The advantages and disadvantages of different methods are analyzed, and a new method based on hand drawn speed is proposed. The method first of all has a certain frequency sampling user hand trajectory points and calculates the user's drawing speed, then according to the pen movement simulation speed calligraphy pen writing gets weight effect. Finally, in pen to put pen to paper and pen calligraphy peak effect, in order to achieve Chinese calligraphy writing simulation effect. Experimental results show that the method doesn't need rely on special handwritten device, only needs to collect user writing speed information, it can achieve better simulation effect of calligraphy writing, for the user to achieve calligraphy writing provide a new method.
