The Astar algorithm, which forms the backbone of vehicle navigation systems, is capable of producing only one path. Given uncertainty about link travel times, there is interest in algorithms that can deliver all the paths that may be optimal, termed collec ...
This paper explores the usability requirements of a navigation system for older adults by identifying the key usability and ergonomic problems in existing navigation systems and proposing a set of new guidelines for designing such systems. We also discuss ...
This paper describes a new noninvasive brain-actuated wheelchair that relies on a P300 neurophysiological protocol and automated navigation. When in operation, the user faces a screen displaying a real-time virtual reconstruction of the scenario and concen ...

Self-localization of an underwater vehicle is particularly challenging due to the absence of Global Positioning System (GPS) reception or features at known positions that could otherwise have been used for position computation. Thus Autonomous Underwater V ...

The results of a field experiment carried out to assess the accuracy and efficiency of a new in-vehicle navigation algorithm, whose aim is to incorporate and consider travel time reliability and route the guided vehicle along uncongested roads, in the abse ...
Facing the expansion of geolocation needs, illustrated by the GALILEO European project, the growth of Location Based Services (LBS) and the need to identify the location of emergency mobile phone calls in Europe (standard E112), the research on localizatio ...
Today’s surgical navigation systems are difficult to use for deformable organs. State of the art technology struggles to continuously update and display preoperative information such that it corresponds to the actual position of the organ. An update method ...
The complementary nature of MEMS based pedestrian dead-reckoning (PDR) navigation and GNSS (Global Navigation Satellite System) has long been recognised. The advantages are quite clear for those applications requiring indoor positioning and that, for one r ...

This presentation describes the main ITS (Intelligent Trasnportion Systems) services and their requirements in positioning. Different types of navigation systems are presented with a focus on satellite-based systems and the potential of Galileo with value ...
Underwater navigation challenges the research community as a reliable navigation system is unavailable. Correctly matched landmarks could compensate the drift of dead reckoning navigation systems. Furthermore, they could be useful in side scan sonar image ...
