摘要

我们的触觉在物理协作中起着至关重要的作用,然而在协作扩展现实(XR)中呈现逼真的触觉反馈仍然是一个挑战。协同定位的XR系统主要依赖于预制的被动道具,提供高保真的交互,但适应性有限。触觉错觉(HIs)利用多感官整合,已被证明在单用户环境中扩展触觉体验是有效的。然而,它们在XR协作中的作用尚未得到探讨。为了检验HIs在多用户场景中的适用性,我们进行了一项实验用户研究(N=30),调查了它们对虚拟现实中协作对象移交任务的影响。我们分别处理视觉形状和大小,并分析它们对用户性能、体验和行为的影响。结果表明,当参与者通过改变感官依赖和采用特定的感觉运动策略来适应错觉时,视触觉不匹配会降低他们的表现和体验。此外,不对称用户角色中不匹配的可视化会对性能产生负面影响。根据这些发现,我们提供了将HIs纳入协作XR的实用指南,标志着在共享虚拟空间中实现更丰富的触觉交互的第一步。

Investigating the Effects of Haptic Illusions in Collaborative Virtual Reality.

Our sense of touch plays a crucial role in physical collaboration, yet rendering realistic haptic feedback in collaborative extended reality (XR) remains a challenge. Co-located XR systems predominantly rely on prefabricated passive props that provide high-fidelity interaction but offer limited adaptability. Haptic Illusions (HIs), which leverage multisensory integration, have proven effective in expanding haptic experiences in single-user contexts. However, their role in XR collaboration has not been explored. To examine the applicability of HIs in multi-user scenarios, we conducted an experimental user study (N=30) investigating their effect on a collaborative object handover task in virtual reality. We manipulated visual shape and size individually and analyzed their impact on users' performance, experience, and behavior. Results show that while participants adapted to the illusions by shifting sensory reliance and employing specific sensorimotor strategies, visuo-haptic mismatches reduced both performance and experience. Moreover, mismatched visualizations in asymmetric user roles negatively impacted performance. Drawing from these findings, we provide practical guidelines for incorporating HIs into collaborative XR, marking a first step toward richer haptic interactions in shared virtual spaces.
