把机器触觉的陌生感当成设计优势，让触感更有表现力。
Otherness as a Quality in Designing Expressive Robotic Touch
- 将机器人触觉的'异质性'视为可设计的特质，而非真实性的缺陷。
- 通过艺术与设计案例提炼出三类表达触觉意义的设计语言。
- 适合探索情感化人机交互、艺术装置或非现实主义机器人设计者。
触觉技术发展迅速，但机器人触觉设计仍以模仿真实环境线索或手势为主，限制了创新空间并可能引发社会抵触。本文主张另辟蹊径：基于人机交互中的“异质性”概念，将机器人触觉固有的‘陌生感’视为一种设计品质。不追求逼真，而是利用这种异质性制造模糊性，激发多重解读，推动更具表现力和感染力的触觉设计。通过反思性设计研究（RtD）方法，分析艺术与设计先例及四个设计案例，我们归纳出三组设计语言：阐明异质性在触觉意义建构中的重要性、如何通过设计策略塑造异质性，以及其在机器人触觉系统中的嵌入路径。最后，反思以异质性为核心设计时面临的张力与风险。
原文摘要 · Abstract (English)
Haptic technologies have advanced rapidly, yet exploration of robotic touch remains dominated by replicating realistic environmental cues or hand gestures, which narrows the design space and risks social resistance. This paper argues for alternatives: grounded in the notion of "otherness" from human-robot interaction (HRI), we propose treating robotic touch's inherent otherness as a design quality. Instead of being a limitation in pursuing realism, otherness can be embraced to elicit ambiguity and provoke alternative interpretations, fostering expressive and evocative robotic touch design. To develop this perspective, we analyze inspirational art and design precedents and four design research cases through a reflective Research through Design (RtD) approach. Through this analysis, we articulate a set of design languages structured around why otherness matters for touch meaning-making, how it can be shaped through design strategies, and where it can be embedded within robotic touch systems. We conclude by reflecting on the tensions and risks involved in designing robotic touch with otherness in mind.
