GPS-assisted Indoor Pedestrian Dead Reckoning
Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies, 2022Indoor pedestrian dead reckoning (PDR) using embedded inertial sensors in smartphones has been actively studied in the ubicomp community. However, PDR relying only on inertial sensors suffers from the accumulation of errors from the sensors.

Speed estimation for pedestrian dead-reckoning
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010In this paper a new speed estimation method for pedestrian dead-reckoning is presented. The proposed approach is based on the estimated channel frequency response of Digital Video Broadcasting-Terrestrial (DVB-T) signals. Correlation coefficients are calculated from the acquired envelopes and the coherence time is estimated for a certain correlation ...

Strap-down Pedestrian Dead-Reckoning system
2011 International Conference on Indoor Positioning and Indoor Navigation, 2011This paper presents a waist-worn Pedestrian Dead Reckoning (PDR) System that requires minimal end-user calibration. The PDR system is based on an Inertial Measurement Unit (IMU) comprising of a tri-axial accelerometer, a tri-axial magnetometer and a tri-axial gyroscope.
