Cost-Benefit Analysis Reference Framework for Human Motion Capture and Analysis Systems

摘要

Athlete performance motion analysis was mostly qualitative in nature in the last two decades. However, computerized human motion analysis for athlete are becoming more prevalent with the recent advancement of technology which is related to input acquisition sensor, computer hardware,and algorithms. In this study, a novel cost-benefit analysis reference framework is proposed to evaluate the strength and tradeoff of various human motion capture and analysis systems in terms of cost, ease of implementation and expected results. The framework also helps us to determine themost suitable candidate technology for a real badminton coaching case study. The study reveals that the consumer grade markerless based technology is the most feasible given its strength in low startup and operating cost, minimal configuration, portability albeit with some compromise in resultaccuracy. Furthermore, the evaluation reference framework will benefit practitioners and researchers alike in sports biomechanics.
