在许多应用中，希望监测人体运动，以为康复、虚拟现实、运动科学等应用提供有用的信息。当今用于身体运动跟踪的大多数现有惯性/磁系统都带有限制自然运动的布线。在本文中，开发了一种使用加速度计的可穿戴无线传感器网络来监测人体运动。我们系统的无线功能允许无限制的移动并提高系统的可用性。此外，轻质传感器节点的使用使其易于附着在四肢上，并且对自然运动几乎没有阻碍。与使用多个摄像头的复杂视觉跟踪系统相比，所开发的系统还便于携带且成本低廉。传感器节点的低功耗也使其适合长期监控。研制了样机，实验结果表明该系统具有合理的性能。
In many applications, it is desired to monitor the human body motion to provide useful information for applications such as rehabilitation, virtual reality, sports science etc. Most existing inertial/magnetic systems used for body motion tracking today come with wiring which restrains the natural movement. In this paper, a wearable wireless sensor network using accelerometers has been developed for monitoring the human motion. The wireless feature of our system allows for unrestrained movements and improves the usability of the system. Moreover, the use of lightweight sensor nodes makes it easy for attachment to the limbs and poses little hindrance to natural movements. The developed system is also portable and low in cost compared to sophisticated visual tracking systems utilizing multiple cameras. The low power consumption of the sensor nodes also makes it suitable for long term monitoring. A prototype has been developed and experimental results show that the system has reasonable performance.
