

Virtual Experiment Platform Supporting Multi-Channel Interaction

为解决现有的虚拟实验存在交互形式单一、设备昂贵、沉浸感不足等问题,提出多通道交互的虚拟实验平台。该平台借助增强现实技术实现并支持手势交互、温感与嗅觉多感知通道呈现。围绕平台的结构设计、手势交互的实现以及多感知通道呈现方面三个方面进行阐述。最后,通过两个虚拟实验对平台的易用性与实用性进行验证。结果表明平台交互自然,真实感强,能帮助学生掌握实验知识。

In order to solve the problems of single interactive form,expensive equipment and insufficient immersion in the existing vir⁃tual experiments,a multi-channel interactive virtual experiment platform is proposed.The platform uses augmented reality technology to realize and support gesture interaction,temperature and smell multi-sensing channel presentation.It focuses on three aspects:the structural design of the platform,the realization of gesture interaction,and the presentation of multi-sensing channels.Finally,the ease of use and practicability of the platform are verified through two virtual experiments.The results show that the platform has natural in⁃teraction and strong sense of reality,which can help students master experimental knowledge.
