【摘要】 在虚拟现实选择交互任务中,避免因用户手部抖动和当界面平行于用户时导致对界面边缘位置上按钮选择点击时间变长、交互难度增加的问题。提出立体目标扩展交互方案,在空间维度上增加按钮点击范围。将扩展角宽度和目标角宽度作为自变量进行实验,测试方案提升效果和用户主观评价,对数据进行分析,完善交互设计方案。通过测试得出传统交互方案与不同尺寸的立体目标扩展交互方案在3种按钮尺寸下的客观完成时间和主观评价得分。立体目标扩展交互方案在选择任务完成时间和主观评价上均优于传统射线交互方案;3°为目标扩展角宽度最佳值。提出了创新的虚拟现实选择交互设计方案,有效提升了虚拟现实射线交互的效率和用户体验,对提升现阶段虚拟现实交互体验具有重要意义。更多还原

【Abstract】 In the virtual reality selection interaction task,avoid the problems of long click time and increased interaction difficulty for button selection on the interface edge position due to user hand shake and when the interface is parallel to the user.We proposed a three-dimensional target extension interaction scheme to increase the button click areas in the spatial dimension.Experiment with the extended angular width and the target angular width as independent va riables,test the effect of the scheme enhancement,and the subjective evaluation of users,analyze the data,and improve the interaction design scheme.The objective completion time and subjective evaluation scores of the traditional interaction scheme and the three-dimensional target extension intera ction scheme with different sizes were tested for the three button sizes.The three-dimensional target extension interaction scheme outperformed the traditional ray interaction scheme in terms of selection task completion time and su bjective evaluation;3°was the optimal value for the target extension angular width.An innovative interaction design scheme for virtual reality selection is proposed to effectively improve the efficiency and user experience of virtual reality ray interaction,which is of great significance to enhance the current sta ge of virtual reality interaction experience.更多还原
