Special Issue Information

Dear Colleagues,

Advances in wearable sensor technologies have revolutionized the way we monitor and analyse human movement, enabling breakthroughs across various domains, including healthcare, sports, human–computer interaction, and robotics. Wearable sensors, such as inertial measurement units (IMUs), tactile sensors, optical sensors, and biosensors, have become essential tools for tracking human position, attitude, and motion with high precision, portability, and real-time capabilities. These technologies offer unprecedented opportunities for personalized monitoring, rehabilitation, and performance optimization in dynamic and diverse environments.

This Special Issue of Electronics focuses on the design, implementation, and applications of wearable sensor systems for human position, attitude, and motion tracking. It highlights cutting-edge research and interdisciplinary approaches for addressing challenges in sensor design, data processing, and integration.

This paper presents a Virtual Reality (VR)-based kyudo form practice system using wearable inertial measurement unit (IMU) sensors and hand tracking to support solo training of Syaho-Hassetsu (the eight shooting stages). The system estimates the practitioner’s motion, segments it into stages with a time-aware finite-state machine, and provides stage-specific visual guidance inside a head-mounted display. To reduce individual differences, the system introduces a simple user measurement (fingertip-to-body midline length) to scale key distances such as stance width and draw length thresholds. The implementation is built in Unity and designed for real-time use on a standalone VR headset connected to an external motion-sensing pipeline. We position this work as a system-implementation and feasibility study: rather than asserting training effectiveness, our aim is to demonstrate that the proposed system can be realized and to report initial feasibility observations. In a small preliminary evaluation, results suggest VR guidance may improve stance-width consistency, and we treat these findings as feasibility evidence rather than conclusive proof of effectiveness.

Human kinematic analysis is an increasingly important tool in biomechanics, human performance, and wearable sensing research. Many emerging sensing modalities utilize custom sensors requiring accurate temporal alignment with ground-truth biomechanical movement data. Optical motion capture systems provide high-fidelity kinematic measurements but operate as closed, self-contained systems, making time synchronization with external sensor data non-trivial, particularly in wireless and mobile contexts. This work presents a wireless analog interface system built using commercially available components that enables alignment between analog sensor data (e.g., from custom wearables and Internet-of-Things devices) and a commercial motion capture system. The proposed architecture consists of a wearable data acquisition node and a receiver node interfaced directly with an optical motion capture system, allowing synchronized recording of analog sensor signals alongside kinematic data. Notably, the system reconstructs signals into the commercial hardware interface rather than relying on triggers or sync outputs, resulting in a single data file containing kinematics and sensor readings. Benchtop testing demonstrated a mean end-to-end frame delay of ~6 ms, with 95% of the sample exhibiting delay within 15 ms. Accounting for the typical offset, this leaves a standard deviation of 4 ms, within one motion capture frame of the true timestamp (at 100 Hz). Voltage reconstruction accuracy was within 30 mV across the tested conditions, with gain compression below 2.7%. Adjacent channel crosstalk remained below −83 dB across all test conditions. The use of commercial off-the-shelf components supports replication and adaptation by other research groups and integration with different optical motion capture systems. Full article
