摘要： 虚拟现实环境给三维空间场景应用带来更强的真实感和身临其境的体验。在虚拟现实场景中经 常需要使用 360全景图像生成沉浸式环境背景，其中全景流体动力学绘画系统提供了一个新的全景图绘制方 法。在调研虚拟现实技术在流体绘画领域应用的适用性测试中，本文综合运用用户测试法、操作日志分析法、 事后问卷调查法和访谈法，对基于虚拟现实的全景式流体绘画创作系统进行可用性评估，并创意性地使用可视 化方法辅助日志分析。所有的受试者均认为系统的可用性不低于一般水平，利用该系统完成流体绘画的创作工 作不需要受试者具有专业绘画经验。受试者对系统的功能效果持积极肯定的意见，并期待尝试用其他交互形式 代替手柄类交互方式以促进艺术创作的表达。其研究方法和结果将为同类系统的开发和评估提供参考。

Abstract: Immersive Virtual Environments (IVEs) bring more realistic immersion and in-person experience to 3D scenes. Besides, 360-degree panoramic images are imperative for the effective creation of immersive environment backgrounds. Panoramic Fluid Painting (PFP) introduces a novel creative tool for panoramic painting with fluid dynamics. In this paper, the applicability of virtual reality technologies was investigated in the field of fluid painting. Specifically, the user testing method, operation log analysis, post-hoc questionnaire, and interview were employed to study the usability of the PFP system in virtual reality environments. Then, the operation log was investigated to facilitate procedural analysis. All testers believe that the usability of the system was no lower than the average level, and even a novice user can use the system to complete the creation of fluid painting pieces. The users primarily held positive opinions on the function and effects of the system, insisting that such interaction methods of the handle would enhance the expression of artistic creation. The methods and results of the research would provide a reference for the development and evaluation of similar systems.
