Indoor space subdivision for indoor navigation
Proceedings of the Sixth ACM SIGSPATIAL International Workshop on Indoor Spatial Awareness - ISA '14, 2014There are a number of great attempts to develop an indoor navigation that provide the most optimal path and guidance. Finding a way in large buildings can be a challenging task. In order to represent the real situation to a maximum extent, a representation of the whole room as one single indivisible object is not enough as such representation is very ...

NaviGates: A Benchmark for Indoor Navigation
Robotics 98, 1998Reliable indoor navigation has been a goal of mobile robotics research in recent years. Probabilistic belief update, occupancy grid methods, and multi-tiered hybrid architectures have all been implemented in the pursuit of autonomous navigation systems that can function in the face of danger and incomplete information. The conventional approach applies

Proceedings of the 12th international ACM SIGACCESS conference on Computers and accessibility, 2010
This research focuses on designing an indoor navigation application for disabled users. Outdoor navigation systems make use of GPS satellites to locate users; this same technique, however, is not reliable enough for indoor way-finding. Indoor Positioning Systems (IPS) exist but rely on complex and expensive networks.

Geohash Based Indoor Navigation
2020In order to reduce the dimension of coordinate information and locate quickly, the Geohash algorithm which was used for outdoor navigation originally, is extended to the indoor navigation. It divides the indoor space into many grids for finding optimal path and combines eight-direction maze for obtaining obstacle avoidance function.

Indoor geolocation by inertial navigation
2011 - MILCOM 2011 Military Communications Conference, 2011An inertial navigation system enhanced by a particle filter based on a dynamic motion model is shown to provide accurate indoor geolocation of a user despite no pre-installed infrastructure inside the building, no external assets, no environmental information, and no other information other than the geographical extent of the building.

Indoor magnetic navigation for the blind
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012Indoor navigation technology is needed to support seamless mobility for the visually impaired. This paper describes the construction of and evaluation of a navigation system that infers the users' location using only magnetic sensing. It is well known that the environments within steel frame structures are subject to significant magnetic distortions ...

Magnetic Maps for Indoor Navigation
IEEE Transactions on Instrumentation and Measurement, 2011Magnetic field fluctuations and anomalies inside buildings tend to have a great effect on the compass, which is one of the simplest navigation devices. Alternative navigation requires landmark identification, so those landmarks can be used as guideposts in assisting individuals.

TinySLAM improvements for indoor navigation
2016 IEEE International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI), 2016TinySLAM [1] is one of the most simple SLAM methods but the original implementation [2] is based on the specific robot model and provided as the ad-hoc application. Its key feature is simplicity of implementation and configuration at cost of accuracy (as our tests shown). Some changes were made in the original algorithm in order to minimize an error of

Indoor Precise Infrared Navigation
2020 27th International Conference on Mixed Design of Integrated Circuits and System (MIXDES), 2020The paper proposes an original solution enabling the navigation of a blind person in such buildings as shopping malls and offices as well as public and private institutions. A GPS system fitted with an infrared sensor in the form of a camera is used for navigation. The system detects the surrounding walls in buildings and enables a blind person to keep

The iNAV Indoor Navigation System
2007COMPASS is a location framework where location sources are realized as plugins that contribute probability density functions to the overall localization result. In addition, COMPASS uses a decentralized location-based service discovery based on Peer-2-Peer distributed hashtables to retrieve semantical data on the determined position.
