20.500.12556/RUL-169843 Lightweight periodic scheduler in wearable devices for real-time biofeedback systems in sports and physical rehabilitation This study explores the application of wireless wearable devices within the emerging domain of biomechanical feedback systems for sports and rehabilitation. A critical aspect of these systems is the need for real-time operation, where wearable devices must execute multiple processes concurrently while ensuring specific tasks are performed within precise time constraints. To address this challenge, we developed a specialized, lightweight periodic scheduler for microcontrollers. Extensive testing under various conditions demonstrated that sensor sampling frequencies of 650 Hz and 1750 Hz are achievable when utilizing one and 26 sensor samples per packet, respectively. Receiver delays were observed to be a few milliseconds or more, depending on the application scenario. These findings offer practical guidelines for developers and practitioners working with realtime biomechanical feedback systems. By optimizing sensor sampling frequencies and packet configurations, our approach enables more responsive and accurate feedback for athletes and patients, improving the reliability of motion analysis, rehabilitation monitoring, and training assessments. Additionally, we outline the limitations of such systems in terms of transmission delays and jitter, providing insights into their feasibility for different real-world applications. wearable devices periodic scheduler senosrs IMU microcontroller real-time biofeedback sport physical rehabilitation nosljive naprave periodični odpravnik senzorji IMU mikrokrmilnik biomehanska povratna povezava v realnem času šport fizična rehablitacija true false true Angleški jezik Slovenski jezik Članek v reviji 2025-06-12 12:11:33 2025-06-12 12:11:41 2025-06-13 04:33:43 0000-00-00 00:00:00 2025 0 0 20 str. issue 12, art. 6405 Vol. 15 Jun-2 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.9 2076-3417 10.3390/app15126405 239145475 applsci-15-06405.pdf applsci-15-06405.pdf 1 EA0FC094D75D590997BBAAEE3CB64205 d11311cb5d95a7536a2fac33073d1d90281137df4e8a1ed7db634111b865ea02 ffedb01e-4775-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211571 https://www.mdpi.com/2076-3417/15/12/6405 1 24c1ea88-4774-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211568 Fakulteta za elektrotehniko 0 0 0
