Abstract

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
