This invention discloses a method for Chinese character input combining eye-tracking and P300 technology. The method utilizes the spatial modulation information of the eye-tracking device to select a mode: the eye-tracking device collects the user's visual trajectory in real time, obtaining the coordinates of the user's eye movement points. When the user gazes at the start option, the system detects this intention and generates a command to activate the spelling process. Combining the eye-tracking device and P300 technology, the initials and finals of the Chinese characters are selected. The method then integrates with a Pinyin input method to achieve the function of inputting Chinese characters: after selecting the initials and finals, the user switches to the Pinyin input method, selects the target Chinese character, and thus achieves the Chinese character input function. This invention, combining eye-tracking and P300 technology for Chinese character input, allows users to achieve computer typing functions without taking any action, relying solely on their eyes and brain. Furthermore, the use of a standard Chinese input method's character library enables matching Chinese characters after spelling. This expands the scope of assistive devices for people with movement disorders beyond computer devices themselves, and has significant practical implications.

The invention discloses an optimized phonetic and sequential code simplified and traditional Chinese character input method which is a computer Chinese character input method with phonetic codes as main codes and shape codes as auxiliary codes. In the input method, the common coding form of Chinese characters is phonetic codes and shape codes, the shape codes are used for eliminating repeated codes in combination with character frequency, syllable representative characters only have phonetic codes and do not have shape codes, and the shape codes of other Chinese characters are gradually increased along with reduction of the character frequency. The Pinyin input method comprises intelligent Pinyin, has many repeated codes, and is low in efficiency due to character selection. A five-stroke character input method and other phonetic and morphological code input methods are high in learning cost and difficult to grasp. The input method is simple and easy to learn, can be learned immediately, and has the characteristics that word-by-word input is emphasized, word input is not rejected, Chinese characters, words and punctuation marks can be typed in a touch manner, and the input experience is smooth; traditional Chinese characters also have sound and shape codes, so that the requirements of different people can be met, and Chinese character culture transmission is facilitated; the method is close to the reality of Chinese characters, and when the manuscripts are drawn out through a computer, interference on thoughts is little.
