System for evaluating dynamic behavior

A system for evaluating dynamic behavior is adapted for solving the problem that a dynamic behavior performance/difference is evaluated by writing an evaluation form with an evaluator's subjective thoughts in the conventional evaluating method. The system comprises a dynamic information collecting device and a computer. The information collecting device has a supporting member and a sensing module. The supporting member has a supporting portion, and the sensing module is installed to the supporting portion. The computer has a processor coupled with the sensing module and executes the following evaluating steps: collecting a dynamic behavior data of an evaluated person during a sampling period; applying a Kalman filtering method to transform the dynamic behavior data to a filtering data; applying at least one dynamic analysis formula to transform the filtering data to a value; analyzing a differential value by calculating the difference between said value and a preset standard vale to determine whether said di
