Input method for Chinese character coding efficiency of the two comparative studies

Article, a statistical and computational results are as follows: 4,1 test article Total characters 1036 words, with the spelling input, keystrokes Σ: 2920 (second), the average Chinese character input key code length = 2.8 / words; with five-stroke input, keystrokes Σwb = 2504 (times), the average Chinese character input L = 2.4 keys / keystrokes Wubi word spelling less than L4.25%. 42 consecutive keystrokes, the spelling of the number of combinations of keys C = 321 (species). Wubi's keys combinations = 541 (species), five strokes spelling more than 68,54%. 4.3 Quanpin theoretical input speed Sa. : 3483,0,[link widoczny dla zalogowanych], Wubi theoretical input speed b = 3460.0,[link widoczny dla zalogowanych], (keystroke time equivalent units). It can be seen in the theoretical speed of two input methods is almost the same. On the above conclusions we explained that: five-stroke Chinese characters by the split, reducing the number of keystrokes entered characters,[link widoczny dla zalogowanych], but the combination caused an increase in keys, especially the little finger and so \Chinese character input speed. Result, the theory of two input methods no significant difference between the input speed. Code input method for the introduction of Chinese character input, the impact of input efficiency reasons both movements have aspects of mental workload (mainly memory load) the reasons, both of the more important is the impact of mental workload. Our experiments verify this conclusion. Two methods by comparing the speed of theoretical input, we can see spelling and Wubi is basically no difference, in other words, the two methods in the action no significant load difference, resulting in major differences between the two input efficiency because the mental workload of two different input methods. 5 Conclusion and discussion based on the experimental tests and theoretical calculations, the wisdom of our spelling and intelligent new five-stroke input efficiency comparison, the following conclusions: In the limited training time, the spelling of the input speed and accuracy was higher for five pen; memory more difficult than spelling Wubi, Wubi also more likely to be forgotten; spelling and five strokes of the theory there was no significant difference between the input speed. Ergonomics June 1998 Volume 4, 2j Tc for this conclusion, there are caveats. First, our subjects were college students from selected reading out, cast the experience of a Chinese character input. In the experiment, the cumulative learning each time an input method 24h,[link widoczny dla zalogowanych], so the above conclusion does not apply to a professional typist. However, we believe that even if this result makes sense. Taking into account the popularity of computers with the vast majority of computer users are amateur typists, but they do not have time and energy to spend dozens of hours to learn a certain kind of special character input method. Second, the use Wubi as a Chinese character input method of the experiment does not mean that we think Wubi unscientific. In fact, Wubi is indeed a relatively good invention. We conducted this study should be noted that, in order to quickly spread a computer in China and to better play its significant role, the need to reduce the difficulty of learning to use computers. In this case, we believe that the spelling method and the direct relationship between the keyboard and less a man-made code, so the more worthy of recommendation to the general users. Third, the study found that under normal circumstances, the human rate of about 30 Chinese characters handwritten copies of J, so any Chinese character input system, users should ensure that proper training can be entered per minute under 30 characters. Our data show that, after 24h of practice, spelling, and two five-stroke input method, the fastest average speed of only 2l4 words / min, significantly lower than the speed of people's handwriting, indicating that need to be further reduced the threshold of the computer, which reduces the difficulty of inputting Chinese characters to learn the computer, a variety of Chinese character input method also needs further improvement References l Mrs Zhang Zhao, Xu force.
