To create a context-aware environment, human locations and movement paths must be considered. In this paper, we propose an algorithm that tracks human movement paths using only binary sensed data obtained by infrared (IR) sensors attached to the ceiling of a room. Our algorithm can estimate multiple human movement paths without a priori knowledge of the number of humans in the room. By repeating predictions and estimations of human positions and links from the previous human positions to the estimated ones at each time period, human movement paths can be estimated. Simulation-based evaluation results show that our algorithm can dynamically trace human movement paths.
为了创建一个上下文感知环境，必须考虑人类的位置和移动路径。在本文中，我们提出了一种算法，该算法仅使用安装在房间天花板上的红外（IR）传感器获得的二进制传感数据来跟踪人类移动路径。我们的算法无需事先了解房间内的人数就能估计多条人类移动路径。通过在每个时间段重复预测和估计人类位置以及从前一个人类位置到估计位置的链接，可以估计人类移动路径。基于模拟的评估结果表明，我们的算法能够动态跟踪人类移动路径。
