  Abstract
  During the last three decades, there were more than a thousand of Chinese input methods have been developed, however people are still looking for better input method in terms of both easy to use, easy to remember, high input speed and small keypad implementation on handheld devices. The well-known stroke-based Chinese input method using only five basic stroke types could achieve low learning curve and small numeric keypad implementation but its input speed is limited for complex Chinese characters with a lot of strokes. To tackle this problem, simplified stroke-based Chinese character and phrase coding methods using (3+3) rules are proposed in this paper. The proposed simplified character coding method only uses the first 3 stroke codes and last 3 stroke codes to represent the first and last radical information of the character for achieving lower average code length and higher hit rate of first character on the candidate list. To further enhance the input speed, very user-friendly (3+3) phrase coding rule is also proposed for inputting Chinese phrases in the forms of 2-character, 3-character and multi-character phrases. Special QWERTY keyboard design is also proposed for two-hand input of the proposed Chinese character and phrase input. Experimental results have shown that the proposed character coding can achieve lower average code length and higher Hit Rate of First Character as compared with conventional stroke-based method and some well-known Chinese input methods. The proposed coding rules are also very easy to use and remember.
