Below introduce the flow process of character input, further to introduce the present invention, in following introduction, microswitch 24 is triggered by roller 22 controls.
3 * 4 keyboards for existing mobile phone are shown K1～K9, K at this with each key table
*, K0, K#, respectively corresponding numeral 1～9, *, 0, # on it is to be different from the different input of each key definition.The corresponding key of each symbolic representation is pressed (if the following key that illustrates that certain is not specific is represented with " KX ").
When needs are imported certain character, on existing cell phone keyboard, press corresponding KX key, keyboard 10 is just delivered to character processing unit 13 to the code of this key and is handled.Character processing unit 13 can be a software of further handling this bonded state herein, also may be software modules such as input in Chinese, English input.And on device of the present invention, in the time of need pressing KX, choose KX by the rotation of roller 22 after, press bottom roller 22 again and trigger microswitches 24, then the KX bonded state is sent to and character processing unit 62.And described character processing unit 13 has identical functions, identical interface with character processing unit 62.Therefore the present invention only need change the selection mode of character, and need not to change the processing mode of character.For KX key special operational on the existing keyboard, as double-click, long press etc., on new equipment as long as can realize by the same way as operation.Below will introduce the selection flow process of character.
Fig. 7 is the process flow diagram that the signal pulse of mobile phone characters input method of the present invention is handled.At first, pulse processing unit 63 is waited for the signal input (step S71) of pulse generation unit 64.When the signal pulse that receives from signal wire A or B, pulse processing unit 63 is at first carried out rough handling to signal pulse, as filtering etc.Judge whether input pulse rising (step S72) then into signal wire A.If the signal pulse of signal wire A rises, then the KX key signals (hereinafter to be referred as KX) with the input character correspondence adds 1 (step S74), and the pulse of waiting signal line B rises (step S76), then the pulse of waiting signal line A and signal wire B all descend (step S78).
If signal wire A does not have the rising pulse, then further judge whether the input pulse rising (step S73) of signal wire B.If do not have, then return step S71, continue the waiting signal input.If there is the pulse of signal wire B to rise, then pulse processing unit 63 subtracts 1 (step S75) with KX, and the pulse of waiting signal line A rising (step S77), forwards step S78 then to, and waiting signal line A, B descend.
Certainly, the judgement of the pulse of signal wire A and signal wire B also can be adopted the pulse of judging signal wire B earlier, judges the pulse of signal wire B again, perhaps adopts interrupt mode to judge.Above-mentioned polling mode and interrupt mode all belong to prior art, do not give unnecessary details at this.
Then, pulse processing unit 63 is further judged microswitch 24 whether be triggered (step S79).If microswitch 24 is triggered, promptly roller 22 is pressed, and then pulse processing unit 63 sends to character processing unit 62 with the KX value, character processing unit 62 is accepted corresponding input, and be shown in display unit 61 (step S80), and return step S71 then, wait for the input of next character.If microswitch 24 is not triggered, then return step S71.
In step S78, can be by the human-computer interaction interface of display unit 61, character display is selected to confirm for the user, promptly when KX increases, moves after the current character order; When KX reduced, current character moved forward in proper order.At current character location triggered microswitch 24, promptly send the KX value to character processing unit 62, the value of input current character.
Fig. 8 selects the process flow diagram of character for the signal pulse that utilizes of mobile phone characters input method of the present invention.Input process below in conjunction with case introduction numeral and letter.
When being input as numeral, need to suppose input digit " 5 ", promptly the key of Xuan Zeing is K5.Pulse processing unit 63 is sent an initial value to character processing unit 62 earlier, for example be K1 (corresponding numeral " 1 "), at this moment, character processing unit 62 is handled this key, and is showing " 1 " (because the input mode of this moment is the numeral input) by display unit 61.As rotation roller 22 (step S82), being assumed to be order rotates, then the moving lattice pulse processing unit 63 of revolution is sent one " removing " to character processing unit 62 and is ordered, is used for to remove numeral " 1 " (this process is finished jointly by character processing unit 62 and display unit 61), send key K2 again, and display digit " 2 ".Repeat this process, to be sent (step S83) up to K5.This moment, the numeral " 5 " of display unit 61 demonstrations was the numeral of required input, trigger microswitch 24 (step S84), K5 is sent to character processing unit 62 (step S85), decontrol microswitch (step S86) then, send microswitch 24 and decontrol signal to character processing unit 62 (step S87), and wait for that roller rotates, to import next numeral (step S81).
At present the input media of mobile phone be by be distributed in 26 letters on 8 keys, each key comprises 3～4 English alphabets, when pressing certain key one time, import first letter, when pressing once more at certain time intervals, second letter, original letter are eliminated on this key of input on the same position; If supress another key or overtime official hour at interval, then should letter by software be defined as input, next button will be imported at the next position.These processing procedures are in fact all finished by character processing unit and display unit, and keyboard and corresponding software only are responsible for the selection of letter, promptly use the push button signalling of transmission in real time of button.In fact, each key also may comprise the situation more than 3 or 4 letters, for example, and the capitalization of 3 letters, the small letter of adding 3 letters and Greek alphabet etc.With letter " B " be input as example, existing mobile phone to be adopted by twice K2 key, imports the key of next non-K2 again or waits for a period of time (for example 5 seconds), then this letter is transfused to
Similarly, when input alphabet the time, the present invention at first shows letter " A " (can certainly be other letters) at the input position of display unit 61, pass through rotation roller, move to letter " B " position, after triggering twice microswitch, letter " B " is transfused to, and pulse processing unit is also sent two K2 key assignments to character processing unit 62.When rotation roller once more, be equivalent to supress another key beyond the K2, then letter " B " is identified input.
In the present invention, except said method, can also be directly in display unit 61 order show letter " ABCabc ... " wait all letters on this K2 key, after pressing bottom roller, from the letter that wherein select to need, directly import, significantly reduced the number of times of button again as capitalization English letter " B ".
Another kind of disposal route is, revolution moves a lattice roller, and A-B-C-D pressed in current letter ... variation successively, when the letter of needs is shown, then confirm the input of this character by bottom roller.12 lattice when being equivalent to input digit have become 26 lattice of input alphabet, and other process is identical during with input digit.
From the process of top input alphabet as seen, in fact the present invention with which kind of language of input has nothing to do, and its care is transfused to the position of key.When input Chinese, no matter be different input methods such as phonetic, stroke, radical, the user always presses a series of buttons based on order, and on new equipment, correspond to the sequence of operations of " rotate---press " roller, as long as the order of the KX of input conformed to existing cell phone keyboard with the time interval.
For example, with spelling input method import Chinese words " in ", on existing cell phone keyboard inputting English letter " ZHONG ", from the phonetically similar word that demonstrates, select this word to get final product then; In the present invention, also as long as the monogram of order input " ZHONG ", equally again by function key select " in " word gets final product.
For other any special input method,, basic irrelevant or relation is very little with pulse processing unit 63 because mainly be character processing unit 62 and the modification of display unit 61.Therefore, the present invention can adapt to the input of existing all numerals, literal, character etc.
