虚拟场景中图形化交互组件的深度冲突缓解研究

Research on depth conflict reduction of graphical interactive components in virtual scenes

虚拟场景要求有更自然的交互范式以满足用户需求,图形化范式可作为自然范式的有效补充,目前对图形化范式在虚拟空间中的应用研究较少,在应用时,图形化范式与虚拟场景中的主体物可能存在深度冲突。本文提出一种新的交互范式——SOMRM范式,并以虚拟现实(VR)找不同和增强现实(AR)俄罗斯方块场景为例,对添加光圈模糊和调节组件与被试间距离2种缓解虚拟场景中深度冲突的方式进行了研究。通过分析被试在虚拟场景中执行查看、抓取、滑动等交互任务所需的时间和偏差等数据,从易学性、准确性、易用性、真实性、舒适性等6个维度上比较了2种深度冲突缓解方式。研究结果表明,添加光圈模糊能较好缓解虚拟场景交互中的深度冲突。

The development of virtual scene requires a more natural paradigm to meet the needs of users,and the graphical paradigm can be an effective supplement to the natural paradigm.At present,there is little research on the use of graphical paradigm in virtual space,and there is still a depth conflict between the graphical interactive components and the subject of the scene in the application of virtual scene.This article proposes a new interactive paradigm ie.SOMRM paradigm,and takes virtual reality(VR)finding difference scene and augmented reality(AR)Tetris scene as examples.It studies two methods of reducing the depth conflict in virtual scenes by halo blur and changing the distance between components and participants.The accuracy and ease of two methods are compared by analyzing the data of time and deviation needed by the participants to perform interactive tasks such as viewing,grasping and sliding in the virtual scene.The results show that adding halo blur is a better way to reduce the depth conflict in virtual scene.
