中文摘要:

      目的 用户在复杂环境下的虚拟村寨中游览，为了兼顾用户游览体验满意度及用户行为偏好，提出了基于用户体验满意度的路径规划方法。方法 首先，还原真实村寨的虚拟场景，对虚拟村寨进行降维处理，获取栅格化地图;然后，提出一种改进A星算法，并以地标点、用户移动轨迹、用户喜爱度等为约束条件，构建多因素影响下的虚拟村寨路径规划模型;最后，通过设计实验采集用户行为偏好数据，并由所构建模型开展约束影响权重分析，并将约束条件作为开展寻路算法的影响因素。结果 实验结果表明，该方法所规划出的路径能够有效兼容地标点、用户移动轨迹、用户喜爱度等多种约束条件。结论 路径规划结果对提升用户在虚拟村寨场景中的体验满意度具有明显优越性，能为用户沉浸式游览体验设计提供新方法。

英文摘要:

      The work aims to propose a path planning method based on user experience satisfaction, in order to take into account user satisfaction and user behavior preferences when users visit virtual villages in a complex environment. Firstly, the virtual scene of the real village was restored, and the virtual village was subject to dimensionality reduction processing to obtain a rasterized map. Then, an improved A-star algorithm was proposed, and landmark points, user movement trajectories and user preference were used as constraints to build a virtual village path planning model under the influence of multiple factors. Finally, user behavior preference data were collected through design experiments, the constraint impact weight analysis was carried out by the constructed model, and the constraint conditions were used as the influencing factors of path finding algorithm. The experimental results showed that the path planned by this method could effectively accommodate multiple constraints such as landmarks, user movement trajectories, and user preference. The path planning results have obvious advantages in improving the user experience satisfaction in the virtual village scene, and can provide a new method for the user's immersive tour experience design.
