AI 中文摘要
同步常常在相互作用的人群中自发出现，对体育、物理康复和协作制造等任务有实际益处，并能增强团结和信任之感。尽管视觉交互通常被视为实现同步的主要渠道，但它受感觉运动延迟、遮挡和注意力资源限制。在此，我们测试了触觉通信能否在群体运动任务中诱导或增强同步。六个四重奏小组通过虚拟弹性带连接进行振荡性手腕屈伸，比较了仅触觉、仅视觉、触觉与视觉结合以及无反馈条件。即使微弱的触觉耦合也能诱导群体同步，触觉与视觉反馈结合比单独任何一种方式产生更高且更稳定的同步。触觉反馈还提高了群体协调频率，运动平滑度随频率上升。这些发现为协作群体环境设计触觉交互协议奠定了基础。
英文摘要
Synchronization often emerges spontaneously among interacting people, yielding practical benefits for tasks such as sports, physical rehabilitation, and collaborative manufacturing, and fostering a sense of unity and trust. Although visual interaction is typically considered the primary channel for achieving synchronization, it is constrained by sensorimotor delays, occlusions, and limited attentional resources. Here, we tested whether haptic communication can induce or enhance synchronization in a group motor task. Six quartets performed oscillatory wrist flexion/extension while being connected via virtual elastic bands; we compared haptic only, visual only, combined haptic\&visual, and no feedback conditions. Even weak haptic coupling induced group synchronization, and combining haptic with visual feedback yielded higher and more stable synchronization than either modality alone. Haptic feedback also increased the frequency at which groups coordinated, and movement smoothness rose with frequency. These findings lay the groundwork for designing haptic interaction protocols for collaborative group environments.
