Abstract

Introduction: Incorporating an additional limb that synchronizes with multiple body parts enables the user to achieve high task accuracy and smooth movement. In this case, the visual appearance of the wearable robotic limb contributes to the sense of embodiment. Additionally, the user’s motor function changes as a result of this embodiment. However, it remains unclear how users perceive the attribution of the wearable robotic limb within the context of multiple body parts (perceptual attribution), and the impact of visual similarity in this context remains unknown. Methods: This study investigated the perceptual attribution of a virtual robotic limb by examining proprioceptive drift and the bias of visual similarity under the conditions of single body part (synchronizing with hand or foot motion only) and multiple body parts (synchronizing with average motion of hand and foot). Participants in the conducted experiment engaged in a point-to-point task using a virtual robotic limb that synchronizes with their hand and foot motions simultaneously. Furthermore, the visual appearance of the end-effector was altered to explore the influence of visual similarity. Results: The experiment revealed that only the participants’ proprioception of their foot aligned with the virtual robotic limb, while the frequency of error correction during the point-to-point task did not change across conditions. Conversely, subjective illusions of embodiment occurred for both the hand and foot. In this case, the visual appearance of the robotic limbs contributed to the correlations between hand and foot proprioceptive drift and subjective embodiment illusion, respectively. Discussion: These results suggest that proprioception is specifically attributed to the foot through motion synchronization, whereas subjective perceptions are attributed to both the hand and foot.

虚拟机器人肢体与手足同步的感知归因研究
介绍:结合一个额外的肢体,与多个身体部位同步,使用户能够实现高任务精度和平稳运动。在这种情况下,可穿戴机器人肢体的视觉外观有助于体现感。此外,用户的运动功能也会因该实施例而改变。然而,目前尚不清楚用户如何在多个身体部位的背景下感知可穿戴机器人肢体的归属(感知归属),并且在这种情况下视觉相似性的影响仍然未知。方法:采用本体感觉漂移和视觉相似性偏差的方法,研究了单个肢体(仅与手足运动同步)和多个肢体(与手足平均运动同步)条件下虚拟机械肢体的感知归因。实验参与者使用虚拟机械臂进行点对点任务,该机械臂与他们的手和脚同时同步运动。此外,还改变了末端执行器的视觉外观,以探讨视觉相似性的影响。结果:实验显示,只有参与者的足部本体感觉与虚拟机器人肢体一致,而点对点任务的纠错频率在不同条件下没有变化。相反,手和脚都出现了主观的具体化错觉。在这种情况下,机械肢体的视觉外观分别对手和脚本体感觉漂移和主观体现错觉的相关性做出了贡献。讨论:这些结果表明,本体感觉通过运动同步特别归因于足部,而主观知觉归因于手和脚。
