摘要
虚拟现实(VR)电影作为沉浸式影像的关键形态,其视角自由性提升了观众对注视路径与体验节奏的自主选择可能,增强了观众的体验沉浸感。但为实现故事讲述,观众的注意力需由元素和故事线索引导,因此注视引导机制成为VR镜头语言系统构建的关键环节。为实现VR电影叙事信息的有效传达,确保观众观看过程中的生理舒适性,本文基于沉浸式VR影片《熊猫一八六九》的创作实践,依托自研界坐标·元宇宙虚实交互创作平台(MetaCore)的镜头建模与注视追踪系统,提出一套适用于VR电影制作流程的“三段式注视引导机制”,实现镜头起始、持续与衔接阶段的注视行为组织与节奏协同控制。通过设置4项工程测试指标,并结合眼动数据与观众主观反馈的实验验证表明,该机制在路径一致性、信息聚焦效率与转场舒适性等方面具有显著优化作用。该机制已在平台内完成原型封装,具备良好的创作适配性与引擎部署能力,可为VR电影镜头语言的系统化构建与注视引导机制的流程化集成提供实践范式与技术参考。
As a key form of immersive images,virtual reality(VR)film's freedom of viewing angle enhances the possibility of viewers'independent choice of gaze path and experience rhythm,and improves the audience's immersive experience.Attention of the audience needs to be guided by elements and story clues to complete the narrative,so the gaze guidance mechanism becomes the key step in the construction of VR films'shot language system.In order to effectively convey the narrative information of VR film and make the audience feel comfortable,this study proposes a three⁃phase gaze guidance mechanism tailored for VR film production,developed through the creation of the VR film Searching For Pandas using MetaCore,the self⁃developed virtual⁃real interaction creation platform.The mechanism coordinates gaze behavior across the initialization,progression,and transition phases of VR shots,aiming at improving information focus,rhythm continuity,and transition comfort.Four evaluation metrics were designed,combining eye⁃tracking data with subjective audience feedback.Results show that the mechanism significantly enhances path consistency,focus efficiency,and transition smoothness.The structure has been prototyped and integrated within MetaCore,demonstrating strong workflow adaptability and deployability,and offering a practical reference for the systematic construction of VR film's shot language and gaze⁃guidance integration.
