视觉反馈对虚拟手离体体现的影响
Impact of Visuomotor Feedback on the Embodiment of Virtual Hands Detached from the Body
摘要：
已经表明，仅仅观察身体的不连续性会导致身体所有权的减少。然而，身体不连续性的影响主要是在参与者从第一人称视角观察并置静态虚拟身体的条件下研究的。本研究探讨了身体的不连续性对体现感的影响，当一个真实的和一个人造的虚拟身体之间建立丰富的视觉相关性。在两个实验中，我们评估了身体所有权和运动性能，当参与者在虚拟现实中使用虚拟手连接或断开连接的身体。我们发现，即使在一致的视觉反馈的存在下，仅仅观察身体的不连续性导致减少的实施。矛盾的证据被发现在运动性能，需要进一步的研究，以了解在运动任务中的视觉身体不连续性的作用。对威胁的生理反应的初步研究结果也进行了评估，表明身体视觉不连续性不会对威胁相关的皮肤电导反应产生不同的影响。目前的结果是根据过去的证据表明，身体的不连续性产生负面影响的实施。然而，需要进一步的研究来了解视觉反馈和身体形态一致性对运动性能和威胁相关的生理反应的影响。
英文摘要：
It has been shown that mere observation of body discontinuity leads to diminished body ownership. However, the impact of body discontinuity has mainly been investigated in conditions where participants observe a collocated static virtual body from a first-person perspective. This study explores the influence of body discountinuity on the sense of embodiment, when rich visuomotor correlations between a real and an artificial virtual body are established. In two experiments, we evaluated body ownership and motor performance, when participants interacted in virtual reality either using virtual hands connected or disconnected from a body. We found that even under the presence of congruent visuomotor feedback, mere observation of body discontinuity resulted in diminished embodiment. Contradictory evidence was found in relation to motor performance, where further research is needed to understand the role of visual body discontinuity in motor tasks. Preliminary findings on physiological reactions to a threat were also assessed, indicating that body visual discontinuity does not differently impact threat-related skin conductance responses. The present results are in accordance with past evidence showing that body discontinuity negatively impacts embodiment. However, further research is needed to understand the influence of visuomotor feedback and body morphological congruency on motor performance and threat-related physiological reactions.
