Human locomotion is a nonlinear quasi-periodic process with chaos resulting from latent human musculoskeletal dynamics. The proposed methods were tested and validated by experiments, and the real-time applicability in a human locomotion capture system was also validated. After thorough analysis of the parameters and the effect of these improving techniques, we propose a novel prediction method that possesses the combined advantages of parameter robustness, high accuracy, trajectory smoothness, zero dead time, and adaptability to irregularities. With Takens’ reconstruction framework, we developed improving methods, including Gaussian coefficient weighting and offset correction (which is based on the smoothness of human locomotion), Kalman fusion with complementary joint data prediction and united source of historical embedding generation (which is synergy-inspired), and Kalman fusion with the Newton-based method with a velocity and acceleration high-gain observer (also based on smoothness).

Takens’ reconstruction method can well characterize quasi-periodicity and nonlinear systems. Human locomotion is a synergetic process of the musculoskeletal system characterized by smoothness, high nonlinearity, and quasi-periodicity.

In this paper, we use previous and current inertial measurement unit readings to predict human locomotion based on their kinematic properties. Inertial measurement units have been widely used for this purpose, although delay is a major challenge for inertial measurement unit-based motion capture systems. Human motion detection is of fundamental importance for control of human–robot coupled systems such as exoskeletal robots.
