Visual Real-time Data Processing

Finite state machine impedance control method has been applied extensively in prosthesis control. However, extensive parametric configurations are required. Forthermore, there is no uniform official joint trajectory curve available which must therefore be obtained through virtual constraints. Following complete data processing, parameter configuration is needed to adjust appropriate joint trajectory, and is extremely time intensive. This article provides a smarter GUI interface for data processing. A curve fitting method that can be modified in real time is proposed. This curve fitting method is based on Bezier least squares method and uses MATLAB software to construct a visual GUI with certain generalization ability. The final smooth curve data can be extracted. Experimental data is derived from the knee and ankle trajectories of human motion.
