ABSTRACT
Global positioning system (GPS) is widely used in vehicle navigation; however, they are unusable for pedestrians. Problems include inadequate information for optimized path-planning in the pedestrian level; and the human-computer interface (HCI) for vehicles basically does not work for walking user. This paper presents solutions to solve these problems through experiments. A new design of GPS based human navigation aid, called "City Walker", is proposed. CityWalker uses a digital fluxgate compass to rotate the map automatically, according to user's orientation. City-Walker thus provides a low-cost solution for building a GPS based, human oriented navigation tool on various mobile platforms.

Pedestrian Tracking with Shoe-Mounted Inertial Sensors
One of the main obstacles to the real-world deployment of location-sensitive wearable computing, including mixed reality, is that current position-tracking technologies require an instrumented, marked, or premapped environment, which is impractical in ...

The Kalman filter (KF) has been implemented as the primary integration scheme of the global positioning system (GPS) and inertial navigation systems (INS) for many land vehicle navigation and positioning applications. However, it has been reported that ...
Vehicle State Estimation System Aided by Inertial Sensors in GPS Navigation
ICECE '10: Proceedings of the 2010 International Conference on Electrical and Control EngineeringDespite the development of the GPS navigation system, problems still lies in two topics: GPS signal losses and unreliable positioning in the elevation direction. This paper proposes a vehicle state estimation system to produce integrate information ...
