The setting module 100 is configured to set an initial virtual keyboard 20 displayed on the touch screen 14 . As shown in FIG. 2, the initial virtual keyboard 20 includes, but is not limited to, virtual keys of all letters. In practical applications, the arrangement and distribution of the virtual keys in the virtual keyboard are not limited to the arrangement and distribution of the virtual keys shown in FIG.

The setting module 100 is further configured to set a single virtual button as a single word Separate symbol. The single-word separator symbol indicates that the next input letter is a pinyin letter of a new Chinese character, and is no longer a subsequent letter of the previous Chinese character. For example, the virtual button "|" in FIG. 2 is a single-word separator, but the actual application is not limited to the single-word separator shown in FIG. 2.

It should be noted that setting the word separator symbol can also facilitate the use of the following situations. For example, if the user needs to spell "Xi'an", that is, split into "XI" and "AN", instead of spelling "XIAN", the single-word separator symbol can be used for input.

The receiving module 102 is configured to receive a letter input by a user from the virtual keyboard after the electronic device 1 enters an edit state of the pinyin mode and the preset virtual keyboard 20 is displayed on the touch screen 14 String.

The determining module 104 is configured to determine whether the received letter or string is a set word separator.

The display module 106 is configured to refresh and display the set initial virtual keyboard 20 when the set single word separator is received.

The retrieval module 108 is configured to: when the received single word separation symbol is received, retrieve the Chinese character font 120 in the storage device 12 according to the received letter, and determine whether the Chinese character font 120 is included in the received The letter begins with the kanji pinyin.

The processing module 110 is configured to return a prompt information to the user when the Chinese character font 120 does not include the Chinese character pinyin beginning with the received letter, to prompt the user whether to input an error, and continue to receive the user's input. For example, the prompt information "Unable to retrieve the corresponding Chinese pinyin" can be displayed in the input interface, and the user can continue to input or modify the received letters.

The processing module 110 is further configured to: when the Chinese character font 120 retrieves the pinyin including the Chinese character beginning with the received letter, confirm the next one after the received letter in the retrieved Chinese pinyin Legal letter. In the preferred embodiment, the next letter of the confirmation is simply referred to as "matching letter". For example, according to the pinyin combination of Chinese characters, when spelling Chinese characters beginning with the letter "X", the pinyin letters beginning with "X" are followed by only "I" and "U", which can be combined with X to form a legal Chinese pinyin. "I" and "U" are referred to as "matching letters" beginning with the letter "X".

The display module 106 is further configured to display only the virtual keys corresponding to the matching letters on the virtual keyboard on the touch screen 14 after confirming the matching letters, thereby enabling the user to conveniently and conveniently from the virtual keys displayed on the virtual keyboard. Select the letter you want to enter.

The determining module 104 is further configured to determine whether the input is completed. If the input has been completed, for example, receiving a button command to send information or a button command to exit the editing state, it is confirmed that the current editing has been input; otherwise, Not entered.

For example, referring to FIG. 2, the set initial virtual keyboard 20 displays only a single letter on each virtual key. If the received letter is X, the search module 108 retrieves the Chinese character font 120 as follows. The Chinese character pinyin at the beginning of X: xi, xia, xiao, xian, xiang, xie, xin, xing, xiong, xiu, xu, xuan, xue, the processing module 110 confirms the matching letter "i" starting with X, "u", the display module 106 displays only the virtual keys "i" and "u" on the virtual keyboard of the touch screen 14, and at this time, the virtual keyboard 20 is initialized to form the virtual keyboard 21, thereby prompting The user can select the next letter to be entered and complete the pinyin input. If the user inputs I again at this time, the received letter is XI, and the search module 108 retrieves the following Chinese pinyin beginning with XI from the Chinese character font 120: xia, xiao, xian, xiang, xie, xin, xing , xiong, xiu; The processing module 110 confirms the matching letters "a", "e", "n", "o", and "u" starting with XI; the display module 106 displays only the virtual button on the touch screen 14" a", "e", "n", "o", "u" are selected by the user, that is, the virtual keyboard at this time has become the form of the virtual keyboard 22. It should be noted that the manner in which the display module 106 displays the virtual keys on the touch screen 14 is not limited to the display mode in FIG. 2 .

3 is a flow chart of a preferred embodiment of the method for pinyin input of the present invention. In step S110, the setting module 100 sets an initial virtual keyboard 20 displayed on the touch screen 14 and sets a single virtual key as a single word separator.

In step S112, the determining module 104 determines whether the received letter or string is a set word separator. When the set single word separator is received, the process proceeds to step S113; when the received word separator is not received, the process proceeds to step S114.

In step S113, the display module 106 refreshes and displays the set initial virtual keyboard 20, and then the process returns to S111.

Step S114, based on the received letters, the retrieval module 108 retrieves the Chinese character font 120 in the storage device 12, and determines whether the Chinese character font 120 includes Chinese character pinyin beginning with the received letter.

Step S115, when the Chinese character font 120 does not include the Chinese character pinyin beginning with the received letter, the processing module 110 returns a prompt information to the user to prompt the user to input an error, and proceeds to step S117. For example, the prompt can be displayed in the input interface The message "Cannot retrieve the corresponding Chinese Pinyin", the user can continue to input or modify the entered letters.

Step S116, when the Chinese character font 120 retrieves the Chinese character pinyin including the received letter, the processing module 110 confirms the next legal letter located after the received letter in the retrieved Chinese pinyin. In the preferred embodiment, the next letter of the confirmation is simply referred to as “matching letter”, and the display module 106 displays on the touch screen 14 only the virtual keyboard corresponding to the matching letter and continues to receive the user. Input.

In step S117, the determining module 104 determines whether the input is completed. If the input has been completed, for example, receiving a button command to send information or a button command to exit the editing state, the process ends; otherwise, if the input is not completed, the process returns. In step S111, the letter or string input by the user is continuously received.
