用脑控让机器人实时模仿患者运动，提升康复互动体验。
Brain-Robot Interface for Exercise Mimicry
- 通过脑机接口解析意图，实现机器人对患者动作的实时模仿。
- 14人实验中12次成功模仿，参与者信任度与接受度高。
- 适合康复训练场景，尤其利于运动功能障碍患者长期坚持锻炼。
为使社交机器人作为长期锻炼指导者保持用户参与度，建立情感联结至关重要。在社交互动中采用动作模仿（如模仿对方身体动作）是增强亲密度的有效手段，该方法在康复训练中广泛应用，患者会模仿理疗师或视频示范的动作。本文开发了一种新型脑-机器人接口（BRI），使社交机器人教练能够基于患者意图的脑信号实时模仿其锻炼动作。研究在14名参与者（3名理疗师、11名中风或其他损伤后恢复期的偏瘫患者）中进行了探索性评估。结果显示，系统在12次试验中成功实现动作模仿，但准确性存在差异。参与者对机器人教练整体评价积极，信任度和接受度高，且引入BRI技术未对其感知产生负面影响。
原文摘要 · Abstract (English)
For social robots to maintain long-term engagement as exercise instructors, rapport-building is essential. Motor mimicry--imitating one's physical actions--during social interaction has long been recognized as a powerful tool for fostering rapport, and it is widely used in rehabilitation exercises where patients mirror a physiotherapist or video demonstration. We developed a novel Brain-Robot Interface (BRI) that allows a social robot instructor to mimic a patient's exercise movements in real-time, using mental commands derived from the patient's intention. The system was evaluated in an exploratory study with 14 participants (3 physiotherapists and 11 hemiparetic patients recovering from stroke or other injuries). We found our system successfully demonstrated exercise mimicry in 12 sessions; however, accuracy varied. Participants had positive perceptions of the robot instructor, with high trust and acceptance levels, which were not affected by the introduction of BRI technology.
