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.

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 ...

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.

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

A hybrid indoor navigation system
Proceedings of the 6th international conference on Intelligent user interfaces, 2001We describe a hybrid building navigation system consisting of stationary information booths and a mobile communication infrastructure feeding small portable devices. The graphical presentations for both the booths and the mobile devices are generated from a common source and for the common task of way finding, but they use different techniques to ...

Indoor sign Detection System for Indoor Assistance Navigation
2021 18th International Multi-Conference on Systems, Signals & Devices (SSD), 2021Indoor signage plays an important role in finding specific destinations and way-finding especially for blind and visually impaired people (VIP). In this paper, we developed a new indoor signage classifier using deep convolutional neural Network (DCNN).

Indoor Navigation with Minimal Infrastructure
2007 4th Workshop on Positioning, Navigation and Communication, 2007We describe an indoor navigation system based on dead reckoning localization, "augmented photos", and interactive methods that simplify the process of orientation. Our navigator does not require a fixed infrastructure for the recalibration of inertial data but it can improve its performance if a minimal localization infrastructure is available.

Open Specification for Indoor-Navigation
2017 IEEE 11th International Conference on Semantic Computing (ICSC), 2017Recent trends in mobile development have driven smartphones to become multipurpose devices engineeredto improve day to day activities. Due to their multi-functionality, smartphones have gradually evolved to replace traditionalinstruments as an all-in-one digital companions, but remain constrained by their sensory awareness.
