“…We first modified the notion of what a stroke is and designed a combined way of looking up a logograph. Previous work based on an idea similar to ours has been done [Hsu 1991], but the research target in that case was different. We will discuss this work further after explaining our method.…”

We have developed a method that makes it easier for language novices to look up Japanese and Chinese logographs. Instead of using the arbitrary conventions of logographs, this method is based on three simple prototypes: horizontal, vertical, and other strokes. For example, the code for the logograph (ta, meaning rice field) is 3-3-0, indicating the logograph consists of three horizontal strokes and three vertical strokes. Such codes allow a novice to look up logographs even with no knowledge of the logographic conventions used by native speakers. To make the search easier, a complex logograph can be looked up via the components making up the logograph. We conducted a user evaluation of this system and found that novices could look up logographs with fewer failures with our system than with conventional methods.

“…The minimum functional unit in Chinese is called a character, which is a blend of sound, structure, and meaning. In general, Chinese input methods can be classified as pronunciation-, structure-or arbitrarybased coding schemes [2]. For mobile phones, the typical input methods include the predominant pronunciation-based Pinyin method and various structure-based methods such as the iTAP ® solution (referred to as "stroke method" hereafter) developed by Motorola Inc.…”

Developing more effective and efficient Chinese character input methods has the potential to help Chinese mobile phone users (currently 320 millions) input text messages. iTAP(R) supports input based on the writing structure of Chinese characters. Current keypad graphics include three items: digits (0-9), letters (A-Z), and symbols that represent the minimum writing units of Chinese characters (strokes). Our study revealed the difficulties of mapping these strokes to individual keys using the current symbols. We present a case study illustrating the user-centered redesign of these symbols. The new symbols allow for faster entry speeds and lower error rates as compared to the current commercial solution. Results with our solution were also favorable when compared to Pinyin, a popular crosscultural solution relying on the Roman alphabet. The new design is in the process of being integrated into commercial mobile phones for users who would prefer native input methods for Chinese.

“…One of the major subjects in "Chinese Computing" is about how to input Chinese characters into the computer efficiently. These methods are known as Chinese input methods [1][2][3][4][5][6][7] and over a thousand of Chinese input methods have been developed. Each method has its own strengths and weaknesses in terms of learning curve, input speed and handheld device applications.…”

Abstract-During the last three decades, more than one thousand Chinese input methods have been developed. However, people are still looking for better input methods in terms of easy to use, easy to remember, high input speed and small keypad implementation on handheld devices. The well-known strokebased 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 method only uses the first 3 stroke codes and the 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, a very user-friendly (3+3) phrase coding rule is also proposed for inputting Chinese phrases in terms of 2-character, 3-character and long-character phrases. Three special key assignment designs are developed for practical implementation of the proposed Chinese character and phrase input method using conventional QWERTY keyboard, PC's numeric keypad and mobile phone 12-key keypad. 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.
