Method and system for identifying handwriting track

The disclosure is related to a method for identifying handwriting track and a system thereof. The system includes a handwriting device and the control circuits, and the function modules for sensing angular velocity, data sampling, and track comparison. The system samples signals generated by the handwriting device as receiving the angular velocity signals. Multiple sampling values within a period of time are obtained. In addition to acquiring the data relating rotation and movement, a rhythm indicating the relationship among the multiple sampling values is also obtained. A handwriting track is depicted according to the angular velocity and angular displacement for every sampling point. The attribute of the handwriting track is therefore with the rhythm data recording variance of sampling values per unit time. The system renders modes of handwriting recognition, and character or command input.
