Problems solved by technology

This greatly limits the usage environment and scenarios of related applications, causing many users to be reluctant to choose handwriting as their preferred input
[0012] On the other hand, handwriting varies widely from person to person, and the most excellent algorithm cannot guarantee the correct recognition of each Chinese character for each person
Recognition errors lead to additional operations or useless work, which not only reduces the efficiency of input, increases user fatigue, but more importantly, brings a lot of bad emotional experience to users

[0049] Chinese Pinyin is composed of initials and finals. And all finals can be divided into six families according to their initial letters: a, e, i, o, u, and ü, such as figure 1 shown. Therefore, the 35 finals are organized in the form of a final family, and as long as the user clicks on the first letter of a certain final, the menu of the finals of the letter family can be seen.

[0050] For example, when the user inputs "bright", when the user clicks the button "i", he can see the finals menu of the i family, including ia, ie, iu, in, iao, ian, ing, iang, etc., and then select the desired finals (" iang"), you can complete the pinyin input in one step according to the Chinese pinyin scheme.

[0051] A pie menu refers to a menu that expands around a focal point, usually in a circle. It's triggered, which means it only pops up when needed. After the menu appears, you can draw a ray pointing from the center of the circle to the menu item or click the menu item directly t...

no. 2 approach

[0071]The above first embodiment describes the input method of the present invention in the form of a virtual keyboard. But the present invention can be applied under the situation of hard keyboard equally. Attached below Figure 9 to Figure 1 3 to describe the method of the second embodiment of the present invention in detail. According to the second embodiment of the present invention, the handheld device is provided with a hard keyboard and a touch-operated touchpad disposed between the screen portion and the hard keyboard portion, and the spatial layout of the pie menu is mapped on the touchpad.

[0072] Figure 9 It is a flowchart explaining the Chinese character input method of the second embodiment of the present invention. like Figure 9 As shown, when the user inputs a Chinese character, first at step S20, the first letter of the pinyin of the Chinese character is pressed on the hard keyboard, for example, 'jkl' is pressed.

[0073] Then, in step S21, it is judge...

no. 3 approach

[0087] In both the first and second embodiments, the finals to be selected are displayed in the pie menu. But it is also possible to list possible Chinese pinyin in the form of a pie menu after the user presses a certain button. Attached below Figure 14 to Figure 1 8 to describe the method of the third embodiment of the present invention in detail.

[0088] Figure 14 A flow chart of the Chinese character input method according to the third embodiment of the present invention is shown. like Figure 14 As shown, in step S30, the user directly presses the button corresponding to the first pinyin letter of the Chinese character to be input on the soft keyboard or the hard keyboard, such as the button 'JKL' where the 'k' of the word 'kan' is located, and then In step S31, a pie pinyin menu pops up on the screen, in which part of the pinyin related to 'j', 'k' and 'l' is given. For example, only the first eight pinyin given according to the frequency table of Chinese characte...

Abstract

Disclosed is a method for utilizing an input device to input Chinese characters, comprising the steps: pressing the key of at least one letter in Chinese phonetic alphabets of a Chinese character required to be input on the input device; displaying at least one combined final correlated to the first final of at least one letter in the form of a pie menu; producing at least one Chinese phonetic alphabet from at least one letter and at least one combined final; selecting Chinese phonetic alphabets corresponding to the Chinese character from at least one Chinese phonetic alphabet; and identifying the selected Chinese phonetic alphabets as the corresponding Chinese character based on the Chinese phonetic alphabet proposal. The method can be utilized to reduce the keystrokes obviously when inputting Chinese characters.

Description

technical field [0001] The invention relates to a Chinese character input method, in particular to an input method based on a vowel menu, which can significantly reduce the number of keystrokes during Chinese character input. Background technique [0002] At present, mobile phone input is a low-efficiency and high-intensity exercise, which to some extent dampens the user's interest in using mobile phones for multi-text input, so that mobile phones can be used to more abundant applications (especially data applications, such as mobile blogs, key bottlenecks in the development of e-mail, mobile office, etc.). [0003] First of all, a mobile phone is a portable device. The nature of portable devices limits the expansion of the size of the mobile phone, which further affects the size and quantity of the key particles of the mobile phone keyboard. Too small button particles do not meet the optimal size required for manual operation, which seriously affects the comfort of operat...
