环境智能旨在实现感知和利用我们周围信息的环境，而不需要我们感知底层系统。这项工作扩展了这一概念，让我们能够立即跟踪人和物体的运动和方向。所提出的系统可以感知并让我们知道，例如，谁经常见面或交谈，他/她在会议中经常面对谁，人们经常使用什么东西，这个人把他/她的物品留在哪里等等。这些信息将有助于系统了解每个人的行为模式，从而可以支持和改善用户的个人生活，甚至他们的相互关系。本文提出了一种即时室内磁跟踪系统，使我们能够通过仅在人和物体上附加微型电子跟踪器来跟踪人和物体的运动和方向。原型跟踪器的尺寸仅为 25.4mm $\times25.4$ mm $\times10.0$ mm，因此它可以轻松连接到几乎任何东西并立即激活。评估结果表明，所提出的系统适用于房间尺度跟踪和具有 6 DoF（自由度）的桌面尺度跟踪。
Ambient intelligence aims to actualize the environment that sense and utilize information around us without making us perceive the underlying systems. This work extends this concept by allowing us to track the movement and orientation of people and objects instantly. The proposed system can sense and let us know, for example, who met or talked to each other frequently, to whom s/he is often facing in the meeting, what stuffs people often use, where the person left his/her belongings, etc. Such information will help the system to understand the behavior patterns of each person and consequently can support and improve the personal life of users and even their mutual relationship. This article proposes an instant indoor magnetic tracking system that enables us to track the movement and orientation of people and objects by only attaching tiny electronic trackers to them. The size of the prototyped tracker is only 25.4mm $\times25.4$ mm $\times10.0$ mm, and hence it can be readily attached to almost anything and immediately activated. Evaluation results show that the proposed system applies to both room-scale tracking and tabletop scale tracking with 6 DoF (Degrees of Freedom).
