Special Issue Information

Dear Colleagues,

Wearable sensors for human-movement monitoring have a broad range of applications, including healthcare, wellbeing monitoring, rehabilitation, and human–computer interaction. Despite rapid advancements in wearable sensor technology and computational algorithms, significant research challenges remain. High-quality data are crucial for data-driven human-movement monitoring algorithms. While the research community strives to share collected data, challenges remain regarding the ability to learn from heterogeneous sources of data and information. Can trained models be transferred or adapted to new environments and contexts or even individuals? In the absence of sufficient real data, what roles and limitations do synthetic data play in enhancing model performance? Additionally, considering the demanding requirements for continuous monitoring and processing, how can green computing solutions improve energy efficiency and manage model complexity while ensuring data privacy, for example, when cloud-based infrastructure is deployed?

We invite researchers to contribute their latest research findings to this Special Issue. Topics of interest include, but are not limited to.

Inertial measurement units (IMU) are increasingly utilized to capture biomechanical measures such as joint kinematics outside traditional biomechanics laboratories. These wearable sensors have been proven to help clinicians and engineers monitor rehabilitation progress, improve prosthesis development, and record human performance in a variety of settings. The Valor IMU aims to offer a portable motion capture alternative to provide reliable and accurate joint kinematics when compared to industry gold standard optical motion capture cameras. However, IMUs can have disturbances in their measurements caused by magnetic fields, drift, and inappropriate calibration routines. Therefore, the purpose of this investigation is to validate the joint angles captured by the Valor IMU in comparison to an optical motion capture system across a variety of movements. Our findings showed mean absolute differences between Valor IMU and Vicon motion capture across all subjects’ joint angles. The tasks ranged from 1.81 degrees to 17.46 degrees, the root mean squared errors ranged from 1.89 degrees to 16.62 degrees, and interclass correlation coefficient agreements ranged from 0.57 to 0.99. The results in the current paper further promote the usage of the IMU system outside traditional biomechanical laboratories. Future examinations of this IMU should include smaller, modular IMUs with non-slip Velcro bands and further validation regarding transverse plane joint kinematics such as joint internal/external rotations.
