手跟踪和触觉作为虚拟现实（VR）系统的关键技术越来越重要。为了设计这样的系统，了解虚拟手的外观如何影响用户体验以及人脑如何整合视觉和触觉是至关重要的。然而，目前尚不清楚视觉和触觉反馈的多感官整合是否会受到VR中虚拟手的影响。我们在VR中进行了一项用户研究，以深入了解手的外观对大脑如何使用线索冲突范式结合视觉和触觉信号的影响。在本文中，我们表明，检测表面的不规则性（凹凸不平和洞）的眼睛和手的感觉是由化身的手渲染的影响。然而，敏感性的变化并不与感知肢体所有权的程度。定性反馈提供了洞察潜在的视觉-触觉集成的干扰线索。
Hand tracking and haptics are gaining more importance as key technologies of virtual reality (VR) systems. For designing such systems, it is fundamental to understand how the appearance of the virtual hands influences user experience and how the human brain integrates vision and haptics. However, it is currently unknown whether multi-sensory integration of visual and haptic feedback can be influenced by the appearance of virtual hands in VR. We performed a user study in VR to gain insight into the effect of hand appearance on how the brain combines visual and haptic signals using a cue-conflict paradigm. In this paper, we show that the detection of surface irregularities (bumps and holes) sensed by eyes and hands is affected by the rendering of avatar hands. However, sensitivity changes do not correlate with the degree of perceived limb ownership. Qualitative feedback provides insights into potentially distracting cues in visual-haptic integration.
