The Stroke Count Method , Wubihua method, Stroke input method or Bihua IME is a relatively simple Chinese input method for writing text on a computer or a mobile phone. It is based on the stroke order of a word, not pronunciation. It uses five or six buttons, and is often placed on a numerical keypad. Although it is possible to input Traditional Chinese characters with this method, this method is often associated with Simplified Chinese characters. The Wubihua method should not be confused with the Wubi method.
Each of the five keys from 1 to 5 are assigned a certain type of stroke with each character of this phrase being a one-syllable description of the respective five strokes:
To input any character, the user simply presses the keys corresponding to the strokes of a character then select from a list of matching characters. The list of suggestions to choose from becomes more and more specific as more digits of the code are entered. The system will not recognize a character input with an incorrect stroke order. Some people find this method of entering characters into a mobile phone to be faster than pinyin. In fact, as pinyin is based upon Mandarin Chinese, many Chinese people – particularly in the southern regions of China like Hong Kong and Macau – who speak other varieties of Chinese and never learned pinyin relied solely on this method of entering characters on their phones, until touchscreen-based Smartphones allowed the possibility of Handwriting recognition.
Wubihua is one of the easiest to learn methods because it is simple and does not require knowledge of pronunciation or Pinyin. However, it tends to be vague, as a Wubihua code will normally match ten characters, and each character has one correct code, which confuses users whose stroke orders are wrong.
