增强现实/虚拟现实（AR/VR）头显吸引了数百万用户，并获得了可预测的普及。然而，沉浸式技术的长期使用可能导致健康问题（例如，电脑病、焦虑）。在这张海报中，我们设计了一个基于生命体征跟踪的低成本和个性化的医疗监护系统（即，呼吸和心率跟踪），通过利用内置的AR/VR运动传感器。关键的见解是，由胸部和心脏运动引起的传导振动可以通过用户的颅骨传播，从而振动安装在用户头部的AR/VR耳机。为了实现该系统，我们设计了信号处理技术，以消除人体运动，并通过频域分析得出呼吸和心跳的周期。我们进一步设计了一个基于呼吸和心脏生物特征的用户识别方案，该方案与生命体征监测一起工作，以提供个性化的医疗保健建议。实验结果表明，该算法在呼吸/心跳频率估计上的错误率小于5.7%，在用户身份识别上的准确率达到95%。
Augmented reality/virtual reality (AR/VR) headsets have attracted millions of users and gained predictable popularity. However, long-period usage of immersive technology may lead to health issues (e.g., cybersickness, anxiety). In this poster, we design a low-cost and personalized healthcare monitoring system grounded on vital sign tracking (i.e., breathing and heartbeat rate tracking), by exploiting built-in AR/VR motion sensors. The key insight is that the conductive vibrations induced by chest and heart movements can propagate through the user's cranial bones, thereby vibrating the AR/VR headset mounted on the user's head. To realize this system, we design signal processing techniques to cancel the human motions and derive the periods of breathing and heartbeat through frequency-domain analyses. We further design a user identification scheme based on respiratory and cardiac biometrics, which works with vital sign monitoring to provide personalized healthcare recommendations. Our experiment shows that the proposed scheme can achieve less than 5.7% error rate on breathing/heartbeat rate estimation and 95% accuracy on user identification.
