Markerless human motion capture-based exercise feedback system to increase efficacy and safety of elder exercise routines

—We developed a novel markerless motion capture system and explored its use in documenting elder exercise routines in a health club. We present two case studies of elders using a treadmill from our pilot work. Results demonstrate that our system is capable of providing important feedback about the posture and stability of elders while they are performing exercises. Our participants indicated that feedback from this system would add value to their exercise routines.
