Radio Frequency (RF) fingerprinting, based on WiFi is a popular approach for indoor localization and it was attracting many research efforts in the past decades. However, most of the system is mainly focused on absolute positioning, but ignoring one important aspect that if the system is applied to a mobile phone, movement is constrained because of human native behavior. If we combine the method of continuous positioning with the fingerprint, the tracked location will be estimated more reasonable instead of being positioned in a strange place. In our system, we introduce an approach that makes use of fingerprint for navigation and we believe that such method is closer to the actual. Our system utilizes the sensors on mobile phones and is designed to run in a compact environment. With little human interaction except carrying mobile phones, the system reaches a satisfactory result.
