Research Abstract

We have developed a gate passing detection method based on WiFi signal strength and accelerometer of the user’s smartphone. Door divides physical areas such as room and hallway. Thus, the WiFi environments of them tend to vary on a large scale. Conversely, it can be said that a gate should exist when the point that the WiFi environment varies on a large scale. We define such point “WiFi Significant Point.” We propose the detection method based on WiFi distance function and estimated moving distance according to accelerometer. We evaluated the proposal method and found out that more than half part of door passing can be detected. We also found that the existence of doors that can be estimated same door passing with a high degree of accuracy
