Multi-Sensor Edge Angle Detection for Performance Analysis in Ski Jumping
Ivan Simeonov, Lukas Schulthess, Hanna Mueller +4
In ski jumping, performance during the gliding phase depends on achieving an aerodynamic posture that maximizes the lift-to-drag ratio. In the V-style technique, the ski edge angle…
A Time-Synchronized Video Reference System for Data Analysis of Body-Attached Sensor Nodes in Outdoor Scenarios
Lukas Schulthess, Fabian Pleisch, Matheo Käch +4
Wearable body-attached multi-sensor systems enable detailed analysis of human motion and physiological signals in sports, rehabilitation, and movement research. While wireless sync…
Wireless Low-Latency Synchronization for Body-Worn Multi-Node Systems in Sports
Nico Krull, Lukas Schulthess, Michele Magno +2
Biomechanical data acquisition in sports demands sub-millisecond synchronization across distributed body-worn sensor nodes. This study evaluates and characterizes the Enhanced Shoc…
