中文摘要：
提出了一种用户行为感知辅助的室内行人定位方法。该方法采用行为感知技术，通过智能手机内置的传感器获取行人经过室内特殊位置（如电梯、转角等）的连续多个位置相关的行为状态，结合室内路网的拓扑结构，将行人的位置匹配到相应的特殊位置，以消除行人航位推算（PDR）的累积误差，同时可以在起始点未知的情况下实现行人的自主定位。试验验证了该方法的有效性。
英文摘要：
Indoor pedestrian localization is the key factor in Location Based Service （LBS） applications. Meanwhile, Pedestrian Dead-Reckoning （PDR） is an important method for indoor pedestrian localization, and vulnerable to the accumulate errors. This paper proposes a user activity awareness assisted indoor pedestrian localization method, in which an activity awareness technique is used to detect a user＇s consecutive activities when the user passes special locations using the built-in sensors in smartphones. Based on the location-related activities and indoor road network topology, the accumulated PDR errors are eliminated by matching these consecutive activities to the special locations. Moreover, by the activity matching method, pedestrian autonomous localization can be realized when the starting point in unknown. Experimental results demonstrate the effectiveness of the proposed method.
