Recognition of the mode of motion or mode of transit of the user or platform carrying a device
is needed in portable navigation, as well as other technological domains. An extensive …

Microelectromechanical Systems (MEMS) technology is playing a key role in the design of
the new generation of smartphones. Thanks to their reduced size, reduced power …

The objective of this research is to improve traffic safety through collecting and distributing
up-to-date road surface condition information using mobile phones. Road surface condition …

Context is the environment that a navigation system operates in and the behaviour of its host
vehicle or user. The type and quality of signals and environmental features available for …

The next generation of navigation and positioning systems must provide greater accuracy
and reliability in a range of challenging environments to meet the needs of a variety of …

Due to the universal presence of motion, vibration, and shock, inertial motion sensors can be
applied in various contexts. Development of the microelectromechanical (MEMS) technology …

The main challenge in portable navigation is obtaining accurate positioning results in urban
canyons and indoors where global navigation satellite system signals are …

In this paper, an adaptive activity and environment recognition algorithm running on a
mobile phone is presented. The algorithm makes inferences based on sensor and radio …

In order to navigate or localize in 3D space such as parking garages, we would need height
information in addition to 2D position. Conventionally, an altimeter is used to get the floor …

Map-matching refers to the process of projecting positioning measurements to a location on
a digital road network map. It is an important element of intelligent transportation systems …
