研究皮肤拉伸感知的干扰效应，为可穿戴设备设计提供依据。
Exploring Interference between Concurrent Skin Stretches
- 通过30人实验，测试双通道同时拉伸对感知的影响。
- 同位置拉伸时感知性能下降，但主观负荷不变。
- 提醒多通道设备避免模块近距离布置。
本研究探讨了并发皮肤拉伸刺激对本体感觉感知的干扰效应。基于30名参与者的人体实验，结果表明：当多个皮肤拉伸信号同时作用于相邻区域时，会出现掩蔽效应，显著降低感知准确性；然而被试的主观工作负荷并未增加。该发现揭示了皮肤拉伸反馈中的空间干扰机制，提示多通道可穿戴设备在设计时应避免将传感模块布置于紧密邻近区域，以维持感知效能。
原文摘要 · Abstract (English)
Proprioception is essential for coordinating human movements and enhancing the performance of assistive robotic devices. Skin stretch feedback, which closely aligns with natural proprioception mechanisms, presents a promising method for conveying proprioceptive information. To better understand the impact of interference on skin stretch perception, we conducted a user study with 30 participants that evaluated the effect of two simultaneous skin stretches on user perception. We observed that when participants experience simultaneous skin stretch stimuli, a masking effect occurs which deteriorates perception performance in the collocated skin stretch configurations. However, the perceived workload stays the same. These findings show that interference can affect the perception of skin stretch such that multi-channel skin stretch feedback designs should avoid locating modules in close proximity.
