跟踪步行的人的位置的导航系统对于寻找和营救消防员或其他紧急第一响应者、或者对于位置感知计算、个人导航辅助、移动的3D音频以及混合或增强现实应用是有用的。包括混合现实（MR）在内的位置敏感可穿戴计算的现实部署的主要障碍之一是，当前的位置跟踪技术需要仪表化、标记化或预映射的环境。在InterSense，我们开发了一个名为NavShoe的系统，它使用一种基于惯性传感的位置跟踪新方法。我们的无线惯性传感器足够小，可以很容易地塞进鞋带里，而且功耗足够低，可以用一个小电池运行一整天。虽然它不能单独用于近距离物体的精确配准，但在增强远距离物体的户外应用中，用户几乎不会注意到NavShoe的米级误差以及头部相对于脚部的假设位置的任何误差。NavShoe可以大大减少计算机视觉的数据库搜索空间，使其更简单，更强大。NavShoe设备不仅提供了强大的近似位置，而且还提供了一个非常精确的足部方向跟踪器。
A navigation system that tracks the location of a person on foot is useful for finding and rescuing firefighters or other emergency first responders, or for location-aware computing, personal navigation assistance, mobile 3D audio, and mixed or augmented reality applications. One of the main obstacles to the real-world deployment of location-sensitive wearable computing, including mixed reality (MR), is that current position-tracking technologies require an instrumented, marked, or premapped environment. At InterSense, we've developed a system called NavShoe, which uses a new approach to position tracking based on inertial sensing. Our wireless inertial sensor is small enough to easily tuck into the shoelaces, and sufficiently low power to run all day on a small battery. Although it can't be used alone for precise registration of close-range objects, in outdoor applications augmenting distant objects, a user would barely notice the NavShoe's meter-level error combined with any error in the head's assumed location relative to the foot. NavShoe can greatly reduce the database search space for computer vision, making it much simpler and more robust. The NavShoe device provides not only robust approximate position, but also an extremely accurate orientation tracker on the foot.
