摘要: This paper presents a positioning system for "people-centric" navigation, which estimates relative positions of surrounding people to help users find target person in crowd neighbors. Our system, called PCN, employs pedestrian dead reckoning (PDR) and proximity sensing with Bluetooth only using off-the-shelf mobile phones. Utilizing the feature "group activity" where naturally form groups moving similarly together exhibitions, parties so on, PCN corrects deviation distance direction PDR. The group information is also helpful identify navigation. A field experiment real exhibition 20 examinees carrying Google Android phones was conducted show its effectiveness.
