- 提出了一种基于WiFi信号强度和用户智能手机加速度计的过门检测方法。由于门分隔了房间和走廊等物理区域，因此WiFi环境往往会有很大的差异。当WiFi环境中的点大规模变化时，门应该存在。我们将这些点定义为WiFi显著点，并提出了一种基于WiFi距离函数和根据加速度计估计的移动距离的检测方法。我们评估了我们提出的方法，发现大多数门通过可以检测到。我们还发现，我们可以估计存在的门，具有相同的门通过具有高度的准确性。
—We propose a gate-passing detection method based on WiFi signal strength and the accelerometers of user smart-phones. Since doors divide such physical areas as rooms and hallways, the WiFi environments tend to greatly vary. A gate should exist when the points in the WiFi environments vary on a large scale. We define such points as WiFi significant points and propose a detection method based on a WiFi distance function and estimated moving distance according to an accelerometer. We evaluated our proposed method and found out that most door passings can be detected. We also found that we can estimate the existence of doors that have identical door passings with a high degree of accuracy.
