Quaternion-Averaging-Based Adaptive Complementary Filter for Pedestrian Dead Reckoning With a Foot-Mounted AHRS
Shunsei Yamagishi, Lei Jing
Pedestrian Dead Reckoning (PDR) can be applied to indoor navigation systems. GPS suffers from signal degradation due to roofs and high-rise buildings, whereas PDR can estimate posi…
Multimodal User Authentication Method via Fusion of Keystroke Dynamics and Glove-Based Hand Kinematics
Issei Hyakuda, Lei Jing
Although keystroke dynamics are cost-effective behavioral biometrics, their practical deployment is hindered by susceptibility to environmental variations. To address this, we prop…
A Lightweight Cubature Kalman Filter for Attitude and Heading Reference Systems Using Simplified Prediction Equations
Shunsei Yamagishi, Lei Jing
Attitude and Heading Reference Systems (AHRSs) are broadly applied wherever reliable orientation and motion sensing is required. In this paper, we present an improved Cubature Kalm…
WPTrack: A Wi-Fi and Pressure Insole Fusion System for Single Target Tracking
Wei Guo, Shunsei Yamagishi, Lei Jing
As the Internet of Things (IoT) continues to evolve, indoor location has become a critical element for enabling smart homes, behavioral monitoring, and elderly care. Existing WiFi-…
