我们展示了Calmables，一个即走即用的闭环红外耳戴式设备演示，该设备利用智能戒指的心率数据来产生微妙的、耳部局部的升温提示。基于热舒适性和耳内红外刺激方面的已有研究，Calmables探索将耳部温暖作为一种生物信号自适应提示，用于急性激活后的短暂恢复时刻。首先，智能手机建立个体静息基线并推导出个性化心率阈值，而耳戴式设备控制器独立执行过热切断和通信故障安全机制。在引导式演示流程中，参与者完成一个短暂的快速呼吸激活阶段，直到其心率达到个性化阈值。这会触发耳部局部升温提示，随后进入短暂的放松阶段，同时生理变化显示在实时仪表板上。参与者还可以手动探索不同的红外刺激强度。为了给演示提供背景，我们报告了来自18名参与者的初步安慰剂对照用户体验评分：参与者对主动原型在感知放松和感知恢复支持方面的评分高于外观相同的安慰剂。总之，该演示展示了红外耳戴式设备如何通过微妙的、生物信号自适应的热提示使生理反馈变得可感知。
英文摘要
We present Calmables, a walk-up demo of a closed-loop infrared earable that uses smart-ring heart rate to create subtle, ear-localized warming cues. Building on work on thermal comfort and in-ear infrared stimulation, Calmables explores warmth at the ear as a biosignal-adaptive cue for brief recovery moments following acute activation. A smartphone first establishes an individual resting baseline and derives a personalized heart-rate threshold, while the earable controller independently enforces an over-temperature cut-off and communication fail-safes. During the guided demo flow, attendees complete a brief rapid-breathing activation phase until their heart rate reaches the personalized threshold. This triggers an ear-localized warming cue followed by a short relaxation phase, while physiological changes are displayed on a live dashboard. Attendees can also manually explore different infrared stimulation intensities. To contextualize the demo, we report preliminary placebo-controlled UX ratings from 18 participants: participants rated the active prototype higher on perceived relaxation and perceived recovery support than an identical-looking placebo. Together, the demo illustrates how infrared earables can make physiological feedback tangible through subtle, biosignal-adaptive thermal cues.
