摘要/Abstract

摘要：

针对基于二维显示交互环境的流场可视化应用由于深度信息不足导致交互效率较低的问题，引入虚拟现实技术，提出具备多样化交互方式的沉浸式流场可视化系统。该系统基于凝视与手势交互技术，设计并实现了基于用户手势的导航方法与三维交互控件，基于用户凝视与手势的沉浸式交互面板，以及基于可视化场景的沉浸式交互管理方法与基于可视化算法树的可视化网络管理方法，对用户交互进行了系统化管理，能够在沉浸式环境提供对典型流场可视化操作的全流程支持。用户实验结果表明：该系统能够在典型流场可视化场景下为用户提供高效、自然的交互。

Abstract:

Aiming at the problem of low interaction efficiency due to the lack of depth information in the current desktop flow visualization application based on the two-dimensional display interaction environment, virtual reality technology is introduced to design and implement an immersive flow visualization system with diversified interaction methods. Based on the gaze and gesture interaction technology, the system designs and implements gesture-based navigation methods and three-dimensional interactive widgets based on user requirements, as well as immersive interactive panels based on user gaze and gestures. We designed and implemented an immersive interactive management method based on visual scenes and a visual network management method based on visual algorithm trees. It systematically manages user interactions and can provide full process support for typical flow field visualization operations in immersive virtual reality environment. The experimental results show that the system can provide users with effi-cient and natural interaction under the typical flow field visualization application scenario.

Key words: immersive analytics, flow visualization, virtual reality, gesture interaction, gaze interaction
