摘要/Abstract

摘要： 由于沉浸式环境下的三维交互方式对二维界面操作不够友好，使得依赖于二维列表界面的流场数据管理任务变得复杂且低效。为了实现沉浸式虚拟环境下对流场数据高效的组织和管理，增强用户对流场空间信息的理解，提出一种基于多视图结合交互的沉浸式流场可视化数据块管理方法。该方法构建了一个三维小视图用于提供场景概览，并通过“主视图交互+小视图辅助”“小视图交互+主视图反馈”等多种多视图组合交互方式完成对多块流场数据的管理交互操作。最后构建了一个基于手势的沉浸式流场可视化系统，定义多项交互任务，从学习时长、完成时间和用户反馈几个方面对比了多视图方法和传统交互方法差异。实验结果表明，相比于传统交互方法，多视图方法可以显著提高数据管理任务的效率。

Abstract: Because the three-dimensional immersive environment is not friendly enough for two-dimensional interface operation, the flow field data management task based on two-dimensional list interface becomes complex and inefficient. In order to achieve efficient organization and management of flow field data in an immersive virtual environment and enhance users’ understanding of flow field spatial information, an immersive flow field visualization data block management method based on multi-view combined interaction is proposed. This method constructs a three-dimensional small view to provide an overview of the scene, and completes the management and interactive operation of multi-block flow field data through multi-view combination interaction modes such as “main view interaction and small view assistance” “small view interaction and main view feedback”, etc. Finally, a gesture-based immersive flow field visualization system is constructed, and multiple interactive tasks are defined. The differences between the multi-view method and the traditional interactive method are compared in terms of learning time, completion time and user feedback. Experimental results show that compared with traditional interactive methods, multi-view method can significantly improve the efficiency of data management tasks.
