标题： Easing Seasickness through Attention Redirection with a Mindfulness-Based Brain--Computer Interface

摘要： 晕船是一种普遍的问题，对乘客的体验和海事船员的操作效率都有不利影响。 虽然在陆地环境中，转移注意力的技术已被证明能有效缓解运动病症状，但由于海上旅行相关的长时间和强烈的运动环境，将类似策略应用于管理晕船面临独特的挑战。 在本研究中，我们提出了一种正念脑机接口（BCI），专门设计用于转移注意力，以减轻现实环境中的晕船症状。 我们的系统使用单通道头带捕捉前额叶脑电图（EEG）信号，并通过无线传输到计算设备，以评估正念状态。 结果以正念分数和视听刺激的形式实时反馈，促进注意力从生理不适转移到正念练习上。 共有43名参与者参加了一个由三个阶段组成的现实海上实验：真实反馈正念阶段、休息阶段和伪反馈正念阶段。 值得注意的是，81.39%的参与者表示正念BCI干预是有效的，且根据痛苦量表（MISC）测量的晕船严重程度有显著降低。 此外，脑电图分析显示θ/β比值下降，与晕船症状的缓解相对应。 在真实反馈正念阶段，总体脑电波段功率的下降表明，正念BCI促进了大脑活动更为平静和下调的状态。 总之，本研究提出了一个新颖的非药物、便携且有效的晕船干预方法，有望提升乘客和船员的航行体验。 显示英文摘要

摘要： Seasickness is a prevalent issue that adversely impacts both passenger experiences and the operational efficiency of maritime crews. While techniques that redirect attention have proven effective in alleviating motion sickness symptoms in terrestrial environments, applying similar strategies to manage seasickness poses unique challenges due to the prolonged and intense motion environment associated with maritime travel. In this study, we propose a mindfulness brain-computer interface (BCI), specifically designed to redirect attention with the aim of mitigating seasickness symptoms in real-world settings. Our system utilizes a single-channel headband to capture prefrontal EEG signals, which are then wirelessly transmitted to computing devices for the assessment of mindfulness states. The results are transferred into real-time feedback as mindfulness scores and audiovisual stimuli, facilitating a shift in attentional focus from physiological discomfort to mindfulness practices. A total of 43 individuals participated in a real-world maritime experiment consisted of three sessions: a real-feedback mindfulness session, a resting session, and a pseudofeedback mindfulness session. Notably, 81.39% of participants reported that the mindfulness BCI intervention was effective, and there was a significant reduction in the severity of seasickness, as measured by the Misery Scale (MISC). Furthermore, EEG analysis revealed a decrease in the theta/beta ratio, corresponding with the alleviation of seasickness symptoms. A decrease in overall EEG band power during the real-feedback mindfulness session suggests that the mindfulness BCI fosters a more tranquil and downregulated state of brain activity. Together, this study presents a novel nonpharmacological, portable, and effective approach for seasickness intervention, with the potential to enhance the cruising experience for both passengers and crews.
