Specific embodiments 1:
Double-deck button disclosed in the utility model, biggest advantage are can reduce touch potential in input characters, realize quick word selection.Now narrate the using method of double-deck keyboard in conjunction with the specific implementation 1 of Figure 21～24.
In the keyboard of traditional mobile phone, Personal Handyphone System, palmtop PC, 26 English alphabets are dispensed on 2～9 these 8 buttons.0 key, 1 key, * key, # key are because will bear functions such as switching input method, punctuation mark, switching pinyin and English combination, so they are not assigned to letter.On 2～9 these eight buttons, there are 6 keys to bear 3 letters, there are 2 keys to bear 4 letters, on average each key is born 3.25 letters.When this has just caused input English, phonetic, produce repeated code, influence input speed through regular meeting.
It is exactly that the stress word is very many that Chinese character also has characteristics.When therefore carrying out the Chinese character input, just need a frequent difficult problem in the face of word selection with spelling input method.At present the Word selection method on mobile phone, Personal Handyphone System, the palmtop PC mainly contains: one, directionkeys+determine key word selection; Two, determine key+number keyboard selecting character; Three, the long number keyboard selecting character of pressing.Directionkeys+determine that key word selection and these two kinds of word selection modes of definite key+number keyboard selecting character often need repeatedly button could select a Chinese character, and length is pressed the number keyboard selecting character misoperation because of the button deficiency of time easily, perhaps lose time because of the button overlong time, therefore a lot of people are difficult to adapt to.This shows, improve the speed of word selection on the mobile phone, become the key that improves the mobile phone text input speed.
Use the keyboard of double-deck button, its function is distributed as Figure 22 and shown in Figure 23.Wherein, the key in numerical key panel 20 all is double-deck button.As for delete key 21, directionkeys 22, OK key 23 with answer/and on-hook key 24 all is a common key-press, its function is also identical with button on the regular handset.Because the button in numerical key panel 20 is double-deckers, switch functions such as input method, punctuation mark, switching pinyin and English combination and be moved over to lower floor's button, the upper strata button of 0 key, 1 key, * key, # key then is released.Like this, 12 keys of upper strata button can be assigned to English alphabet, wherein, have 10 buttons to bear 2 letters, have only 2 buttons to bear 3 letters, as shown in figure 22.Average each key is born 2.17 letters, and the letter that each button is born has lacked 1.08 than originally, and therefore, when carrying out the literal input with this keyboard, the repetition rate of coding can significantly reduce, and this is very great for literal input especially its meaning of input of Chinese.
In the present embodiment, in conjunction with the keyboard that double-deck button constitutes, the inventor has proposed a kind of brand-new word selection mode, promptly utilizes lower floor's button to carry out quick word selection.As shown in figure 23, lower floor's button of 1～8 these 8 keys is used to quick word selection.In the time of input Pinyin, on Chinese character, conveniently demonstrate with Chinese character one to one the numeral (as shown in figure 24).Do not need this moment by determining that key table shows that the phonetic input finishes by (on the mobile phone that uses common keyboard, this step 1 as be absolutely necessary), directly heavily just can choose Chinese character by numerical key 1～8.Chinese character of every like this input just can be pressed once even more times key than lacking on the common keyboard, therefore can improve input speed greatly.And heavily by the function of 0 key, * key, # key be respectively: the English combination of switching pinyin, punctuation mark, switching input method.Lower floor's key of 9 keys is not assigned with any function as yet, can be defined voluntarily by manufacturer or user.
In the above-described embodiment, if the keyboard that the double-deck button of the uncomfortable use of user constitutes, this keyboard is can be with the mode operation of compatible common keyboard.The user only needs in the default of mobile phone lower floor's button to be forbidden just passable.This moment, no matter the strength of button was to be greatly little, and system receives only the signal of upper strata button, and the signal of lower floor's button is ignored.At this moment the function of double-deck button is the same with common key-press, and the letter on the keyboard distributes also will revert to traditional method of salary distribution.The letter that be printed on the keyboard this moment is just different with actual letter distribution, may have influence on user's normal use.The method that solves is very simple, and the outer surface that only needs to be printed on alphabetical keyboard is replaced just passable with new keyboard outer surface.The mobile phone of at present a lot of models is all supported this function.
Under holding state, its function of flicking button is an input digit, heavily can be defined as multiple different shortcut function by button.
Specific embodiments 2:
Present embodiment has illustrated another comparatively desirable execution mode, as shown in figure 25.
