Abstract
A method for identifying reference points in a hand drawing track with a number (n) of dots includes marking a first one of the dots as a reference point; for each of a (kth) one of the dots, determining an included angle; marking the (kth) one of the dots as a reference point when the included angle associated therewith is larger than a predetermined angle; calculating an accumulated distance between the (kth) one of the dots and a last one of the reference point (s) thus marked when the included angle is not larger than the predetermined angle; and marking the (kth) one of the dots as a reference point when it is determined that the accumulated distance thus calculated is larger than the predetermined distance, 2≤k≤(n−1).
