The Tibetan input coding method of the present invention adopts a keyboard compatible with the Tibetan, and the number keys on the keyboard correspond to the Tibetan numerals one by one, input sequentially according to the Tibetan writing order and rules, use phonetic-graphic code input, use Tibetan Chinese vowel letters, participle symbols, sentence symbols or spaces are used as a sign of the end of a unit word input, and the end position of the character is automatically judged during continuous input. The keys of the keyboard define Tibetan letters according to the following regulations.

The first row: the three keys from left to right are three superscripts:

The fourth key to the seventh key correspond to four Tibetan letters in turn:

The eighth key to the tenth key are four subscripts:

And the letters of the first row of keys are used in conjunction with other Tibetan characters, not alone;

The Tibetan characters corresponding to the first to eleventh keys in the second row of keys are:

The Tibetan characters corresponding to the first to eleventh keys in the third row of keys are:

The Tibetan input coding method of the present invention is designed based on windows, and consists of a conversion interface and a user interface. The conversion interface is an interface function, these functions are called by the IMM, and the user interface receives messages and provides a user interface.

The Tibetan input coding method of the present invention is characterized in that the Tibetan code table file and the IME file are combined into one, and the array corresponding to the keyboard code and the character code is defined inside the IME file. Such an implementation mechanism can load the code table file and IME file into the memory at one time, and the access speed is fast

The keyboard used in the present invention is characterized in that the keyboard is a general-purpose keyboard, and the numeric keys on it are the same as the Tibetan numerals.

One-to-one correspondence, each letter and symbol key on the keyboard defines Tibetan letters according to the following regulations: The three keys of QWE are three superscripts:

The three keys of IOP are four subscripts:

其余各键位按如下排列：The four keys of RTYU correspond to four Tibetan letters:

The remaining keys are arranged as follows:

Accompanying drawing is the keyboard layout table of Tibetan letter coding of the present invention.

Detailed ways

Tibetan is an alphabetic script consisting of thirty consonants, four vowels, ten numbers and several special symbols. in:

Consonants:

vowel:

number:

other symbols

Add words:

Add words:

十个字母为后加字；在十个后加字中

五个字母为前加字，

两个字母为又后加字。对大量藏文文稿的统计得知藏文辅音字母(基字符)的频度顺序为：Thirty consonants in Tibetan

Ten letters are suffixes; in ten suffixes

Five letters are prefixed,

Two letters are added after. According to the statistics of a large number of Tibetan manuscripts, the frequency order of Tibetan consonant letters (basic characters) is as follows:

Therefore, when locating the keyboard layout, the positioning of Tibetan consonant letters is the core of Tibetan keyboard layout design, and the influence of Tibetan letter frequency on Tibetan input speed must be considered first. Based on this consideration, the Tibetan alphabet keyboard layout table shown in Figure 1 is obtained. In the Tibetan alphabet keyboard layout table shown in Figure 1, the three keys of QWE are three upper characters; the three keys of IOP are four lower characters; the four keys of RTYU correspond to four Tibetan letters. And this layout can better realize the rational layout of Tibetan letters, thereby making Tibetan under the premise of ensuring that touch typing can be realized, which is faster than the prior art.

In addition, in the Tibetan input coding of the present invention, vowel letters, participle symbols, sentence symbols, and spaces are used as the sign of the end of a unit word input, and the end position of the character can be automatically judged during continuous input, and the space bar is not used to end, so it can be Further improve the input speed of Tibetan.

The embodiment of the input method encoding of the present invention is designed based on the Windows Far East version, and consists of two interfaces: a conversion interface and a user interface. The conversion interface includes a series of interface functions, which are called by the IMM. The user interface consists of a set of windows that receive messages and provide the user interface. When the IME is started, the keyboard event is received by user.exe software, user.exe transmits the keyboard event to the Input Method Manager (IMM for short), and the manager then transmits the keyboard event to the IME input method , the input method translates keyboard events into corresponding characters (or strings) according to the user code dictionary, and then transmits them back to user.exe, and user.exe then transmits the translated keyboard events to the currently running application. Thus, the input of characters is completed.

The processing mechanism of the present invention is: when the user presses a certain key in the keyboard, the USER32 kernel of the system gets interrupted and responds to it, then sends the keyboard message to the SHELL message queue of the system, and this message is intercepted by the IMM, and the IMM processes the keyboard message and Select the currently active (ACTIVE) IME input method, and send the message to the IME input method. The main function is BOOL WINAPI ImeProcessKey (HIMC hIMC, UINT vKey, LPARAMlKeyData, CONST LPBYTE lpbKeyState). The events processed in the present invention mainly include IME key response and key end response, that is, IME_Keydownhandler and IME_Keyuphandler, which are executed after preprocessing, and the events that preprocessing thinks can affect the conversion process are processed. This input method does not respond to the key press event, that is, as long as the user presses a valid key, there will be a response without waiting for the key press to end. In input method keyboard processing, convert those keys that are considered legal in preprocessing and not processed by preprocessing, mainly including backspace key, ESC key, delete key, HOME key, END key, LEFT key, and RIGHT key And so on.

Since the Tibetan characters are only more than 600 characters, the code table is not huge. In the implementation of this input method, the code table file and the IME file are combined into one, and the array corresponding to the keyboard code and the character code is defined inside the IME file. Such as TibetInputTable array.

In the process of Tibetan input, if there are characters such as Tibetan vowel letters, participles, sentence symbols, and spaces, it can mark the end of Tibetan characters. For special symbols: "", (), etc., because these characters are used less frequently in Tibetan, two solutions can be used, one can be input through Chinese input methods.

The following is an example of inputting a set of Tibetan characters:
