研究虚拟协作中形象呈现如何影响触觉互动的社交沉浸感。
Exploring Remote Collaborative Tasks: The Impact of Avatar Representation on Dyadic Haptic Interactions in Shared Virtual Environments
- 对比四种形象显示条件，探究视觉与触觉融合对协作的影响。
- 伙伴形象显示显著提升社交沉浸感，但不影响任务表现。
- 触觉反馈已足够支撑任务执行，适合远程协作系统设计。
本研究首次探讨了共享虚拟环境（SVEs）中触觉交互与角色形象呈现之间的相互作用。通过一系列实验，参与者在四种角色形象条件下进行双人协作任务：双方形象均显示、仅显示自身形象、仅显示对方形象、均不显示形象。结果表明，特别是对合作对象的形象呈现，能显著增强用户的社交沉浸感，而仅靠触觉交互无法完全实现此效果。然而，形象的存在与否或类型均未影响任务表现或参与者施力程度，说明触觉交互已提供足够的操作提示以完成任务。研究强调，在虚拟协作中需融合视觉与触觉模态，以优化沟通体验并增强社交沉浸感。
原文摘要 · Abstract (English)
This study is the first to explore the interplay between haptic interaction and avatar representation in Shared Virtual Environments (SVEs). Specifically, how these factors shape users' sense of social presence during dyadic collaborations, while assessing potential effects on task performance. In a series of experiments, participants performed the collaborative task with haptic interaction under four avatar representation conditions: avatars of both participant and partner were displayed, only the participant's avatar was displayed, only the partner's avatar was displayed, and no avatars were displayed. The study finds that avatar representation, especially of the partner, significantly enhances the perception of social presence, which haptic interaction alone does not fully achieve. However, neither the presence nor the type of avatar representation impacts the task performance or participants' force effort of the task, suggesting that haptic interaction provides sufficient interaction cues for the execution of the task. These results underscore the significance of integrating both visual and haptic modalities to optimize remote collaboration experiences in virtual environments, ensuring effective communication and a strong sense of social presence.
