本研究提出经皮颈迷走神经刺激（tcVNS）作为隐式干预，实验显示其使进食量减少9.6%、速度降低23.6%，验证了非侵入性刺激管理饮食行为的可行性。
AI 中文摘要
暴饮暴食和情绪化进食是常见的健康问题，即使没有进食障碍的人也会受到影响。迷走神经在肠-脑轴中起着关键作用，植入式迷走神经刺激器已被证明与食欲下降相关。在本文中，我们提出将经皮颈迷走神经刺激（tcVNS）作为一种普适系统，在进食发作期间提供即时、低努力的干预。在一项包含24名参与者的研究中，我们在一次分心零食进食过程中评估了一款移动手持式tcVNS设备。我们发现，与假刺激相比，参与者在迷走神经刺激期间进食量减少了9.6%，进食速度降低了23.6%。两种条件下的餐后饱腹感相同，而迷走神经刺激期间心率较低。刺激被描述为微妙且几乎不可察觉。总体而言，这些结果为非侵入性迷走神经刺激作为管理饮食行为的低注意力干预措施的可行性提供了证据——这种干预可以封装在普适交互系统中。因此，我们将隐式界面的设计空间扩展到生理干预，为未来将进食相关感知与低注意力干预相结合的普适系统铺平了道路。
英文摘要
Overeating and emotional eating are common health issues that affect people even without an eating disorder. The vagus nerve plays a critical role in the gut-brain axis, and implanted vagus nerve stimulators have been associated with reduced appetite. In this paper, we propose transcutaneous cervical vagus nerve stimulation (tcVNS) as a ubiquitous system to provide immediate, low-effort intervention during an eating episode. In a study with 24 participants, we evaluated a mobile, handheld tcVNS device during a single episode of distracted snacking. We found that participants ate 9.6% less and 23.6% more slowly during vagus nerve stimulation than during sham stimulation. Post-snacking satiety was the same in both conditions, while heart rate was lower during vagus nerve stimulation. The stimulation was described as subtle and barely noticeable. Overall, these results provide evidence for the feasibility of non-invasive vagus nerve stimulation as a low-attention intervention for managing eating behavior -- one that can be packaged inside ubiquitous interactive systems. As such, we extend the design space of implicit interfaces toward physiological intervention, motivating future ubiquitous systems that pair eating-related sensing with low-attention interventions.
