用软体机器人把故事情绪变手感，触感随情感变化
Literary Emotions in Motion: A Soft Robotics Installation for Tactile Storytelling
- 用自然语言模型识别文本情绪，控制气动软体模块刚度
- 7个六边形排列的模块，中心主情绪，周围次情绪，可调刚度范围大
- 触感+灯光联动提升情绪感知，适合艺术装置与沉浸式体验
软体机器人在艺术领域应用日益广泛，其触觉交互可带来超越视觉与听觉的具身参与。本文提出一个互动装置，将叙事文本的语义情绪分析结果映射为软气动模块的可变刚度。通过自然语言模型从预设六种情绪中识别出两种主导情绪，驱动七个六边形排列的软致动器：中央致动器表示主要情绪，周围致动器表达次要情绪。我们设计并机械表征了硅胶软模块，采用薄膜层结构，在保持简单低成本制造的同时扩展了可实现的刚度范围。十名参与者参与的用户研究进一步评估了刚度与LED亮度多感官耦合对情绪感知的影响。结果表明，刚度调节配合颜色变化能有效支持情感意义明确且引人入胜的触觉交互，适用于软体机器人艺术装置。
原文摘要 · Abstract (English)
Soft robotics is increasingly explored in artistic contexts, where tactile interaction provides audiences with embodied engagement beyond visual or auditory signals. This work presents an interactive installation that maps semantic emotion analysis of narrative text into variable stiffness of soft pneumatic modules. A natural language model identifies two dominant emotions from a predefined set of six, driving the inflation of seven hexagonally arranged soft actuators. The central actuator represents the primary emotion, while the surrounding ones express the secondary. We develop and mechanically characterize silicone actuators, called soft modules, featuring a thin membrane layer, demonstrating how this morphological control expands the achievable stiffness range while preserving simplicity and low-cost fabrication. A user study with ten participants further evaluates how multisensory coupling of stiffness and LEDs intensity influences emotional perception. The results suggest that stiffness modulation accompanied by color change can support emotionally meaningful and engaging tactile interaction in soft robotic installations.
