Special Issue Information

Dear Colleagues,

Computational Discovery: Complementing Diversity through Sensor Technology' refers to a comprehensive technology that maximizes practical effectiveness and efficiency through data collection and analysis using sensors in various fields. As sensors become more sophisticated and generalized, various application technologies are being developed and distributed not only in specialized fields but also more generally real life. In addition, digital twin technologies using VR, AR, XR, MR, etc., can be simulated to prepare for environments with sensors that are difficult or dangerous to apply right away in the real world, reducing the difference between real and virtual environments. In particular, effective application technologies are being developed in various fields such as medicine, environmental monitoring, and smart city development, and more accurate system models and predictability are presented through various data inputs. In other words, Computing Discovery: Complementing Diversity through Sensor Technology' will lead technological innovation while protecting the full potential of sensor technology from unintended consequences.

For example, the field of advanced sensor networks is the study of the design and development of sensor networks in the field of edge and fog computing. The field of multi-sensor data fusion technology studies how to improve the accuracy and reliability of computational models by integrating data from different types of sensors. The field of machine learning for AI and sensor data can apply machine learning technology to analyze complex datasets from sensors, with an emphasis on improving model performance and reducing bias. The field of smart city innovation is being studied to investigate how to use sensor networks to create smarter urban environments and improve infrastructure, transportation, and public services. At this time, unexpected risk factors can be reduced by performing various simulations before actually creating a smart city by applying digital twin technology.

In this Special Issue, we welcome research on various methods and application technologies carried out using sensor technology. In particular, we request studies or academic papers on practical development technologies using machine learning, deep learning, and big data. Topics of particular interest are as follows:

  • Multimodal Data Fusion Techniques;
  • Real-Time Data Processing Algorithms;
  • Digital Twin using VR, MR, XR and AR;
  • Empirical Systems and Applications using Digital Twin;
  • Bias Detection and Mitigation in Sensor Data;
  • Machine Learning for Sensor Data;
  • Applications in Healthcare Monitoring;
  • Environmental Monitoring;
  • Smart City Innovations using Sensors;
  • Human-Computer Interaction with Sensors;
  • Technology for Autonomous Vehicles;
  • Systems or Applications using IoT (Internet of Things) and IoE (Internet of Everything);
  • Fog/Edge Computing.

Abstract
Accurate golf swing correction requires modeling not only static pose deviations but also temporal rhythm and biomechanical stability throughout the swing sequence. Most existing pose-based approaches rely on frame-wise similarity and therefore fail to capture timing, velocity transitions, and coordinated joint dynamics. This [...] Read more.
Accurate golf swing correction requires modeling not only static pose deviations but also temporal rhythm and biomechanical stability throughout the swing sequence. Most existing pose-based approaches rely on frame-wise similarity and therefore fail to capture timing, velocity transitions, and coordinated joint dynamics. This study proposes a reinforcement learning-based framework that generates frame-level corrective motions by formulating swing correction as a sequential decision-making problem optimized via Proximal Policy Optimization (PPO). A multi-term reward function is designed to integrate geometric pose accuracy, incremental correction improvement, hip-centered stability, and temporal rhythm consistency measured using a Velocity-DTW metric. Experiments conducted with swing sequences from one professional and five amateur golfers demonstrate that the proposed method produces smoother and more temporally coherent corrections than static pose–based baselines. In particular, rhythm-aware rewards substantially improve the motion of highly dynamic joints, such as the wrists and shoulders, while preserving lower-body stability. Visual analyses further confirm that the corrected trajectories follow expert patterns in both spatial alignment and timing. These results indicate that explicitly incorporating temporal rhythm within a reinforcement learning framework is essential for realistic and effective swing correction. The proposed method provides a principled foundation for automated, expert-level coaching systems in golf and other dynamic sports requiring temporally coordinated whole-body motion. Full article
