摘要：
One embodiment provides a system for analyzing a motion. During operation, the system obtains acceleration data associated with the motion. The acceleration data can include three components corresponding to three spatially orthogonal directions. For each orthogonal direction, the system computes an amount of oscillatory energy included in the motion in the orthogonal direction based on a corresponding acceleration component. For at least one orthogonal direction, the system obtains an energy fraction factor by computing a ratio between the amount of the oscillatory energy in the orthogonal direction and a total amount of the oscillator energy. The system generates a motion-analysis output based at least on the energy fraction factor.
