Ultrasound-aided pedestrian dead reckoning for indoor navigation [PDF]
Proceedings of the first ACM international workshop on Mobile entity localization and tracking in GPS-less environments, 2008 Ad hoc solutions for tracking and providing navigation support to emergency response teams is an important and safety-critical challenge. We propose a navigation system based on a combination of foot-mounted inertial sensors and ultrasound beacons. We evaluate experimentally the performance of our dead reckoning system in different environments and for

Vision-aided indoor pedestrian dead reckoning [PDF]
2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018 Vision-aided inertial navigation has become a very popular method for indoor navigation recently. This popularity is basically due to the development of light-weighted and low-cost Micro Electro-Mechanical Systems (MEMS) as well as advancement and availability of Charged-Couple-Device (CCD) cameras in public indoor areas.
