摘要:

针对传统虚拟实验存在的开发效率低、体验单一等问题,提出多感知通道融合虚拟实验的可视化快速生成方法。对虚拟实验的实验步骤、实验步骤序列进行定义。提出基于Petri网的实验元素参数化描述方法对实验步骤序列进行描述,突破传统虚拟实验一步步按既定程序走的约束,支持建立探究式虚拟实验。提出路由图的可视化表达方法及其与Petri网之间的转换方法,使用户能通过编辑路由图的方式实现实验的快速开发,融入了嗅觉与温感两个通道的反馈,使实现视、听、嗅、触多感知通道融合的虚拟实现成为可能。为验证所提出的方法,开发了相应的原型系统,并以铝热反应实验为例,介绍生成过程。结果表明:该可视化快速编辑方法对虚拟实验的编辑有效且可行。

Abstract:

Aiming at the low development efficiency and single experience in traditional virtual experiments, a rapid generation method of multi-sensing channel fusion virtual experiment visualization is proposed. The experimental steps and sequence of experimental steps of the virtual experiment are defined. A parameterized description method of experimental elements based on Petri net is proposed to describe the sequence of experimental steps, which breaks through the constraints the established procedure steps of traditional virtual experiments and supports the exploratory virtual experiments. The visual expression method of the routing graph and the conversion method between the routing graph and the Petri net are proposed, in which users can quickly edit the sequence of experimental steps by editing the routing graph. The feedbacks of the two channels of smell and temperature are incorporated, to realize the virtual realization of the fusion of multi-sensing channels of sight, hearing, smell and touch. To verify the proposed method, a prototype system is developed, and the thermite reaction experiment is taken as an example to introduce the generation process. The results show that the visual rapid editing method is effective and feasible for the editing of virtual experiments.
