| 目的 为了进一步提高虚拟界面的交互高效性，设计实验探究不同元素的尺寸、扩展比和位置对虚拟远程移动交互的可用性影响。方法 基于HTC Vive平台结合第4代虚幻引擎（Unreal Engine 4）构建实验环境，选取十八名有VR设备使用经验的被试，测试了六种尺寸、三种扩展比和二十五个区域位置的可用性，并对实验结果进行方差分析。结果 选择相关性系数大于0.8的十六组有效数据，得到如下结果：目标尺寸为270 mm时在任务完成时间、指向误差和指向便携性表现最好；扩展比越大越好，尤其是当目标尺寸小于360 mm时；界面中心和左侧位置优于其他区域位置，更适合放置主要交互元素或强调元素。结论 实验搭建的虚拟现实系统及相关结论可为后续虚拟界面的设计提供客观科学的指导性建议，对提高虚拟界面交互的可用性有重要影响。 |

| Abstract: |
| The work aims to further improve the interaction efficiency of the virtual interface and design experiments to explore the effects of different element sizes, expansion ratios and locations on the usability of virtual remote mobile interaction. The experimental environment was constructed based on HTC Vive platform and Unreal Engine 4. 18 subjects with VR equipment experience were selected to test the usability of 6 sizes, 3 expansion ratios and 25 regional locations, and the variance analysis of the experimental results was carried out. The results were as follows: when the target size was 270 mm, the task completion time, pointing error and pointing portability were the best. The larger the expansion ratio, the better, especially when the target size was less than 360 mm. The center and left side of the interface were better than the rest of the area, making it more suitable for placing primary interaction elements or emphasis elements. The virtual reality system built in this experiment and the related conclusions herein can provide objective and scientific guidance for the design of the subsequent virtual interface, and have an important impact on improving the usability of the virtual interface interaction. |
