在这项工作中,我们调查的影响,音频和视觉反馈对虚拟现实(VR)中的操作任务。在没有控制器的触觉反馈的情况下,使用人的手抓握虚拟对象可能导致较慢的交互,因为用户可能不清楚抓握已经发生。提供替代反馈(诸如视觉或音频提示)可以导致更快和更精确的交互,但也可能影响用户偏好和虚拟手的感知所有权。在这项研究中,我们测试四个反馈条件的虚拟抓。三个条件提供反馈时,抓住或释放发生,无论是视觉,听觉,或两者兼而有之,和一个不提供这些事件的反馈。我们分析了每个反馈条件对交互性能的影响,测量它们对虚拟手感知所有权的影响,并衡量用户偏好。在一个实验中,用户使用每个反馈条件执行拾取和放置任务。我们发现,听觉反馈的抓取是首选视觉反馈,即使它似乎降低抓取性能,并发现有很小的所有权之间的差异,我们的条件。
In this work, we investigate the influence that audio and visual feedback have on a manipulation task in virtual reality (VR). Without the tactile feedback of a controller, grasping virtual objects using one’s hands can result in slower interactions because it may be unclear to the user that a grasp has occurred. Providing alternative feedback, such as visual or audio cues, may lead to faster and more precise interactions, but might also affect user preference and perceived ownership of the virtual hands. In this study, we test four feedback conditions for virtual grasping. Three of the conditions provide feedback for when a grasp or release occurs, either visual, audio, or both, and one provides no feedback for these occurrences. We analyze the effect each feedback condition has on interaction performance, measure their effect on the perceived ownership of the virtual hands, and gauge user preference. In an experiment, users perform a pick-and-place task with each feedback condition. We found that audio feedback for grasping is preferred over visual feedback even though it seems to decrease grasping performance, and found that there were little to no differences in ownership between our conditions.
